with the provided screws and a bead of silicone sealant. Then secure the trim plate to the outside wall
with silicone sealant and the appropriate fasteners. Install the 4” PVC Tee as shown in Fig. 2 using
silicone sealant and a sheet metal screw to secure.

pressure switches. The molex connection plugs in to the ventor assembly connection, (See Fig. 2).
The other end is connected to the furnace plug. The cable should be securely supported.
12. If local codes require that the cable be run through a conduit, remove the molex end with a molex pin
removal tool or equivalent. Care should be taken to not damage the pins. Run the cable through the
conduit and then replace the molex plug.
