This is a flue from a 150000 BTU boiler.
Improperly terminated, no cover. Any other comments would be appreciated.
Thanks

too close to window

That was my initial thought. But if what my HVAC tech provided me with is correct, then that is not the case. (See attached).

This is what I go by for my area, yours may be different.

Stupid not to go to the roof.
Are they pretending it is a cat 4?
The vertical run needs to be 125% longer than the lateral.
Is it?

That was for direct vent but this is not direct vent as far as I know.
Have more direct vent code here however…

2006 International Residential Code for One and Two Family Dwellings

Some oil fired boilers have a power vent

At a 150000 BTU’s I would not care what **Code **says. My recommendation is to run it up to the roof PERIOD or at least pass the neutral pressure plane of the Home.
Many investigations I have done revealed fumes going back into the home and there was no violation of minimum code.
