Typical 3-Zone Gas Fired System

CHECKING THE SYSTEM

Turn on the electricity. If gas fired, be sure pilot is lit. Then check each zone separately as follows:

1.Turn thermostat to highest setting. Damper vane for that zone will open and furnace burner will come on as auxiliary circuit is made on damper motor.

2.Turn thermostat to lowest setting. Damper vane for that zone will close and furnace burner will shut off as auxiliary circuit is broken on damper motor.
