FRONT BURNER FLAME PATTERN

Figure 36 shows correct front burner flame pattern. Figure 37 shows

incorrect front burner flame pattern. The incorrect burner flame

pattern shows yellow tipping at top of blue flame.

WARNING: If yellow tipping occurs, your heater

could produce increased levels of carbon monoxide.

If front burner flame pattern shows yellow tipping,

follow instructions at bottom of this page. Yellow

flame on rear burner is normal.

NOTICE: Do not mistake orange flames with yellow

tipping. Dirt or other fine particles are burned by

heater, causing brief patches of orange flame.

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

• turn heater off (see To Turn Off Gas to Appliance, page 17 [Ther-

mostat-Controlled Models], page 19 [Manually-Controlled

Models], or page 20 [Remote-Ready Models])

• see Troubleshooting, pages 24 through 26

INSPECTING BURNERS

Check pilot flame pattern and burner flame patterns often.

PILOT FLAME PATTERN

Figure 35 shows a correct pilot flame pattern. Figure 36 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.

If pilot flame pattern is incorrect, as shown in Figure 36

• turn heater off (see To Turn Off Gas to Appliance, page 17 [Ther-

mostat-Controlled Models], page 19 [Manually-Controlled

Models], or page 20 [Remote-Ready Models])

• 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.

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.

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.
