OPERATING FIREPLACE

Continued

2.The receiver continuously receives signals from the hand-held remote to control the room temperature. If the hand-held remote is misplaced, obstructed, or for any reason cannot transmit to the receiver, the receiver will shut off the fireplace after 8 minutes.

Key Pad Lock Feature

This feature allows the user to lock/unlock the keypad on the hand-held remote in the MANU or AUTO mode to prevent inadvertent operation (i.e. children operating the hand-held remote control, etc.). The keypad is locked in either on or off. Press the POWER and LOCK buttons together to turn the unit on or off.

OPTIONAL GWMT1 WALL

MOUNTED THERMOSTAT

Make sure the heater switch is on AUTO and set the temperature adjustment on wall thermostat to the desired setting. The thermostat has been electronically calibrated at the factory and requires no adjustment or leveling.

Upon installation, the thermostat must be al- lowed to stabilize at room temperature for a minimum of 30 minutes for proper operation. See installation instructions on page 19.

OPTIONAL GWMS2 WALL

MOUNTED SWITCH

Make sure the heater switch is on AUTO. This wall switch works just like the conventional light switch. Flip the switch up for on and down for off.

Note: Make sure that this switch is not in a posi- tion to be mistaken for a light switch. This may result in the fireplace being inadvertently turned on without the proper precautions being taken. See installation instructions on page 19.

OPERATING

BLOWER

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 51 shows a correct pilot flame pattern. Figure 52 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the ther- mocouple. 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 52

•turn fireplace off (see To Turn Off Gas to Appli- ance, page 23 for Thermostat-Controlled Mod- els or page 25 for Remote-Ready Models)

•see Troubleshooting, page 30

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.
