N. MAINTENANCE INSTRUCTIONS
1. CLEANING THE BURNER AND CONTROL
COMPARTMENT
Keep the burner and control compartment clean by
brushing and vacuuming at least once a year. Failure to
do so may shorten the life of the components. Always
turn off the wall switch (or remote control) and gas valve
before cleaning.
2. CHECKING THE VENTING SYSTEM
The appliance and venting system should be inspected
before use, and at least annually, by a qualified field
service person, to ensure that the flow of combustion
and ventilation air is not obstructed.
3. CHECKING FLAME PATTERNS
Check the flame pattern of the burner periodically, making
sure the flames are steady, not lifting or floating. The flame
color should be blue with yellow tips. See Figures 44 and
45.
The thermopile and thermocouple tips should be covered
with flame. See Figure 46.
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. See Figures 44 and 45. If the
vent configuration is correct, yet the flames are lifting or
ghosting, shut off gas to the appliance and contact the
dealer.
To prevent the possibility of soot buildup, we have
provided your appliance with an adjustable air shutter.
Your air shutter is set at 1/4 open for natural gas and
fully open for propane. In the event soot is
accumulating in your appliance, the air shutter should
be opened farther.
Note:
The look of the flames and embers may differ
based on the type of fuel and venting assembly that is
used.
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.
