TOPIC: B vent

Here is a good link Mike.

It explains various ways of venting fireplaces.

I saw that one.  I guess I didn't go down far enough.  What I was looking for was something that stated the different grades of vent pipes and their uses.

Perhaps this is better as it has a calculator.

Thanks for all the help you guys. Here is another link that I believe answers the question. www.inspect-ny.com/chimneys/B-Vent_Chimneys.htm . it states that "B-Vents are not for use with fireplaces, woodstoves, or oil-fired equipment."

Yeah that works, but what is the correct pipe to use?  The only thing I can find is that its designed for all fuels.  I was trying to find out what its called though.  You have the single wall, then the B-vents, then the all fuel.  I think all three should have a letter designation like the "B-vent" does.  Your question just got me curious!  lol

Here are a few illustrations for you.

Yeah there ya go.  That's the stuff I was trying to find.  I better save that stuff for later!!!
