Mounting Bracket

Select the location for fan mounting which minimizes noise

generated by fan operation，and allows sufficient access for

installation and maintenance. Secure the mounting bracket

to the support beam with screws.

Connect the ductwork. Use duct tape to secure all of

the ductwork connections so that they are air tight. A backdraft

damper installed at the outlet is highly recommended to prevent

cold air from entering the dwelling.
