5.5" diameter chimney liner

[esh21167]

I was checking out my chimney before ordering a liner and I don't think I'll be able to get a 6" diameter liner down it. It's an exterior masonry chimney almost 30 feet from hearth to top. I'm installing a Napoleon 1401 insert and wondered if a 5.5" diameter liner would provide enough draft. Thanks.

Yep, mine is only 22ft and a 5inch liner. lots of draft. actually more draft than with a larger dia. liner. only thing is , burn hot and clean, cause only a little amount of creosote can effect the draft. simply because the diameter is so much smaller. on the other hand that smaller dia. will give you greater draft.

Dry nicely seasoned wood is the KEY here. ;-)

With a 30' stack on the Napoleon, too much draft may be a more real problem. The 5.5 pipe may actually help.

I also have a 5.5inch liner in an exterior chimney with no issues.

Also, are there 5.5 to 6" adapters for connection to the insert?

When you order the liner kit specify a 5.5 to 6 inch insert adapter.

Yes, but they are hard to find since most stoves in the U.S use a 6" flue ID.
Your local hardware/hearth store should be able to custom order one for you.
