CLEARANCES
Always allow at least a 2-inch clearance
between DuraTech Chimney Pipe and any
combustible 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.
NON-COMBUSTIBLE INSULATIONS
Non-combustible insulation is tested and
approved through UL for use within the
clearance to combustibles distance between
a passthrough leading to the exterior of a
building, and only as described in these
instructions. The non-combustible insulation
used must be listed / compliant with ASTM
E136/ULC S114 as non-combustible, have a
melting temperature above 2000°F/1100°C,
be water resistant with low mositure absorbtion
and be acceptable to the AHJ. Acceptable
insulations include those made from stone
(aka “rockwool” or “mineral wool” insulations).
Note - Fiberglass insulation is NOT
approved!

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,
replaces, reboxes, 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 red 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 replaces;
check with your replace manufacturer. 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.
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 modied parts. Follow
the appliance manufacturer’s instructions to
determine: chimney diameter, clearances
between combustible materials and your
heating appliance, and to ensure maximum
system efciency 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
