5. Turn control knob counterclockwise
to the PILOT position. Press in control knob
for five (5) seconds (see Figure 29).
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 up when re-
leased, contact a qualified service person
or gas supplier for repairs.

ton until pilot lights.
Note: If pilot does not stay lit, refer to
Troubleshooting, pages 23 through 26. Also
contact a qualified service person or gas
supplier for repairs. Until repairs are made,
light pilot with match. To light pilot with
match, see Manual Lighting Procedure.
7. Keep control knob pressed in for 30 sec-
onds after lighting pilot. After 30 seconds,
release control knob.
Note: If pilot goes out, repeat steps 3
through 7. This fireplace has a safety inter-
lock system. Wait one (1) minute before
lighting pilot again.
8. Turn control knob counterclockwise
to desired heating level. The main
burner should light. Set control knob to any
heat level between HI and LO.
CAUTION: Do not try to ad-
just heating levels by using the

THERMOSTAT
CONTROL OPERATION
The thermostatic control used on this fireplace dif-
fers from standard thermostats. Standard thermo-
stats simply turn on and off the burner. The ther-
mostat used on this fireplace senses the room tem-
perature. The thermostat adjusts the amount of
gas flow to the burner. This increases or decreases
the burner flame height. At times the room may
exceed 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 temperature of air near the fireplace cabi-
net. This may not always agree with room tem-
perature (depending on housing construction,
installation location, room size, open air tem-
peratures, etc.). Frequent use of your fireplace
will let you determine your own comfort levels.
