Glass Cleaning

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
(a gas fireplace glass cleaner is recommended).
After that the glass should be cleaned two or
three times during each heating season, de-
pending on the circumstances present.
Note: Clean glass after first two weeks of
operation.
WARNING: DO NOT USE ABRASIVE
CLEANERS. NEVER CLEAN THE GLASS
WHEN IT IS HOT.
CAUTION: DO NOT ATTEMPT TO TOUCH THE
FRONT ENCLOSURE GLASS WITH YOUR
HANDS WHILE THE FIREPLACE IS IN USE.

Maintenance

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 in-
spections and cleanings should be performed
by the homeowner. Homeowner must contact
a qualified service technician at once if any
abnormal condition is observed.
Keep side control compartment clean by vacu-
uming or brushing at least twice a year. More
frequent cleaning may be required due to
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.
Always turn off gas to the pilot (millivolt appli-
ances) before cleaning. Before re-lighting, re-
fer to the lighting instructions in this manual.
Instructions are also found on pull-out light-
ing instruction labels attached to the gas valve.
Always keep the appliance area clear and free
from combustible materials, gasoline and other
flammable liquids.
Remember, Millivolt appliances have a con-
tinuous burning pilot flame. Exercise caution
when using products with combustible vapors.
