Manual Mode

1.Press the POWER and LOCK buttons together to turn on the hand-held remote control.

2.Press the MANU button to turn on the fireplace.

3.Press the POWER and LOCK buttons together to turn off the fireplace.

Auto (Thermostatic) Mode

1.Press the POWER and LOCK buttons together to turn on the hand-held remote control.

2.Press AUTO button to select this mode.

3.Set the desired room temperature by pressing the TEMP + or - buttons.

4.Press the POWER and LOCK buttons together to turn off the fireplace

Note: Do not leave the hand-held remote in the AUTO mode close to the fireplace. The radiant heat from the fireplace will turn off the fireplace. Ideally, place the hand-held remote in the center of the room facing towards the fireplace.

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

Auto Shutoff Feature

1.If the average room temperature exceeds 82 degrees Fahr- enheit (28 degrees Centigrade), the hand-held remote con- trol 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 re- mote 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 patterns 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 touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down.

•see Troubleshooting, pages 24 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.
