between DuraTech Chimney Pipe and any
combustible materials. Never fill any required
clearance space with insulation or any other
materials. Combustible materials include
lumber, plywood, sheetrock, plaster and lath,
furniture, curtains, electrical wiring and building
insulation. Keep single wall stovepipe at least
18 inches away from combustible materials,
unless a clearance reduction system that is
acceptable to the authority having jurisdiction
is used, or the appliance to be installed is
listed and the instructions specify a different
clearance.

DURATECH CHIMNEY
APPLICATIONS
DuraTech Chimney (5”-8” Dia) is a complete
chimney system tested and listed to UL 103
HT for the United States, and ULC S604
in Canada. In the U.S., DuraTech 5”-8”
Chimney can be used with wood stoves,
fireplaces, fireboxes, furnaces, boilers, or
other residential-type appliances fueled by oil,
gas, coal, or wood, that require a UL103 HT
chimney system. In Canada, DuraTech can
be used with oil & gas fired appliances listed
for use with a Type A Chimney, in accordance
with ULC S604 . DuraTech is also listed for use
in Canada with some factory-built fireplaces;
check with your fireplace manufacturer.
Otherwise, DuraTech has not been approved
for use with solid fuel appliances in Canada.
Do not use with forced draft, positive-pressure
appliances. The DuraTech Chimney system
may have a maximum of two (2) offsets (four
elbows total) of 30° from vertical. DuraTech
Chimney is listed under UL FIle MH7399.
INSTALLATION NOTES
You must use only authorized DuraTech
Chimney parts to maintain a listed Chimney
system (not including the connector pipe).
Do not mix parts or try to match with other
products, or use improvised solutions. Do
not install damaged or modified parts. Follow
the appliance manufacturer’s instructions to
determine: chimney diameter, clearances
between combustible materials and your
heating appliance, and to ensure maximum
system efficiency and safety. Connect only
one appliance per chimney. Never choose
a chimney with an inside diameter smaller
than your appliance’s outlet. Practice good
workmanship, sloppy work could jeopardize
your chimney’s safety. Keep electrical wiring
and insulation away from all chimneys and
stovepipes. If you have any questions, be
sure to contact either your dealer or DuraVent
directly.
Fuels: Do not burn driftwood, plastic, or
chemically treated wood such as railroad
ties. They are corrosive to your appliance,
stovepipe and chimney. Follow the appliance
manufacturer’s instructions and safety manual
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 overfiring, 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.
