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 Centigrade),
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.

Check pilot flame pattern and burner flame pat-
terns often.
pILOT FLAME pATTERN
Figure 33 shows a correct pilot flame pattern.
Figure 34, page 23, 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 34, page 23
• turn heater off (see To Turn Off Gas to Appli-
ance, page 20)
• see Troubleshooting, page 25
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.
