STOVEPIPE
It is recommended that overall Eue connecting
pipe length be kept to a minimum. Any horizontal
runs must slope upward towards the chimney, with
a minimum rise of 1/4 inch per foot. Use a minimum
number of elbows, preferably no more than two, to
make the chimney connection.
Particular a=ention should be paid to the point
where a Eue passes through a wall or ceiling.
pass-thru should always be made with insulated
pipe and the proper accessories or use of a thimble
that provides a diameter of not less than three times
the diameter of the stovepipe. If the chimney must
go through a combustible wall, be sure to use a
metal thimble specially designed for this purpose.
e proper way to install a thimble is to cut an
oversize hole in the sheetrock about 6 or 7 inches
larger than the thimble. However, be sure to follow
the manufacturer's directions that come with the
thimble. A metal ring shield is used to cover the
hole.
is way air can circulate and cool the area
around the passageway.
Note: Do not decrease the diameter of chimney
pipe to less than that of the flue collar! Chimney
connector and flue must be 8 inches in diameter
or greater.
Inspect stove pipe at least twice
monthly for creosote buildup.
Creosote creates a risk of chimney
fire, and can obstruct stove pipe. An
obstructed stove pipe can result in
CO buildup in your boiler room.
Fires of low intensity, or low smoldering 9res are
likely to produce creosote buildup. Tars and other
organic vapors combine with moisture from the fuel
and from combustion byproducts to form creosote.
e more time the boiler is 9red with wood at low
9re, the more opportunity for buildup of creosote
inside the stove pipe and chimney. Inspect at least
twice monthly, and remove if buildup occurs.
Prevention is your best option, but if creosote is
observed, a coal 9re will serve to dry up the
creosote, a;er which it can be removed manually
from the chimney and stove pipe with the
appropriately sized cleaning brushes.
e
Manual Dampers must not be
installed in the flue pipe. Improper
operation could result in death.
Stove pipe passing through wall
Use 24 gauge or heavier single wall stove pipe in
open areas no closer than 18 inches from walls or
ceiling. If the stovepipe must be closer than 18
inches from the nearest wall or ceiling, or if it must
go through walls, closets, or boxed in areas, then UL
listed insulated stovepipe must be used. Pipe that
runs along the outside walls of a building must also
be UL listed insulated pipe, even if it runs along a
non-combustible outside wall.
in place in order to prevent cooling of the stovepipe
which in turn cools the rising smoke and causes
creosote to form quickly.

Wall Pass-Through: United States
In the U.S., the national code is NFPA 211. While
many localities adopt this standard, be sure to check
with local authorities before beginning your
installation.
