5.0 TROUBLE SHOOTING
SYMPTOM
I.
Pilot will not light after
repeated triggering of the
piezo ignition button
II. Pilot will not stay lit after
following the lighting
instructions
POSSIBLE CAUSE
A. No spark at electrode (weak or not heat source for pilot ignition)
1. Improper ignition
2. Poor connections at igniter
and ignition electrode
3. Broken ceramic cover on
ignition electrode
4. Defective piezo igniter
B. No gas or low gas pressure
1. Gas line shut off(s) may not be
turned on
2. No gas supply (LPG)
3. Air in gas lines
4. Gas lines may not be
connected
5. Low pressure may be caused
by bent line
6. Valve control knob not fully
depressed in "PILOT" position
A. Thermocouple / Valve
1. Weak or improperly located
pilot flame
2. Defective thermocouple
3. Thermocouple not installed
properly
4.
Open wire connection in pilot
circuit
CORRECTIVE ACTION
1. Align the electrode with 1/8" (3mm) gap
to pilot hood
2. Reconnect if loose
3. Replace pilot assembly
4. Replace piezo igniter
1. Turn of shut-off valves
2. Check propane tank; you may be out of
fuel
3. Purge gas lines
4. Connect all gas lines
5. Check for a kinked line
6. Fully depress control knob
1. Adjust and clean pilot. The flame must
impinge on or engulf the thermocouple, as
shown on page 31.
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. Make sure all wire connections at the gas
valve terminals are tight and the
thermocouple is fully inserted into the
mounting bracket
4. Check wire continuity and connections in
the pilot circuit
