Hello all,
I inspected a house that has an exterior utility room with a furnace and water heater in it. The exhaust flue goes up and is attached to the deck, which is obviously very easy for anyone to grab. It is B vent, however, any ideas how to write this up? The town, passed them, which I found amazing especially with all the vegetation around the flue as well.
Thanks for the advice.

Sorry didn’t realize they would show up side ways.
My biggest concern would be the height of the termination and if it is properly supported all the way up. I can’t quite tell in your pics the height, but I wouldn’t want it discharging to close to the deck where people will be sitting. How high is the discharge above the deck?

The B-vent’s exterior surface is designed to not exceed 90°F No hazard here. Common bathing water temperature is 100°

Its higher than the deck, but the support ends at the deck surface
So, 8-10 feet or so unsupported? Did it feel secure?
Type B gas vent as requiring 1" clearance to combustibles.
Need more visual information. Poor image orientation and images.

Just STOP it. (You know what I mean)!

I would just identify flue material. Not an issue

This might be helpful when posting your photos on here. Try using the “upload button” vs a copy and paste. This will allow us to see the original image in most cases.
This image is interesting. There is a lot going on here that likely needs a deep dive. It appears the exhaust is for the boiler.
That looks to be a Navien tankless. You may be able to find their installation manual here:
I am not sure about the boiler.
Here are a few inspection points for both (many can add more I am sure)
- The boiler appears to be sitting on top of a gas line.
- Were there sediment traps?
- Proper TPRV or PRV discharge?
- Make-up or combustible air supply?
- Thermal expansion devices?

Well, thank you for that!

My apologies for any confusion…
That was for Robert, not you.
He needs to learn to curtail his insulting tone on this MB.
His life revolves around bashing Pres. Trump, and stalking me around the forums and attacking when he gets the chance.
Total disgrace to all Canadians, (with only one or two exceptions)!
Please reload the Mechanicals closet pic using Brians suggestion.
I’d love to get a better, zoomed in look into that closet.
Thanks.
Mariann,
The flue exhaust installation could have been done better probably but it’s one of those situations where it’s technically not a defect bc the B vent has clearance. Maybe mention keeping the vegetation cut back away from it.
Brian is pointing out some issues inside that utility closet that are pretty important. It also looks like the Navien isn’t hooked up correctly for it’s required maintenance flushing (appears to not have the flush connectors the plumbers use for this). You could probably spend an hour inside that closet finding issues. The flex gas line under the boiler is very concerning because it appears to be stretched and stressed at the manifold connection. But the point is there are much more concerning things in there than the exhaust.
And try to ignore the petty infighting of the children here.
We need to stop making stuff up and trying to apply a requirement that does not apply to the situation.
A deck is not a roof. Concerning the roof requirements, it’s not that the roof will catch fire because it is too close, it is because of the effect it has on the flue drafting properly…
Also, a chimney and an appliance flue are not the same thing, should you ask.
So, trees will not affect drafting?
