5.0 TROUBLE SHOOTING
SYMPTOM POSSIBLE CAUSE CORRECTIVE ACTION
I. Pilot will not light after
repeated triggering of the
piezo ignition button
A. No spark at electrode (weak or not heat source for pilot ignition)
1. Improper ignition 1. Align the electrode with 1/8” (3mm) gap
to pilot hood
2. Poor connections at igniter
and ignition electrode
2. Reconnect if loose
3. Broken ceramic cover on
ignition electrode
3. Replace pilot assembly
4. Defective piezo igniter 4. Replace piezo igniter
B. No gas or low gas pressure
1. Gas line shut off(s) may not be
turned on
1. Turn of shut-off valves
2. No gas supply (LPG) 2. Check propane tank; you may be out of
fuel
3. Air in gas lines 3. Purge gas lines
4. Gas lines may not be
connected
4. Connect all gas lines
5. Low pressure may be caused
by bent line
5. Check for a kinked line
6. Valve control knob not fully
depressed in “PILOT” position
6. Fully depress control knob
II. Pilot will not stay lit after
following the lighting
instructions
A. Thermocouple / Valve
1. Weak or improperly located
pilot flame
1. Adjust and clean pilot. The flame must
impinge on or engulf the thermocouple.
2. Defective thermocouple 2. Have the thermostat contacts open and
pilot lit with the knob turned to the "Pilot"
position. Reading should be a minimum
of 18 mV for a new thermocouple, if the
reading is less than 18mV replace the
thermocouple.
3. Thermocouple not installed
properly
3. Make sure all wire connections at the gas
valve terminals are tight and the
thermocouple is fully inserted into the
mounting bracket
4. Open wire connection in pilot
circuit
4. Check wire continuity and connections in
the pilot circuit
