be set to any heat level between HI

The thermostatic control used on
these models differs from standard
thermostats. Standard thermostats
simply turn on and off the burner.
The thermostat used on this heater
senses the room temperature. The
thermostat adjusts the amount
of gas flow to the burner.
CAUTION: Do not try to
adjust heating levels by using
the equipment shutoff valve.
