PLANNING YOUR INSTALLATION  
QUESTIONS TO ASK LOCAL BUILDING OFFICIAL  
A correct installation is critical and imperative for reduc-  
ing fire hazards and perilous conditions that can arise  
when wood burning appliances are improperly installed.  
The installer must follow all of the manufacturer's in-  
structions.  
FLOOR PROTECTION  
This appliance requires  
combustible approved fireplace hearth or hearth exten-  
sion. If the floor protection is to be stone, tile, brick,  
etc., it must be mortared or grouted to form a continu-  
ous non-combustible surface.  
a
heat resistant non-  
This protected area must extend a minimum of 18" (457  
mm) to the front of the fuel door opening and 8" (203  
mm) beyond both sides of the fuel door opening.  
The installation of a wood burning appliance must con-  
form to local codes and applicable state and federal  
requirements. Familiarity with these requirements be-  
fore installation is essential. Important considerations to  
discuss with local building officials include:  
HEARTH PROTECTION  
1.  
Applicable codes (i.e. Uniform Mechanical Code,  
State or Regional Codes)  
Electrical codes: The blower system has a  
flexible electrical cord that must be electrically  
grounded per local codes or per electrical codes:

CHIMNEY INSPECTION  
The existing fireplace should be inspected by a local fire  
marshal or qualified installer for adequate serviceability  
prior to installing this appliance.  
2. Local amendments?  
3. Is a permit required - cost?  
(You may wish to contact your insurance company  
to ask if they require this).  
4. Rooms where the installation is not allowed?  
Factory built fireplace (not approved in Canada): If  
any portion of the chimney system shows signs of  
structural or mechanical weaknesses, such as:  
cracks, leaky joints, corroded or warped surfaces.  
Look for obvious bulges in the lining, which may indi-  
cate the need to replace that section (use a bright  
flashlight. Any faulty portion must be repaired or re-  
placed prior to installing this appliance. Also, inspect  
the attic to see that the chimney has proper clearance  
to combustible framing members.  
SMOKE DETECTORS  
Since there are always several potential sources of fire  
in any home, we recommend installing smoke detec-  
tors. If possible, install the smoke detector in a hallway  
adjacent to the room (to reduce the possibility of occa-  
sional false activation from the heat produced by the  
fireplace insert). If your local code requires a smoke  
detector be installed within the same room, you must  
follow the requirements of your local code. Check with  
your local building department for requirements in your  
area.  
Masonry fireplace: The chimney should have no  
cracks, loose mortar, other signs of deterioration, or  
blockage. Any necessary repairs should be done by a  
qualified mason.  
If the existing fireplace flue system is dirty or has some  
obstruction in it, clean it. A dirty chimney can cause  
your insert to smoke when refueling, and can result in a  
chimney fire. An oversized chimney may result in less  
than optimum performance. Installations into a large  
masonry chimney may require a liner to improve per-  
formance.  
IMPORTANT – THIS APPLIANCE IS NOT AP-  
PROVED FOR INSTALLATION INTO A MANUFAC-  
TURED (MOBILE) HOME IN CANADA OR IN THE  
USA.

PLANNING YOUR INSTALLATION  
CLEARANCES  
DRAFT REQUIREMENTS  
The appliance is merely one component of a larger sys-  
tem. The other equally important component is the vent-  
ing system. This is necessary for achieving the required  
flow of combustion air to the fire chamber and for safely  
removing unwanted combustion byproducts from the  
appliance. If the venting system's design does not pro-  
mote these ends, the system may not function properly.  
Poorly functioning venting systems may create per-  
formance problems as well as be a safety hazard (i.e.  
an oversized chimney may result in less than optimum  
performance. Installations into a large, masonry chim-  
ney may require a liner to improve performance). A  
draft test should read greater than .04' W.C. (inches  
water column) and less than .08" W.C.  
WARNING: IT IS VERY IMPORTANT THAT YOU  
OBSERVE THE MINIMUM CLEARANCES. DO NOT  
STORE FIREWOOD WITHIN THIS CLEARANCE  
SPACE. FAILURE TO MAINTAIN CLEARANCES TO  
ALL COMBUSTIBLES MAY RESULT IN A HOUSE  
FIRE.  
There are listed clearances for your fireplace insert,  
which were determined in a Laboratory testing and  
must be maintained.

American National Standards Institute ANSI/NFPA 211-92,  
draft 1-7: A chimney or vent shall be so designed and con-  
structed to develop a flow sufficient to completely remove all  
flue and vent gases to the outside atmosphere. The venting  
system shall satisfy the draft requirements of the connected  
appliance in accordance with the manufacturer’s instructions.  
PROVIDE ADEQUATE AIR FOR COMBUSTION  
In well insulated and weather tight homes, it may be  
difficult to establish a good draft up your chimney. The  
poor draft is caused by a shortage of air in the house.  
To provide the needed air, crack a window on the wind-  
ward side of the house.  
VENTILATION REQUIREMENTS  
THE FRESH AIR REQUIREMENTS OF THIS APPLI-  
ANCE MUST BE MET WITHIN THE SPACE WHERE  
IT WILL BE INSTALLED.  
Ventilation is essential when using a solid fuel burning  
heater. The combustion process of this heater uses  
oxygen from inside the dwelling and it may be neces-  
sary to open a window or install a vent to provide make-  
up air into a dwelling that is well insulated (modern con-  
struction standards have resulted in homes that are  
highly energy-efficient and that allow little heat loss and  
air transfer). Other appliances in the dwelling also con-  
tribute to removing air from the dwelling (i.e. clothes  
dryers, exhaust fans, fireplaces, and other fuel burning  
appliances). If the available fresh air delivery in the  
dwelling is insufficient to support the demands of these  
appliances, problems can result (i.e. excessive negative  
pressure can develop in the dwelling which will affect  
the rate at which this appliance can draft. See Draft Re-  
quirements on this page).  
For installation with a combustible mantel or top trim,  
Part #16101 deflector must be installed.

