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 52
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 or decorative glass. If logs
have 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.

5. Replace log set and ember according to instructions
on Pages 21-25. Replace decorative glass according
to instructions on Page 24. 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 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.
