WebJan 9, 2024 · Horizontal duct opening – One-inch free area for each 2,000 BTU/hr input of gas-burning appliances in the room. Mechanical fan – One CFM of air for each 2,400 BTU/hr input of gas-burning appliances in the room. Indoor air – 50 cubic ft. of volume for each 1,000 BTU/hr of the appliances. WebA furnace return system must collect all the air being put out by that system. If the furnace is putting out 1,000 cubic feet per minute of air flow, the return system must collect 1,000 cubic feet and take it back to the unit. An insufficient return system or one too large will reduce the efficiency of the heating and increase energy bills.
