This is a new Goodman high efficiency unit. Normally it would be 12 inches above the eaves, 2 feet from anything within 8 feet, I know, but since it is HE it only needs to be at least 1 foot above grade, Because the vent is right on the front porch entry to the house, would you recommend a change in the termination? I did for safety, not manuf. reqs., but thought I would ask the learned here.
It comes out of the little house next to the front window.
It should look like the photo I posted and pointing away they are going to have condensation freeze problems on the siding. I don’t understand why they would have switched to a b-vent from PVC, that makes no sense. Did they run fresh air in PVC and where is the pipe for that?
Because you generally see the intake and exhaust together, does not mean they have to be together. The intake is set up in another area (although there is not enough combustion air, as I will note in the report) and is fine. My question is not why they did it that way, my question is do you see a problem?
They do need to terminate together. They need to be in the same pressure zone. For example they need to be on the same side of a roof, or the same side of a house. It needs to be plastic all the way. You’ve described two concerns as far as I can tell.
I would recommend checking with the local AHJ concerning combustion air intake it is allowed by Okla AHJ to be taken within the area of the furnace many times no pipe is connected to the furnace at all.
Charley - just did a permit search and the AHJ has nothing to do with it since there was no permit pulled on the furnace. Last permit was in 2011 and the furnace has a manuf. date of 2014 (Jan). Probably just an oversight… I am sure.
