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°
Fahrenheit (28° 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.

INSPECTING BURNERS

Check pilot flame pattern and burner flame pat-
terns often.
PILOT FLAME PATTERN
Figure 33 shows a correct pilot flame pattern.
Figure 34 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 34
• turn heater off [see To Turn Off Gas to Appli-
ance, page 18 (Manually-Controlled Models),
or page 20 (Remote-Ready Models)]
• see Troubleshooting, page 24
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.

BURNER PRIMARY AIR HOLES
Air is drawn into the burner through the holes in
the fitting at the burner entrance. These holes may
become blocked with dust or lint. Periodically
inspect these holes for any blockage and clean if
needed. Blocked air holes will create soot.
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 will create soot.
