The thermostatic control used on this model
differs from standard thermostats. You set
standard thermostats to a specific tempera-
ture such as 72° F. The control of this heater
establishes a "comfort level". In order for the
thermostat to operate effectively, the heater
should be the main source of heat in the
room. Follow the instructions for lighting the
heater on page 16. When the room reaches
the desired comfort level, rotate the control
knob clockwise slowly until the main burner
turns off and the pilot remains on (this position
on the knob will change depending on room
temperature).
Turn the knob counter-clockwise slowly until
the main burner reignites. Note the position
of the control knob by the numbers printed
on the knob. Leave the knob in this position.

As the room temperature increases, the main
burner will turn off and the pilot will remain
on. When the room temperature cools, the
heater's main burner will come back on. If left
at this set point the thermostat will turn the
main burner on or off as needed to maintain
the room temperature at the desired comfort
level.
Note: The thermostat sensing bulb reacts
to the temperature depending on house's
construction.
CAUTION: Do not try to ad-
just heating levels by using the
