THERMOSTAT CONTROL

OPERATION
The thermostatic control used on these models differs from stan-
dard 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 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 always agree with
room temperature (depending on housing construction, instal-
lation location, room size, open air temperatures, etc.). Fre-
quent use of your heater will let you determine your own
comfort levels.
