seconds after lighting pilot. After 30
seconds, release control knob. If control
knob does not pop up when released,

to desired heating level. The main burner
should light. Set control knob to any heat
level between HI and LO.
CAUTION: Do not try to ad-
just heating levels by using the
equipment shutoff valve.
THERMOSTAT CONTROL OPERATION
The thermostatic control used on these models
differ from standard thermostats. Standard ther-
mostats simply turn the burner on and off. 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 temperature. The control knob
can be set to any comfort level between HI and LO.
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.
