New Oil Boiler Installation- Guidance on Exhaust Ducting

Andrew518 Member Posts: 2
Hi- I just had a new oil boiler installed by a reputable local company in the Upstate NY area. In taking a closer look at the installation, the exhaust piping/ducting seems to be poorly done, as there are significant gaps (see pictures). I posted on facebook and got some guidance but I am hoping for more expertise on this site so I can follow-up with my installer. I am not running the boiler in the interim.

    The draft regulator should be on the horizontal pipe, so the existing Tee should be an elbow. 
    And a squat reducer into the 8" might seat better. 
    Overall the joints need to be tighter. 

    And it's 2023. Circulators on the return?

    Is that a check valve on the oil line? Get rid of it.

    No Firomatic valve at the burner?

    It's wrong and not to code. Was a permit pulled?

    There was an error rendering this rich post.

    No permit that I'm aware of- I was under the impression the contractor would pull that if required

    I am in MA. but upstate NY anything goes. I have worked up there a few times and the workmanship is awful. It's like the wild wild west.

    Have them come back and install the draft regulator in accordance with the MFG instructions. Every joint in the smoke pipe needs at least 3 screws (that is code) and get the smoke pipe to seal in the fitting about 1 1/2 inches by crimping it with hand crimpers if need be. The oil line needs some type of protection. It should be sleeved in metal pipe or conduit, and you need a firomatic valve at the tank and at the burner.
