TO TURN OFF GAS

TO APPLIANCE

Shutting Off Heater When Manually Lit Set manual ignition bypass switch on control pan- el to OFF (automatic ignition position). This will cause the controls to shut down the fireplace.

OPTIONAL BLOWER

OPERATION

Locate the blower switch by opening lower louver on fireplace. Blower switch is located at lower left inside louver door.

Note: It is safe to operate fireplace with blower turned off. However, the blower helps distribute heated air from the fireplace.

Follow installation instructions included with the blower accessory.

OPERATING

FAN

This blower has three settings: ON, OFF, and AUTO. In the ON position, the blower will oper- ate 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 distribute heated air from the fireplace.

INSPECTING BURNERS

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

PILOT FLAME PATTERN

Figure 41 shows a correct pilot flame pattern. Figure 42 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 42

turn heater off (see To Turn Off Gas to Appli- ance, page 23 or column 1)

see Troubleshooting, page 27

Note: The pilot flame on natural gas units will have a slight curve, but the flame should be blue and have no yellow or orange color.
