1. Slide the outlet of the Power Venter over the inlet of the Vent Hood and connect them together using the provided screws, (See
Diagram C). If you are unable to make a direct connection to the Vent Hood, vent pipe may be installed between the Power Venter
and Vent Hood. However, all vent pipe connections after the Power Venter must be sealed with high temperature silicone caulk or
aluminum vent pipe tape to prevent flue gas leakage, (See Diagram D).
2. Temporarily support the Power Venter using wire or a ladder and assemble the mounting brackets, (See Diagram E).
3. Install plumbers strap from the Power Venter to the floor joist, (See Diagram E).
4. Install 4 inch vent pipe from the Power Venter inlet to the appliance flue outlet avoiding elbows
