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.
