APPLICATION AND LISTING
DuraLiner is a double-wall, insulated allfuel 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 le number
MH14420, where maximum continuous
ue 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 manufacturer’s instructions and manual for maximum
efciency and safety. Connect only one ue
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 ofcial or re
department regarding permits, restrictions,
and installation inspection in your area. Have
a professional installer thoroughly inspect (to
code requirements) and clean the existing
masonry ue 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 specied 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 ue size, and the replace opening
and depth before you purchase your
appliance and reliner.
• If you have a wall breach tee installation
setup, verify your ue size and chimney
height from tee, before you purchase your
appliance and reliner.
DuraLiner shall be sized not less than that
specied in the appliance manufacturer’s
instructions. Vent sizing is especially important
in areas with low ambient temps and low
temp ue 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).

Combustible Wall and Masonry
(See completed installation in Fig.15)
STEP ONE: If no hole exists in the masonry,
mark the center point for the location of
penetration into the combustible wall. Before
cutting or drilling, check the clearance between
the top of the connecting pipe to the ceiling,
as shown in Fig.12, Fig.15. The minimum
clearance to the ceiling for single wall pipe is
18", and for DuraVent DVL Connector Pipe, 8".
Scribe a circle from the center point on the wall
with a 7-1/4 inch radius (14-1/2 inch diameter)
(Fig.14). This is the size of the hole required
for the Wall Pass-Through to t through the
combustible wall. Again, before cutting this
hole, check the clearance from the top of the
Connector Pipe to the ceiling.
STEP TWO: If the minimum clearance to the
combustible ceiling is met, then drill a 3/8 inch
diameter hole through the combustible wall, at
the center of the 14-1/2 inch circle you have
inscribed. With a punch, mark the center on
the masonry behind the wall. Cut the 14-1/2
inch diameter hole in the wall. If it is necessary
to cut through studs, additional framing should
be installed to maintain the structural integrity
of the wall (Fig.14).

STEP ONE: Center the base plate on the top
of the masonry chimney (Fig.18). Trim to t
the chimney as required. Use non-hardening
sealant to seal the base plate to the masonry
chimney, but this can be done after the liner
has been lowered into place. Anchors or
screws are recommended but not required, as
the base plate will ultimately be supporting the
entire weight of the installation.
STEP TWO: Assemble and position the clamp
assembly on top of the base (Fig.6, Fig.18).
Adjust the bolts on the clamp assembly so that
pipe sections will just pass through the clamp.
STEP THREE: Once the desired length of
liner has been achieved, tighten the clamp
assembly bolts, until the system is rmly
supported by the base. There should not be a
Duraliner pipe joint above the clamp assembly.
Attach the storm collar, and seal with nonhardening silicone (500°F) sealant. Install Cap

DURALINER MAINTENANCE
- Creosote and Soot-Formation and Need
for Removal: When wood is burned slowly,
it produces tar and other organic vapors,
which combine with expelled moisture to
form creosote. The creosote vapors may
condense on the inside of the chimney liner
during slow-burning ring periods. As a result,
creosote residue accumulates on the chimney
liner. When ignited, this creosote makes an
extremely hot re.
- The chimney liner system should be
inspected at least once every two months
during the heating season to determine if a
creosote or soot buildup (3mm or more) has
occurred. The spark arrestor screen should
be checked more frequently. If creosote or
soot has accumulated, it should be removed to
reduce the risk of a chimney re.
1. Access – Chimney liners must be installed
to provide access for inspection and cleaning.
2. How to Clean – Recommend to have
your chimney liner cleaned by a professional
certied chimney sweep. Use a plastic, wood,
or exible steel or wire brush- do not mar the
stainless steel liner surface. To remove the
chimney cap for cleaning, unscrew the four
screws that attach the cap’s support legs to the
cap base.
3. Coal – Clean the chimney thoroughly within
48 hours of shutting down the appliance for the
season. Check the chimney for acid corrosion
regularly.
4. No Chemical Cleaners – Do not use
chemical chimney cleaners. Their use does
not eliminate the need for mechanical cleaning
and they may be highly corrosive.
6. In case of Fire – If a ue re occurs, close
all appliance draft openings and call your Fire
Department. Do not use the chimney again
until it is inspected for possible damage.
