NFPA 211 is the abbreviation for the National Fire Prevention Association's Standard for chimney and fireplace systems. The scope of work performed in the inspection or evaluation of a fireplace, stove or other venting system had previously been left to the discretion of the chimney service technician. On January 13, 2010, the National Fire Protection Association adopted these levels of inspection into code NFPA 211 (Standard for Chimneys, Fireplaces, Vents and Solid Fuel Burning Appliances) that remove much of that "discretion". Inspections are now clearly defined as Level 1, Level 2 or Level 3. NFPA 211 is the standard upon which certified chimney sweeps base their services and CSIA Certified Chimney Sweeps are tested to these three levels of inspection. Always ask for the level of inspection that you believe will be most appropriate for your chimney and venting system. Each level of inspection covers specific items depending on the individual appliance and venting system.
