Black iron
If the volume of space where the appliance is located is less than 50 cubic feet of space per......BTU per hour of aggregate input of the appliance, then it is a confined space. - - 50 cubic feet = 2.5 feet x 2.5 feet x 8 feet - - In unconfined spaces in buildings, infiltration may be adequate to provide air for combustion, ventilation and dilution of flue gases. However, in buildings of tight construction -- for example, doors and windows that have weatherstripping, walls that are heavily insulated, openings that are caulked, floors and walls with vapor barriers, etc. -- additional air may need to be provided. - - Solution - - Two permanent openings to adjacent spaces could be provided so that the combined volume of all spaces meets the requirements. If the building is sealed so tightly that infiltration air is not adequate for combustion, combustion air should then be obtained from outdoors. - 1,000
