Does the exhaust and combustion air really need to be separated? Just trying to think about how this could be a problem in a closed 90% furnace. Smaller ones are from the furnace larger one is power vent water heater.
Check the manufacturers install guidelines. Either way thats too close, especially below that protrusion directly above (Bay or bow window?)
Terrill, when I had my, low to the ground, concentric vent changed to 2 vents, one intake and one exhaust, there were very specific measurements separating the two vents in the manufacturer’s installation instructions and they differed from the other manufacturers. I had it changed because the concentric vent got blocked by snow and shut down in the cold 7 PM of a wintery night and I had to figure what happened out fast as the temperature kept dropping fast. I finally saw the buried vent and dug it out and the furnace kicked on.
So, I would recommend Googling the make and model installation instructions and see what they say to get an accurate answer to your question.
Good luck and Happy Inspecting!!
Thanks, its a Carrier. I’ll check.
The things we deal with here in the North eh Larry:grin:
Isn’t that the truth, Scott!
