THERMOSTAT
CONTROL
OPERATION
OPERATING YOUR HEATER
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.
This increases or decreases the
burner flame height. At times the room
may exceed the set temperature. If so,
the burner will shut off. The burner
will cycle back on when room tem-
perature drops below the set
temperature. The control knob can be
set to any heat level between HI and
LO. Selecting the HI setting will cause
the burner to remain fully on without
modulating down in most cases.
NOTE: the thermostat sensing bulb
measures the temperature of air near
the heater cabinet. This may not al-
ways agree with room temperature
(depending on housing construction.
installation location, room size, open
air temperatures, etc.). frequent use of
your heater will let you determine
