Note: Do not hold the hand-held remote for a long time. Body temperature will affect its operation in the AUTO mode.

Safety Features

When away from home for an extended period of time or as a child safety feature to prevent accidental ignition of the fireplace, the receiver ON/OFF/REMOTE switch should be in the OFF position.

Auto Shutoff Feature

1. If the average room temperature exceeds

82 degrees Fahrenheit (28 degrees Centi- grade), the hand-held remote control will perform a safety override and shut the fireplace off. This feature is not available in the MANU mode.

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.

Inspecting Burners

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

PILOT FLAME PATTERN

Figure 36 shows a correct pilot flame pattern. Figure 37, shows an incorrect pilot flame pattern. The incorrect pilot flame is not properly heating the thermocouple. When the thermocouple cools, the heater will shut down. If pilot flame pattern is incorrect, as shown in Figure 37

turn heater off (see To Turn Off Gas to Appli- ance, page 20)

see Troubleshooting, page 24

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.