FACTORY BUILT FIREPLACES  
Factory Built Fireplace Installation  
(Not Approved In Canada)  
In the USA, this appliance is approved for installation  
into a listed factory built solid fuel burning fireplace (built  
to UL 127 or ULC S610 standards). The fireplace fire-  
box must accept the insert without modification other  
than removing bolted or screwed together pieces such  
as smoke shelf / deflectors, ash lips, screen or door  
tracks and damper assemblies, that must be reinstalled  
to restore the fireplace to its original operating condition  
if the insert is removed and not replaced. The removal  
of any part must not alter the integrity or outer shell of  
the pre-engineered fireplace cabinet in any way.  
Venting Requirements for factory built fireplace:  
The fireplace damper must be secured in the open po-  
sition. This appliance requires the use of a 6” (152 mm)  
diameter flex or rigid, UL1777 listed 2100° HT liner or  
equivalent. The liner must extend from the flue outlet of  
the appliance to termination. Do not face seal over fire-  
place chimney cooling air systems. Offsets can be han-  
dled with an offset adapter (it aligns starter pipe with  
fireplace flue). For more information on the offset  
adapter, see pages 10 and 26.  
WARNING: DO NOT SUBSTITUTE THE HEAT  
RATED 2100°HT LINER WITH ANY OTHER TYPE  
LINE OR A FIRE MAY RESULT CAUSING PROP-  
ERTY DAMAGE, PERSONAL INJURY OR LOSS  
OF LIFE.

Offsets  
This appliance is approved for installation into a ma-  
sonry fireplace built to UBC 37 or ULC S628 standards.  
Do not remove brick or mortar form the masonry fire-  
place to accommodate this appliance. If the fireplace  
has been modified to accommodate the fireplace insert,  
a metal tag documenting what was modified must be  
attached to the fireplace (as required by Clause 5.1.11  
it must be secured using screws or nails to the fire-  
place, in a location readily visible should the fireplace  
insert be removed). The lettering shall not be less than  
5 mm high.  
Offsets can be handled with an offset adapter (it aligns  
starter pipe with fireplace flue). For more information  
on the offset adapter, see pages 10 and 26.  
FIREPLACE CHIMNEY MAXIMUM SIZE TO ENSURE  
PROPER DRAFT – USA ONLY  
Note: Installations in Canada require a full length liner.  
The fireplace insert flue size is 6 inches (152 mm) di-  
ameter, which is approximately 28 square inches (711  
square mm), the minimum. The maximum flue size  
should be no more than (3) three times the cross sec-  
tional area of the size of the fireplace insert flue collar.  
In this case, that would be no larger than a 10 inch (254  
mm) diameter stack (area = approx. 85 sq. inches [216  
sq. cm]).  
Metal Tag  
THIS FIREPLACE HAS BEEN ALTERED TO AC-  
COMMODATE

SON PRIOR TO RE-USE AS A CONVENTIONAL  
FIREPLACE  
Note: Formulas for calculating Area:  
IMPORTANT: Any opening between the masonry of  
the fireplace and the facing masonry must be per-  
manently sealed.  
Calculating area of a circle:  
π x r2 = Area (π = 3.1416, r = 1/2 diameter)  
USA Requirements / Masonry Fireplaces - The fire-  
place damper must be secured in the open position. In  
the USA, a flue extension past the fireplace header is  
required as a minimum. A preferred installation is a  
positive flue connection (sealing the throat of the chim-  
ney). This appliance requires the use of a 6” (152 mm)  
diameter flex or rigid single wall pipe, minimum 24 / 25  
MSG black or blued steel connector pipe (stainless  
steel recommended).  
To calculate area of square or rectangle:  
Width x Depth = Area  
Notes:  
It may be necessary to use a full-length liner to  
achieve adequate draft for the appliance. A draft  
gauge should read more than .04 W.C.I, but less than  
.08 W.C.I. for optimum performance.  
This appliance is approved for all heatform style  
fireplaces (masonry fireplace with a metal fire-  
box liner).  
Canada Requirements / Masonry Fireplaces - – This  
fireplace insert must be installed into an approved solid  
fuel Masonry fireplace only (installation into a factory  
built fireplace is not approved). The fireplace damper  
must be secured in the open position. The fireplace in-  
sert must be installed with a continuous chimney liner of  
6” / 152 mm diameter extending from the fireplace in-  
sert to the top of the chimney. The chimney liner must  
conform to the Class 3 requirements of CAN / ULC –  
S635, Standard for Lining Systems for Existing Masonry  
or Factory-Built Chimneys and Vents, or CAN / ULC –  
S640 Standard for Lining Systems for New Masonry  
Chimneys.

