Flue reducer

[philoÂÂ]

I need to replace the flange for my furnace flue.

The old oil furnace had a 6" flue and my replacement gas furnace has a

4" flue.

The reducing flange at the chimney is rusted out and when I went to Home Depot all they had were adapters for 3" exhaust pipes.

This should be a common item but I don't seem to be able to find a replacement.

I suppose I could just make one myself I have quite a bit of heavy duty sheet metal.

Try a stove shop or real hardware store. Home Depot has 250,000 items, but not what you need.

Kind of what I thought.

Thanks

I bet I end up making my own though.

Plumbing/heating supply would have it. Plumbers put in WH all the time and have to work with vent pipes and such, plus they usually sell boilers, etc too.

I found a nice plate that's about 3/8" thick and all I have to do is cut a hole in it with a 4" hole saw. The piece that rusted through was almost paper thin yet it laster over 20 years. The piece I intend to put in should last 100 years.

We anticipate your update in 100 years, via Google Groups.

LOL

actually I went back to Home Depot for some other parts and looking in the "duct" isle again and found some 4" flanges. Since they are so thin I bought two and doubled them up. So, they may only be good for 40 years.
