M&G DuraVent DuraLiner® - Manual (Page 5)

5
APPLICATION AND LISTING
DuraLiner is a double-wall, insulated all-
fuel reliner for masonry chimneys, used for
natural draft venting of gas, liquid and solid
fuel appliances. DuraLiner is listed to UL
1777 and ULC S635 under listing file number
MH14420, where maximum continuous
flue gas outlet temperatures do not exceed
1000°F/538°C (UL 1777) or 1200°F/650°C
(ULC S635). DuraLiner is approved for
installation with zero clearance between
the liner and masonry, plus zero clearance
between the masonry and combustibles.
When the Transition Anchor Plate is used,
Round DuraLiner pipe can be coupled to a
Duravent factory built 103HT chimney system
at the end of a masonry enclosure.
GENERAL INSTALLATION
INSTRUCTIONS
Follow both these and the appliance manufac-
turer’s instructions and manual for maximum
efficiency and safety. Connect only one flue
liner per appliance. DO NOT mix or match
with other products or improvise solutions-
(You may void warranties). DO NOT modify
parts.
Contact your local building official or fire
department regarding permits, restrictions,
and installation inspection in your area. Have
a professional installer thoroughly inspect (to
code requirements) and clean the existing
masonry flue of tar glaze creosote before
relining. The chimney should be checked
for cracked, loose or missing bricks, mortar,
or other materials that could inhibit correct
installation of the liner system. Make
necessary repairs prior to starting install.
Do not place insulation or other materials
other than specified in these instructions
around the liner or in required air spaces.
Determine if your setup is an open hearth
(Fig.1) or wall breach installation (Fig.2). Also
determine the available size of your chimney
and the corresponding allowable DuraLiner
size. (Fig.3)
• If you have an open hearth setup, verify
your flue size, and the fireplace opening
and depth before you purchase your
appliance and reliner.
• If you have a wall breach tee installation
setup, verify your flue size and chimney
height from tee, before you purchase your
appliance and reliner.
DuraLiner shall be sized not less than that
specified in the appliance manufacturer’s
instructions. Vent sizing is especially important
in areas with low ambient temps and low
temp flue products. Determine the required
size of DuraLiner and the correct Appliance
Connector (follow appliance manufacturer’s
recommendations). There are three different
types of appliances connections (Fig.4).