INSTALLATION  
POWER CORD CHANGEOVER  
MARBLE  
Marble is a natural product and therefore each piece will  
have its own unique character. Marble can be scratched  
so care should be taken to avoid putting heavy or rough  
objects (trivet / steamers) on the surface. Do not install  
the marble before curing the paint.  
DANGER: Risk of electrical shock. Disconnect  
power before servicing appliance. Do not route  
power cord under or in front of appliance.  
To change the power cord from one side of insert to the  
other, perform the following steps:  
The ceramic fiber blanket and cerawool strips provided  
with appliance must be placed under the marble to insu-  
late it from the high temperatures on top of the firebox.  
Do not place the marble directly on the top metal surface  
of the stove or it will crack.  
1. Ensure power cord in NOT plugged in.  
2. Remove the louver blower panels on each side of  
fuel door as follows. Each panel is held in place by  
two ¼” (7 mm) head screws. Using a ¼” (7 mm)  
socket or nut driver, remove the screws  
3. Remove panels by pulling them outward slightly then  
forward.  
4. Locate terminal block on right side of appliance.  
Write down the locations where the black, white and  
green leads from the power cord are attached to the  
terminal block. Disconnect these three wires then re-  
install them onto the terminal block on the left side of  
appliance in the same corresponding positions (as  
you had written down).  
5. Reinstall panels.  
BAFFLE PLATE  
This appliance has a very heavy (60 lbs [27 kg]) 3/8" (9.5  
mm) thick steel baffle that is installed directly above the  
secondary air tubes in the firebox. To inhibit the baffle  
plate from shifting during shipment, a packing block is  
installed at the factory (see illustration below). The pack-  
ing block needs to be removed prior to burning your in-  
sert. During installation, the baffle may slide forward, and  
must be repositioned (pushed to the back) in order for  
the insert to operate properly. When in its proper posi-  
tion, the rear flange of the baffle plate should be flush to  
the back wall of the firebox.  
INSTALLATION STEPS  
1.Remove all ashes from the fireplace.  
2.Remove all materials inside the insert and set them aside.  
3.Remove the three-piece surround assembly (face shield)  
and attach insulation material provided using a nonflamma-  
ble adhesive (i.e. RTV Silicone, rated 570° F).  
4.Use a large piece of cardboard or other protective material  
and place it in front of the fireplace to protect floor or carpet  
during installation.  
5.Remove the insert from its wood pallet by removing the  
screws.  
6.Prepare chimney connection system as specified for ma-  
sonry or zero clearance fireplaces.  
7.Set the insert on the protective cardboard laid out in front of  
the fireplace centered in front of the fireplace opening.  
8.(Masonry Fireplace) Slide insert into the fireplace far enough  
to attach the starter pipe or positive flue connection (a mini-  
mum of a 6" (152 mm) starter pipe extending past the  
header is required). See * note, page 11.  
9.(Factory Built Fireplace – USA only) Slide insert into the fire-  
place far enough to attach connector to flue outlet. See *  
note, page 11.  
PAGE 9  
 
INSTALLATION  
10. Offsets can be handled using an offset adapter (it  
aligns starter pipe with flue. See Offset Adapter,  
page 26 for ordering information). Do not push insert  
in completely until surround assembly is installed.  
Care should be used to ensure that this adjustable  
connector is oriented so it does not angle downhill  
when positioned on the flue outlet on top of insert.  
12. Reaching over the top of the insert, install the starter  
pipe in the stove flue, or attach the positive flue con-  
nection to the insert. See * Note, page 11.  
CORRECT  
CORRECT – Level  
or even. Slightly up  
at the outbound  
end is better.  
WRONG  
WRONG – This may  
produce a problem  
of smoking during  
refueling, or poor  
chimney draw.  
11. If the floor of the fireplace is lower than the hearth,  
leveling bolts will need to be installed (not included  
with the hardware. Use a 3/8” (10 mm) bolt with 2  
nuts). The bolt length should be at least 1” (25.4 mm)  
longer than needed. Locate the leveling bolt brackets  
on the sides of the insert in the back. Install the 2  
leveling bolts with nuts and adjust length as needed.

INSTALLATION  
SURROUND ASSEMBLY  
POSITIVE FLUE CONNECTION FOR MASONRY FIREPLACE  
Note: Be sure the damper is locked in the open position.  
IMPORTANT: Do not face seal over chimney  
cooling air system on superior brand or any  
brand fireplace which is designed with the  
chimney cooling air system.  
A Professional should inspect chimney prior to installation to deter-  
mine if any repairs are necessary or if a chimney reline is necessary.  
The fireplace damper must be secured in the open position. If this is  
not possible, it will be necessary to remove the damper. Installation  
into a masonry fireplace requires as a minimum of a flue extension  
past the header. This can be accomplished by one of the following  
methods:  
13. Pull the insert slightly forward to its desired  
position; attach the face shield using the sur-  
round clips and hardware as shown. The fi-  
berglass insulation strips should be secured  
along the top and sides (step 3). Assemble  
the gold-tone trim using the 2 inside corner  
brackets. Attach trim to the face shield and  
stove.  
Install 6" (152 mm) smoke pipe if the chimney is located directly  
above the insert flue outlet.  
(or) Install 6" (152 mm) flex pipe to achieve the same result.  
Push the appliance back until face shield insula-  
tion is compressed against the fireplace front,  
forming a tight seal. Test for air leaks by hold-  
ing a candle around edge of face shield to see  
if smoke is pulled into fireplace.  
*Note: Preferred method of attaching connector  
to flue outlet is to install two L-Brackets (1” [25.4  
mm] angle bracket, 3/4” [19 mm] wide) on oppo-  
site sides of the flue outlet: Use self-tapping  
screws to secure in place. Cut a ½” (13 mm)  
(height) and ¾” (19 mm) (width) notch in the front  
of connector (pipe, liner or adapter that will attach  
to flue outlet). Install connector into flue outlet and  
secure to angle brackets using machine screws.  
Seal around connection with furnace cement.  
Use an offset adapter (see page 26) to handle offsets. This part is  
available through your dealer.

