Troubleshooting the Gas Control System
⚠
WARNING
BEFORE DOING ANY GAS CONTROL SERVICE WORK, REMOVE THE GLASS FRONT.
NOTE: Before troubleshooting the gas control system, be sure external gas shut off is in the "On" position.
Problem
Possible Causes
Corrective Action
Spark igniter will not
light.
Defective or misaligned
electrode at pilot.
Check for spark at electrode and pilot: if no spark and electrode wire is
properly connected, replace igniter.
Defective igniter (push-
button).
Using a match, light pilot. If pilot lights, turn off pilot and push the red
button again. If pilot will not light - check gap at electrode and pilot
should be 1/8" to 1/4" to have a strong spark.
Pilot will not stay lit after
carefully following
lighting instructions.
Defective thermocouple
(flame switch where
applicable).
Check pilot flame. Must impinge on generator and thermocouple. Clean
and/or adjust pilot for maximum flame impingement on generator and
thermocouple. Replace thermocouple if pilot will not hold. (Hand tight
1/8 turn on replacement)
Defective valve magnet.
Replace valve, if pilot won't hold after the thermocouple is replaced.
Pilot burning, no gas to
burner, valve knob “ON”,
and wall switch “ON”.
Wall switch or wires
defective.
Check wall switch and wires for proper connections. Jumper wire
across terminals at wall switch. If burner comes on, replace defective
wall switch. If okay, jumper wires, across wall switch wires at valve. If
burner comes on, wires are faulty or connections are bad.
Generator may not be
generating sufficient
voltage.
Check generator with millivolt meter. Take reading at generator
terminals of gas valve. Should read 325 millivolts minimum while
holding valve knob depressed in pilot position and wall switch "off"
Replace faulty generator if reading is below specified minimum.
Plugged burner orifice.
Check burner orifice for stoppage and remove.
Defective automatic valve
operator.
Remove wall switch wires from gas valve. Install jumper wires from top
bottom terminals of gas valve. Turn valve on "ON". If main burner does
not light, replace valve.
Frequent pilot outage
problem.
Pilot flame may be too low
or blowing (high) causing
the pilot safety to drop out.
Clean and/or adjust pilot flame for maximum flame impingement on
generator and thermocouple.
*See NOTE below – Seven Day Timer
Flame lifts off burner
and goes out in less
than 30 seconds.
Inner 4” liner has come off
flue or termination, flame is
starving for oxygen.
Attach 4" liner to flue or termination using screws, silicone and clamps
as stated in manual.
Flame lifts off burner on
one side while the rest
of the flame remains lit.
Improper installation of
firebrick. Firebrick is likely
leaning.
Be sure to position firebrick against firebox walls and be sure to use
brick clips attached to the inner side of firebox.
*NOTE:
The pilot system for this appliance may be equipped with a
Seven Day Timer
, in which case the pilot flame will
be extinguished if the main burner has not been turned ON for seven days.
This Seven Day Cycle is reset every time the main burner is cycled ON / OFF and the pilot remains lit.
If more than seven days has passed since the main burner has been cycled ON / OFF and the pilot is also out, follow
the procedures described in this manual to light the pilot.
