I don't think that's a short radius ell, I think it's a no radius ell.
Probably not idea, but long as it's not a long run it'll likely never know the differance.
Vents only go 30', chart says 2" good up to 100'. Each run has only 3 90's per so not a problem, even being short radius ells.
we had a similar discussion in the shop last week, the inspector will let flex count as a drip leg here, too. Apparently the ribs are supposed to catch any oil etc. I don't care for it and i'll stick with the drip leg myself. good looking job!
If the furnace was placed under the ductwork, looks like at least two fittings could have been eliminated- the ell above the transition and the goldberg.
Those two fittings are worth around 170 feet of duct, certainly worth the little bit of space gained by cramming the unit against the wall.
I wouldn't be surprised if the unit shut off on limit, and a future coil would probably freeze.
The throat radius is what matters, not the heel. The "all radius fittings for me" is a bit misplaced.
Why not mount the filter horizontally?
It looks good, though.
I like the owners manual holder. Nice touch.
Proper Prior Planning Prevents Piss Poor Performance
"There is hardly anything in the world that some man cannot make a little worse and sell a little cheaper, and the people who consider price only are this man's lawful prey. It's unwise to pay too little.
When you pay too much, you lose a little money -- that is all. When you pay too little, you may lose everything, because the thing you bought was incapable of doing the thing it was bought to do.
The common law of business balance prohibits paying a little and getting a lot -- it can't be done. If you deal with the lowest bidder, it is well to add something for the risk you run. And if you do that, you will have enough to pay for something better."
