Check pilot flame pattern and burner flame
pattern often.
PILOT FLAME PATTERN
Figure 31 shows a correct pilot flame pattern.
Figure 32 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
thermocouple cools, the fireplace will shut
down.
If pilot flame pattern is incorrect, as shown
in Figure 32
• turn fireplace off (see To Turn Off Gas to
Appliance)
• see Troubleshooting, pages 19 through 21
TO TURN OFF GAS
TO APPLIANCE
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 er will cycle back on when room tem-
perature 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.

BURNER FLAME PATTERN
Figure 33 shows a correct burner flame
pattern. Figure 34 shows an incorrect burner
flame pattern. The incorrect burner flame
pattern shows sporadic, irregular flame tip-
ping. It also shows the flame consistently
higher than one inch above the log.
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 34
• turn fireplace off (see To Turn Off Gas to
Appliance)
• see Troubleshooting, pages 19 through 21
