THERMOSTAT CONTROL
OPERATION
The thermostat control knob can be set to any
comfort level between HI and LO. The ther-
mostat 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 burner to remain fully on,
without modulating down in most cases.
