AN IMPORTANT MESSAGEABOUTRELININGYOUR CHIMNEY
1. Have a professional installer thoroughly clean, and install your new
appliance and relining system.
2. Determine condition of creosote buildup in masonry flue, always clean
before relining. Any tar glaze creosote buildup must be removed prior to
relining the chimney.
3. Determine condition of masonry fireplace and chimney. See that they
meet code requirements. The chimney should be checked for cracked, loose
or missing bricks, mortar, or other materials that could inhibit a correct
installation of the liner system. Make necessary repairs before relining.
4. The air space clearances between the masonry chimney exterior and
combustible materials should be checked to verify that the chimney is in
accordance with the clearance specifications of 1) the NFPA; 2) other
applicable building codes; or 3) these instructions (DuraLiner is approved
for 0” clearance if installed in accordance with these instructions).
5. Determine if your setup is an open hearth (Figure 1) or tee installation
(Figure 2). Also determine the available size of your chimney (Figure 2a)
and the corresponding allowable DuraLiner size. (Chart 2a)
6. If you have an open hearth setup, verify your flue size, and the fireplace
opening and depth before you purchase your appliance and reliner. (See
Figure 1)

Your fireplace insert or stove and DuraLiner are designed to work without
your existing damper. In order to install the DuraLiner, you must remove the
damper and in some cases part of the smoke shelf, to allow DuraLiner to pass
through this area freely. Note: DuraLiner flex pipe is available in both round
and oval shapes to ease installation.
Now that the old damper assembly and part of the smoke shelf has been
removed, the chimney and fireplace should be free from obstructions.
STEPTWO: The DuraLiner system is held in place by the framework at the
top of the chimney is designed to support the weight of a relining system up
to 50 feet. The minimum height of system must be at least 10-feet to insure
proper drafting performance.
The top comes assembled. You must take the top apart to get the bottom
frame in place. The top has six major components: Top, Screen, Secondary
Top, Frame, Slip Connector and Hanger. (See Figure 4) Place frame on top
of masonry chimney, the weight of the DuraLiner will hold the top in place.
We also provide screws that may be attached to bottom of frame and attached
tile. (See Figure 5).
STEP THREE: All DuraLiner pipe (flex and rigid) has male and female
connectorswith (4) pre-punched holesandslots that lineupand are connected
with stainless steel pop rivets. Do not use screws. When connecting sections
of flex pipe, it is necessary to first align the holes with the slots, and then drill
through the flex pipe with a 5/32” (4 mm) diameter twist drill bit. Next,
install the pop rivets. Drilling is not needed to connect sections of rigid pipe.
Connectfirst rigid sectionof DuraLinerontop offlex section with(4) stainless
steel pop rivets.
Note: The DuraLiner flex sections
can be easily insulated with the
Two-Ply Insulation Sleeve. This
blanket insulating sleeve permits
complete flexibility. It is held in
place by simple strap clamps that
aresecured withboltand nutat each

(NOTE: For improved draft and fire safety, we recommend the use of an
insulation sleeve on all flex pipes.)
After pipe is riveted together, lower through the Frame of DuraLiner Top and
hold in position. Each DuraLiner pipe section is then riveted and lowered
down the chimney. This procedure is repeated until the flex section reaches
the smoke shelf area. As the pipe is being lowered further down, bend the
flex pipe to fit through the damper. (See Figure 7a and 7b)
STEP FOUR: Before you rivet the last section of pipe in place, attach the
hanger to the last section of pipe just below the bead. (See Figure 8)
Attach the hanger strap holder to the last hole on the strap. (See Figure 8)

EXTEND-A-CAP INSTALLATION
The Extended-A-Cap is used with a DuraLiner
system when it is desired to extend the length
above the level of the existing masonry for the
purpose of improving draft, to accommodate
remodeling, to comply with safety requirements
for height of chimney above the roof, or as an
alternative to the Standard Termination.
Refer to the General Installation Instructions for
the majority of the installation. Extend-A-Cap
installationonly refers tothe top ofthe DuraLiner
installation, and is used instead of the Standard
Termination. All notes, warnings, maintenance
procedures, clearance, and basic instructions
containedinthe General Installation Instructions
are applicable to the Extend-A-Cap.

the storm collar, and seal with non-hardening sealant as shown in Figure 28.
STEPSIX: Install the cap, using #8 sheet metal screws, as shown in Fig. 28.
If the cap is 4-feet or more above the top of the masonry chimney, use an
extended roof bracket as shown in Fig. 29.
STEPSEVEN: Completethe connection of your stove orinsertas described
in STEP FIVE on pages 8, 9, and 10 of the General Installation Instructions.
The Maintenance Instructions contained on page 18 of these Installation
Instructions are all applicable to the Extend-A-Cap installation, other than
cap removal, which is accomplished by removing the four sheet metal screws
holding the band to the pipe section.
DuraLiner systems are designed solely for relining masonry chimneys,
therefore no clearances to combustibles have been established for these
systemsoutside of masonry chimneys. Inview of this,do not construct chases
or other enclosures around DuraLiner pipe sections which extend above the
masonry.

DURALINER MAINTENANCE INSTRUCTIONS
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
condenseon theinside ofthe chimneylinerduring slow-burningfiring periods.
Asaresult, creosote residue accumulatesonthe chimney liner. When ignited,
this creosote makes an extremely hot fire.
1. Access – Chimney liners must be installed so that access is provided for
inspection and cleaning.
2. When to Clean – The chimney liner should be inspected at least once
every two months during the heating season to determine if creosote or soot
buildup has occurred. Check spark arrestor screens every 2-4 weeks. If
creosote or soot has accumulated, it should be removed to reduce the risk of
chimney fire. At a minimum, the liner must be cleaned at least once a year.
3.How to Clean –Have your chimney linercleaned by aprofessionalcertified
chimneysweepif you have doubtsabout your ability to cleanit. Use a plastic,
wood, or flexible steel or wire brush. Do not use a brush that will mar the
stainless steel liner surface. Scrub the spark arrestor with a wire brush.
To remove the chimney cap for cleaning, unscrew the four screws that attach
the cap’s support legs to the cap base.
4. Coal – To reduce corrosion in chimneys where coal is burned, clean the
chimneythoroughly within 48hours of shuttingdownthe stoveforthe season.
Check the chimney’s lining for acid corrosion regularly.
5. 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 flue fire occurs, close all appliance draft openings and
call your Fire Department. Do not use the chimney again until it is inspected
for possible damage.
7.Flues – Connect onlyone solid fuel applianceperchimney liner. DuraLiner
shall be sized not less than that specified in the appliance manufacturer’s
instructions.
8.Appliance – Choose an appliance that is listed by a recognized testing and
listing agency and is not larger than you need.
