IMPORTANT
Keep your house well ventilated
during the curing process. The
odor and haze emitted by the
curing process can be quite
noticeable and may set off a
smoke detector.
Lighting Millivolt Appliances
To light millivolt appliances refer to the detailed
lighting instructions found on Page 16 (Eng-
lish) and Page 17 (French). Millivolt appliance
lighting instructions may also be found on the
pull-outlightinginstructionlabelslocatedinthe
control compartment (below glass door).

CONTROL COMPARTMENT ACCESS
Pull down hinged door to access control
compartment (see Figure 3).
Test gauge connections are provided on the
front of the millivolt gas control valve (identi-
fied IN for the inlet and OUT for the manifold
side). See Figures 1 & 2.
This appliance must not be connected to a
chimney or flue serving a separate solid-fuel
appliance.
Burn-in Period
During the first few burns of these appliances
there will be some odor due to the curing of the
high temperature paint and burning off of lubri-
cants used in the manufacturing process.
Depending on your use, the burn-in period may
take a few hours or a few days. Do not turn on
blower during Burn-In period.
GAS CONTROLS
See Figure 3, showing how to access the
control compartment.
These millivoltappliancesarefittedwitha burner
ON/OFF Switch, located on the side surround
panel as shown in Figure 4 on Page 4. Once
the pilot is lit, and valve knob is in the ON posi-
tion, theON/OFFswitchwillcontroltheappliance
ON/OFF operation. To operate, toggle the switch
between its ON and OFF positions.
Variable Flame Height Adjustment
These millivolt appliances are equipped with a
variable gas control valve. Flame height may be
adjustedthrougharangebetweenfixedlowand
high settings by rotating the HI/LO knob on the
valve (see Figures 1 & 2)alternately, while the
appliances are in operation.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE
WARNING
Turnoff gasand electricalpower
before servicing the appliance.
IMPORTANT
Always verify proper operation
after servicing.
OPERATION AND CARE OF YOUR
APPLIANCE
Appliance operation may be controlled through
a remotely located optional wall thermostat or
remote control.
Inlieu of remote control or remotewall thermo-
stat operation, the appliance must be operated
directlythroughtheon/offswitchlocatedonthe
surround panel (see Figure 4).
If your millivolt appliance is equipped with an
optional wall thermostat kit or remote control
kit and the pilot is lit (and valve is in the On
position), the appliance main burner may be
turned on and off with the wall thermostat or
remote control.
Always keep the appliance area clear and free
fromcombustible materials,gasolineand other
flammable liquids.
Remember, Millivoltapplianceshave a continu-
ous burning pilot flame. Exercise caution when
using products with combustible vapors.
MAINTENANCE
The appliance and venting system should be
thoroughly inspected before initial use and at
least annually by a qualified service technician.
However, more frequent periodic inspections
and cleanings should be performed by the
homeowner. Homeowner must contact a quali-
fied service technician at once if any abnormal
condition is observed.
Refer to the maintenance schedule on Page
7for maintenance tasks, procedures, recom-
mended frequency and by whom they should
be performed. Always verify proper operation
of the appliance after servicing.
Always turn off the gas to the appliance before
cleaning.Beforere-lighting,refertothelighting
instructionsinthismanual.Instructionsarealso
foundonpull-outpanelslocatedbelowtheglass
door in the control compartment.
Keep lower control compartment clean by
vacuuming or brushing at least twice a year.
More frequent cleaning may be required due to
excessivelintfromcarpeting,beddingmaterials,
etc. It is important that control compartments,
burners and circulating air passageways of the
appliance be kept clean.
CAUTION
Wear gloves and safety glasses
for protection while doing
required maintenance.
Check Burner Flame Appearance
Visually check the flame of the burner periodi-
cally making sure the flames are steady and not
lifting or floating (see Figure 19 on Page 8).
Glass Cleaning
Note: Clean glass after first two weeks of opera-
tion (after Burn-In period is over).
The viewing glass should be cleaned periodi-
cally to remove any build-ups caused from the
following:
• During start-up, it is normal for condensa-
tion to form on the inside of the glass (this
condensation and fog will usually disappear
in a few minutes). This can cause lint, dust
and other airborne particles to cling to the
glass surface.
• Initial curing of the high temperature paint
and burning off of lubricants used in the
manufacturing process may result in a film
on the glass.
• A white coating may form on the glass as a
result of impurities and minerals in the fuel.
It is recommended that the glass be cleaned
two or three times during each heating season,
depending on the circumstances present.
Use one of the following to clean glass:
• Non-ammonia based household cleaner
• 50%-50% mix of white vinegar & water
• gas stove glass cleaner
Servicing Blower
Refer to blower wiring diagram on Page 13.
To access the blower assembly for mainte-
nance, adjustment or replacement, see the
following procedure:
1. Unplug 120-volt A.C. power supply to
insert.
2. Shut off gas supply to insert.
3. Remove Glass Door (see Procedure For
Removing Standard Glass Door Assembly
