We are finishing a basement that contains 1 furnace/AC and 1 Water Heater. We are enclosing the two units in a closet and are required to provide "make up" air for them. Rather than louvered doors for the closet we plan to install 2 transfer grills (return grills) in the wall of the closet that adjoins a large room, one high and one low- see drawing below.
My question is---What size grills will be sufficient to provide required make up air?
Furnace is 60,000BTU
W H is 40,000 BTU
Room that transfer grills will be in is 24' x 14' (total of 2700 Cu Ft)
