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 acceptable, and if the burner does not come on, replace the gas
valve.
Check the burner orifice for stoppage. Remove stoppage.
Check the wall switch and wires for proper connections. Place the
jumper wires across the terminals at the wall switch. If the burner
comes on, replace the wall switch. If the wall switch is OK, place
the jumper wires across the wall switch wires at the gas valve. If the
burner comes on, the wires are faulty or connections are bad.
Clean thermocouple and adjust the pilot flame for proper flame
impingement. Follow lighting instructions carefully.
Check the LP (propane) tank. Refill the fuel tank.
Verify with manometer. NG should read 5-14 inches w.c. LP should
read 10-14 inches w.c.
Check venting system for damage. Replace/repair improperly
assembled pipe sections.
Check to ensure glass is installed properly. Replace glass panel
assembly.
Replace pilot if necessary.
Check for proper installation and freedom from debris or blockage.
This appliance is equipped with an auto reset high limit switch
which will shut down the appliance if it spills under flue blockage or
excessive negative pressure conditions. Shut off the appliance and
the gas supply. Do not attempt to operate the appliance until it has
been examined by a qualified service technician.
Adjust the log set so that the flame does not excessively impinge on
it. Refer to log instructions.
Refer to manual for shutter set points. Ensure that set point is correct
for appliance/gas type. If unit has adjustable shutter, it may be
necessary to increase shutter opening.
Inspect the opening at the base of the burner. NO MATERIAL
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.
