Barametric Draft Damper

Specific Inspection Topics Inspecting HVAC Systems

Saw this one today. This is an oil fired downdraft hot air furnace. The house is a slab construction with the supply ducts running in the slab. Built in 1958.

The picture shows (if I can get it to load) the return air intake on the top of the furnace, 6" from the barometric draft damper opening.

Anyone think that this might be too close?!

Most certainly. . .

If I remember right, any return air in the same room within 10’ of the furnace is too close.

Absolutely wrong…and dangerous!!

The return should never be in the same closet with the barometric or draft diverter.
