What exactly is the verbage and why did the inspector say it's important? I really can't fathom how this is any worse than going through the stud wall.



Suppose a foundation comes up extra high, like bottom of the windows? Is it foundation if it's concrete? What about a stone foundation that goes to brick? Why would the brick be any better than going through the stone or concrete?


When going through concrete below grade we use link seals, above grade black iron would have some foam insulation for a sleeve and be caulked outside. We almost never bury black iron though so below grade it's really just water and sewer lines. We try to keep anything that isn't yellow PE gas pipe above grade.

I cant think of an logical reason why venting cant go through foundation wall.
Whats the difference if it goes through brick ?

All its going to do is create less options for the owner.
Guess your getting an electric tankless.

It can here our code allows it as long as it terminates 1 ft .3 mt above grade. Some jurisdictions require additional height for average snow depth.

Maybe you should check the definition of a foundation wall in your Building Code. I don't remember anything about foundation walls in the code here, A wall is a wall.

Here in B.C. I've never entered below grade as it's not permissible unless it's approved by "The Authority of Jurisdiction". If I did have approval yea I would use a link seal as well.

The Section you reference is from the IPC.

Here's what the UPC has to say.
1210.1.5 Piping Through Foundation Wall
Underground piping, where installed through the outer foundation or basement wall of a building shall be encased in a protective sleeve or protected by an approved device or method. The space between the gas piping and the sleeve and between the sleeve and the wall shall be sealed to prevent entry of gas and water. [NFPA 54:7.1.5]
