Hmmm have a vague recollection of that thread.
What was subject area ?
Nor will I, unless they call it a “main sub panel” or something stupid like that 
What if it IS the main one 
That would be the primary remote distribution panel ,Juan.
Lol. I was kidding
I am really starting to wonder about you J.
Why? It seemed to me that the area causing some confusion in this thread was the difference between a chimney and a vent. I posted a link to an article that discussed the importance of using proper terminology and it used chimneys and vents as an example.
I thought it was a valid link.
Juan, maybe you could offer Kevin some personal instruction. Let him choose the course. :mrgreen:
I honestly don’t understand the joke
Kevin has stated numerous times he was/is an educator, in the home inspection field. Also claims to have over 9000 hours of schooling.
I think he may have missed a class or two and you could help him out.
Maybe. He can trade me a course in IAQ
Sorry Juan I was talking about the other J. Just don’t care to put anymore than this.
CSA 8.14.2 Except for special venting with positive vent pressure, a vent shall extend not less than 2 ft (600mm) above the highest point where it passes through a flat roof of a building and not less than 2 ft higher than any portion of the building within a horizontal distance of **10 ft **(3 m).
2/2/10 rule
8.14.4
A **chimney **however must be at least 3 feet high even if it is gas and must follow the same rule of 2 feet higher than any portion of the building within 10 ft.
3/2/10 rule
So Jeffrey you said 8 ft away from a wall but here in good old Canada it is 10 feet.
Thus my comment " Not in my neck of the woods."
Some manufacturers do allow closer but that is not what is at issue with the OP
Under 8.14.3 of special positive pressure venting it can be as low as 18 inches and only 18 inches away from any object.
So HI’s do need to understand the difference.
I don’t know about Canada, but this does not apply to the US for B-Type vents.
B Vents, as I said in my initial post, must be extended above the next roof line if within 8 feet of a vertical wall.
So even the IRC does not apply either as it also has the 2/2/10 rule. Why has there been an exception is the manufacturer allows it to be 8 feet in the US not that this is accepted practice and so therefore not recognized in the guidelines here in Ontario or in the InterNachi guidelines.
Question is would 8 feet rather than 10 feet make a difference? I don’t think so.
[FONT=Helvetica][size=1]Wrong again.
What I show below is listed in G2427.6.3 of the IRC and also required be the Manufacturer here.

The vent must extend
through a flashing, and should terminate with the lowest discharge
opening no closer to the roof than the minimum height shown in the
table below. These minimum heights may be used provided the
vent is not less than 8’ from any vertical wall:
[/size][/FONT]**[FONT=Helvetica-Bold][size=1]TABLE 1
**[/size][/FONT][FONT=Helvetica][size=1]Roof Pitch Minimum Height
Flat to 7/12 (305 mm) 1.0 feet
Over 7/12 to 8/12 (451 mm) 1.5 feet
Over 8/12 to 9/12 (610 mm) 2.0 feet
Over 9/12 to 10/12 (762 mm) 2.5 feet
Over 10/12 to 11/12 (991 mm) 3.25 feet
Over 11/12 to 12/12 (1218 mm) 4.0 feet
Over 12/12 to 14/12 (1524 mm) 5.0 feet
Over 14/12 to 16/12 (1829 mm) 6.0 feet
Over 16/12 to 18/12 (2134 mm) 7.0 feet

Over 20/12 to 21/12 (2438 mm) 8.0 feet

We are not even talking about a pitch! I wish not to play games Marcel. That table does not apply even close to the PO question.
It could say 4- 6 feet away and it would not matter as it must meet the 2/2/10 rule unless it is a pressurized vent or chimney.
As for the pitch that is an exception because a chimney would need to be too long to follow the 2/2/10 rule under all circumstances, however I have seen some pretty long chimneys needed for wood and oil.LOL
So in question is if it is 8 feet away or close you don’t tell them to raise it above the vertical wall and here in Canada we follow the more stringent of 10 feet from the vertical wall according to the CSA Codes and IRC graphic on page 398.
They may have changed this but I doubt it unless they are walking backwards in safety.
Correct. If >8 feet, it does not need to be raised.
Okay then…if the vent is >8’ away from a vertical wall and the proper height above the pitch of the roof, you are good to go.
