TYPICAL TYPES OF CHIMNEY SYSTEMS
There are basically two types of chimney systems; one employs an existing masonry
chimney, while the other employs a manufactured or factory built chimney. In either system
the chimney may be of an interior or an exterior type. The following illustrations are provided
to demonstrate the basic components required for a proper and safe installation. The
components identified may not appear exactly as those purchased – the manufacturers’
installation instructions and specified clearance distances should always be followed in
accordance with local and national installation codes. In Canada the CSA B365 and the CSA
C22.1 installation codes are to be followed. In the USA the ANSI NFPA 70 and ANSI NFPA
211 installation codes are to be followed.
