This class includes, generally, apparatus for the application of heat. It comprises cooking and heating stoves, hot-air furnaces, and accessories; hot-air radiators and heating drums; open water heaters, steaming apparatus, dampers, fireplaces, and stovepipes. It includes the fuel burner when combined with the stove or furnace structure; combinations of a particular stove or furnace structure of the type classified in this class (126) with a closed water heater or steam generator; water heaters of only the nonpressure type unless they are structurally tied to the stove or furnace or form a necessary part thereof, and grates of general use in stoves, hot-air furnaces, or boiler furnaces.
