MAINTENANCE CHECKLIST

The following should only be performed by a qualified service
technician.
1. Annual inspection should be made and the following checks per-
formed:
o When unit is cool, remove glass and inspect burner for dirt, soot
and lint accumulations and remove if necessary. If excessive soot
accumulation is present on burner, have a qualified service technician
adjust the burner for proper combustion.
o Clean inside of glass with gas fireplace glass cleaner. NEVER attempt
to remove or clean the glass when the unit is hot.
o Check the hot air outlet vents for lint or other accumulations. Never
block or restrict vent openings, obstruct flow of ventilation air, or
use vents other than those approved for use with this appliance.
o Check that the chimney and its outlet are open and free of soot, block-
age, or debris. The venting system should be periodically examined
by a qualified agency.
o Check gaskets once a year. Gaskets must be tight. Replace if neces-
sary.
o Periodically inspect the pilot system for proper flame. Turn ON the
IPI switch (Intermittent Pilot Mode, ON [-] = Standing Pilot Mode).
Ensure the igniter lights the pilot. The pilot flame should engulf the
flame sensor as shown in Figure 26. See Intermittent/Standing Pilot
Mode on Page 22 for instructions on switching from intermittent
ignition to a standing pilot.
o Periodically inspect the burner flame for proper appearance. See
Flame Color and Behavior on Page 23.
o Check that the area around the insert is kept clear and is free of com-
bustible materials, gasoline and other flammable vapors and liquids.
2. The viewing glass should be cleaned periodically (see Glass Main-
tenance).
