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, 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 the MANU
mode.
2. The receiver continuously receives sig-
nals from the hand-held remote to control
the room temperature. If the hand-held re-
mote 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

OPTIONAL BLOWER
OPERATION
Locate blower switch by opening lower louver
on fireplace insert. Blower switch is located at
lower left inside louver door.
This thermostat-controlled blower has three
settings: ON, OFF and AUTO. In the ON
position, blower will operate constantly. In
the OFF position, blower will not operate.
In the AUTO position, blower will start when
thermostat senses a sufficient increase in
firebox temperature.
Note: Your gas logs and thermostat blower
will not turn on and off at the same time. The
fireplace insert may run for several minutes
before blower turns on. After heater modulates
to pilot position, blower will continue to run.
Blower will shut off after firebox temperature
decreases.
Note: It is safe to operate fireplace insert with
blower turned off. However, blower helps dis-
tribute heated air from fireplace insert.
Check pilot flame pattern and burner flame
patterns often.
PILOT FLAME PATTERN
Figure 36 shows a correct pilot flame pattern.
Figure 37 shows an incorrect pilot flame pat-
tern. The incorrect pilot flame is not properly
heating the thermocouple. When the thermo-
couple cools, the heater will shut down.
If pilot flame pattern is incorrect, as shown
in Figure 37
• turn heater off (see To Turn Off Gas to Ap-
pliance, 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.
