INSPECTING
BURNERS
Check pilot flame pattern and burner flame patterns often.
PILOT FLAME PATTERN
Figure 33 shows a correct pilot flame pattern. Figure 34 shows an incorrect pilot flame pattern.
The incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to
cool. When the thermocouple cools, the fireplace will shut down.
Figure 33 - Correct Pilot Flame
Pattern
Figure 34 - Incorrect Pilot Flame
Pattern
If pilot flame pattern is incorrect, as shown in Figure 34
• turn fireplace off (see To Turn Off Gas to Appliance, page 23 [Thermostat-con-
trolled models} or page 25 [Manually-controlled models])
• see Troubleshooting, pages 28 through 31
Locate the blower switch by opening lower louver on fireplace. Blower switch is located at
lower left inside louver door.
Thermostat-controlled blowers have three settings: ON, OFF, and AUTO. In the ON
position, the blower will operate constantly. In the OFF position, the blower will not
operate. In the AUTO position, the blower will start when the thermostat senses a suffi-
cient increase in firebox temperature.
Note:
Your gas logs and thermostat blower will not turn on and off at the same time. The
fireplace may run for several minutes before the blower turns on. After the heater modu-
lates to the pilot position, the blower will continue to run. The blower will shut off after
the firebox temperature decreases.
Note:
It is safe to operate fireplace with blower turned off. However, the blower helps
distribute heated air from the fireplace.

This optional non-thermostat blower kit has a rotary dial which allows infinitely adjust-
able blower speed control. Follow installation instructions included with blower.
