THERMOSTAT
CONTROL OPERATION
Thermostat models only
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. 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 temper-
ature. The control knob can be set to any heat
level between 1 and 5. This adjusts the amount
of gas flow to the burner. This increases or
decreases the burner flame height.
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 location, room size,
open air temperatures, etc.). Frequent use of
your heater will let you determine your own
comfort levels.