PRODUCT FEATURES AND CONTROLS  
BLOWER SYSTEM  
POSITIVE FLUE CONNECTION FOR MASONRY  
The 500-CFM room air circulation blower system comes  
equipped with a variable speed control (rheostat). The blower  
system can be operated manually or set to operated automati-  
cally (so the blowers will turn on when the insert is hot and turn off  
when the insert is cool). See Care and Operation Section –  
Blower System on page 16.  
FIREPLACE (continued)  
A preferable installation is the positive flue connection  
(a positive seal between the flue extension and the  
chimney). This can be achieved by using a filler plate.  
A filler plate can be made by making a cardboard pat-  
tern to fit the fireplace throat. Lay the pattern on 22  
gage steel, add 2 inches (51 mm) to each side, and  
cut. Snip corners and bend front lip up and sides and  
back down. Cut an opening for the flue. Attach filler  
plate with masonry screws.  
Blower System Controls  
Located on right side of door at bottom of panel.  
Filler Plate  
PRIMARY AIR CONTROL  
The primary combustion air delivery is controlled by the pri-  
mary air control draft module (The control handle is located  
below the fuel door in the center). The heat output can be con-  
trolled by pushing the handle in for a higher burn rate or pulling  
it out for a lower burn rate. The fuel, the amount of heat and  
burn times desired, the type of installation are all variables that  
will affect the control setting. The same control settings in a  
variety of installations will produce different results. You will  
need to try different settings so you can learn how much heat to  
expect and how long the fire will burn.  
The starter pipe extends through the filler plate, past  
the damper and into the existing chimney system.  
Small air leaks should be sealed with high temp fiber-  
glass or ceramic insulation.  
START-UP AIR CONTROL  
The start-up air control provides additional air delivery to assist in  
establishing a draft in a cold flue system (The control handle is  
located below the fuel door on the left). From a cold start, ap-  
proximately 10 minutes in the open position is all that is required  
to achieve a stable burn.  
PAGE 12  
 
CARE AND OPERATION  
GLASS  
GOLD DOOR  
The glass is a super heat resistant ceramic that with-  
stands continuous temperatures up to 1390° F. This tem-  
perature is well beyond the temperatures in which you  
operate your fireplace insert.  
The doorframe is plated with 24-karat industrial grade gold  
and requires curing to harden the gold. Once it is cured it  
will never tarnish. Prior to burning this appliance the door-  
frame should be cleaned thoroughly with a good window  
cleaning solution and a soft cloth. Do not use any metal  
polishes or abrasives to clean the gold surface. Any oils or  
fingerprints left on the gold could become permanent  
blemishes if the stove is burned prior to their removal. Af-  
ter the first few fires, the gold will cure. The ¾” (19 mm)  
diameter door rope gasket is made of highly durable high  
temperature resistant material. It must be kept in good  
condition. Do not leave the stove burning with the door  
ajar or open. Leaving the door ajar or open while the stove  
is burning will cause excessive heat build up in the stove  
(overfiring) and could ignite surrounding combustibles as  
well as damage the stove (such damage is not covered by  
the manufacturer's warranty).  
This appliance is designed to provide a flow of air over the  
inside of the glass, where along with high heat helps keep  
it clean. When operating the fireplace insert on low for  
extended periods of time, the glass may get dirty. A short,  
hot fire (15 - 20 minutes) will help clean off much of the  
normal buildup (see Troubleshooting, pages 19-20). A  
commercial glass cleaner designed for fireplace inserts is  
recommended for cleaning.  
The glass should be cleaned thoroughly with glass  
cleaner and a soft cloth BEFORE the fireplace insert  
is burned.  
DOOR GASKET  
The door gasket must be kept in good condition. Do not  
leave the stove burning with the door ajar or open. Leav-  
ing the door ajar or open while the stove is burning will  
cause excessive heat build up in the stove (overfiring) and  
could ignite surrounding combustibles as well as damage  
the stove (such damage is not covered by the manufac-  
turer's warranty).  
DOOR OPERATION  
CAUTION: WHEN OPENING THE DOOR, DO NOT EX-  
TEND IT BEYOND ITS NORMAL TRAVEL. OVEREX-  
TENDING THE DOOR TO A FURTHER OPEN POSI-  
TION CAN PUT EXCESSIVE STRESS ON HINGE AREA  
OF DOOR AND HINGE PINS AND MAY RESULT IN  
BREAKAGE.  
BREAK-IN PERIOD  
Your fireplace insert finish is a high temperature paint that  
requires time and temperature to completely cure. We rec-  
ommend that you ventilate the house during the initial  
burns. The paint emits non-toxic odors during this process.  
The door handle assembly is used to open and close the  
fuel door assembly as follows:  
KEEP YOUR HOUSE WELL VENTILATED DURING THE  
CURING PROCESS TO PREVENT ACTIVATION OF  
YOUR HOME SMOKE DETECTOR.  
To open the fuel door - Rotate the coil handle from the  
6:00 position toward the 9:00 position, until door releases  
(see illustration below).  
The paint manufacturer recommends three burn cycles to  
cure the paint. The first two burns should be low heat, ap-  
proximately 250°F., for 20 minutes each, using paper and  
light kindling.  
To close the fuel door - Push door closed with the han-  
dle positioned in the 9:00 position. While pressing in, ro-  
tate the handle to the 6:00 position.  
After each 20-minute burn, allow the appliance to cool com-  
pletely. The third burn should be at least medium high or  
about 450°F. for 45 - 60 minutes. The paint will become soft  
and emit non-toxic haze during these burns. Keep the area  
well ventilated.  
As the paint cures it will become slightly lighter in color.  
Eventually the entire surface will become an even color.  
Once the paint has been softened and cooled two or three  
times, it will harden. Do not turn on a blower during the  
curing process.  
Do not place anything on the fireplace insert surface until  
the paint is completely cured. Do not attempt to repaint  
the fireplace insert until the paint is completely cured. If  
the surface later becomes stained or marred, it may be  
lightly sanded and touched up with spray paint from the  
same paint manufacturer (See Maintenance – Small Area  
Paint Touch-up, page 16). Paint is available at your local  
authorized Lennox Hearth Products dealer. Never attempt  
to paint a hot stove.

