Typical Multi-Zone Gas or Oil 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.
