General Electric was marketing its 1,200-cfm range hoods to residential customers. In fact, a GE Monogram press release bragged that the appliance could be installed anywhere: “The ventilation system operates at maximum venting capacity of 1,200 cubic feet per minute to keep the kitchen free of fumes and odors. Beautifully finished on all sides, the new Monogram island hood lends elegance to any kitchen.”
ASHRAE’s residential ventilation standard, ASHRAE 62.2, limits exhaust fans to a maximum of 15 cfm per 100 square feet of occupiable space, unless a backdrafting test is performed. According to this standard, the smallest home in which a 1,200-cfm range hood could be installed without verifying makeup air needs would be one measuring 8,000 square feet — a very large McMansion indeed.
Moreover, in a house with an atmospherically vented water heater, a 1,200-cfm GE Monogram range hood may cause backdrafting of flue gases, even if the water heater was originally installed in compliance with NFPA and ASHRAE standards. So complying with these standards for water-heater installation won’t keep you out of trouble.
