Air for Combustion Ventilation and CARBON Introduction When the furnace is installed as a direct vent (2-pipe) furnace, no special provisions for air for combustion are required. However, other gas appliances installed in the space with the furnace may require outside air for combustion. Follow the guidelines below to insure that other gas appliances have sufficient air for combustion.
Indoor Combustion Air? NFPA & AGA Standard Methods and Known-Air-Infiltration and 2. Determine Rate minimum required volume for each total minimum required volume for the space. Table 4 Indoor combustion air is permitted for combustion, ventilation, and dilution, if the Standard or Known-Air-Infiltration Rate Method is used. - Minimum Space Volumes were determined by using the following equations from the National Fuel Gas Code ANSI 2223.1/NFPA 54-2009, 9.3.2.2: 1.
