Thermostat models have a safety interlock
system. Wait one (1) minute before lighting
pilot again.

THERMOSTAT
CONTROL OPERATION
Thermostat models only
The thermostatic control used on these models
differs from standard thermostats. Standard ther-
mostats 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.
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, installation
location, room size, open air temperatures, etc.).
Frequent use of your heater will let you determine
your own comfort levels.
