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 ac
cumulation 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.
o
Check gaskets once a year. Gaskets must be tight. Replace if neces
sary.
o
Inspect the pilot system for proper flame. NEVER ADJUST THE PILOT
until after the gas pressure has been checked and the supply lines have
been completely bled (this may take an hour or more when bleeding
through the pilot). All pilots are checked and burned at the factory
prior to shipment. The pilot adjustment screw is located below the
ON/OFF/PILOT control knob. Remove the pilot adjusting cover with
a flatbladed screwdriver to access the pilot adjusting screw. Adjust
the pilot screw to properly size the flames. The flames should directly
contact the thermopile and extend across the main burner ports. Be
careful not to back the screw out of its threads. Replace the cover
and check for gas leaks using a gas leak test solution.
