It is installed as a 100% loss system, there is no cold air return from the heated area. I did it this way so I could keep positive pressure in the room. I exhaust the air through a filtered man door opening.

I have considered putting a return duct between the furnace room and the garage for just heating in cold weather. I would put a sealed door on this opening so I could close it for painting.
Best one yet! I like keeping furnaces and compressors away from my work area when possible.
