Chimney/stove pipe height?

[Beagleman]

How tall does your chimney/stove pipe need to be?

This would really depend on the stove that is being used. Typically its 12' or more. The chimney needs to extend above the roof at least 3 feet. It must be 2 feet higher than anything within 10 feet, measured horizontally.

Most modern EPA stoves require 15' flues. This is what they are EPA tested with. Some catalytic and older stoves can get away with less. We get a lot of folks here with too short chimneys and poorly performing secondary tube stoves. They add 3-4 ft of chimney and suddenly it's like they got a new stove. If there are elbows or tees on the flue system they will slow down the flue gases. Deduct about 3' height for each 90 deg. turn in the pipe. Also, chimney height depends on the installation altitude. A modern stove installed at 5000ft is probably going to require an additional 5 ft of flue to perform well.

Here is an example stove's (Lopi Endeavor) chimney requirements:

Thank you for your help. It's a englander 30.

The ideal flue for the 30NC will be 6", straight up 15-25 ft. That is not saying it won't work with a 14' flue. Sometimes it depends on the location of the chimney relative to the house roof and terrain. Is this a new chimney installation or will it be tying into an existing chimney.

Its a new chimney Install.

Sounds good. Congratulations on getting a good deal on the stove.

On my 30, I have 4 foot inside to a 90 degree bend, then 4 more foot to a cleanout, then a whole bunch of chimney outside.