CARE AND OPERATION  
AIR DRAFT CONTROLS  
HOW TO START AND MAINTAIN A FIRE  
1. Set the primary air control to the open position (push  
in).  
2. Set the start-up air control to the open position (pull  
out).  
This appliance has two combustion air controls located  
under the hearth extension. The control on the left is the  
Start-Up Air Control. The control in the center is the Pri-  
mary Air Control.  
3. Build a fire directly on the firebrick covering the bot-  
tom of the stove.  
a. Place two or three loosely crumpled sheets of  
newspaper in the insert firebox.  
b. Add a small amount of dry kindling randomly on  
the top of the newspaper.  
c. Place one or two more loosely crumpled newspa-  
pers on top of the kindling and light the bottom  
paper first, then light the top paper.  
4. Once the kindling is ignited and burning on its own,  
close the fuel door. The upper fire should help pre-  
heat the chimney and create an effective draft while  
the lower fire ignites the kindling.  
5. When the kindling is burning well, add increasingly  
larger pieces of wood until the fire is actively burning  
and a coal bed develops. By keeping both air con-  
trols open for approximately 10 minutes, the fuel and  
the insert will quickly come up to ideal operating tem-  
peratures producing the highest combustion effi-  
ciency and least emissions.  
Start-Up Air Control  
To provide sufficient combustion air to achieve a clean  
burn as quickly as possible, the 2800HT supplements its  
primary air with a separate "Start-Up" supply. This con-  
trol should be used only when starting a fire or when  
refueling. The start up air enters the stove at the rear of  
the firebox and is controlled by the Start-Up Air Control  
rod on the left.  
6. Close the start-up air control (push in).  
CAUTION: THIS CONTROL SHOULD ONLY BE  
USED DURING START UP AND REFUELING.  
7. Set the primary air control to the desired setting. The  
insert will now provide clean, efficient and safe heat  
for your home.  
From a cold start, approximately 10 minutes in the open  
position is all that is required to achieve a stable burn.  
CAUTION: OPERATION OF THE APPLIANCE WITH  
THE START-UP AIR CONTROL IN THE "OPEN" POSI-  
TION (PULLED OUT) FOR EXTENDED PERIODS,  
WASTES FUEL AND CAN CAUSE DANGEROUS  
OVERFIRING CONDITIONS.  
REFUELING  
To refuel the insert, first move the primary air control to  
high. Let the fire "liven up" for about one minute. Open  
the fuel door about 1/2" (1 cm) and hold in this position  
about 30 seconds or until insert is drafting well. Open  
the door and add wood. If the fire or coal bed is almost  
depleted and a full load of cordwood is added, it may be  
necessary to open the start-up air control to re-establish  
a lively fire. The use of start-up air should only be used  
for a short period.  
PRIMARY AIR CONTROL  
Once the fuel load is well ignited, the Primary Air Control is  
all that is needed to vary the burn rate in the insert. Push in  
for a high burn rate; pull out for a slower burn rate.  
NOTE: After refueling and the wood is burning at a  
brisk rate, reset the primary air control to the desired  
position and close the start-up air control.  
USE CONTROL SETTINGS THAT WORK FOR YOU  
The fuel, the amount of heat you want, the type of instal-  
lation you have and how long you wish the fire to burn  
are all variables that will affect the control setting. The  
same control settings in a variety of installations will pro-  
duce different results.  
Familiarize yourself with your fireplace insert by trying  
different settings so you can learn how much heat to  
expect and how long the fire will burn. It may take a  
week or two to learn but your patience will be rewarded  
by the warmth and pleasant satisfaction that only a  
wood fire can provide.

CARE AND OPERATION  
WIRING DIAGRAM  
BLOWER SYSTEM  
The Blower System consists of a ON / OFF  
rocker switch, a variable speed blower speed  
control switch (rheostat) located on the right  
side panel, a thermally activated switch (fan  
disc) and 4 axial blowers.  
When starting a fire, leave the blower system  
off until the insert is thoroughly heated (approx.  
30 minutes after start up).  
The blowers can be operated in one of the fol-  
lowing manners:  
Auto: Turn rocker switch to the off position (  
O” = off, ““ = on). Turn the rheostat to the on  
position by rotating the rheostat dial clockwise  
until it clicks. When the insert warms up (110°  
F), the blower will automatically turn on (adjust  
rheostat dial to the desired speed setting).  
When the insert cools down (90° F), the blow-  
ers will automatically turn off.  
POWER FLOW DIAGRAM  
Manual: Turn rocker switch to the on ( )  
position and adjust rheostat dial to the desired  
speed. The blowers will have to be manually  
turned off by rotating the rheostat dial counter-  
clockwise until it clicks.  
BLOWER SPECIFICATIONS: 115 V, 60 Hz,  
two axial blowers - .42 amps each, 125 CFM  
each. Blower system has a flexible electrical  
cord that must be electrically grounded per lo-  
cal codes or NEC, ANSI / NFPA 70-latest edi-  
tion. Do not route the power cord under or in  
front of the appliance.  
CAUTION: BURNING THE INSERT AT A HIGH BURN RATE  
FOR EXTENDED PERIODS WITHOUT RUNNING THE BLOW-  
ERS CAN CAUSE EXCESSIVE TEMPERATURES RESULTING  
IN OVERFIRING DAMAGE TO THE APPLIANCE. EXCESSIVE  
HEAT WILL CAUSE THE PROPELLERS ON THE BLOWERS TO  
MELT. IF THIS OCCURS, REPLACE PROPELLERS AND RE-  
VIEW THESE INSTRUCTIONS FOR PROPER OPERATION  
(PROPELLER PART / CATALOG #410-25-3. SOME PEOPLE  
PREFER METAL PROPELLERS, WHICH ARE AVAILABLE

