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.

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 34 shows a correct pilot flame pattern. Figure 35 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermocouple. When the thermocouple cools, the heater will shut down.

If pilot flame pattern is incorrect, as shown in Figure 35

Safety Features

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

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.

BURNER PRIMARY AIR HOLES

Air is drawn into the burner through the holes in the fitting at the burner entrance. These holes may become blocked with dust or lint. Periodically inspect these holes for any blockage and clean if needed. Blocked air holes will create soot.

MAIN BURNER

Periodically inspect all burner flame holes with the heater running. All slotted burner flame holes should be open with yellow flame present. All round burner flame holes should be open with a small blue flame present. Some burner flame holes may become blocked by debris or rust, with no flame present. If so, turn off heater and let cool. Remove blockage. Blocked burner flame holes will create soot.
