5.0 TROUBLE SHOOTING

SYMPTOM
I. Pilot will not light after
repeated triggering of the
remote control
intermittent pilot
II. Pilot will not stay lit after
following the lighting
instructions
III. Main burner will not light
POSSIBLE CAUSE
A. No spark at electrode (weak or not heat source for pilot ignition)
1. Improper ignition
2. Poor connections at starter
and ignition electrode
3. Broken ceramic cover on
ignition electrode
4. Battery power low or dead
B. No gas or low gas pressure
1. Gas line shut off(s) may not be
turned on
2. Air in gas lines
3. Gas lines may not be
connected
4. Low pressure may be caused
by bent line
A. Thermocouple / Valve
1. Weak or improperly located
pilot flame
2. Defective thermocouple
3. Thermocouple not
properly
4. Open wire connection in pilot
circuit
5. Defective Valve
B. Defective safety circuit
1. Loose or defective connections
A. Valve / Switches
1. Valve control off
2. Blockage at the burner (line,
orifice, or ports)
3. Defective remote
CORRECTIVE ACTION
1. Align the electrode with 1/8 (3mm) gap
to pilot hood
2. Reconnect if loose
3. Replace pilot assembly
4. Replace batteries
1. Turn on shut-off valves
2. Purge gas lines
3. Connect all gas lines
4. Check for a kinked line
1. Adjust and clean pilot. The flame must
impinge on or engulf the thermocouple,
as shown in Figure 27.
2. Replace thermocouple
installed 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
5. Check with your voltmeter.
1. Check continuity, tighten wiring or
connections, and repair
1. Turn to ON position
2. Check and clean
3. Conduct a continuity test or jumper wire
test and replace if defective, check
batteries
