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 surround
the top of the sensor. Figure 46. If not, contact dealer for service.
. Turn master switch to "OFF" position and gas shut off to shut off gas to heater. See step "To Turn
Off Gas", Page 25. Let heater cool for 15 minutes. Remove faceplate (see instructions included
with face plate) and glass. Pages 37 & 38
3. Carefully remove log set. If logs are severely deteriorated, replace logs. Check logs for sooting. A
small amount of soot along bottom of logs is normal. If excessive sooting is found, heater must be
adjusted. Contact dealer where you bought heater.
4. Clean burner and burner ports. Make sure burner ports are not obstructed with debris.
5. Replace log set and rock wool per instructions on Pages 0-. 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 opera-
tion.
