Anyone can see it's too close to the turbine vent.
I don't do code.
It's crooked and rusty.

This is like a joke question..?

[Ted Allen]

Hmmm, actually if that is a roof vent.............. going out.......... Then it may very well be OK..

[Ted Allen]

I say it is OK, but the gas vent should be taller.

[relliott]

Tallen ,you are correct, as it needs to be 24 inches higher than anything within 10 feet if it is B vent.

The wind turbulator appears to be recent install.
The "B" vent stack is too close to it.
Bad combination in any case.
Call it out as further assessment required.
Let the trades people figure it out.
I do NOT do code (reference), just common sense.

The top of the chimney must be 2' higher than anything within 10' of it.


Potential back draft problem.

So far there are 3 votes that this is ok, yet not one explanation for why.
Lets hear it.

Hint:

The turbine is not combustible.

The turbine discharges air from the attic space.

The unavailable furnace mfgs. installation instructions rule.


Now let's hear why most think it is an improper install.

Gave it to you already and the 24 inch rule applies, with minor modifaction for roof slope.

Show us Manufacturer that says I am wrong Mike.

I try to approach these unusual situations from logic.

What is the potential hazard?

It may well be wrong but without a known hazard and lacking the installation docs, why?

NO NO Mike
You are answering a question with a question.

Your installation guides are all over the internet.
Argue with, them.

Find one that is different from what I referenced.

Why does a brick veneer wall need a one inch space rather than a 3/4 inch space? I do not know that either.

Ever hear of the 3-2-10 rule.? Me too, but I just write it up.

Gee ,am I being hard on this.

Seriously I would imagine there is something called back drafting , which may come into play.
