INSTRUCTION FOR WIRING A POWERMAX INDUCED DRAFT
ASSEMBLY TO A POOL HEATER WITH IID IGNITION.
WARNING
Make sure all power is off before wiring the heater. The Power vent assembly only operates on a 120 VAC.
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.
1. Route the PowerMax wiring through a corner opening into the lower compartment area.
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).
4. The green wire that comes from the relay connect to the same place ignition module is grounded in the
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.
7. Connect the branch circuit’s safety ground wire (green) to the heater ground lug.
(Refer to Figure 4.)
CAUTION
The heater must be electrically grounded and bonded in accordance with the local codes or, in absence of
local codes, with the latest national codes ANSI/NFPA No. 70.
