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 comfort setting will vary by
household depending 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.
MANUAL LIGHTING
PROCEDURE
INSPECTING
BURNERS
Check pilot flame pattern and burner flame
patterns often.
PILOT FLAME PATTERN
Figure 34 shows a correct pilot flame pattern.
Figure 35 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 35
• turn heater off (see To Turn Off Gas to
Appliance, page 18 [manually-controlled
models] or page 19 [thermostat-con-
trolled models])
• see Troubleshooting, pages 21 through 23
