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
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

vENTING SYSTEM
Conduct annual inspection of the venting system
following these guidelines:
1. Check areas of venting system that are exposed
to the weather for corrosion (rust spots or streaks
and, in extreme cases, holes). Have these items
replaced immediately by a qualified service
person.
2. Remove the vent cap and shine a flashlight
into the vent. Remove any foreign material.
3. Check for evidence of excessive condensation.
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 loosened. Check mechani-
cal supports such as wall straps for rigidity.
