THERMOSTAT CONTROL

OPERATION

The thermostat control knob can be set to
any comfort level between Hi and Lo. The
thermostat will gradually modulate the heat
output and flame height from higher to
lower settings, or pilot, in order to maintain
the comfort level you select. The ideal com-
fort setting will vary by household depend-
ing upon the amount of space to be heated,
the output of the central heating system, etc.

Note:

Selecting the Hi setting with the

control knob will cause the burners to
remain fully on, without modulating down
in most cases.

INSPECTING
BURNERS

Check pilot flame pattern and burner flame
patterns often.

PILOT FLAME PATTERN

Figure 19 shows a correct pilot flame pat-
tern. Figure 20 shows an incorrect pilot
flame pattern. (

Note:

Appearance of pilot

assembly may vary by model). The incor-
rect pilot flame is not touching the thermo-
couple. This will cause the thermocouple to
cool. When the thermocouple cools, the heater
will shut down.

If pilot flame pattern is incorrect, as shown
in Figure 20

• turn heater off (see To Turn Off Gas to

Appliance)

• see Troubleshooting, pages 14 through 16
