Corrective Action
Turn the valve knob to the ON position. Place the
ON/OFF switch in the ON position. Check the millivolt
meter a the thermopile terminals. The millivolt meter
should read greater than 125mV. If the reading is ac-
ceptable, and if the burner does not come on, replace
the gas valve.
Check the burner orifi ce for stoppage. Remove stop-
page.
Follow the corrective action in Symptom and Pos-
sible Cause 1.a above. Check the switch and wiring.
Replace where defective.
Allow the unit to cool. If the burner remains lit after
the fi replace warms up, the switch is good.
Clean thermocouple and adjust the pilot fl ame for
maximum fl ame impingement. Follow lighting instruc-
tions carefully.
Check the LP (propane) tank. Refi ll the fuel tank.
Check venting system for damage. Replace/repair
improperly assembled pipe sections.
the horizontal vent cap should slope down only
enough to prevent any water from entering the unit.
The maximum downward slope is 1/4 inch.
Replace glass panel assembly.
Replace if necessary.
Check for proper installation and freedom from debris
or blockage.
Adjust the log set so that the fl ame does not exces-
sively impinge on it.
Adjust the air shutter located on the control panel.
Inspect the opening at the base of the burner. NO MA-
TERIAL SHOULD BE PLACED IN THIS OPENING.
Ensure that the vent cap is installed properly and free
of debris. Ensure that the vent system joints are tight
and have no leaks.
Ensure that no debris has been placed at the base of,
or in the area of the air holes in the center of the base
pan beneath the burner.
Ensure that the glass is tightened properly on the unit,
particularly on top corners.
