NOTE: The cubic feet per hour listed in the table above must be greater than the cubic feet per hour of gas fl ow required by
the furnace. To determine the cubic feet per hour of gas fl ow required by the furnace, divide the input rate of the furnace by
the heating value (from gas supplier) of the gas.
