When considering a masonry chimney,
round tiles are preferable to square or
rectangular, as round tiles have much
better airflow characteristics and are far
easier to clean. Unfortunately, most
North American chimneys use square or
rectangular tile liners that are really de-
signed for open fireplaces, not stoves or
furnaces. Of most importance, second
only to overall chimney height, is the
diameter of the flue liner itself. In most
instances, it should be sized to the appli-
ance; i.e., 6" flue outlet on the appliance
requires a 6" flue. The inner diameter
should never be less than the flue outlet
diameter and should never be greater
than 50% of the appliance flue outlet. For
example, do not expect a wood burning
stove or furnace to function properly if
installed into a chimney with a flue liner
greater than 50% the appliance outlet -
- such as a 6" flue outlet requires a 6"
diameter for optimum drafting, but can
function well with an 8", but becomes
borderline beyond 8" diameter.
Masonry chimneys built of concrete
blocks without flue liners of at least 5/8"
fireclay do not meet modern building
codes. A

solid fuel appliance must not be joined
to a chimney flue which is connected to
another appliance burning other fuels.
If your chimney has a typically oversized
flue liner of 8x12 inches or greater, or if it
is unlined, it will be necessary for you to
reline the chimney, using many of the
modern approved and economical meth-
ods such as stainless steel, castable
refractory, or properly sized fireclay lin-
ings.
