OPERATING
BLOWER
This heater has a thermostatic blower that will
automatically turn ON or OFF.
Note:
Your heater and thermostat blower will
not turn on and off at the same time. The
heater may run for several minutes before the
blower turns on. After the heater modulates to
the pilot position, the blower will continue to
run. The blower will shut off after the heater
cabinet temperature decreases.
Note:
It is safe to operate heater with blower
turned off. However, the blower helps distrib-
ute heated air from the heater.

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.
Note:
The thermostat sensing bulb measures
the temperature of air near the heater cabinet.
This may not always agree with room tem-
perature (depending on housing construction,
installation location, room size, open air tem-
peratures, etc.). Frequent use of your heater will
let you determine your own comfort levels.
