Do not fill the air space between the liner and chimney with loose fill insulation or cement. The Flexi-Liner and any Type "B" Gas Vent may be used in any combination desired to complete the system. When used as a Vent Connector, install with 1" (25mm) minimum airspace clearance to combustibles. At no time should an exposed portion of the Flexi-Liner be enclosed or pass through any combustible area or materials such as walls, ceilings, floors, roofs, attics, crawl spaces or joist areas as this product is not listed as Type "B" Gas Vent. Tools and Materials The following tools and materials are needed. Safety gloves Eye protection Ladder or scaffolding to reach the roof Masonry drill bits 1/2" or 3/8" High speed drill bit 3/8" Drill Hacksaw Screwdriver Hammer Pliers Cold chisel Tin snips Caulking exterior grade Small bag of mortar mix Trowel Mortar pan Piece of rope 10 feet longer than the chimney Use Type B Gas Vent or Flexi-Sleeve (sold separately) to minimize condensation and down-drafting, particularly if: a) The flue gas temperature is below 280°F at the entry point into the liner. b) Flexible Liner is to be installed in an exterior or oversized chimney. An exterior chimney has one or more sides exposed to the outdoors. c) The liner system is venting only fan-assisted appliances. d) The masonry chimney contains solid or liquid fuel residue from prior heating appliances. e) The appliance is equipped with a vent damper. Liner Components The following parts are available for liner installation: 15' Flexible Liner Kit (3" to 5" only) 25' Flexible Chimney Liner Kit 35' Flexible Chimney Liner Kit Kits includes applicable length of Flexible Liner, Support/ Flashing assembly, Round Top, Mortar Guard, screws and Installation Instructions. NOTE: The 5.5" flex kit also includes a 5.5" to 6" Flexible Connector. The following additional parts are available. Guide Cone (pull-down) 10' Extension Kit Flexible Connector B-Vent Adapter Flexible Sleeve Insulation CAUTION: Always wear gloves and eye protection during installation to avoid personal injury. Chimney Inspection and Cleaning Make sure the masonry chimney is sound in construction, clean and free from all loose and potentially flammable debris. If you find any cracked, loose or missing bricks or tiles, have them repaired or replaced. Before the installation of the liner, it is recommended that the chimney be cleaned by a certified chimney sweep. Since chimneys are usually very sooty and dusty, it is advisable to remove or cover your furniture, rugs etc. for the duration of the cleaning and installation of the liner. Chimney Preparation PREPARING FOR A STAND-ALONE APPLIANCE INSTALLATION If no opening currently exists, determine the location of the point where the vent system will penetrate the masonry wall, and prepare an opening through the masonry and any existing clay liner (with a masonry drill bit, cold chisel and hammer) large enough to accommodate the Mortar Guard, allowing for the Flexible Liner to exit the chimney opening. The opening must be located above the appliance outlet as high as possible to maximize connector rise yet maintain the proper clearances (see Figure 2a). It is recommended to install an inspection/cleanout door on the opposite side if conditions permit. Flexi-Liner® 3 Installation Instructions Break open existing mansonry chimney Locate opening above appliance Aluminum Flexible Chimney Liner and Gas Vent Connector PREPARING TOP OF CHIMNEY Your chimney may have a clay-tile liner that protrudes above the brick chimney. There is no need to remove the top portion of the clay tile liner if it is in good condition. You may want, at this time, to do any repairs to the chimney crown if any cracks or deterioration are showing. Once the repairs are done, follow the Flashing/Support Installation - Masonry Chimney section on page 5. If, on the other hand, the clay tile liner is not in good condition, you will need to make if flush by chipping away at the excess with a hammer, and cold chisel (see Figure 3). Make sure that pieces of the clay tile liner don't fall into the flue. When you have finished making the top of the chimney flush, fill in any cracks and uneven surfaces with mortar. Gas Stove Chimney Crown Clay tile above Chimney Crown Figure 2a Stand-Alone Appliance Clay Tile Liner PREPARING FOR AN INSERT Before installing the venting system, ensure that the damper plate is locked into the open position and secured or removed to prevent any damage to the liner (see Figure 2b). Note: Due to possible snagging, which may result in some surface damage, caution must be observed when lowering Linger lengths into the masonry flue. Flexible Liner Opened & Locked Damper Plate Masonry Chimney Figure 3 REMOVE CLAY TILE ABOVE CHIMNEY CROWN IF DAMAGE IS EVIDENT Liner Preparation DETERMINING LINER LENGTH Determine the required length of the liner by measuring the distance from the prepared opening to the top of the chimney, allowing for a 90-degree bend at the inlet. If the flexible liner will extend directly to the appliance, add the distance from the appliance exhaust collar to the prepared opening in the chimney flue, allowing for any required bends. Multiple lengths may be joined, using the Flexible Connector (see Figure 4). Figure 