THERMOSTAT
CONTROL OPERATION
The thermostatic control used on this fire- place differs from standard thermostats. Standard thermostats simply turn on and off the burner. The thermostat used on this fireplace senses the room tempera- ture. 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 mea- sures the temperature of air near the fire- place 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 fireplace will let you determine your own comfort levels.
MANUAL LIGHTING
PROCEDURE
1.Follow steps 1 through 5 under Light- ing Instructions, page 17.
2.With control knob pressed in, strike match. Hold match to pilot until pi- lot lights.
3.Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob. Now follow step 8, page 17.
OPERATING BLOWER
This blower has three settings: ON, OFF, and AUTO. In the ON position, the blower will operate constantly. In the OFF posi- tion, the blower will not operate. In the AUTO position, the blower will start when the thermostat senses a sufficient increase in firebox temperature.
Note: Your fireplace and thermostat blower will not turn on and off at the same time. The fireplace may run for several minutes before the blower turns on. After the heater modulates to the pilot position, the blower will continue to run. The blower will shut off after the firebox temperature decreases.
Note: It is safe to operate fireplace with blower turned off. However, the blower helps distribute heated air from the fireplace.

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 prop- erly heating the thermocouple. This will cause the thermocouple to cool. When the thermo- couple 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)
•see Troubleshooting, pages 20 through 22
