The following instructions configure the power vent assembly to operate with the PowerMax on a single 120
VAC circuit. Take care as wiring errors may burn-out the transformer and blower motor.
If the Field installation is supported and the installed heater operates from 230 VAC, there must be a
separate 120 VAC service ran for the Power vent assembly.

2. Disconnect the orange wire from the ignition module pin 6 (24V) and connect it to the orange wire from
the air pressure switch.
3. Connect the blue wire from the air pressure switch to the ignition module pin 6 (24V).

main control box.
5. Twist the red and white/red tracer wires from the transformer with the white wire from the fan motor.
Using a wire nut, connect the common wire from the 120 VAC line circuit with these wires.
6. Twist the black and white/black tracer wires from the transformer with the black wire from the fan motor.
Using a wire nut, connect the hot wire from the 120 VAC line circuit with these wires.
