OPERATING FIREPLACE

Continued

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.

INSPECTING BURNERS

Check pilot flame pattern and burner flame pat- terns often.

PILOT FLAME PATTERN

Figure 47 shows a correct pilot flame pattern. Figure 48 shows an incorrect pilot flame pattern. The incor- rect pilot flame is not touching 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 48

turn fireplace off (see To Turn Off Gas to Appli- ance, page 25 for Thermostat-Controlled Mod- els or page 27 for Remote-Ready Models)

see Troubleshooting, page 31

Note: The correct 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 49 shows a correct burner flame pattern. Figure 50 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 50

turn fireplace off (see To Turn Off Gas to Ap- pliance, page 25 for Thermostat-Controlled Models or page 27 for Remote-Ready Models)
