OPERATING FIREPLACE

TO TURN OFF GAS
TO APPLIANCE
Shutting Off Fireplace
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.
INSPECTING BURNER
Check pilot flame pattern and burner flame pattern often.
PILOT FLAME PATTERN
Figure 32 shows a correct pilot flame pattern. Figure 33 shows an incorrect pilot flame pattern. The incorrect pilot flame is not properly heating the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the fireplace will shut down.
If pilot flame pattern is incorrect, as shown in Figure 33
•turn fireplace off (see To Turn Off Gas to Appliance)
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 fireplace differs from standard thermostats. Standard thermostats simply turn on and off the burner. The thermostat used on this fireplace 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 heater 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 fireplace cabinet. This may not always agree with room temperature (depending on housing construction, instal- lation location, room size, open air temperatures, etc.). Fre- quent use of your fireplace will let you determine your own comfort levels.
MANUAL LIGHTING
PROCEDURE
1.Follow steps 1 through 5 under Lighting Instructions, page 17.
2.With control knob pressed in, strike match. Hold match to pilot until pilot lights.
3.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 17.
• see Troubleshooting, pages 20 through 22
Note: The pilot flame on natural gas units will have a slight curve, but flame should be blue and have no yellow or orange color.

BURNER FLAME PATTERN
Figure 34 shows a correct burner flame pattern. Figure 35 shows an incorrect burner flame pattern. The incorrect burner flame pattern shows sporadic, irregular flame tipping. The flame should not be dark or have an orange/reddish tinge.
Note: When using the fireplace the first time, the flame will be orange for approximately one hour until the log cures.
If burner flame pattern is incorrect, as shown in Figure 35
•turn fireplace off (see To Turn Off Gas to Appliance)
