2. Lift the control panel up so the control panel is free of its
hinges. Orient the control panel so there is easy access for
mounting components to the control panel (Figure 14).

3. Using the two #8 screws that are provided, screw the
transformer to the control panel in the transformer mounting
holes provided in the panel.
4. Mount the relay in one of the three relay mounting holes in
the control panel making sure that the threaded stud is in the
smaller hole and the metal tab is in the adjacent hole. Screw
the provided nut onto the threaded stud from the opposite
side of the control panel.
5. Remove the knockout for the vent switch (Figure 15) located
in the control panel and snap the vent switch in the knockout
hole with the terminals inside the control panel compartment.
The numbers on the switch should be facing toward the
control board. Place the supplied label just above the
switch.

7. Once the wires are routed into the control panel compart-
ment, attach the door motor and vent fan (for PVK kits)
terminals to the 24 volt side of the transformer (see Wiring
diagrams).
8. Take BK 16 and RD17 fan motor wires from the control
board and place on the terminal strip (Figure 16).
9. Take BU10 wire from the #3 terminal of the relay and place
on the control board FAN LOW terminal. Take the BU15 wire
from the #8 terminal of the relay and place on the piggyback
terminal of BU10.
10. Take the BU4 wire from the #4 terminal of the relay and
place on the control board FAN HIGH terminal.
11. Please refer to the following schematics for proper electrical
wiring if the chassis has any of the following kits previously
installed:
Power Vent Kit
Power Door Kit
Hydronic Heat Kit
Hydronic Valves
