HVAC dudes

[Bain]

There have been some recent threads about sizing furnaces and ductwork, and other installation nuances. I was reminded of those threads when I saw the draft hood in this photo.

There's one way to do it correctly, and one way to do it wrong and, almost predictably, the schmuck got it wrong.

Do I want THIS installer telling me how large my furnace should be, and how the ductwork should be configured? hahahahahahahaha . . . . . .

Oops

[Jim Katen]

That's a remarkably common defect. I'm wondering if there aren't people out there who think it's the right way to connect those things.

"...I saw the draft hood in this photo."

Horizontal vent termination. A draft hood is something completely different.

[John Dirks Jr]

I never thought to check for the reversed connection there.

John, was it just luck that the thing was running and spreading the condensate on the wall at the time you were on the exterior? I might make it a new practice to ramp up the furnace and check the termination on the exterior.

A very good way to eat away that brick

Bill: Roger that.

John: Like Jim said, it's fairly common. You can typically eyeball the intake- and flue-pipes and know whether they're correct. If a finished basement is involved, you can put a hand on the draft hood horizontal-vent-termination ports when the furnace is fired to see what's up.

I never have liked the looks of those things,the fact that most of the ones Ive seen lean to one side or the other doesnt help any! [:-censore
