A qualified service person recommended by your Empire dealer
should conduct an annual inspection and maintenance of the ap-
pliance, its venting, and the installation to keep it running safely
and efficiently. The following procedures should be performed only
by a qualified service person. The gas supply should be turned off
whenever a maintenance procedure is performed.
If the glass front, relief doors, or front access door are removed for
servicing, they must be replaced prior to operating the appliance.
Glass Cleaning
It will be necessary to clean the glass periodically. During start-up
condensation, which is normal, forms on the inside of the glass and
causes lint, dust and other airborne particles 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-abrasive household cleaner and warm water (we
recommend gas fireplace glass cleaner). We do not recommend
using packaged spray type household glass cleaner. After that the
glass should be cleaned two or three times during each heating
season depending on the circumstances present.
General Glass Information
Only glass approved for use in Empire Comfort Systems Inc.
fireplaces may be used for replacement. The glass replacement
should be done by a licensed or qualified service person.
WARNING
1. The use of substitute glass will void all product warranties.
2. Care must be taken to avoid breakage of the glass.
3. Under no circumstances should this appliance be operated
without the glass front or with a broken glass front.
Replacement of the glass (with gasket) as supplied by the
manufacturer should be done by a qualified service person.
4. Do not abuse the glass by striking or hitting the glass.
WARNING
Do not use abrasive cleaners on glass. Do not attempt to
clean glass when glass is hot.
Failure to follow these warnings could cause a serious safety issue
to the operator, such as fire or other serious conditions.

IMPORTANT:
Turn off gas before servicing appliance. It is
recommended that a competent service technician perform these
check-ups at the beginning of each heating season.
• DO NOT put anything around the heater that will obstruct
the flow of combustion and ventilation air. See clearances.
• DO examine venting system periodically. Clean and replace
damaged parts. Examinations should be made at the start
of the heating season and also in mid heating season under
average conditions.
• Clean Burner and Control Compartment
Keep the control compartment, logs, and burner areas
surrounding the logs clean by vacuuming or brushing at least
twice a year.
