Cleaning and

Maintenance

Continued

pilot and burners

Remove ember material before cleaning burners and replace when cleaning is complete.

Burner and controls should be cleaned with compressed air to remove dust, dirt, or lint.

Use a vacuum cleaner or small, soft bristled brush to remove excess dust, dirt, or lint.

logs

If you remove logs for cleaning, refer to Installing Logs, Lava Rock, and Glowing Embers, page 20, to properly replace logs.

Use a vacuum cleaner to remove any carbon buildup on logs.

Replace log(s) if broken. See Replacement Parts on page 28.

Replace ember material periodically as needed. See Replacement Parts on page 28.

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. Re- move 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 mechanical supports such as wall straps for rigidity.

Troubleshooting

WARNING: Turn off heater and let cool before ser- vicing. Only a qualified service person should service and repair heater.

Note: All troubleshooting items are listed in order of operation.

CAUTION: Never use a wire, needle, or similar object

to clean pilot. This can damage pilot unit.
