The chimney in the picture doesnt follow the 3,2 10 rule. It appears to be about as high as the ridge.
In the picture it is hard to tell.
In the archives I submitted a post pertaining to chimney height.
J. Pope replied that being a gas appliance it follows a 8 ft. rule and needs to extend 1 ft. to 8 ft. vertical. If the roof slope is < 6/12 than 1 ft. is acceptable.
So according to that statement the chimney height is OK.
Therfore I dont need to call it out as being to low.
Dave, this is a vent rather than a chimney and therefore falls under a different code, Jeffs advice is sound, but to expand on it a bit here it the abridged table from IRC 2426.6.5 and UMC T8-1
6:12 pitch = 12 inches
6;12 to 7:12 = 15 inches
7:12 to 8:12 = 18 inches
8:12 to 9:12 = 24 inches
9:12 to 10:12 = 30 inches
10:12 to 11:12 = 39 inches
11:12 to 12:12 = 48 inches
The “chimney” is realy a decorative feature and from a code perspective not part of the vent requirements.
In my report would you still note this as a chimney for location & type?
Example
Location…East slope…Chase…Framed…Flue…Metal
I need to look closer at the chimney to see if it is missing a cap like Tyrone metioned.
I was there yesterday setting up the radon monitor at a vacant home and did most of the inspection. The roof was snow covered and I didnt inspect it yet.
i’m assuming that the post is for the “chimney” on the left and up hill and not the “vent” of P.V.C to the right, right? or left, or correct…great now my brain hurts.
