Shutting Off Heater

Shutting Off Burner Only (pilot stays lit)

THERMOSTAT

OPERATION

The thermostatic control used on these models

differs from standard thermostats. Standard

thermostats simply turn on and off the burner.

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 tempera-

ture. For standard models (T), the control knob

can be set to any heating level between 1 and 5.

All plaques will turn off and on. For infrastat

models (ITA), the control knob can be set at

the 1, 2, 3 or 4 locked positions for the desired

comfort level. The number of plaques selected

will turn off and on.
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.
