ORIFICE SIZE/ALTITUDE ADJUSTMENT  
THE GAS STOVE  
For altitudes above 2,000 feet (In Canada 4,500 FT/1370 M),the orifice  
should be de-rated by 4% for every 1,000 feet to maintain the proper  
ratio of gas to air. Improper orifice sizing may result in damage and  
unsafe conditions. Changing the orifice should only be done by a quali-  
fied service technician. Contact your Lennox Hearth Products dealer for  
proper orifice sizes.  
• Must conform with all local, state and national installation codes. In  
theabsenceoflocalcodes, theinstallationmustconformwithNational  
Fuel Gas Code ANSI Z223.1 - latest edition, also known as NFPA 54  
(In Canada, the current CAN/CSA B149.1 installation code). Refer to  
the National Fuel Gas Code and local zoning and code authorities for  
details on installation requirements.

tion.  
SMOKE DETECTORS  
Since there are always several potential sources of fire in any home, we  
recommend installing smoke detectors. If possible, install the smoke  
detector in a hallway adjacent to the room (to reduce the possibility of  
occasional false activation from the heat produced by the appliance). 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.  
• Must be vented directly to the outside in accordance with the latest  
edition of the National Fuel Gas Code and must never be attached to  
a chimney serving a separate solid fuel burning appliance.  
• Has been certified for use with either natural gas or propane.

ent log set in the fireplace will void the warranty and will result  
in incomplete combustion, sooting and poor flame quality.  
Parts list: rear log, left front log, right front log and straight twig  
1) Remove the logs from the box and carefully unwrap them. The logs  
are fragile so handle them with care.  
2) Align the holes in the bottom of the rear log (the longest log in the set)  
with the two pegs just to the rear of the rear burner tube and slide the  
log down onto the pegs (Figure 10). The charred black surface of the  
log should face the front.  
3) The left front log has two pegs protruding from the top surface (Fig-  
ure 11). The charred black with white highlights surface of the log  
should be facing forward. Slide this log down onto the left front and  
center front pegs.  
4) The right front log (positioned with the black charred surface towards  
the front) should be placed on the peg protruding from the right end  
of the left front log and the remaining peg at the right end of the metal  
log support panel (Figure 11).  
Figure 12  
Note the location of the hole for viewing the  
pilot light. When the pilot is burning, a  
blue flame can be seen through  
this hole.  
5) The remaining straight twig has two holes in the bottom. Position the  
twig so the black and white charring is to the front and slide the holes  
over the peg in the left front log and the peg in the rear log (Figure  
12). It may be necessary to roll the top of the rear log slightly forward  
to put this twig on the pegs.  
6) Figure 13 shows the entire log set assembled. The embers provided  
may be placed one high in front of the front burner tube using care not  
to cover all the burner ports. Any extra embers may be placed at the  
ends of the front log, off the burner. Place small pinches of rockwool  
on top of the embers.

1 Decorative Wall Trim (black)  
Important:  
• 1 Tube Mill-Pac  
• Screws  
• Read all instructions carefully before starting the installation.  
Failure to follow these instructions may create a fire or other  
safety hazard and will void the warranty. Be sure to check for  
specific clearances to combustible requirements on Page 9.  
Do not extend the venting system vertically or horizontally in  
excess of the distance prescribed on Page 16. Consult your  
local building codes before beginning the installation.  
Always maintain the proper air spaces between the vent pipe  
and nearby combustibles to prevent a fire hazard. Do not fill  
air spaces with insulation. Be sure to check the vent termina-  
tion clearance requirements from decks, windows, soffits, gas  
regulators, air supply inlets and public walkways, as specified  
in these installation instructions on Page 17 and local building  
codes.  
This gas appliance and vent system must be vented directly  
to the outside of the building and never be attached to a  
chimney serving a separate solid fuel or gas-burning appli-  
ance. Eachdirect-ventgasappliancemustuseitsownseparate  
vent system. Common vent systems are prohibited.  
• This appliance is recommended for use with Security™ Secure  
Vent pipe*. The appliances and vent manufacturers warranties

