question on VF3000 flue size

PostBy: Motorbike On: Fri Sep 19, 2008 8:40 pm

I need to get some flue pipe for my boiler. The manual says to install a 6" flue pipe from stove to chimney with a baro damper.
The actual flue connection on the boiler is 6" pipe (6-5/8" o.d.).

I was told by the plumber that is helping me install the boiler to buy 7" flue pipe. The 7" flue pipe is 7" o.d. this leaves a 3/16" gap all the way around the flue pipe connection.
I read in another thread that the flue should fit tight over the connection on the boiler, so should I go with 6" flue pipe?

Also, do I need to get the black stove pipe or will the galvanized stuff work too? The plumber that is helping me told me to buy the galvanized stuff.

Thanks for the help.
It has been a stressful time the past few weeks. My boiler came in, i finally got it in my basement and have been working on the plumbing. Coal was delivered today, and I was up late last night tightening up my coal bin.
I'm a coal newbie and can't wait to get this boiler running.

Buy 6" black 22ga flue pipe. Install it into the inside of the 6" connection at the boiler.. Use black heavy guage pipe, Galvanized gives off poisonous fumes when heated hot enough.

The manual references 6" I believe, however the crayon it was written in might have rubbed off :lol:

Use a 6" starter fitting that has the ridge in the middle. It will fit snugly into the vent pipe of the VF3K.I'll post a picture of one when I get back from vacation.
