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.
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 exceeds
82 degrees Fahrenheit (28 degrees Centi
-
grade), the hand-held remote control 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
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 22 shows a correct pilot flame pattern.
Figure 23 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 23
• turn heater off (see To Turn Off Gas to Appli
-
ance, page 17)
• see Troubleshooting
, page 22
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.
