THERMOSTAT CONTROL

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 de-
pending 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.