Vent Considerations:  
Twist-lock procedure: Four indentations on female ends of pipes and  
fittings are designed to slide straight onto male ends of adjacent pipes  
and fittings by orienting the four pipe indentations so they match and  
slide into the four entry slots. Push pipe sections completely together,  
then twist-lock one section clockwise approximately one-quarter turn  
until the two sections are fully locked. The female locking lugs will not  
be visible from the outside on the pipe or fittings. They may be located  
by examining the inside of the female ends.  
Supports: Horizontal runs of vent must be supported every 3 feet. Wall  
straps are available for this purpose.  
- Installation of any damaged direct-vent component.  
- Unauthorized modification of the direct-vent system.  
- Installation of any vent component part not approved or  
manufactured by the approved vent manufacturer.  
- Installation other than as instructed by Lennox Hearth  
Products and vent manufacturers instructions.  
PipeSealing: IfSimpsonDura-Ventpipeisused,thepipemustbesealed  
as follows: seal both the inner and outer pipes with a high temperature  
silicone sealant rated for at least 600ºF (commonly know as “RTV”). Run  
a 1/8” bead of silicone around outside of male end of outer sleeve. Run  
a 1/8” bead of silicone about 1/4” from the end of the male inner pipe,  
which is found in the pipe to be attached above. Twist-lock the pipes or  
fittings together.

Vent Parts List  
Horizontal Vent Installation  
Secure Vent direct-vent pipe by Security Chimneys* may be used with  
this appliance. Please see the lists below to verify the components avail-  
able from each direct-vent pipe manufacturer. Snorkel terminations are  
available for applications which may require vertical rise on the building  
exterior. The components listed below come in a galvanized finish. Most  
of the components are also available in a painted black finish. Add a “B”  
to the end of the part number when ordering if a black part is desired.  
Venting terminals may not be recessed into a wall or siding.  
1. Set the unit in the desired location. Check whether or not wall studs  
are in the way when the venting system is attached. If wall studs are  
in the way, you may want to adjust the location of the unit.  
2. Any stove that is horizontally terminated and has a vertical section  
of pipe off the top of the stove, that first section of pipe must be a  
minimum of 18” long.  
3. All horizontally terminated vent installations may only use 6-5/8”x 4”  
Security™ Secure Vent pipe*.  
4. Assemble the desired combination of pipe and elbow(s) to the appli-  
ance adapter with pipe seams facing down. Offsetting the pipe seams  
as double seams in one place will cause the outer pipe to take an oval  
shape.  
5. When this pipe passes through a wall, a wall thimble - Simpson #942  
or Security™ #SV4RSM - is required. The hole in the wall for the  
wall thimble should be 9-1/4”x 10-1/4”. If the wall being penetrated  
is constructed of non-combustible material (i.e. masonry block or  
concrete), a 7” diameter hole is acceptable and a wall thimble is not  
required.  
6. Horizontal runs of vent pipe must be supported every 3 feet. Wall  
straps - Simpson #988 or Security™ #SV4BM - are available for this  
purpose.

