Class-A Chimney System
by M&G Dura-Vent
THE ULTIMATE CLASS-A CHIMNEY SYSTEM
Now FULLY warranted to the Internet purchaser
by Hart’s Hearth Inc.!!!
Talk about innovation - DuraTech sets a whole new standard in qualitydesign,
and performance for chimney systems.
Using a compressed blanket insulation, DuraTech keeps the outer wall of the
chimney cool while ensuring high flue gas temperatures for optimum draft
Encased between dual walls of stainless steel, Thermal Tech blanket
insulation is locked into position. This eliminates hot spots common with loose-fill
type insulation. No sifting, settling, or dangerous voids.
In the event of a creosote fire, compressible blanket insulation permits the
chimney liners to expand outward in a radial direction. DuraTech's free floating
inner liner design also permits the liner to expand in a lengthwise direction. This
eliminates buckling and loss of structural integrity associated with solid-pack
DuraTech Chimney is available in 5", 6", 7", and 8" diameters in 6", 12", 18",
24", 36", and 48" lengths. And in 10" and 12" diameter it is available in 12", 24",
and 36" lengths. We also carry, on a special order basis, 14" and 16" diameter
chimney. Note: We are referring to inner diameters here. Outer diameter is 2"
DuraTech 2100° Chimney has been tested and listed to the UL 103 HT
standard, UL File #MH7399. Designed for normal continuous operation at 1000°
F flue gas temperatures, DuraTech (5" - 8" diameters) has been subjected to
rigorous and stringent UL testing including one hour at 1400° F, plus three ten-
minute chimney fire tests at 2100° F. DuraTech 1700° F Chimney (10", 12", 14",

CHECK OUT THE FEATURES AND BENEFITS OF OUR UL-
LISTED DURATECH CHIMNEY:
Here's how DuraTech stacks up against SuperPro, Security, and Excel Chimney.
Twist-lock construction. No need for mechanical fasteners, DuraTech
has the advantage over Excel Chimney here. (10" - 16" ID fasten together with
Fully encased insulation. Excel doesn't have it. And with DuraTech
there is no dealing with parts coated with insulation dust as with SuperPro
or Security. Wow!
Swivel Elbows. Only DuraTech has 'em. When you have to go around
obstructions like rafters, ridge poles, or joists, you've got to use elbows. But
rigid elbows can really mess up your planned termination point for the
chimney. Well with DuraTech's Swivel Elbows, you can swivel the base of
the elbow to make things come out right.
Weight. DuraTech is half the weight of SuperPro or Security making it
easier to install.
Made in the USA. DuraTech is proudly made in Vacaville, CA.. American
craftsmanship at its best!
DuraTech wins hands down. All of these great features and benefits
qualify DuraTech as the best class-A chimney on the market. Nothing
compares to it . Nothing.
There is however one huge problem with DuraVent's
DuraTech; M&G DuraVent refuses to warrant the product if
it is installed by a D.I.Y.er like most of our customers are.

and M&G DuraVent’s relining products including DuraLiner®,
DuraFlex® (SW, Pro, 316, 304), and Ventinox®."
