Wired and AC line near Exhaust

[chall20 (Chris Hall)]

NM wires and AC lines right next to flue. No visible signs of damage but I figured this would be energy inefficient and possibly damage the wire insulation. Whats the necessary clearance? 1 inch or 2?

IMO… 6 inches to the vinyl sheathed conductors.
What do you mean by “AC line”? I don’t see a ‘line-set’ in the photo.
Ducting is a non-issue.

I’m sorry the second photo didn’t upload

I’ve never seen a line-set that color. Is that insulation or rubber or ??
Assuming it’s non-metallic… 6 inches.

Copper. Maybe the discoloration was heat related?

I’m going to say 1” clearance from all combustible’s. This is the minimum standard.

He’s NOT showing B-vent in his photo’s, but you are. NOT the same thing!!

[chall20 (Chris Hall)]

There was no listed labeling on this vent to suggest b vent

[mwilles (Martin Willes, CMI)]

You’re right it’s single wall

Don’t need a label. Just look at it!

[chall20 (Chris Hall)]

lol yes I thought it was single. Don’t know why I asked 1 or 2

Double vs. single wall, different.

[mwilles (Martin Willes, CMI)]

That has already been addressed.
