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 reaches
a range of 82° F (28° C) to 92° F (33° C),
the hand-held remote control will perform a
safety override and shut the fireplace off. This
feature is not available in MANU mode.
2. The receiver continuously receives sig-
nals 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. This will
occur in 8 or more minutes depending
upon location of remote transmitter and
strength of batteries.
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 op-
eration (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
patterns often.
PILOT FLAME PATTERN
Figure 29 shows a correct pilot flame pattern.
Figure 30 shows an incorrect pilot flame pat
-
tern. The incorrect pilot flame is not touching
the thermocouple. This will cause the thermo-
couple to cool. When the thermocouple cools,
the heater will shut down.
If pilot flame pattern is incorrect, as shown
in Figure 30
• turn heater off (see
To Turn Off Gas to Ap-
pliance
, page 21
