The logic is exquisite.
I disagree with the assumptions.

i cam here to ask the same thing. is it like an old lowboy where where the vent ran out the back above the blower.JUGHNE said:The few (lowboy) oil furnaces I have worked on would have the first 3-4' of exhaust in the RA plenum just above the blower.
Perhaps this 6" goes thru the SA plenum and exits the other side.....might explain the condensation leaking out of the lower fittings.
also, the combustion efficiency isn't 100% so it isn't 100% efficient even if it vents in to the supply plenum.0 -
This looks to be a plain jane 80% furnace, blower on the bottom, AC coil above burner.
They may have thought by putting the exhaust pipe in the air stream they could milk more heat out of the furnace.0 -
Or decided to go through instead of around. The proximity of the vent and the filter in those lowboys seemed to be an issue.0

It's an optical illusion. I don't see a clinch collar. I don't see any flange or masking or retort cement where they (supposedly) meet. I'm sure if the angle was 90° from what we're looking at, we'd see there's no penetration.
Unfortunately we can't see where the water heater flue is going.
Anyway, I call BS.1
