NFPA 211
.

Must have at least 5/8 inch (16mm) fire clay lining
joined with refractory cement (Installations into a clay
flue without a stainless steel liner may reduce draw
which affects performance, will cause the glass to
darken and produce excessive creosote).

The masonry wall of the chimney, if brick or modular
block, must be a minimum of 4 inches (102mm)
nominal thickness.
• A chimney of rubble stone must be at least 12 inches
(305mm) thick.

It is recommended that chimneys with larger diameters
than 6 inches (152mm) be relined. An oversized flue can
affect draft and impair performance and will allow increased
build-up of creosote.
