a qualified service person or gas supplier for
repairs. Until repairs are made, light pilot with
match. To light pilot with match, see

to
desired heating level. The main burner should
light.

THERMOSTAT CONTROL
OPERATION
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. Selecting the 5 setting will cause the burner
to remain fully on without modulating down in
most cases.
