Installation Instructions

THERMOSTATIC CONTROL OPERATION (SELECT MODELS)

The control knob can be set to any comfort level between

"HIGH" (5) and "LOW"(1) (See Fig. 25).The thermostat used on

this heater senses the room temperature. At times the room may

exceed the set temperature. When this begins to happen, the

burner will begin to modulate the BtuH down until the unit meets

the desired heat setting and shuts off. When the room

temperature drops below the desired heat setting, the burner will

cycle back on. The unit may start at a lower BtuH rate if the room

is still warm.

MANUAL CONTROL OPERATION

Manual valves remain burning at the desired setting until

manually turned to OFF " "(See Fig. 25).

OPERATION

INSPECTING BURNERS

Check pilot ame pattern daily when in use and at least yearly by a qualied service agency.

PILOT FLAME PATTERN

Fig. 26 shows a correct pilot ame pattern. Fig. 27 shows an incorrect pilot ame pattern. The

incorrect pilot ame is not touching the thermocouple. This will cause the thermocouple to cool,

which shuts the heater off. If pilot ame pattern is incorrect:

• turn heater off (see “To Turn Off Gas to Appliance” on page 19)

• see Troubleshooting pages 23 through 26.
