96% furnace. The air intake was not directed and terminated outside as the old furnace was. The installer said that over the years it has been determined that the inside basement air is better for the furnace. Outside air intake is now old school. The pipe was there from the old furnace. I’m not sure why they didn’t reattach it( instead cut it off ). Also there isn’t any name plate on the furnace. Installer said that happens at the factory. Many brands come off the same line. I looked inside for serial a number / date tag and found nothing. Seems like there is always something around the burner box area. Outside the furnace on the side is a model number G96vtn1002130a enter image description here
The other intake pipe appears to be capped. With no direct air inlet and the old line capped this sets up problems including code compliance issues.
I would verify with a local building code inspector, I don’t do furnaces full time but that would not pass inspection in my jurisdiction, to me it looks like a lazy installer trying to save a buck.
So my answer is NO it is not right. it should have a fresh air source.
