NOTICE: The fan and electrical connections must be accessible for servicing per local code requirements.

NOTE: If the fan housing is installed in a 2 x 4 wall, the front of the housing will protrude approximately 1/4 in. (6mm) from the finished wall. See Figure 11.5 on page 61.

8.Attach enough 6 in. (152mm) B-Vent as required for your installation to the fan housing. A maximum of (4) 90° elbows is recommended. Securely twist lock the B-Vent to the Adapter.

Also screw the B-Vent to the outlet box on the fan housing. See Figure 11.6 on page 61. Support duct at intervals of no greater than 4 ft (1 m) as required by local code.