2b 4 Gas Fireplace Insert Slide Flexible Liner over the crimped end and secure with four (4) screws Figure 4 Flexible Connector Slide Flexible Liner over the crimped end and secure with four (4) screws Flexi-Liner® Aluminum Flexible Chimney Liner and Gas Vent Connector Installation Instructions TRIMMING THE LINER Select the leength(s) necessary to accommodate the required distance determined above. Stretch the Flexible Liner to the desired length (requires 2 people) by placing both hands around the circumference of the ends of the liner and gently pulling. If any Flexible Liner requires cutting, use a sharp fine-toothed hacksaw. Note: CAUTION: Do not attach the Flexible Connector and use it to stretch the liner. This may result in damage to the Flexible Liner. Due to possible snagging, which may result in some surface damage, caution must be observed when lowering Liner lengths into the masonry flue. Aflter feedind the liner down the chimney to the bottom, form a 90-degree bend and bring the Flexible liner through the prepared opening of the chimney wall (see Figure 6). GUIDE CONE (PULL-DOWN ASSEMBLY) A Guide Cone (Pull-Down) is available as an optional installation aide. When attached to a rope, it is used to pull and guide the end of the Flexible Liner through the chimney. With one end of the rope, simply tie a knot around the band of the Guide Cone. Attach the Guide Cone to the flex by sliding it over the Flexible Liner and inserting screws through the prepunched holes (see Figure 5). Once the Flexible Liner has been lowered in its final position, remove the Guide Cone. Flexible Liner Guide Cone/Pull-Down Flexible Liner Guide Cone/Pull-Down Band Knot Rope Figure 5 Screw through prepunched holes Rope Installing the Liner STAND-ALONE APPLIANCE Gather all necessary component parts and locate them near the termination of the chimney. This should consist of a Support/Flashing assembly, a Round Top, and the prepared length of Flexible Liner complete with Guide Cone and rope. Feed the Guide Cone and rope down the chimney flue (see Figure 6). While an assistant gently pulls on the rope from below, start lowering the Flexible Liner down into the chimney flue. If additional lengths of flex are required, join the sections together as the Flexible Liner progresses down the chimney. Flexi-Liner® Gas Appliance Figure 6 For the liner to extend directly to the appliance, continue to pull through the required amount of liner to allow a proper connection to the appliance exhaust collar. Any portion of liner used as a connector in a nearly horizontal orientation should include a minimum slope of 1/4" per foot upward from the appliance toward the chimney. 5 Aluminum Flexible Chimney Liner and Gas Vent Connector Encastrable Follow the Liner Preparation - Guide Cone (Pull-Down Assembly) section on page 4. Feed the liner down the chimney until it exits through the masonry fireplace opening (see Figure 7). Most gas fireplace inserts are equipped with a removable draft hood for easy flex to insert connection. Check the insert manufacturer's instructions for correct connection. Remove the Guide Cone from the Flexible Liner. Installation Instructions Round Top Prepunched Holes Flashing/Support Collar Flexible Liner Attach the Flexible Liner over the collar of the gas fireplace insert (check the appliance manufacturer's instructions for proper attachment). Once the insert is in its proper place, pull the excess Flexible Liner from the top of the chimney.

Position the Mortar Guard within the prepared opening, such that it will provide a protective barrier between the Liner and any required filler material. Refer to the Installation Completion section on page 8. Ensure that the end of the mortar Guard, with the Listing Label attached, extends into the room a minimum of 2" so that the label is visible for inspection. Appliance Connection Final connection of the flexible liner to the appliance may be made in a number of ways and will depend on specific conditions. TYPE B VENT CONNECTOR If Type B Vent is recommended as a connector (if clearances to combustibles or sizing guidelines suggest), the Flexible Liner should extend at least 2" (50mm) beyond the Mortar Guard. Figure 14 Type B Gas Vent Figure 15 Installation Instructions Masonry Chimney Flex Pipe B-Vent Adapter B-Vent Pipe Mortar Guard Self-Tap Screw(4 Typ.) Mortar Guard B-Vent Adapter B-Vent Pipe 1/4" Screws Figure 13 FLEXIBLE LINER B-VENT ADAPTER The Flexi-Liner universal B-Vent adapter connects Flexible Liner pipe to all brands of Type B Gas Vent pipe. To install: 1. Prior to installation, a Mortar Guard should be installed within the prepared opening, such that it will provide a protective barrrier between the liner and any required filler material. Ensure that the end of the Mortar Guard, with the listing label attached, extends into the room a minimum of 2" so that the label is visible for inspection (refer to main instructions for additional details). 8 Figure 16 Figure 17 Mortar Guard Install Self-Tap Screws B-Vent Adapter B-Vent Pipe Mortar Guard B-Vent Adapter B-Vent Pipe Flexi-Liner® Installation Instructions Aluminum Flexible Chimney Liner and Gas Vent Connector 2. The Flexible Liner should be installed such that it extends at least 2" beyond the Mortar Guard, allowing sufficient length for attaching the universal B Vent Adapter to the flex (see Figures 14 and 15). 