5.0 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. 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
III. Soot deposits
1. Air inlet blocked or restricted
1. Clean air inlets
2. Vent system is restricted or
inadequate
2. Confirm venting & termination are those
which are approved with the appliance
IV
.
Flame burns blue and lifts
off burner
1. Insufficient combustion air being
supplied
1. Ensure that no foreign material blocks air
inlets. Ensure the vent is adequate
2. Manifold pressure set too high
2. Check manifold pressure
3. Vent system restricted
3. Check vent system
V. Main flame does not burn
properly
1. Incorrect vent or termination
used.
1. Confirm venting & termination are those
which are approved with the appliance
VI. Flames impinge on firebox
top
1. Vent system is restricted or
inadequate
1. Correct flue as required
2. Manifold pressure too high
2. Check manifold pressure as required
