THERMOSTAT
CONTROL
OPERATION
The thermostatic control used on this heater differs from standard thermostats. Standard thermostats simply turn on and off the burner. The thermostat used on this heater senses the room temperature. The thermostat adjusts the amount of gas flow to the burner. This increases or de- creases the burner flame height. At times the room may exceed the set temperature. If so, the burner will shut off. The burner will cycle back on when room temperature drops below the set temperature.
INSPECTING
BURNER
Check pilot flame pattern and burner flame pattern often.
PILOT FLAME PATTERN
Figure 25 shows a correct pilot flame pat- tern. Figure 26 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down.
If pilot flame pattern is incorrect, as shown in Figure 26
•turn heater off (see To Turn Off Gas to Appliance, page 14)
•seeTroubleshooting, pages 17 through 19
BURNER FLAME PATTERN
Figure 27 shows a correct burner flame pattern. Figure 28 shows an incorrect burner flame pattern. The incorrect burner flame pattern shows yellow tipping of the flame. It also shows the flame higher than one inch above the log.
Note: When using the heater the first time, the flame will be yellow for approximately one hour until the log cures.
WARNING: If yellow tipping occurs, your heater could pro- duce increased levels of carbon monoxide. If burner flame pat- tern shows yellow tipping, follow instructions at bottom of this page.
The control knob can be set to any heat level between HI and LO.

NOTICE: Do not mistake orange flames with yellow tipping. Dirt
Note: The thermostat sensing bulb mea- sures the temperature of air near the heater cabinet. This may not always agree with room temperature (depending on housing construction, installation loca- tion, room size, open air temperatures, etc.). Frequent use of your heater will let you determine your own comfort levels.
MANUAL LIGHTING
PROCEDURE
1.Remove front panel (see Figure 2, page 4).
2.Follow steps 1 through 5 under Lighting Instructions, page 14.
3.With control knob pressed in, strike match. Hold match to pilot until pi- lot lights.
4.Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob. Now follow step 8 under Lighting Instruc- tions, page 14.
5.Replace front panel.