Snorkel Terminations  
For installations requiring a vertical rise on the exterior of the building,  
14-inch and 36-inch tall snorkel terminations are available. When us-  
ing a snorkel, the stove can be vented directly out the back. There is a  
vent starter collar fastened to the stove (to vent straight out the back),  
remove the four screws securing the collar, rotate the collar 180 degrees  
and refasten using the same four screws. Make sure the gasket between  
the collar and the stove is properly positioned before refastening the  
collar. After rotating the collar, it will be positioned horizontally. When  
this pipe passes through a wall, a wall thimble - Simpson part number  
942or Security™ part number SV4RSM is required. The hole in the wall  
for the wall thimble should be 9-1/4” wide by 10-1/4” high. To vent out  
the rear wall, add up to a 12” section of pipe and then the snorkel. When  
the stove is located in a corner of the room, to vent horizontally first  
add a 45 degree elbow, then up to a 12” section of pipe and lastly the  
snorkel. Installations using a snorkel have no restrictor installed in the  
pipe (see Pages 15 and 16 for restrictor positioning). Follow the same  
installation procedures as used for standard horizontal terminations. If  
the snorkel termination must be installed below grade, (i. e. basement  
application), proper drainage must be provided to prevent water from  
entering the snorkel. Do not attempt to enclose the snorkel within the  
wall, or any other type of enclosure. On vinyl siding, furring strips may  
be used to ensure that the snorkel is not recessed into the siding.

Flue Restrictors  
4 3 2 1  
The flue restrictor settings shown in Figures 26 and 27 are for typical  
installations and may need to be adjusted from standard to take into  
accountothervariablesintheinstallationtoachievepropercombustion.  
See Flue Restrictor Guidelines on this page to assist you in making a  
proper flue restrictor adjustment.  
This appliance uses balanced flue technology to ensure proper combus-  
tion. A flue restrictor may need to be installed depending on the vent  
configuration of your stove. The drawings on Page 16 show all the al-  
lowable pipe configurations for this appliance. To properly install the flue  
restrictor, find your pipe configuration in the drawings on Page 16 and  
note which restrictor setting is recommended. The flue restrictor and two  
black self-tapping 5/32” allen head screws can be found in the firebox  
in a plastic bag. The restrictor should be placed over the flue opening  
on the ceiling of the firebox. On the restrictor, two self-tapping 5/32”  
allen head screws should be installed in either holes 1, 2, 3, or 4 in the  
restrictor and screwed into the two holes in the firebox ceiling. See the  
drawing to the right for the location of hole numbers on the restrictor. The  
numbered holes in which the screws are inserted in the restrictor should  
correspond to the restrictor position numbers found on the drawings for  
your pipe configuration. Restrictor positions are based on tests run in  
a laboratory. The optimum restrictor positions may need to be adjusted  
slightly depending on the conditions surrounding the residential instal-  
lation. Do not adjust restrictors to a point where the fireplace is sooting.  
Restrictor  
Figure 23  
Notes: The higher the number of the flue restrictor position, the greater  
amount of combustion air will be delivered.

top of the firebox  
Flue Restrictor Adjustment Guidelines  
A
After the flue restrictors have been set to the standard settings as shown  
in Figures 26 and 27 on Page 16, the burner flame appearance should be  
evaluated to determined if the flue restrictors need to be set to a different  
position to adjust for variables in your installation. Light the appliance  
and allow it to burn for 20 minutes. See Flame Color and Behavior on  
Page 21 to determine if you have a proper burner flame appearance. If  
the proper flame appearance cannot be achieved, the flue restrictor may  
need to be set to a different position. See the following guidelines to  
determine if you need to readjust the flue restrictors.

Horizontal Terminations  
Vertical Terminations  
The shaded areas in the diagram below show all allowable combinations  
of vent configurations with horizontal terminations. Horizontal sections  
of pipe require 1/4” of rise for every 12” of run. A second 90 degree or  
45 degree elbow (in addition to the first 90 degree elbow at the top of  
the vertical length of pipe) is allowed as long as the overall length of  
the horizontal run of pipe does not exceed those shown below. Use the  
restrictor positions indicated. Note that if the termination cap falls in the  
unshaded area below then no restrictor is installed in the stove.  
The diagram below shows all allowable combinations of straight verti-  
cal and offset to vertical vent configurations with vertical terminations.  
The termination must fall within the shaded areas on the diagram. Use  
the indicated restrictor positions. Offsets may consist of two 90 degree  
elbows OR four 45 degree elbows. The minimum termination height is  
10’ and the maximum is 30 feet.  
To install the stove with pipe directly out the back (as shown in Figure  
21 on Page 14), a snorkel is required for this appliance. See Page 14 for  
snorkel installation instructions.

