OPERATING FIREPLACE
INSERT
Continued
Locate the 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, the blower will operate con-
stantly. In the OFF position, the blower will not operate. In the
AUTO position, the blower will start when the thermostat
senses a sufficient increase in firebox temperature.

OPERATION
INSPECTING BURNERS
Check pilot flame pattern and burner flame patterns often.
PILOT FLAME PATTERN
Figure 37 shows a correct pilot flame pattern. Figure 38 shows an
incorrect pilot flame pattern. The incorrect pilot flame is not
properly heating the thermocouple. When the thermocouple cools,
the heater will shut down.
If pilot flame pattern is incorrect, as shown in Figure 38
• turn heater off (see To Turn Off Gas to Appliance, page 17)
• see Troubleshooting, pages 21 through 23
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.

IMPORTANT:
This remote control has been specially en-
gineered to take an air temperature sample every 5.5 min-
utes in the auto mode. It will not respond immediately to
the temperature setting being turned up or down.
IMPORTANT:
The hand-held remote control unit must
be near the heater. Do not keep the hand-held remote
control unit too close to the heater. The thermostat on
the hand-held remote control unit will heat up too quickly
and turn the heater off.

To turn the burner off, press the AUTO/ON/OFF button
until OFF lights. The pilot will remain lit.
IMPORTANT:
To turn the pilot off, manually turn the con-
trol knob on the heater to the OFF position.

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 the blower turns on. After the heater modulates
to the pilot position, the blower will continue to run. The blower
will shut off after the firebox temperature decreases.
Note:
It is safe to operate fireplace insert with blower turned
off. However, the blower helps distribute heated air from the
fireplace insert.
