High-Temperature, Factory Insulated Double-Wall Masonry Relining system 5" Round 6", 8" Round and Oval DuraLiner Installation Instructions ®
A MAJOR CAUSE OF VENT RELATED FIRES IS FAILURE TO MAINTAIN REQUIRED CLEARANCES (AIR SPACES) TO COMBUSTIBLE MATERIALS. IT IS OF THE UTMOST IMPORTANCE THAT DURALINER BE INSTALLED ONLY IN ACCORDANCE WITH THESE INSTRUCTIONS. IMPORTANT: Read through all of these instructions before beginning your installation.

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 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).
From the appliance up through the damper area to the first flue tile, it is not mandatory to insulate flex pipe. Above the first flue tile, flex pipe must be insulated. NOTE: For improved draft and fire safety, we recommend ALL flex pipes be insulated (Fig.5)- (See "Installing Insulation" later in these instructions for detail). in this document). Note: If using an Oval pipe, this will need to be inserted prior to the plate.
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. Connect first rigid section of DuraLiner on top of flex section with (4) stainless steel pop rivets. Note: For insulating DuraLiner Flex, refer to the "Insulating Flex" Instruction section later in this document. Connector fits on top vented appliances with oval or rectangular openings. STEP FIVE: Connect appliance to DuraLiner. (Fig.
can be used to connect appliance to the tee using the pre-formed buttons for connection. The buttons snap into the branch ring. Slide appliance into proper position. Secure Adjustable Sleeve in final position with sheet metal screws. Rear flue exit should look like Fig.10. STEP SIX: Complete "Extend-A-Cap" termination. (Reference "Extend-A-Cap" instructions later in this document) clearance to the ceiling for single wall pipe is 18", and for DuraVent Close Clearance Connector (DVL) Pipe, 8" (Fig.12).
STEP THREE: Using DuraVent's Masonry Thimble with Slip Connector, connect slip connector to Tee Branch with the preformed buttons. Slide Masonry thimble to slip connector and attach black trim plate to masonry surface using screws. (Fig.13) MASONRY THIMBLE TEE ANCHOR SCREWS ACCESS DOOR FOR CLEANOUT SLIP CONNECTOR FROM MASONRY THIMBLE for the Wall Pass-Through to fit through the combustible wall. Again, before cutting this hole, check the clearance from the top of the Connector Pipe to the ceiling.
STEP FOUR: Push the Adjustable Sleeve from the Wall Pass Through into the branch of the tee. Connect Adjustable Sleeve to Tee Branch with the pre-formed buttons. Recommended to grout in place with a high temperature grout (Fig.15, Fig.16). STEP FIVE: Slide the Wall Pass-Through through the square trim plate and into the Adjustable Sleeve until the base of the Wall Pass Through is flush against the masonry (Fig.17) NOTE: The Wall Pass Through must protrude a minimum of 2" into the room (Fig.16).
Check the appliance manufacturer’s installation instructions to ensure proper positioning with relation to combustibles. EXTEND-A-CAP INSTALLATION Complete the installation with Connector Pipe Sections and Fittings as required. Inspect the completed job to ensure it is done in a careful and workman-like manner. STEP ONE: Center the base plate on the top of the masonry chimney (Fig.18). Trim to fit the chimney as required.
Do not construct chases or other enclosures around DuraLiner pipe sections which extend above the masonry. CAP AND SPARK ARRESTOR NOTE: MOISTURE MUST NOT ENTER THE LINER SYSTEM! STORM COLLAR CLAMP BASE and trim the blanket so that the flex end rings are exposed. Wrap the insulation around the liner lengthwise and trim it so that a butt joint is formed. Seal the joint with aluminum foil tape. Spray adhesive may be used to hold the blanket in place until it can be secured with the foil tape.
TRANSITION ANCHOR PLATE Ensure Round DuraLiner Pipe section will be within 12" of the top of the masonry. Secure Hanger to the top piece of DuraLiner pipe. Lower the Transition Anchor Plate (T.A.P) and allow the legs of the Hanger to slide through the oval slots in the T.A.P. Attach T.A.P. to the top of the existing masonry with field supplied hardware. If desired, a bead of 1000°F stove cement may be used as a gasket for this surface.
