Proceed to STEP 4.

STEP 4 - Now carefully cut hole in ceiling flush with inside of frame.

STEP 5 - Attach gasket to bottom of fan frame. Be sure gasket seals opening on all sides. Set fan over opening. It is not necessary to anchor fan as its weight keeps it in place. Nailing fan in place is not recommended because this tends to transmit any vibration to the framework of your house. (See Fig. 13.)
