THERMOSTAT CONTROL OPERATION

(Thermostat Models Only)

The thermostatic control used on these models differs from standard thermo-

stats. Standard thermostats 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 HI and LO.

Note:

The thermostat sensing bulb measures the temperature of air near the

heater cabinet. This may not always agree with room temperature (depending

on housing construction, installation location, room size, open air tempera-

tures, etc.). Frequent use of your heater will let you determine your own

comfort levels.

2. Follow steps 1 through 5 under Lighting Instructions, pages 17 and 18.

3. With control knob pressed in, strike match. Hold match to pilot until pilot

lights.

4. Keep control knob pressed in for 30 seconds after lighting pilot. After 30

seconds, release control knob.

5. Replace front panel.
