Section Ii: Masonry Insert Installation - New Buck Corporation 21 Manual

The Model 21 may be installed using an all masonry fireplace built in accordance with the
Uniform Building Code and National Fire Protection Association (NFPA). The first step in
this type of installation is to determine the acceptability of the fireplace and chimney for use
with a woodstove. Both the construction and condition of the fireplace are important consid-
erations when installing a woodstove. The chimney should extend at least 3' above the roof
and at least 2' above any point of the roof within 10'.

CHIMNEY FLUE SERVING ANOTHER APPLIANCE."