If the pressure is not sufficient, make sure the gas supply line is large  
enough, The supply regulator is properly adjusted and the total gas load  
for the residence does not exceed the amount supplied.  
Gas Line Installation  
This stove must be connected to the gas line in accordance with local  
codes and/or the National Fuel Gas Code, ANSI Z223.1 (In Canada, the  
current CAN/CSA B149.1 installation code).  
Propane tanks are at pressures that will cause damage to valve com-  
ponents. Verify that the tanks have step down regulators to reduce the  
pressure to safe levels.  
The gas line screws into the gas valve at the back of the stove 5” in from  
the right side of the stove and 4 3/16” up from the base of the unit. After  
connecting the gas line, all joints in the line and connections at the valve  
should be checked for leaks. After connecting the gas line, all joints in  
the line and connections at the valve should be checked for leaks before  
final positioning of the unit. Conduct a gas leakage test of the appliance  
piping and control system downstream of the shutoff valve in the supply  
line to the appliance.  
The appliance must be isolated from the gas supply piping system  
by closing its equipment shutoff valve during any pressure testing of  
the gas supply piping system at test pressures equal to or less than  
1/2 psig (3.5 kPa).  
The appliance and its appliance main gas valve must be disconnected  
from the gas supply piping system during any pressure testing of that  
system at test pressures in excess of 1/2 psig (3.5 kPa).

Flame Color and Behavior  
3. Push in gas control knob slightly and turn clockwise  
to “OFF.” Do not force.  
This appliance is designed for maximum heating efficiency. Therefore,  
upon lighting of the main burner the flames will be semi-transparent or  
“bluish.” After 10-20 minutes of operation the logs will heat up and the  
flames will become a yellow/orange color.  
SHUTDOWN PROCEDURE  
To turn off the burner, turn the rocker switch to “OFF” or adjust  
the thermostat (if installed) to a setting below room temperature.  
The pilot will remain lit for future burner ignition. For complete  
shutdown, see “TO TURN OFF GAS TO APPLIANCE” above.  
Adjusting the appliance to cause the flames to turn orange sooner may  
result in poor combustion, sooting and a hazardous situation. See Figure  
31 showing proper flame appearance.  
When testing for proper operation - If an optional thermostat is installed  
adjust it to its highest temperature setting. Visually determine that main  
burner gas is burning properly: i.e., no floating, lifting or flashback.  
Adjust the primary air shutter(s) as required. Check for proper main  
burner operation at both high and low flame.  
WARNINGS  
• Improper installation, adjustment, alteration,  
service or maintenance can cause injury or  
property damage. For assistance or additional  
information,consultaqualifiedinstaller,service  
agency or your gas supplier.  
• Operation of this appliance when not connected  
to a properly installed and maintained venting  
system can result in carbon monoxide (CO)  
poisoning and possible death.  
• Carbon monoxide poisoning – early signs of  
carbon monoxide poisoning resemble the flu  
with headaches, dizziness, or nausea. If you  
have these signs, get fresh air at once! Have  
the heater inspected by a qualified service  
technician. Some people are more affected by  
carbon monoxide than others. These include  
pregnant women, people with heart or lung  
disease or anemia, those under the influence  
of alcohol and those at high altitudes.

