Failure to inspect and maintain heater may lead to improper
combustion and a potentially dangerous situation. A quali-
fied 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 41.
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 27.
Allow
heater to cool for 15 minutes. Remove faceplate (see
instructions included with face plate) and glass.

3. Carefully remove log set. If logs are severely dete-
riorated, 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.
4. Clean burner and burner ports.
Figure 42
5. Replace log set and rock wool per instructions on Pages
19-21. Replace glass. Make sure gasket along perimeter
of glass contacts face of firebox and forms an airtight
seal. Realign if airtight seal is not formed. Replace glass
and glass frame if damaged.
6. Inspect area behind face plate. Clean if necessary.
Check gas control valve and all gas lines. If damaged,
do not use heater. Contact your dealer.
7. Start pilot and turn on main burner. Flames should be
orange/yellow and not touch top of firebox. If pilot or
main burners do not burn correctly, contact your dealer
for service. Monitor blower operation.
