INSTALLATION INSTRUCTIONS
DAMPER MOTOR(S) CONNECTION
The damper motor opens and closes the flap which controls the combustion air. Both primary air (front
of unit) and secondary air (back of unit) are controlled by a damper motor. There is a central connection
for the damper motors in the junction box on the side of the furnace. This connection is in later diagrams
referred to as “damper motor”. It controls both damper motors and involves a bypass switch, which
prevents the primary air damper motor from opening when the bypass is open.
NEVER CONNNECT DAMPER MOTORS TO 120V. CONNECT ONLY TO 24V
