Note:
You may be running this fireplace
for the first time after hooking up to gas
supply. If so, the control knob may need to
be pressed in for 30 seconds or more. This
will allow air to bleed from the gas system.
• If control knob does not pop out when re-
leased, contact a qualified service person
or gas supplier for repairs.

onds after lighting pilot. After 30 seconds,

tem to reset before lighting pilot again.

THERMOSTAT CONTROL
OPERATION
The thermostat used on this fireplace senses the
room temperature. At times the room may ex-
ceed the set temperature. If so, the burner will
shut off. The burner will cycle back on when room
temperature drops below the set temperature.
The control knob can be set to any heat level
between HI and LO.
Note:
The thermostat sensing bulb measures
the air near the fireplace cabinet. This may not
always agree with room temperature (depend-
ing on housing construction, installation loca-
tion, room size, open air temperatures, etc.).
Frequent use of your fireplace will let you de-
termine your own comfort levels.
