CLEANING AND MAINTENANCE

YEARLY SERVICE PROCEDURE

Failure to inspect and maintain heater may lead to im-
proper combustion and a potentially dangerous situation.
A qualified technician should do the following once a year.
1. Check pilot flame. Flame should touch approximately
3/8" of the top of thermopile and touch top of thermo-
couple. Figure 34 If not, contact dealer for service.
2. Turn gas control knob to "OFF" position to shut off gas to
heater. See step "To Turn Off Gas", Page 24. Let heater
cool for 15 minutes. Remove faceplate (see instructions
included with face plate) and glass. Page 18.
3. Carefully remove log set. If logs are severely deteri-
orated, replace logs. Check logs for sooting. A small
amount of soot along bottom of logs is normal. If exces-
sive sooting is found, heater must be adjusted. Contact
dealer where you bought heater.
