Further to my last,,, It is a Keeprite 80BTU,, Horizontal (left or right only). Multi position furnaces were not tearing up the market at that time. The Induced Draft Fan must be mounted above burner, This one is not. Also notice the flue vent,,, attached in such as way at to vent upwards, but in no way anywhere close to manufacturers instruction,,, this installation was done by a couple of guys in a volkswagen showing up with all their tools still in the packaging,, and not having a clue,, but probably got the cheque off the customer. Why was it never inspected?,, Because the inspector for the utility is not about to go up into a crawl space or attic when his waist measurements exceed the size of the hatch.
