OPERATING FIREPLACE

OPERATING
BLOWER
This blower has three settings: ON, OFF, and AUTO. In the ON position, the blower will op- erate constantly. In the OFF position, 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 distrib- ute heated air from the fireplace.

BURNER FLAME PATTERN
Figure 34 shows a correct burner flame pattern. Figure 35 shows an incorrect burner flame pat- tern. 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 Ap- pliance, page 20)
•see Troubleshooting, pages 23 through 26
PILOT FLAME PATTERN
Figure 32 shows a correct pilot flame pattern. Fig- ure 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 fire- place will shut down.
If pilot flame pattern is incorrect, as shown in Fig- ure 33
•turn fireplace off (see To Turn Off Gas to Ap- pliance, page 20)
•see Troubleshooting, pages 23 through 26 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.
