(4) Each warm air furnace and packaged boiler manufactured on or after January 1, 1994, shall meet the following standard levels: "(A) The minimum thermal efficiency at the maximum rated capacity of gas-fired warm-air furnaces with capacity of 225,000 Btu per hour or more shall be 80 percent. "(B) The minimum thermal efficiency at the maximum rated capacity of oil-fired warm-air furnaces with capacity of 225,000 Btu per hour or more shall be 81 percent. "(C) The minimum combustion efficiency at the maximum rated capacity of gas-fired packaged boilers with capacity of 300,000 Btu per hour or more shall be 80 percent. "(D) The minimum combustion efficiency at the maximum rated capacity of oil-fired packaged boilers with capacity of 300,000 Btu per hour or more shallbe 83 percent. "(5) Each storage water heater, instantaneous water heater, and unfired water storage tank manufactured on or after January 1, 1994, shall meet the following standard levels: "(A) Except as providea in subparagraph (G), the maximum standby loss, in percent per hour, of electric storage water heaters shall be 0.30 + (27/Measured Storage Volume [in gallons]).