FUEL  
MAINTENANCE  
SEASONING GUIDE  
Softwoods – 6 months to 18 months  
Hardwoods – 12 months to 24 months  
BURN RECOMMENDED FUEL  
This appliance is approved for use with wood only. Use  
only natural dry untreated wood (see Important Warn-  
ings, page 2, #10). Do not burn particleboard scraps or  
pressed logs using bonding agents because they can  
produce conditions which will deteriorate metal. Green or  
uncured wood does not work well as fuel, and can cause  
increased creosote buildups. The value of green wood as  
a source of heat is limited. Do not overload or use kin-  
dling wood or mill ends as primary fuel as this may cause  
overfiring. Overfiring is a condition where excessive tem-  
peratures are reached, beyond the design capabilities of  
the stove. The damage that occurs from overfiring is not  
covered under the stove warranty.  
Logs that are 5” (127 mm) diameter across or larger should  
be split in half, three pieces if over 8 inches (203 mm), and  
four pieces when over a foot across. If the tree fell 2 to 4  
years ago, it still needs to be cut, split, and seasoned for 6  
to 24 months depending on the wood.  
WOOD STORAGE  
Wood to be seasoned should be stacked in an area open  
enough to ensure good air circulation on both sides – leav-  
ing adequate space between woodpiles to walk comfort-  
able. Do not stack wood against a wall or building.  
It helps to elevate the woodpiles off the ground (two 2 x 4’s  
running lengthwise beneath the woodpile works well). This  
allows air to flow under the bottom logs. Wood that is kept  
outdoors, either covered with a tarp, or not covered at all,  
will not burn well until it has been in an enclose space for  
one to two months.  
WARNING: BURNING IMPROPER FUEL (I.E. CHAR-  
COAL) CAN RESULT IN CARBON MONOXIDE POI-  
SONING WHICH MAY LEAD TO DEATH!

ARE MORE AFFECTED BY CARBON MONOXIDE  
The stove body is painted with a quality high-temperature  
stove paint. Use only model TSPK-B Stove Paint, Cata-  
log # 70K99. Do not touch-up your stove with any other  
paint.  
Using one small piece of 320 grit sand paper and lightly  
sand the blemish so that the edges are “feathered” or  
smooth to the touch between the painted and bare sur-  
faces. Do not let the sand paper gum up with paint, as  
this will cause scratches on the metal surface. If there  
are any scratches, use 600 grit sandpaper instead. Mask  
off surfaces you do not want painted. Paint lightly over  
the bare surface first as this will act as an undercoat.  
Then paint over a larger area in smooth even strokes to  
blend. See Break-In Period on page 13 for information on  
curing the paint.

WHY SEASONED WOOD?  
The key to the success of a good fire that produces heat  
from a wood burning insert is the wood. It needs to be well-  
seasoned natural wood.  
FIREBRICK  
The firebrick should be inspected periodically and re-  
placed if damaged (crumbling or excessively cracked).  
ASH REMOVAL AND DISPOSAL  
What does “Well-Seasoned” mean?  
CAUTION: MAKE SURE THAT THE FIRE IS OUT AND  
THE STOVE IS COLD BEFORE REMOVING ASHES!  
When a tree is cut down, the wood is green, full of sap and  
moisture. This moisture content can exceed 80%, which  
must be reduced to less than 20%. Wood properly sea-  
soned is then capable of generating the heat the fireplace  
insert was designed to provide.  
Ashes can hold live embers for several days, and must  
be disposed of with care.  
NEVER place ashes in a cardboard box or any other  
combustible receptacle.  
Proper Disposal of Ashes:  
Green wood does not burn easily. Attempting to burn green  
wood often results in a lot of smoke and very little fire. Time  
is the most important factor in seasoning wood. Ideally the  
moisture content should be reduced to 11-20%, although  
very few of us will be able to check that figure. There are  
several steps that should be taken to ensure that that you  
come close to these figures.  
Ashes should be placed in a metal container with a tight  
fitting lid. The closed container of ashes should be  
placed on a noncombustible floor or on the ground, well  
away from all combustible materials, pending final dis-  
posal. If the ashes are disposed of by burial in soil or  
other wise locally dispersed, they should be retained in  
the closed container until all cinders have thoroughly  
cooled.

