Rubber flashing on B-vent

[mridgeelk]

I don't believe that this roof jack flashing installed on the B-vent is correct. Is it correct and and if it isn't where is the regulation stating so? Thanks, Ed

Hi,

Go here and look at item #2

http://www.plumbingsupply.com/roofflashings.html

I didn't know the answer - I found this in 20 seconds by googling "plumbing flashings".

The big pipe is the B vent? Are you asking about clearance to combustibles or are you asking about crappy fit on the plumbing vent?

Thanks for the tip, Mike. I did note the prolapsed flashing on the plumbing. Ed

Personally, I wouldn't be concerned with temps at the roof with that flashing. That stuff is rated for over 250°F and I don't think I've ever had a B vent anywhere near that hot at a roofline.

In my areas the one I have seen for B vent is a red looking one. I do not remember who makes it.

This link will take you to more flashing. http://pipebootexpress.com/?gclid=CKfYu ... FQodkVt8_A

If you will look in the roof forum you will find where I posted a photo and we talked about flashing.

Thanks for all the info, I had not seen the previous discussion. About a month ago I found a similar installation only this was on triple wall pipe from a wood stove. I wrote this as incorrect.
