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.

THERMOSTAT CONTROL
OPERATION
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
temperature drops below the set temperature.
The control knob can be set to any heat level
between 1 and 5. Selecting the 5 setting will
cause the burner to remain fully on without
modulating down in most cases.
