    more wrong with this

    They cannot discharge the exhaust into a well like that. It will recirculate exhaust gases into the intake, which is probably why they flipped the ell even if they didn't have the grate covered with leaves. They should snorkel the exhaust up and out of that well pmi. That's a rain catcher as is. The acidic condensate will eat up that grate in short order as well as the galvanized steel well.

    Not to mention it has to be 12" above snow line. And ss mesh.and what is this pp pipe with elbow in the rear. Is this condensate discharge? They cannot discharge to outside. They will get an ice plug. Condensate must discharge into sewer system after neutralization.

    Any possibility that there is exhaust regurgitation back into the intake with that Concentric? At least they painted it to be color coded with the rest of the house.

    I had a whole tribe of similar photos in the camera that someone needed more than I. One was of a exhaust vent that was installed legally, a barely legal distance from a LPG regulator, that landscapers raised the grade by putting PT 2"X12" timbers 6" from the foundation along the whole side making the exhaust vent and the regulator vent below grade in a confined space. It was like that when I got there. All signed, sealed and delivered by the AHJ's.

    Where I used to work, they'd bust chops and deny a final inspection signoff if the shade of white paint was wrong. But something like that would be ignored by the ignorant.

    Critter Entrance:

    You don't understand. That's the critter door. So the critters have entrance to the warm inside. Those critters have a right too. Haven't you ever experienced the excitement of pulling down a piece of insulation and mouse poo rains down into your hair and down the back of your neck?

    If you haven't, you must not have pulled down any insulation in a cellar with critter entrances. Something to look forward to. .
