TROUBLE SHOOTING - INTERMITTENT PILOT
SYMPTOM
POSSIBLE CAUSE
CORRECTIVE ACTION
I. Pilot will not light after repeated
triggering of the remote control –
intermittent pilot
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 starter
and ignition electrode
2. Reconnect if loose
1. Broken ceramic cover on
ignition electrode
3. Replace pilot assembly
2. Battery power low or dead
4. Replace batteries
B. No gas or low gas pressure
5. Gas line shut off(s) may not
be turned on
5. Turn on shut-off valves
1. Air in gas lines
1. Purge gas lines
2. Gas lines may not be
connected
2. Connect all gas lines
3. Low pressure may be
caused by bent line
3. Check for a kinked line
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, as
shown in Figure 27.
2. Defective thermocouple
2. Replace 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
5. Defective Valve
5. Check with your voltmeter.
B. Defective safety circuit
1. Loose or defective connections 1. Check continuity, tighten wiring or
connections, and repair
III. Main burner will not light
A. Valve / Switches
1. Valve control off
1. Turn to “ON” position
2. Blockage at the burner (line,
orifice, or ports)
2. Check and clean
3. Defective remote
1. Conduct a continuity test or jumper
wire test and replace if defective,
check batteries
4. Defective wiring or
connections
2. Conduct a test with a jumper wire and
repair as required
5. Defective Valve
3. Contact service technician
I. Soot deposits
1. Air inlet blocked or restricted
1. Clean air inlets
2. Incorrect media position
2. Make sure there is only glass
coverage on the burner area.