3. Engage the outlet end of the universal B Vent Adapter with the flex pipe. Once fully engaged, secure the flex to the adapter using four (4) self-tapping sheet metal screws. Install the screws so that they penetrate through the flexible liner and the inner liner of the adapter (see Figure 16). 4. Engage the type B vent pipe with the universal B vent adapter. Once fully engages, tighten the machine screw so that the adapter clamps down and secures the B vent pipe in place (see Figure 17). 5. Refer to main instructions to complete installation. SINGLE-WALL VENT CONNECTOR PIPE Trim the Flexible Liner flush with the Mortar Guard. Insert the end of a single-wall vent connector pipe (by others) into the Flexible liner. Secure into place with four (4) evenly spaced screws through the Mortar Guard and into the Flexible Liner and the vent connector (see Figure 18). NOTE : The 5.5" - 6" flexible Connector is required when connecting 6" single-wall pipe to the 5.5" flexible liner. Installation Completion After the appliance is correctly positioned and all the venting connections are completed and checked for proper installation (clearances to combustibles, proper support and component parts), fill the void area around the penetration hole with mortar. High-temperature ceramic sealant or other noncombustible filler material may be used as a substitute instead of mortar. Final Inspection Ensure all gas piping, electrical, and vent connections are complete and up to code requirements. After adjusting the appliance and lighting the main burner, allow a couple of minutes for warm-up. Check the vent operation by holding a lighted match or smoking material just under the rim of the draft hoof relief opening. Proper venting will draw the flame or smoke into the draft hood. Imprper venting, indicated by escape or spillage of burned gas, will cause smoke to move away from the draft hood and a flame to flicker or go out. Liner Maintenance The Flexible Liner should be inspected by a qualified heating or chimney technician before each heating season to ensure it is free of debris and condensation and that all components are in good condition. This can be accomplished by removing the vent connector and looking into the liner at the base. Noncombustible Filler Material The Round Top can be removed for inspection purposes by removing the fastening screws. Again, have it inspected by a qualified heating or chimney technician. Reference Upon completion of the installation and if markings are not visible, fill in the supplied label and display adjacent to the liner inlet. Mortar Guard Figure 18 When used as a single-wall vent connector, and if it is acceptable, the flexible liner system may be extended all the way to the appliances and installed with 1" (25mm) airspace clearance to combustibles. Remember to include a minimum of 1/4" per foot rise in any horizontal sections (from the appliance to the chimney) and keep turns to a minimum (see Figure 18).

The a ir space around a n insta lled Flexi-Liner System must not be used to vent other a pplia nce s. A2. A Flexi-Liner System venting more tha n one appliance sha ll not be sma ller in diameter tha n the outlet of the la rgest a pplia nce being served. A3. For single a ppliance insta llations, the Flexi-Liner System ma y be sma ller in diameter tha n the outlet of the a pplia nce being served, providing: a ) the vent height is a t lea st 10ft. b) the liner size is not more tha n one size smaller. c) the "FAN MAX" is reduced by 10% if the a pplia nce is "fa n a ssisted". d) the outlet is la rger tha n 4" if the applia nce is "na tura l dra ft". A4. Reduce Flexi-Liner ca pa city for elbows (turns) a s follows: A4.1. Single Appliance (two 90º elbows for tota l vent system are fa ctored into cha rt) a ) In USA - for ea ch additiona l elbow up to 45º, reduce ca pacity by 5%. - for ea ch a dditiona l elbow 45º-90º, reduce ca pacity by 10%. b) In C DA - for ea ch a dditiona l elbow 90º reduce ca pa city by 10% for N AT a nd 15% for FAN. A4.2. Multiple Appliances (90º turn a t the bottom of liner is fa ctored into chart) a ) In USA - for ea ch elbow in the common vent up to 45º, reduce ca pacity by 5%. - for ea ch elbow 45º-90º, reduce ca pa city by 10%. b) In C DA - for each 90º elbow in the common vent, reduce ca pa city by 10% for N AT and 15% for FAN. Common Vent manifold fitting is part of the connector sizing coming to it. A5. Do not use these ta bles if the vent system contains any device (such as a vent da mper, dra ft regula tor or hea t recla imer, etc.), which reta rds the flow of vent ga ses. Refer to instructions provided by the ma nufa cturer of the device for vent instructions. A6. Interpola tion between the ta ble entries is permitted, extra pola tion beyond the ta ble entries is not permitted. A7. Vent connector sizes for multiple appliances are derived from tables included in the following national gas codes: NFPA 54 (USA) and B149.1 (CDA). A8. These tables are derived from the National Fuel Gas Code (NFPA 54 & CSA-B149). Current code data and information will supercede these sizing instructions if there is any discrepency between them.
