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.

Inspecting Burners

Check pilot flame pattern and burner flame pat- terns 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 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 35

•turn fireplace off (see To Turn Off Gas to Ap- pliance, page 20 or 22, depending on your model.)

•see Troubleshooting, page 27

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

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 may create soot.

FRONT BURNER FLAME PATTERN

Figure 36 shows correct front burner flame pat- tern. Figure 38 shows incorrect front burner flame pattern. The incorrect burner flame pattern shows yellow tipping at top of blue flame.

If front burner flame pattern is incorrect, as shown in Figure 37

•turn fireplace off (see To Turn Off Gas to Ap- pliance, page 20 or 22, depending on your model.)

•see Troubleshooting, page 27
