VII. MAINTENANCE INSTRUCTIONS
Cleaning the Burner and Control Compartment.
Keep the burner compartment clean. Brush this area with a
clean, dry paint brush and vacuum at least once a year.
Always turn off the gas valve and "ON/OFF" switch before
cleaning.
Checking Flame Patterns.
Visually check the flame of the burner periodically, making
sure the flames are steady; not lifting or floating. The flame
color should be blue with yellow tips. The thermopile tip
should be covered with flame. See Figure 26.
Note: If the air shutter is open all the way and
the flames remain sooty, shut off gas to the
appliance and contact a qualified gas service
technician.
If the vent configuration is installed incorrectly, the vent
may cause the flames inside the appliance to lift or
"ghost" - a dangerous situation. Inspect the flames after
installation to ensure proper performance. If the vent con-
figuration is correct, yet the flames are lifting or ghosting,
shut off gas to the appliance and contact the dealer for
information on remedying the problem. Refer to Figure 27.
Venting System Inspection.
The heater and venting system should be inspected before use
each season, and at least annually, by a qualified field service
person, to ensure that the flow of combustion and ventilation
air is not obstructed.
Cleaning the Glass.
It is recommended to wear gloves while handling or removing
the glass. DO NOT REMOVE THE GLASS WHEN HOT.
Note: When cleaning the glass, NEVER use ab-
rasive materials. NEVER clean glass when hot.
To open the door and remove the glass for cleaning, follow
Step A on page 18.
To clean the glass, use a non-abrasive, mild cleaning solu-
tion. For example, a glass cleaner or for stubborn film, an
oven cleaner. Apply an adequate amount to the glass and
wipe off with a damp cloth. Be sure all cleaner is thoroughly
rinsed from the glass.
Never operate this heater without the glass properly secured
in place or if the glass is broken.
In the event of glass breakage, follow door removal instruc-
tions. This will allow the removal of all glass fragments and
sheet metal edge protection strips. Vacuum all remaining
glass pieces with a shop vac. (DO NOT VACUUM IF
PIECES ARE HOT.) Replace glass ordered direct or through
your local distributor. Never use substitute material. Only
ceramic glass may be used on this heater.
Log Cleaning.
Logs can be easily lifted out of position. Carbon build-up can
be removed with a vacuum cleaner.
