All-Fuel Chimney System
The DuraTech All-Fuel Chimney System
Designed for appliances that are tested and listed for use with a
2100° F HT chimney system.
DuraTech is a double-wall, all-fuel chimney system for use with wood stoves, replaces,
furnaces, boilers, ranges, water heaters, or other appliances fueled by wood, oil, coal, or gas,
and zero-clearance replaces that are factory-built.
With a Thermal Tech blanket
insulation encased between
dual walls, DuraTech offers
the optimum in safety and
performance. It keeps the
outer wall of the chimney
cool, while ensuring high
flue gas temperatures for
optimum
draft performance.
The inner wall is 20% thicker
than competitive chimneys for
an extra margin of safety. No
locking bands or mechanical
fasteners required.

framing. For tight installations,
a Reduced Clearance
Square Ceiling Support Box
is available (6” diameter
DuraTech only).

minute chimney fire tests at