whentheblowerison.Theblowersoundsmaybereducedbyadjustingthe  
speedcontrollocatedontheblowerassembly.Also,aslightclickingsound  
may be heard as the gas valve or blower switch come on and off.  
Air Shutter Adjustment  
The air shutter control lever is located on the bottom of the stove directly  
to the left of the gas valve. The lever is linked to the primary air shutter on  
the main burner. The air shutter regulates the amount of primary air the  
burner receives and therefore how clean the stove burns. The air shutter  
should only be adjusted by a qualified gas technician. The stove should  
burn for about 15 minutes with the logs installed before adjusting the air  
shutter. Moving the lever down will open the shutter and turn the flames  
more transparent and blue. Moving the lever up will close the shutter  
and turn the flames more orange.  
Paint Curing  
This appliance has been painted with a high temperature metallic paint. It  
leaves the factory dry to the touch, but completes the curing process as  
the stove is used. To cure the paint, burn the appliance four successive  
times for ten minutes each time with a five minute cool down between  
each firing. Also some parts of the appliance may be lightly coated with  
machining oil. Ventilate the house during these first firings as the paint  
and oil give off carbon dioxide and unpleasant odors. It is recommended  
that persons sensitive to an imbalance in the indoor air quality avoid the  
appliance during the curing process.  
CAUTION: The air shutter should never be set so as to make the  
tips of the flames sooty or create sooting on the viewing glass,  
logs, or firebox ceiling. If soot begins to form after burning,  
the air shutter should be opened gradually until the sooting  
condition stops. Gas quality and gas pressure may vary which  
can affect the burning characteristics of the stove.  
Optional Wall Thermostat  
If an optional wall thermostat is to be installed, install the thermostat per  
the manufacturers instructions (provided with the thermostat). Failure  
to follow manufacturers instructions could result in a malfunction. Pay  
special attention to the thermostat location requirements. If the loca-  
tion requirements are not adhered to the appliance, erratic operation or  
failure may occur.  
Close  
Air Shutter Control Lever  
Do not mount the thermostat where it may be affected by:  
• Radiant heat from this appliance, fireplaces, sun or other heat  
sources.  
• Drafts or dead spots behind doors or in corners.  
• Hot or cold air from ducts.  
Open  
Optional Blower  
End View of Gas Valve  
An optional blower (part # 75194) may be installed on your stove to  
maximize heat distribution. See your Lennox Hearth Products dealer for  
blower information. The optional blower is equipped with a three-prong  
(grounding) plug for your protection against shock hazard and should  
be plugged directly into a properly grounded three-prong receptacle. Do  
not cut or remove the grounding prong from this plug.  
Figure 33  
Quiet Operation  
CAUTION: Label all wires prior to disconnection when servic-  
ing controls. Wiring errors can cause improper and dangerous  
operation.  
As the appliance is burning, a number of normal operational sounds may  
be heard. The flow of gas through the gas valve and orifice may make a  
rushing or whistling noise. If this noise is objectionable, it can be reduced  
by turning down the flame. Turning down the flame can reduce total heat  
output by more than 30%.

“On-Off” Switch, Thermostat Or Remote Control  
Your stove comes equipped with an “On/Off” rocker switch used to turn  
the burner on and off while the pilot light is on. The switch is a round  
rocker switch located behind the main control panel door.  
40 Feet  
25 Feet  
A millivolt wall thermostat, or a remote control, can be used to supple-  
ment the rocker switch. The gas valve is powered by millivolts generated  
by the pilot assembly. This millivolt system is very sensitive to electrical  
resistance, therefore, make sure all connections are tight, clean and free  
from corrosion. Do not splice any millivolt wires. Consult the table below  
to determine the proper gage of wire for the thermostat or wall switch  
connections. This table refers to the total length of the wire (out to the  
switch and back). The thermostat must be a millivolt type. A 24-volt  
furnace thermostat will not work. Never hook up household current - 120  
Volts - to the millivolt system. It is not recommended to hook up any  
more than two switches to the stove (for example a rocker switch and a  
wall thermostat). Additional switches may affect the system resistance  
and increase the chance of the burner not igniting.  
16 Feet  
Millivolt Control System  
This stove operates on a millivolt control system. As such, no additional  
power supply is needed for the stove to heat. The pilot assembly contains  
a thermocouple that, when heated by the pilot flame, generates electricity  
(millivolts- mV=1/1000 of a volt) which opens a valve allowing gas to  
continue flowing to the pilot assembly. The pilot assembly also contains a  
thermopile that, when heated by the pilot flame, generates electricity that  
flows to terminal #1 (labeled TPTH) on the gas valve. When the electricity  
is conducted from terminal #1 through the on/off switch, thermostat,  
or receiver of the remote control to terminal #3 (labeled TH) on the gas  
valve, the main burner will ignite.  
Follow the instructions included with the thermostat or remote control  
for wiring. The thermostat, remote control and rocker switch will turn the  
burner on and off independently. Be sure to set the rocker switch to the  
“Off” position when using the thermostat or remote control and set the  
thermostat or remote control to the lowest temperature when you wish  
to use the rocker switch only, otherwise one may override the other.  
CAUTION: Label all wires prior to disconnection when servic-  
ing controls. Wiring errors can cause improper and dangerous  
operation.

