TROUbLEShOOTING
WARNING: Turn off heater and let cool before servicing. Only a
qualified service person should service and repair heater.
CAUTION: Never use a wire, needle or similar object to clean
pilot. This can damage pilot unit.
Note: All troubleshooting items are listed in order of operation.
The two most common causes of a malfunctioning gas appliance are:
1. Loose wiring connections
2. Construction debris clogging the pilot and/or gas control valve filter
MILLIvOLT IGNITION
POSSIBLE CAUSE
1. Ignitor electrode not con
-
nected to ignitor cable
2. Ignitor cable pinched or
wet
3. Piezo ignitor nut is loose
4. Broken ignitor cable
5. Bad piezo ignitor
6. Ignitor electrode broken
7. Ignitor electrode positioned
wrong
REMEDY
1. Reconnect ignitor cable
2. Free ignitor cable if pinched
by any metal or tubing.
Keep ignitor cable dry
3. Tighten nut holding piezo
ignitor. Nut is located behind
the mounting bracket
4. Replace ignitor cable
5. Replace piezo ignitor
6. Replace pilot assembly
7. Tighten electrode. Replace
if necessary
OBSERvED PROBLEM
When ignitor button is pressed,
there is no spark at pilot
spots or streaks and, in extreme cases,
holes). Have these items replaced im
-
mediately by a qualified service person.
2. Remove vent cap and shine a flashlight
into vent. Remove any foreign material.
3. Check for evidence of excessive con
-
densation. Continuous condensation can
cause corrosion of caps, pipes and fittings
and can be caused by having excessive
lateral runs, too many elbows or exterior
portions of the system being exposed to
cold weather.
4. Inspect joints to verify that no pipe section
or fitting has been disturbed and loos
