The DM44 has an 8" inside diameter and is a high
performance flue system. It can be used for:
- wood stoves
- pellet stoves
- oil furnaces
- oil hot water heaters
- field assembled Isokern 28" Patio Series
fireplace
or any single appliance with a maximum diameter of 8"
vent.
The DM44 is NOT to be used on any of Isokern's
fireboxes.
All uses of the DM44 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.
