TO TURN OFF GAS TO APPLIANCE
Shutting Off Heater
1. Turn control knob clockwise Clockwise
to the OFF position.
2.Turn off all electric power to the appliance if service is to be performed.
Shutting Off Burner Only (pilot stays lit)
Turn control knob clockwise Clockwise
to the PILOT position.
THERMOSTAT CONTROL
OPERATION
The thermostatic control used on this heater differs from stan- dard 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 decreases 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.
The control knob can be set to any heat level between HI and LO.
Note: The thermostat sensing bulb measures the temperature of air near the heater cabinet. This may not always agree with room temperature (depending on housing construction, installation location, room size, open air temperatures, etc.). Frequent use of your heater will let you determine your own comfort levels.

BURNER FLAME PATTERN
Figure 28 shows a correct burner flame pattern. Figure 29 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 produce increased levels of carbon monoxide. If burner flame pattern shows yellow tipping, follow instructions at bottom of this page.
NOTICE: Do not mistake orange flames with yellow tipping. Dirt or other fine particles enter the heater and burn causing brief patches of orange flame.
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 pilot 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 Instructions, page 14.
5.Replace front panel.
INSPECTING BURNER
Check pilot flame pattern and burner flame pattern often.
If burner flame pattern is incorrect, as shown in Figure 29
•turn heater off (see To Turn Off Gas to Appliance)
•see Troubleshooting, pages 17 through 19

PILOT FLAME PATTERN
Figure 26 shows a correct pilot flame pattern. Figure 27 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 27
•turn heater off (see To Turn Off Gas to Appliance)
•see Troubleshooting, pages 17 through 19
