THERMOSTAT

CONTROL OPERATION

The thermostatic control used on this
heater differs from standard thermostats.
Standard thermostats simply turn on and
off the burner. The thermostat used on
this heater senses the room temperature.
The thermostat adjusts the amount of gas
flow to the burner. This increases or de-
creases 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
heater cabinet. This may not always agree
with room temperature (depending on
housing construction, installation loca-
tion, room size, open air temperatures,
etc.). Frequent use of your heater will let
you determine your own comfort levels.

MANUAL LIGHTING

PROCEDURE

1.

Remove front panel (see Figure 2,

match. Hold match to pilot until pi-
lot lights.

4.

Keep control knob pressed in for 30
seconds after lighting pilot. After 30
seconds, release control knob. Now

INSPECTING
BURNER

Figure 24 - Incorrect Pilot Flame Pattern

Check pilot flame pattern and burner flame
pattern often.

PILOT FLAME PATTERN

Figure 23 shows a correct pilot flame pattern.
Figure 24 shows an incorrect pilot flame
pattern. The incorrect pilot flame is not touch-
ing the thermocouple. This will cause the
thermocouple to cool. When the thermo-
couple cools, the heater will shut down.

If pilot flame pattern is incorrect, as shown
in Figure 24

• turn heater off (see To Turn Off Gas to

Appliance, page 14)

• see Troubleshooting, pages 16 through 18

BURNER FLAME PATTERN

Figure 25 shows a correct burner flame
pattern. Figure 26 shows an incorrect burner
flame pattern. The incorrect burner flame
pattern shows yellow tipping of the flame. It
also shows the flame higher than one inch
above the log.

Note:

 When using the heater the first time,

the flame will be yellow for approximately
one hour until the log cures.

NOTICE: Do not mistake orange
flames with yellow tipping. Dirt
or other fine particles enter the
heater and burn causing brief
patches of orange flame.

 WARNING: If yellow tipping

occurs, your heater could pro-
duce increased levels of carbon
monoxide. If burner flame pat-
tern shows yellow tipping, follow
instructions, bottom of this page.

If burner flame pattern is incorrect, as shown
in Figure 26

• turn heater off (see To Turn Off Gas to

Appliance, page 14)

• see Troubleshooting, pages 16 through 18
