4.1.5 TYPICAL EXISTING MASONRY
You can also install your appliance using your
existing masonry chimney. To do so, follow the
guidelines below. Use a factory-built thimble,
or construct your own brick thimble. If you are
using a masonry chimney, it is important that it
be built in compliance with the specifi cations
of the Building Code in your region. It must
normally be lined with fi re clay bricks, metal
or clay tiles sealed together with fi re cement.
(Round fl ues are the most effi cient). The
maximum fl ue size is 8” (203.2mm) x 8”
(203.2mm) square or 6” (152.4mm) round.
For greater diameters it is necessary to
install a 6” stainless steel liner.
