THERMOSTAT
CONTROL OPERATION
The thermostatic control used on these
models differs from standard thermo-
stats. Standard thermostats simply turn
on and off the burner. The thermostat
used on this heater senses the room tem-
perature. 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 temperature drops below the
set temperature. The control knob can be
set to any heat level between HI and LO.
Note: The thermostat sensing bulb mea-
sures the temperature of air near the
heater cabinet. This may not always agree
with room temperature (depending on
housing construction, installation loca-
tion, room size, open air temperatures,
etc.). Frequent use of your heater will let
you determine your own comfort levels.
