Input To Furnace (Btu/hr)
Cubic Feet Per Hour Required =
Heating Value of Gas (Btu/Cu. Ft.)
NOTE: The cubic feet per hour listed in the table above must be greater than the cubic feet
per hour of gas flow required by the furnace. To determine the cubic feet per hour of gas flow
required by the furnace, divide the input rate of the furnace by the heating value (from gas
supplier) of the gas.
