CHIMNEY CONNECTION
Two basic types of chimneys are ap-
proved for use with solid fuel: Factory-
built and masonry. Factory-built chim-
ney must comply with UL103HT stan-
dard.
Do not expect your stove or furnace to
create draft. Draft is not a function of the
appliance. Draft is purely a function of the
chimney. Modern stoves and furnaces
are much more airtight and efficient than
those of the past; and, therefore require
greater draft. A minimum of .05, mea-
sured in water column (gauges to mea-
sure chimney draft are readily available
at stove shops and are economical to
purchase or rent) is required for proper
drafting to prevent back-puffing, smoke
spillage, and to maximize performance.
Chimneys perform two functions - one of
which is apparent: The chimney pro-
vides a means for exhausting smoke and
flue

gases resulting from combustion of the
fuel. Secondarily, though, the chimney
provides "Draft" which allows oxygen to
be continuously introduced into the
appliance, so that proper combustion is
possible. As of April 1, 1987, all heaters
and furnaces manufactured by United
States Stove Company should be
installed using a factory built chimney
that meets the "Type HT" requirement of
UL 103 (when a factory - built chimney is
used).
*Size the chimney to the flue outlet on the
stove. (6" outlet = 6" I.D. chimney)
*Avoid using elbows except as necessary
(they reduce draft).
*Make sure all horizontal runs of
connector pipe go up hill (1/4" elevation
for each horizontal foot).
