Shutting Off Fireplace
1. Turn control knob clockwise
to the OFF position.
2. Turn off all electric power to the ap-
pliance if service is to be performed.
Shutting Off Burner Only (pilot
stays lit)
Turn control knob clockwise to
the PILOT position.
The thermostatic control used on this fire-
place differs from standard thermostats.
Standard thermostats simply turn on and
off the burner. The thermostat used on
this fireplace senses the room tempera-
ture. 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 mea-
sures the temperature of air near the fire-
place cabinet. This may not always agree
with room temperature (depending on
housing construction, installation location,
room size, open air temperatures, etc.).
Frequent use of your fireplace will let you
determine your own comfort levels.

INSPECTING
BURNER
Thermocouple
Pilot Burner
Figure 30 - Correct Pilot Flame Pattern
Figure 31 - Incorrect Pilot Flame Pattern
Check pilot flame pattern and burner flame
pattern often.
PILOT FLAME PATTERN
Figure 30 shows a correct pilot flame pattern.
Figure 31 shows an incorrect pilot flame
pattern. The incorrect pilot flame is not prop-
erly heating the thermocouple. This will cause
the thermocouple to cool. When the thermo-
couple cools, the fireplace will shut down.
If pilot flame pattern is incorrect, as shown
in Figure 31
turn fireplace off (see To Turn Off Gas to
Appliance)
see Troubleshooting, pages 19 through 21
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.

BURNER FLAME PATTERN
Figure 32 shows a correct burner flame
pattern. Figure 33 shows an incorrect burner
flame pattern. The incorrect burner flame
pattern shows sporadic, irregular flame tip-
ping. 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 approxi-
mately one hour until the log cures.
If burner flame pattern is incorrect, as shown
in Figure 33
turn fireplace off (see To Turn Off Gas to
Appliance)
