Carbon Monoxide Poisoning: Early signs of
carbon monoxide poisoning are similar to the

emit a slight odor for an hour or two. This is
due to the “burn-in” of internal paints and
lubricants used in the manufacturing process.

Glass Cleaning
3. Keep lower control compartment clean by
vacuuming or brushing at least twice a year.
Morefrequentcleaningmayberequireddueto
excessive lint from carpeting, bedding materi-
als, etc. It is important that control compart-
ments, burners and circulating air passage-
ways of the appliance be kept clean.
It will be necessary to clean the glass periodi-
cally. During start-up it is normal for conden-
sation to form on the inside of the glass. This
can cause lint, dust and other airborne par-
ticles to cling to the glass surface. Also initial
paint curing may deposit a slight film on the
glass. It is therefore recommended that the
glass be cleaned two or three times with a non-
ammonia household cleaner and warm water
(agasfireplaceglasscleanerisrecommended).
After that the glass should be cleaned two or
three times during each heating season, de-
pending on the circumstances present.
Maintenance
IMPORTANT: TURN OFF GAS AND ANY
ELECTRICAL POWER BEFORE SERVICING
THE APPLIANCE.
4. Always turn off gas to the pilot (millivolt
appliances) before cleaning. Before re-light-
ing, refer to the lighting instructions in this
manual. Instructions are also found on a pull-
out panel located on the floor of the appliance.
The appliance and venting system should be
thoroughly inspected before initial use and at
least annually by a qualified service techni-
cian. However, more frequent periodic inspec-
tions and cleanings should be performed by
the homeowner. Homeowner must contact a
qualified service technician at once if any
abnormal condition is observed.
5. Always keep the appliance area clear and
free from combustible materials, gasoline and
other flammable liquids.
Note: Clean glass after first two weeks of
operation.
6. Remember, Millivolt appliances have a con-
tinuous burning pilot flame. Exercise caution
when using products with combustible vapors.
WARNING: DO NOT USE ABRASIVE
CLEANERS. NEVER CLEAN THE GLASS
WHEN IT IS HOT.
Refer to the maintenance schedule for mainte-
nance tasks, procedures, periodicity and by
whom they should be performed. Always
verify proper operation of the appliance after
servicing.

Sooting is indicated by black puffs developing
at the tips of very long orange flames. Sooting
results in black deposits forming on the logs,
appliance inside surfaces and on exterior sur-
faces adjacent to the vent termination.
These are direct-vent appliances. They are
designed to operate only when the front glass
enclosure panel is installed. Generally the
front glass enclosure panel should not be
removed except to gain access to the compo-
nents within the firebox, and the appliance
may only be operated without the front glass
enclosure panel in place for very brief periods
of time during appliance checkout and adjust-
ment. Be sure that the flame appearance will
be diminished while the front glass enclosure
panel is removed.

If the logs are properly positioned and sooting
conditions exist, the air shutter opening on the
main burner tube should be adjusted. Nor-
mally, the more elbows and horizontal runs
there are in the vent system, the greater the
need for the air shutter to be opened further.
