CONNECTING SMOKE PIPE
Set the smoke pipe end of the furnace as close to
the chimney as possible. For every foot of lateral
pipe, the rise of the smoke pipe toward the chimney
must be at least one inch. Do not exceed 10 feet in
length and no more than 2 elbows. A Clean out tee
should be installed for removal of soot and fly ash.
Do not install the smoke pipe longer than necessary
to reach the chimney for purposes of trapping heat.
The smoke outlet temperature is designed so that
the heat emitted is needed to carry the by-products
of combustion out through the chimney.
The smoke pipe must not pass through any combus-
tible material.
The smoke pipe entrance into a masonry chimney
should be at least 2 feet above the clean out. The
smoke pipe must not extend into the chimney
beyond the inner face of the chimney liner.
CAUTION:
DO NOT USE ANY SMOKE PIPES LESS THAN 24
GAUGE BETWEEN FURNACE AND CHIMNEY.
WARNING
Check your chimney. The chimney is a very important part of your
heating system. It must be the right size, properly constructed and in
good condition. No furnace can function properly with a bad chimney.
The chimney must supply a draft of .03 Water Column. If possible, use
a 15 foot or higher chimney. Add an additional foot to the chimney for
each 1,000 feet of elevation above sea level.