ing controls. Wiring errors can cause improper and dangerous  
operation. Verify proper operation after servicing.  
1. Annual inspection should be made and the following checks  
performed:  
o
When unit is cool, open glass viewing door and inspect burner for  
dirt, soot and lint accumulations and remove if necessary. If exces-  
sive soot accumulation is present on burner, have a qualified service  
technician adjust burner for proper combustion.  
o
o
o
o
o
Clean inside of glass viewing door with gas fireplace glass cleaner.  
NEVER attempt to open door or clean glass when unit is hot.  
Check the hot air outlet vents for lint or other accumulations. Never  
block or restrict vent openings or obstruct flow of ventilation air.  
Check that direct-vent pipe, air intake and flue are open and free of  
soot, blockage, or debris.  
Figure 35  
Check gaskets once a year. Gaskets must be tight. Replace if neces-  
sary.  
General Vent Pipe Maintenance

until after the gas pressure has been checked and supply lines have  
been completely bled (this may take an hour or more when bleeding  
through the pilot). All pilots are checked and burned at the factory  
prior to shipment. The pilot adjustment screw is located to the lower  
left of the flame height control knob.  
Conductaninspectionoftheventingsystemsemi-annually.Recommended  
areas to inspect are as follows:  
1. Check areas of the venting system which are exposed to the ele-  
ments for corrosion. These will appear as rust spots or streaks and  
in extreme cases, holes. These component should immediately be  
replaced.  
2. Remove the cap and shine a flashlight down the vent. Remove any  
bird nests or other foreign material.  
.25 Adjust the pilot screw to properly size the flames. The flames  
should completely surround the thermopile and thermocouple and  
extend across the main burner tube ports. Be careful not to back  
the screw out of its threads.  
3. Check for evidence of excessive condensate, such as water droplets  
forming in the inner liner and subsequently dripping out at joints.  
Continuous condensate can cause corrosion of caps, pipe and fit-  
tings. It may be caused by having excessive lateral runs, too many  
elbows and exterior portions of the system being exposed to cold  
weather.  
o
Check that the area around the stove is kept clear and is free of  
combustible materials, gasoline and other flammable vapors and  
liquids.  
o
Check the millivolt system as per the table on this page.  
4. Inspect joints to verify that no pipe sections or fittings have been  
disturbed and consequently loosened. Also check mechanical sup-  
ports such as wall straps or plumbers’ tape for rigidity.

