Panasonic FV08VQ5 or FV11VQ5 Bath Fan Installation

Identical fan body hardware is used in Panasonic FV08VQ5 and Panasonic FV11VQ5 fans.

A story is told in Google Photos albums: 

This installation involves separation of the fan/ motor assembly, and fan body for easier handling. It is possible to install without such separation.  

In this installation, further steps effect novel ducting of the fan through the roof:

Please pick document posted 4/9/2011, Replace Bath Fan.

The novelty in ducting includes roof sheathing reinforcement that would be mandatory in many installations as with the common sheathing plywood over skip sheathing, where skip sheathing may be so weakened as to not tolerate weight of a worker on the roof. A further novelty is an invented three-piece penetration, the 4" solid steel duct, a collar assembly for water-tight integration with composition shingles, and the roof cap seated only under top-course shingles.

Panasonic FV08 VQ3 Bath Fan