MAINTENANCE  
DOOR GASKET  
CLEANING BLOWERS  
A spun fiberglass gasket (3/4" [19 mm] in diameter) pro-  
vides the seal around the fuel door. Should this become  
frayed or damaged it should be replaced. Spun fiberglass  
"rope" gasketing can be purchased from your dealer. It  
must be the same diameter as the original. Use high  
temperature silicone sealer as an adhesive, which can  
also be purchased from your dealer.  
The blowers require inspection and cleaning annually to  
remove lint, dust, etc. If there are pets in the dwelling, the  
blowers should be cleaned at least twice a year To ac-  
cess, remove blower covers (remove the two ¼” [7 mm]  
hex head screws on each panel), then inspect propellers  
(replace if cracked, broken or melted) and vacuum out  
lint, dust, and debris.  
WARNING! THE GASKETS MUST BE KEPT IN GOOD  
CONDITION. DO NOT LEAVE THE STOVE BURNING  
WITH THE DOOR OPEN OR AJAR (OTHER THAN  
START UP AND REFUELING AS DEFINED IN THIS  
MANUAL). THIS WILL CAUSE EXCESSIVE HEAT  
BUILD UP IN THE APPLIANCE AND COULD IGNITE  
SURROUNDING COMBUSTIBLES AS WELL AS DAM-  
AGE THE STOVE BY OVERFIRING IT. OVERFIRING  
IS A CONDITION WHERE EXCESSIVE TEMPERA-  
TURES ARE REACHED, BEYOND THE DESIGN CA-  
PABILITIES OF THE STOVE (SUCH DAMAGE IS NOT  
COVERED BY THE MANUFACTURER'S WARRANTY).  
CREOSOTE FORMATION AND NEED FOR REMOVAL  
What is Creosote - When wood is burned slowly, it pro-  
duces tar and other organic vapors, which combine with  
expelled moisture to form creosote. The creosote vapors  
condense in the relatively cool chimney flue of a slow-  
burning fire. As a result, creosote residue accumulates  
on the flue lining. When ignited this creosote makes an  
extremely hot fire. Also, creosote deposits tend to form in  
long runs of venting where gases become too cool prior  
to exhausting. Note: Single wall pipe cools rapidly, there-  
fore installations using this type of flue are more suscep-  
tible to creosote deposits.  
SERVICING GLASS  
To inhibit the build up of creosote, adjust the primary air  
control to a medium-high or high setting for a 10-minute  
period each day. Do not attempt to burn out heavy creo-  
sote accumulations in this manner. This must be re-  
moved from the chimney by scraping or brushing to re-  
duce the risk of a chimney fire.  
CAUTION: BE CAREFUL NOT TO ABUSE DOOR AS-  
SEMBLY BY STRIKING OR SLAMMING IT. IF THE  
DOOR ASSEMBLY OR GLASS IS BROKEN OR DAM-  
AGED, THEY MUST BE REPLACED BEFORE  
HEATER CAN BE SAFELY OPERATED. USE ONLY  
COMPONENTS PROVIDED BY THE MANUFAC-  
TURER AS REPLACEMENT PARTS.  
Burn Approved Fuel Only - This stove is approved for  
burning dry seasoned natural wood only. Using green or  
inadequately seasoned wood may increase creosote  
buildup.  
Cleaning Glass: Ensure stove is cold prior to cleaning  
glass. A commercial glass cleaner designed for stoves is  
recommended. Do not use abrasive cleaners.  
Replacing Glass:  
Removal of Fireplace Insert for Inspection:  
1. Remove door from stove by lifting door up and off  
hinge pins: Place the door on a flat protected (towel)  
clean flat surface with the inside of the door facing up.  
Remove the glass clips (by removing screws holding  
clips), then carefully remove broken glass one piece  
at a time (protective gloves are recommended).  
2. Clean area where the glass with gasket will be in-  
stalled.  
3. Install new glass with gasket (use only factory 5-mm  
glass with glass channel gasket. Do not substitute).  
Carefully reinstall glass clips. Be very careful not to  
overtighten screws.  
Pull Fireplace insert forward until the screws securing the  
flue connection can be accessed. Detach flue by remov-  
ing screws. Pull unit forward and out of fireplace. Inspect  
the chimney and chimney connector as follows:  
Inspection Frequency - The chimney connector and  
chimney should be inspected at least twice monthly dur-  
ing the heating season to determine if a creosote buildup  
has occurred. If creosote has accumulated it should be  
removed to reduce the risk of a chimney fire.  
4. Reinstall door.  
To reinstall insert follow instructions on pages 9 and 10  
(instructions # 8 through 12).  
PAGE 17  
 
MAINTENANCE  
Cleaning – If the chimney is to be cleaned without re-  
moving the insert from the fireplace, the baffle plate (in  
the firebox) must first be removed. Chimney cleaning  
should only be done by a qualified chimney sweep. See  
following – Cleaning / Removing Baffle Plate.  
In the event of a chimney fire - Make sure the fuel door  
is securely closed. Adjust the primary air control to the  
lowest (most closed) setting. Call the fire department  
immediately. After a chimney fire, the complete chimney  
system should be checked by a qualified technician be-  
fore further use.  
Cleaning / Removing Baffle Plate - To remove, locate  
the 3 secondary air tubes, which support the baffle in the  
upper firebox. They are secured in place by one bolt  
each at the point where they meet the left wall. Remove  
bolt and slide tube to the right until it releases. Remove  
all 3 tubes this way. Next slide the baffle plate all the way  
to one side until it will drop diagonally into lower firebox.  
Remove baffle plate through door opening (diagonally).  
Consult your dealer for suggestions on proper chimney  
care. Contact your local municipal or provincial fire au-  
thority for information on how to handle a chimney fire.  
Have a clearly understood plan for handling a chimney  
fire.  
REINSTALL BAFFLE PLATE  
After your chimney has been swept, reinstall the baffle  
plate. See – Cleaning / Removing Baffle Plate above and  
reverse steps.  
WARNING! DO NOT OPERATE THE INSERT WITH-  
OUT THE BAFFLE PLATE PROPERLY INSTALLED.  
THIS WILL VOID WARRANTY  
PAGE 18  
 