WARNINGS  
Glass Door Cleaning And Maintenance  
• Do not attempt to substitute the materials used on  
these doors, or replace cracked or broken glass.  
• Handle this glass with extreme care! Glass is  
susceptible to damage – Do not scratch or handle  
roughly while reinstalling the glass door frame.  
• The glass door(s) of this appliance must only be  
replaced as a complete unit as provided by the  
manufacturer. Do not attempt to replace broken,  
cracked or chipped glass separately.  
• Do not attempt to touch the front enclosure glass  
with your hands while the appliance is in use.  
• Do not use abrasive cleaners. Never clean the  
glass when it is hot.  
Cleaning: When cooled, the glass may be cleaned with a clean, soft  
cloth and a household glass cleaner. For cleaning white condensation  
from the interior glass use a gas stove glass cleaner available from your  
stove dealer. Use of caustic or abrasive cleaners may damage glass. Gold  
or nickel plated trim must be cleaned with a household glass cleaner or  
denatured alcohol and a soft cloth before firing or fingerprints and stains  
will remain permanently. Never use abrasive polish to clean the gold or  
nickelasitwillruinthenish.DONOTspraycommercialglasscleanerwith  
ammonia on the door and glass gasket as it may dissolve the gasket glue.  
Glass Replacement: Should the glass be damaged, both the glass  
and the gasket should be replaced. The replacement glass and gasket  
are available from your Lennox Hearth Products dealer. The glass is  
neo-ceramic and alternative types must not be used. To install the new  
glass and gasket: Remove the old glass and gasket. The glass is held  
in place by two metal tabs located on the sides of the glass door frame.  
Using a flat-bladed screwdriver or pliers, bend the tabs up to release the  
old glass from the frame. Should the old glass be broken, care should be  
used in removing and discarding the glass so as not to injure yourself.  
Install the new glass and gasket by positioning the frame with the bent  
lips up and set the glass on the frame (the glass is square so there is no  
top or bottom). Slide the glass so the gasket is down against the 1/8”  
lip. Using pliers, bend the metal tabs firmly down onto the gasket on the  
glass. The tabs must be bent into the gasket to ensure a tight seal of the  
glass to the stove. Install the glass frame on the stove. See instructions  
on this page for removing and replacing the glass door. Replacement  
of the glass and gasket should be done by a qualified service technician.  
CAUTION  
Do not operate the appliance with glass removed,  
cracked or broken.

Opening and Removing Glass Door  
The doors on the stove may be opened to provide an unobstructed view  
of the fire or to provide greater access to the firebox. To open the doors,  
when the stove is cool, simply pull on the right door and it will swing  
open. The left door can then also be swung open.  
Lift off the stove top to access the glass door. At the top of the glass door  
are two spring-loaded “I” (looped) bolts. Pull each loop forward while  
rotating at 90 degrees, releasing the top of the glass door. To remove  
the door, grasp it firmly with both hands and lift it up. The glass door is  
fragile so it is important to place it in a secure spot until reinstalled. To  
reinstall the door, the bottom of the door must be inserted in the slot at  
the bottom of the firebox. The loops on the spring loaded “I” bolts must  
bepulledforwardanddownintothereceivingbracketonthedoortoapply

voltage.  
Check the connection between the thermocouple lead and the valve. Turn control knob to  
“pilot” and push in and light pilot. While lit, take millivolt reading at lead going into valve’s  
CPU. Minimum reading should be 17 millivolts. If less, replace thermocouple.  
Air in gas supply line.  
Purge air in pilot gas line by holding in control knob at “pilot” and sparking igniter. The air  
in the line may take up to several minutes to purge.  
Main burner will not  
burn.  
Pilot has gone out.  
See Lighting Instructions.  
Rocker switch or  
thermostat wires are  
defective.  
Disconnect rocker switch and thermostat wires at terminals 1 and 3 on valve. Jumper  
across from 1 to 3 with pilot lit. If burner comes on either rocker switch or thermostat wir-  
ing is not functioning.  
Make sure thermopile is fully engulfed by the pilot flame. Check thermopile with millivolt  
meter. With pilot lit and the rocker switch and thermostat off, the millivolt reading with the  
meter connected to valve terminals 1 and 2 should be after 2 minutes at least 325. If the  
thermopile lead connections are good at terminals 1 and 2 and readings are less than 325,  
replace faulty thermopile.  
Thermopile may not be  
generating sufficient  
millivolts.
