Failure to inspect and maintain heater may lead to improper 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 thermocouple.
Figure 58
If not, contact dealer for service.
2. Turn master switch on the command center to the “OFF” position and gas shutoff to "OFF" to turn
gas off to heater.
See step “To Turn Off Gas”, Page 27.
Allow heater to cool for 15 minutes. Remove
glass.

3. Carefully remove log set. If logs are severely deteriorated, replace. Check logs for sooting. A small
amount of soot along bottom is normal. If excessive sooting is found, heater must be adjusted.
Contact dealer where you bought heater.
4. Remove rock wool. Clean burner and burner ports.
Figure 59
5. Replace log set and rock wool according to instructions on Pages 23-25. Replace glass door. Make
sure gasket along perimeter of glass contacts face of firebox and forms an airtight seal. Realign if
airtight seal is not formed. Replace door glass and glass frame if damaged.
6. Inspect area around controls. Clean if necessary. Check gas control valve and all gas lines. If dam-
aged, 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 opera-
tion.
