OPERATING
BLOWER
This blower has three settings: ON, OFF, and
AUTO. In the ON position, the blower will op-
erate constantly. 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.
Note:
Your fireplace and thermostat blower
will not turn on and off at the same time. The
fireplace 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 with blower
turned off. However, the blower helps distrib-
ute heated air from the fireplace.

INSPECTING BURNERS
Check pilot flame pattern and burner flame pat-
terns often.
PILOT FLAME PATTERN
Figure 47 shows a correct pilot flame pattern. Figure
48 shows an incorrect pilot flame pattern. The incor-
rect pilot flame is not touching the thermocouple.
This will cause the thermocouple to cool. When the
thermocouple cools, the fireplace will shut down.
If pilot flame pattern is incorrect, as shown in
Figure 48
•
turn fireplace off (see To Turn Off Gas to Appli-
ance, page 25 for Thermostat-Controlled Mod-
els or page 27 for Remote-Ready Models)
• see Troubleshooting, page 31
Note: The correct pilot flame on natural gas units
will have a slight curve, but flame should be blue
and have no yellow or orange color.

BURNER FLAME PATTERN
Figure 49 shows a correct burner flame pattern.
Figure 50 shows an incorrect burner flame pat-
tern. The incorrect burner flame pattern shows
sporadic, irregular flame tipping. The flame should
not be dark or have an orange/reddish tinge.
Note:
When using the fireplace the first time, the
flame will be orange for approximately one hour
until the log cures.
If burner flame pattern is incorrect, as shown in
Figure 50
• turn fireplace off (see To Turn Off Gas to Ap-
pliance, page 25 for Thermostat-Controlled
Models or page 27 for Remote-Ready Models)
