Inspections:

All chimneys need annual inspections. Inspections cover not only whether or not a chimney needs cleaning but also safety and fire code compliance. Pictures from actually chimney scans that we have done are at the bottom of the page. A chimney scan is a Level 2 inspection.

The National Fire Protection Agency has created a nationwide standard for inspections, which has been adopted as part of the Fire Code for New Hampshire, which means that it must be followed by contractors, real estate agents, insurance providers, as well as homeowners. Quoted directly from the State Fire Marshal's web site:

"PART Saf-C 6013  CHIMNEYS, FIREPLACES, VENTS AND SOLID FUEL BURNING APPLIANCES

          Saf-C 6013.01  Model Code for the Installation and Operation of Solid Fuel Heating Appliances.  All persons installing, maintaining, repairing or operating solid fuel heating appliances shall comply with the requirements of NFPA 211."

 (The NFPA 211 is the basis for every state and town that has fire codes). The code recognizes 3 levels of inspection and the times that each inspection is appropriate. A Level I inspection is part of every cleaning that we do. A Level II inspection is required for Real Estate transactions or when changing appliances. We have the video scanning equipment for Level II inspections. A Level III inspection is the most thorough, and extreme, usually problems can be determined with a Level I or II. The NFPA 211 is below, if you have any questions as to what each type is, or what you need, please call us.

The NFPA Inspections Codes, directly quoted, with permission, NFPA 211Table 14.3.1 "Selection of inspection type":

Level I

Degree of Access Required: Readily accessible portions of chimney exterior and interior, accessible portions of appliance and chimney connection.

Circumstances: Annual inspection as required by Section 13.2; during routine cleaning of chimney flue, upon direct replacement of connected appliance with one of a similar type, input rating and efficiency.

Indications: For verification of suitability of the chimney for continued service, under the same conditions and with the same appliance or appliances


Level II

Scope: All subjects of a Level I inspection; proper construction and condition of accessible portions of the chimney structure and all enclosed flues; proper clearances from combustibles in accessible locations; size and suitability of flues for connected appliances.

Degree of Access Required: All accessible portions of the chimney exterior and interior, including areas within accessible attics, crawl spaces, and basements, and accessible portions of the appliance and chimney connection; includes inspection by video scanning or other means.

Circumstances: Upon addition or removal of one or more connected appliances or replacement of appliance with one of dissimilar type, input rating, or efficiency; prior to relining or replacement of flue lining; upon sale or transfer of the property; after operating malfunction or external event likely to have caused damage to the chimney.

Indications: For verification of suitability of the chimney for new or changed service; Level I inspection not sufficient to determine serviceability of the chimney

Level III

Scope: All subjects of Level I and Level II inspections, proper construction and condition of concealed portions of chimney structure and enclosed flues, proper clearances from combustibles.

Degree of Access Required: External and internal portions of chimney structure, including concealed areas of the building or chimney; includes the removal of components of building or chimney were necessary, but only as necessary to gain access to the areas that are the subject of the inspection.

Circumstances: Where necessary for the investigation of an incident that has caused damage to the chimney or building; where a hazard detected or suspected as the result of a Level I or Level II inspection cannot be fully evaluated without access to concealed areas.

Indications: When construction of all or part of chimney is deemed critical to its renewed or continued use; required only for those areas that cannot be properly evaluated by a Level I or Level II inspection.

The following pictures are from actual scans, which illustrates what can be found during a scan.
