1.5.4
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.
