BW for water heater

[Marc M]

I thought BW was never to be used for anything other than a wall furnace. Actually, the label said this was a "B" vent not BW.:confused:

looks like ductwork modified along with single wall vent pipe that is not seated togeather properly, is not hung properly, and not allowed in that location.

This subject was covered in great depth at a posting in 2006 - go to
Type BW Vent - Home Inspection & Home Inspector Services For Inspections and Inspectors (http://www.inspectionnews.com/ubb/Forum7/HTML/000292.html)

I can't imagine it has changed any since then.
