BLOWER
OPERATION
WARNING: This fireplace has a
three-prong, grounded electrical
plug. This plug helps protect you
against electrical shock. Only con-
nect plug to a properly grounded,
three-prong receptacle. Do not cut
or remove the grounding prong
from this plug.
Locate the blower switch by opening lower
louver on fireplace. Blower switch is located at
lower left inside louver door.
This thermostat-controlled blower has a vari-
able speed control with an ON/OFF switch. The
blower will start when the thermostat senses a
sufficient increase in firebox temperature.
Note:
It is safe to operate fireplace with blower
turned off. However, the blower helps distribute
heated air from the fireplace.
Note:
Periodically check the louvers of the
firebox and remove any dust, dirt or other
obstructions.

Check pilot flame pattern and burner flame pat-
terns often.
PILOT FLAME PATTERN
Figure 29 shows a correct pilot flame pattern. Figure
30 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 30
• turn fireplace off (see To Turn Off Gas to Ap-
pliance, page 18)
• see Troubleshooting, page 22
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.

FRONT BURNER FLAME PATTERN
Figure 31 shows correct front burner flame pat-
tern. Figure 32 shows incorrect front burner flame
pattern. The incorrect burner flame pattern shows
yellow tipping at top of blue flame.
WARNING: If front burner
flame pattern shows yellow tip-
ping, your fireplace could pro-
duce increased levels of carbon
monoxide. Follow instructions at
bottom of this page. Yellow flame
on rear burner is normal.
