Chimney Pipe???

[WidowMaker]

New guy here, been lurking for awhile. Now have a question..I posted this on the Arborstist board but haven't gotten any responses as of yet...



I came across this while searching for an on-line source for double and triple wall pipe...

" When we purchased our stove this year, I asked about triple wall stove pipe, and was told that it is not allowed in code any more...(I guess code is now double wall insulated stove pipe)"


Can anybody provide any "code knowledge" input on this subject. A link to appropriate code source would be appreciated...TIA

I believe triple wall is tested to UL 103 whereas double wall insulated is tested to UL 103HT (which triple wall cannot pass due to the higher temperature test). Triple wall can still be used, but not for all situations.

The simpson duravent triple wall pipe is just like the double wall except it has an extra air insulation chamber which is supposed to keep the flue warmer and give better draft. According to their brochure both are fine to use for solid fuel. We only use the double wall because it doesn't make sense to pay extra for the other stuff when the double wall works just fine.

The person that said triple wall was not allowed was probably thinking of the old air cooled systems many prefab ZC wood boxes used. Its not against code to use it that I know of, but no one uses it anymore. Most have switched to a double wall system now which uses the same air cooling system. Neither of these air cooled pipe are safe or allowed to be used for a EPA wood stove.
