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.

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

Burner Flame Appearance
To reinstall glass door assembly panel, reverse instructions 1 - 3 on
this page.
BURNER ADJUSTMENT
Flame Appearance and Sooting
Properflameappearanceisaflamewhichisblueatthebaseandbecomes
yellow/orange in the body of the flame. When the insert is first lit, the
entire flame may be blue and will gradually turn yellow/orange during
the first 6-8 minutes of operation. If after 6-8 minutes the flame stays
blue, or if the flame is orange with evidence of sooting (black tip), the
air shutter may require adjustment.
An appliance operated with an air shutter opening that is too large will
exhibit flames that are blue and transparent. These weak, blue and
transparent flames are termed anemic. If the air shutter opening is too
small, sooting may develop.
Sooting is indicated by black puffs developing at the tips of very long
orangeflames. Sooting results in black deposits formingon the logs,
appliance inside surfaces and on exterior surfaces adjacent to the
venttermination. Sooting is caused by incomplete combustionin the
flames and lack of combustion air entering the air shutter opening.
To achieve a warm yellow-to-orange flame that does not soot, the
shutter opening must be adjusted between these two extremes.
No smoke or soot should be present. Reposition the logs if flames
impinge on any of them. If the logs are properly positioned and
sooting conditions exist, the air shutter opening on the main burner
tube should be adjusted.
