in regards to fuels. Not all appliances are
equipped to burn coal. Coal with a low sulfur
content will reduce the possibility of corrosion.
Care must be taken to avoid over-ring, which
can damage the appliance, stovepipe and
chimney system.
Mobile Homes: Please read the appliance
manufacturer’s instructions and safety manual
carefully. Not all appliances are listed for use
in mobile homes.
CHIMNEY HEIGHT
The National Fire Protection Association
Standard #211 states: “Chimneys shall extend
at least three feet above the highest point
where it passes through the roof of a building,
and at least two feet higher than any portion
of a building within ten feet.” (Fig.1) DuraTech
Chimney may be installed up to 60 feet high. If
the chimney extends more than 5 feet above
the roof, an Extended Roof Bracket must be
used (see page 12). Due to the overlap of the
joints, subtract 1-1/4 inches from each Chimney
Section’s height to calculate installed height.
CHIMNEY PLACEMENT
When deciding the location of your chimney,
try to avoid modications to roof beams and
other structural components of the building.
CHIMNEY ENCLOSURE REQUIRE-
MENTS
Through Rooms: Interior chimneys shall be
enclosed where they extend through closets,
storage areas, occupied spaces, or any place
the surface of the chimney could be contacted
by persons or combustible materials. Maintain
at least a 2-inches of clearance between the
outer wall of the chimney and the enclosure
(Fig.2).