TROUBLESHOOTING  
* SMOKES OUT FUEL DOOR WHEN OPEN  
1. The primary air control is closed.  
2. The chimney is too cool. Set the primary air control  
on HIGH setting with start-up control OPEN for a few  
minutes before opening the fuel door.  
3. Excess creosote will not only restrict your draft but it  
will create a risk of a creosote fire. Strictly adhere to  
maintenance requirements as outlined in this man-  
ual. If excess creosote has built up on the inside of  
the firebox sides and door, burn a small hot fire at in-  
tervals that are more frequent with start-up control  
open and primary air control on high for a few min-  
utes.  
* DOES NOT MAINTAIN A FIRE  
1. Soft wood does not burn as long or as well as sea-  
soned hardwood resulting in a short burn time.  
2. Wood size too small. Burns at too rapid a rate.  
3. The gasket seal on the fuel door or glass is leaking  
air. Repair or replace it if necessary.  
4. Excessive Draft.  
5. There may be an obstruction in the chimney.  
* BACKPUFFING  
1. Downdraft in the chimney (a special wind cap may  
be needed).  
2. The house is too airtight (ventilation is needed).  
3. Insufficient vertical height to chimney to achieve  
adequate draft.  
4. Deposits may have built up in the chimney and are  
restricting the draft, or the spark arrester on top of  
the chimney may be plugged.  
5. Chimney diameter too large or too small to provide  
adequate draft.  
6. The house is too airtight (usually takes 20 to 30 min-  
utes for problem to appear as stove lowers air pres-  
sure in house). Crack a window open or provide an  
outside source of air near insert.  
ODORS  
1. Creosote accumulation in firebox (brush out on next  
cleaning).  
2. Chimney downdraft when stove is not operating  
(close the primary air control).  
3. Paint curing on first several burns.  
7. Insufficient vertical height to chimney to achieve  
adequate draft.  
* DIRTY GLASS  
DOES NOT PRODUCE ENOUGH HEAT  
1. Using green or insufficiently cured wood.  
2. Excessive draft.  
3. High ceilings (heat rises quickly, but can be recircu-  
lated by a well-placed ceiling fan with a winter /  
summer switch).  
4. The area to heat is too large (square foot heating  
estimates are based on "average" climates and  
home design.)  
5. There is an obstruction in the chimney.  
6. The chimney or chimney cap is restricted by creo-  
sote preventing enough draw to sustain a "high" heat  
output rate.  
1. Poor draft conditions.  
2. Long burn periods at low draft settings.  
3. Burning wet, pitchy or spongy wood.  
4. Poorly arranged logs (too close to glass).  
*
Draft problems -- If installing into a larger flue, it  
may be necessary to use a full-length liner to  
achieve adequate draft for the appliance. A draft  
gauge should read a minimum of .05" w.c.  
(inches water column) not to exceed .07" w.c.  
for optimum performance (See Draft Require-  
ments, page 5).

TROUBLESHOOTING  
OVERFIRING DAMAGE  
Overfiring Caused From Improper Operation - Operate  
this appliance only as outlined in this manual. Never burn  
the appliance with the fuel door open or ajar. Do not oper-  
ate this stove with the primary air control in the "high" posi-  
tion (pushed in) for extended periods. This wastes fuel  
and can cause dangerous overfiring conditions. NEVER  
leave the stove unattended on high settings. Operation of  
the appliance with the Start-Up Air Control in the open  
(pulled out) position for extended periods can cause  
dangerous overfiring conditions.  
If the heater or chimney connector glows, you are overfir-  
ing. Other symptoms may include: Cracking, warping or  
burning out of components, gold door may turn color, stove  
glass may develop a haze, which will not come off with  
cleaning.  
Overfiring of a stove is a condition where excessive tem-  
peratures are reached, beyond the design capabilities of  
the appliance. The damage that occurs from overfiring is  
not covered under the MANUFACTURER'S limited war-  
ranty.  
Overfiring Caused from Improper Maintenance -  
Strictly adhere to all maintenance requirements at fre-  
quent intervals as prescribed in this manual including  
cleaning of flue and stove. Should the fuel door or glass  
gaskets become worn or damaged, they should be re-  
placed.  
The following are a few conditions that should be evalu-  
ated (and corrected, if necessary) if an overfiring condi-  
tion is suspected:  
Overfiring Caused From Improper Installation - Ensure  
that all installation requirements have been met as out-  
lined in the installation manual. The chimney should be  
clean and in good repair. A draft test should be performed  
to determine if the draft requirements of the appliance are  
being met. A draft gauge should read between .05 and .07  
inches water column (" W.C.). Excessive draft (above .07  
" W.C.) will allow too much combustion air to be pulled in  
which results in hotter burns. Too little draft (below .05 "  
W.C.) will not allow enough combustion air delivery to  
maintain a fire (this may result in improper operation of  
appliance, i.e. wont maintain fire unless fuel door is left  
open. See below, Overfiring Caused From Improper Op-  
eration on this page.  
Overfiring Caused From Improper Fuel - This appliance  
is approved for use with natural dry well seasoned wood  
only (ask your authorized dealer what are approved fuels  
for your area). Do not burn garbage, particleboard scraps,  
or pressed logs using bonding agents because they can  
produce conditions that will deteriorate metal. Do not over-  
load or use kindling wood or mill ends as primary fuel as  
this may cause overfiring.
