TROUBLESHOOTING
SYMPTOM
ACTION
Pilot will not light after pressing
the sparker many times.
1. When lighting the appliance for the first time after installation or after servicing,
there is air in the gas line. It takes a while for all the air to purge out of the pilot
before gas can reach the pilot and ignite. Remove the glass door and try
lighting the pilot many times to purge the air.
2. Check to make sure the gas supply to the appliance is turned on and there is
adequate gas supply pressure to the appliance.
3. Check for sparks between the spark electrode and the pilot head when the
sparker is pressed. If there are no sparks,
a. Check for broken or poor connection from the sparker to the electrode.
b. Check for the spark shorting or arcing at other locations.
c. Check for defective sparker.
d. Check for defective spark electrode.
4. With the door removed, try lighting the pilot with a match.
a. If air is blowing on the flame of the match, hold the control knob in at the
‘
PILOT
’
setting until all the air is purged out of the line.
b. If there is no gas or air coming out of the pilot and there is gas pressure to
the appliance, the pilot orifice may be blocked or the gas valve may be
defective.
Pilot will not remain on after being
lit.
1. Press the control knob all the way in (at the
“
pilot
”
indicator).
2. Hold the control knob in for a longer period of time.
3. If you are trying to re
-
light the pilot immediately after you have shut
-
off the pilot,
you have to wait 5 minutes for the valve to reset. (safety system built into the
valve)
4. Check to see if the pilot flame is large enough to reach and surround the
thermocouple. If the flame is too small, check for correct gas supply pressure.
If pressure is good, adjust the pilot flame size with the adjustment screw on the
valve. If the flame cannot be adjusted, there might be some debris obstructing
the pilot orifice, or a wrong size pilot orifice.
5. Check for poor connection of the thermocouple to the valve.
6. Check for proper millivolts of the thermocouple. The thermocouple should
generate at least 30 mV or it is defective.
7. Check for defective gas valve.
The pilot was lit but will random-
ly go out.
1. Turn the fireplace on again. If the fireplace includes continuous pilot on de-
mand ignition, the system will turn off the pilot if the fireplace has not been
used for seven days.
2. If the fireplace includes continuous pilot on demand ignition, the pilot wires
connected to the valve may be reversed. See Page 30.
2. Have a service technician check for low inlet pressure.
The main burner does not turn on
with the pilot lit.
1. Check to make sure the control knob is turned to the
‘
ON
’
position.
2. Allow enough time for the pilot to heat up the thermopile to generate sufficient
voltage to activate the valve.
Please check to make sure the instructions are followed exactly before attempting
troubleshooting of the appliance.
WARNING:
Troubleshooting and servicing of gas and electrical devices of the appliance should
only be conducted by a qualified service technician.
