OPERATION

THERMOSTAT CONTROL OPERATION

The thermostatic control used on this model

differs from standard thermostats. Standard

thermostats simply turn the burner on and off.

The thermostat used on this heater senses the

room temperature. At times the room may ex-

ceed the set temperature. If so, the burner will

shut off. The burner will cycle back on when

room temperature drops below the set tem-

perature. The control knob can be set to any

comfort level between HIGH (5) and LOW (1).

to the

OFF position.

Note: If pilot goes out, repeat steps 2

through 6. This heater has a safety inter-

lock system. Wait one (1) minute before
