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

If so, the control knob may need to
be pressed in for 30 seconds or less.
This will allow air to bleed from the
gas system.

With control knob pressed in, press
and release ignitor button. This will
light pilot. The pilot is attached to the
front burner. If needed, keep press-
ing ignitor button until pilot lights.

tact a qualified service person or gas
supplier for repairs. Until repairs are
made, light pilot with match. To light
pilot with match, see Manual Light-
ing Procedure.
