Troubleshooting
With proper installation, operation, and maintenance your gas appliance will provide years of trouble-free service. If you
do experience a problem, this troubleshooting guide will assist a qualifi ed service technician in the diagnosis of a problem
and the corrective action to be taken. This troubleshooting guide can only be used by a qualifi ed service technician. Con-
tact your dealer to arrange a service call by a qualifi ed service technician.
A. Intellifi re Ignition System
Symptom Possible Cause Corrective Action
1. Pilot won’t light. The
ignitor/module makes
noise, but no spark.
Note: Red LED may fl ash
twice on the Module.
A. Incorrect wiring. Verify “S” wire (white) for sensor and “I” wire (orange) for ignitor
are connected to correct terminals on module and pilot assembly.
B. Loose connections or electrical
shorts in the wiring.
Verify no loose connections or electrical shorts in wiring from
module to pilot assembly. Verify connections underneath pilot
assembly are tight; also verify connections are not grounding
out to metal chassis, pilot burner, pilot enclosure, mesh screen if
present, or any other metal object.
C. Ignitor gap is too large. Verify gap of igniter to right side of pilot hood. The gap should be
approximately .17 inch or 1/8 in. (3 mm).
D. Module. Turn ON/OFF rocker switch or remote to OFF position. Remove
ignitor wire “I” from module. Place a grounded wire about 3/16 in.
(5 mm) away from “I” terminal on module. Place ON/OFF rocker
switch or remote in ON position. If there is no spark at “I” terminal
module must be replaced. If there is a spark at “I” terminal, module
is fi ne. Inspect pilot assembly for shorted sparker wire or cracked
insulator around electrode. Replace pilot if necessary.
2. Pilot won’t light, there is no
noise or spark.
Note: Red LED may fl ash
twice on the Module.
A. No power or power supply
installed incorrectly.
Verify that power supply is installed and plugged into module
and/or batteries are installed in the battery pack. Check voltage of
power supply under load at spade connection on module with ON/
OFF switch in ON position. Acceptable readings of a good power
supply are between 4 and 7.5 volts AC.
B. A shorted or loose connection
in wiring confi guration or wiring
harness.
Remove and reinstall the wiring harness that plugs into module.
Verify there is a tight fi t. Verify pilot assembly wiring to module.
Remove and verify continuity of each wire in wiring harness.
Replace any damaged components.
C. Improper wall switch wiring. Verify that 120 VAC power is “ON” to junction box.
D. Module not grounded. Verify black ground wire from module wire harness is grounded to
metal chassis of appliance.
E. Module. Turn ON/OFF rocker switch or wall switch to OFF position.
Remove ignitor wire “I” from module. Place ON/OFF rocker switch
or remote in ON position. If there is no spark at “I” terminal module
must be replaced. If there is a spark at “I” terminal, module is
fi ne. Inspect pilot assembly for shorted sparker wire or cracked
insulator around electrode.
3. Pilot won’t light, there is no
noise or spark.
Red LED fl ashes once on
the module. A. Fuel selector is not in the
correct position.
Turn module selector switch to off.
Turn fuel to correct fuel type.
Turn module selector to switch or remote (if a remote is installed)
