The DM80 is a dual (2) flue system with 8" diameters in
one outer casing. It is used for venting 2
appliances (one flue for each appliance, as specified
per building codes).
Example 1: Hook up a
furnace in the basement and a wood, pellet or coal stove
on the first floor.
Example 2: Two wood
stoves, one (appliance) for each flue.
The DM80 is NOT to be used on any of Isokern's
fireboxes.
All uses of the DM80 require a concrete footing - the
depth of which to be determined by a local building
official (for example, the frost line in New England is
4 feet below grade).
The proprietary double inner flue liner and outer
casing will allow expansion without cracking and
supersedes the Standard Testing for UL 103HT (High
Temperature). Isokern's many years of experience
using pumice also guarantees high R (insulation) values
and offers "zero clearance" for ease of installation.
The registered design of the DM system consists of
separate outer casings and inner flue blocks, which
allows for vertical and horizontal thermal expansion.
The tongue and groove construction paired with the
staggered joints provides maximum security against
escaping smoke and Carbon Dioxide gasses.
All of our chimney systems have a Brick Ledge option,
as well as Concrete pre-fab Caps.
Isokern gives a 10 year warranty on production and
fabrication with proof of semi-annual cleaning.
