PRODUCT INFORMATION

Stainless Steel Flexible Liner is designed and listed to be installed within masonry chimneys used to vent the products of combustion produced by heating appliances that burn oil, gas, or solid fuels. This liner should be installed by professionals who are certified in the U.S. by NFI (National Fireplace Institute) or in Canada by WETT (Wood Energy Technology Transfer Inc.). Stainless Steel Flexible Liner is intended for residential type appliances (including fireplace insert) and building heating appliances in which the maximum continuous flue gas outlet temperatures do not normally exceed 1200 o F (650  o C) in Canada and 1000 o F (540  oC) in the United States.
Stainless Steel Flexible Liner is not intended for use with Category II, III or IV gas burning appliances or other appliances that cause condensation of corrosive acids on the liner of the chimney or create positive pressures in the chimney system.
Do not connect any appliance that burns a liquid fuel to a chimney liner used to vent a solid fuel burning appliance.
Stainless Steel Flexible Liner, Top Plate and Rain Cap are constructed of 300 series stainless steel. These components have a built-in worm screw fastening hose clamp as a securing system. Each installation must be planned for the best performance of the appliance being installed. Refer to appliance manufacturer’s instructions to determine any special venting requirements for specific appliance. Building permits may be required before installation. Do not use any materials or components other than specified in these installation instructions. The installer must contact the local building and fire code officials to determine any installation and inspection requirements. Building permits may be required before installation. Liner must be installed within the local building codes. Please remember, regardless of national codes, the local building inspectors have ultimate jurisdiction.

TOOLS AND MATERIALS

The following tools and materials may be required as well as some others depending on the location and structure of the chimney:

Safety Work Gloves Dust Respirator (3M 9900 or equiv.)

INSPECTION AND PREPARATION OF CHIMNEY

The existing chimney must meet the following codes for proper construction and compliance requirements before the liner can be installed:
– The chimney must have the proper wall thickness, ie: minimum of 4 inches (nominal) solid masonry units or as required by local building codes.
– Before the installation of the liner, the chimney and the smoke chamber of the fireplace must be cleaned thoroughly by a certified chimney sweep to remove all deposits of soot, creosote, or glazed creosote. Failure to thoroughly clean the chimney before installing a new liner system may lead to fire and or smoke damage to the home.
– A proper inspection must be done to determine that the chimney is structurally sound. If the structural integrity of the chimney is found to be in question, ie: missing, loose, or craked masonry or mortar joints, repairs must be made before installation of the chimney liner.

– The chimney must be a minimum of 10 feet high, and a maximum of a 100 feet in height.
– Authorities require that the masonry chimney extend not less than 3 feet above the highest point where it passes through the roof of a building and not less than 2 feet above any portion of the building within ten feet (see FIGURE 1).

SIZING THE PROPER LINER DIAMETER

– A new masonry or concrete chimney must comply with the following codes; National Building Code, CAN/CSA A405 Standard for “Design and Construction of Masonry Chimneys and Fireplaces” and NFPA 211.
NOTE: The safe operation of a venting system depends on the proper installation and use of all materials and components supplied by the manufacturer and proper use and operation of the connected heating equipment. Liner and component arrangements depend on the size and configuration of the chimney structure and the type, number and location of the appliances that are to be vented into the chimney.
– Do not connect any appliance that burns a liquid fuel to a chimney liner used to vent a solid fuel burning appliance.
– For solid fuel burning appliances, the cross sectional area of the liner shall not be less than the cross sectional area of the appliance outlet collar. The cross sectional area of the flue shall not be more than three times the cross sectional area of the appliance outlet collar. For solid fuel burning fireplaces, the liner should be at least one-tenth the square inches of the square inches of the fireplace opening. Refer also to N.F.P.A. 211 for solid fuel in the US and CAN/CSA-B365 in Canada. Please note that this formula can vary based on height of the chimney and other determining factors.
– The connector pipe used to connect the appliance to the chimney liner must meet proper clearances to combustibles as determined by the appliance manufacturer’s installation instructions, the national building code, or the local building code, whichever is in force.
– For liner sizing of gas and oil burning appliances please refer to N.F.P.A.54 for gas and N.F.P.A.31 for oil in the US. In Canada refer to the following Installation Codes: CAN/CSA-B139 for oil and CAN/CSA-B149 for gas. Also refer to appliance manufacturer’s instructions. Incorrectly sized liners for these appliances can lead to performance problems and condensation with the lining system.
– The air space clearances between the masonry chimney exterior and combustible materials must be checked to verify that the chimney is in accordance with applicable building code requirements.
– If the chimney is constructed inside the structure, a minimum of two inches of unobstructed air space must surround the chimney to any combustible material. If the chimney is constructed on the outside of the structure, in the US, one inch (1/2” in Canada) of unobstructed air space must be maintained between the chimney and all other
combustible materials. See Table 1 and Figure 2.
– When the chimney passes through a floor, ceiling, or other horizontal or vertical structure, firestops of a non-combustible material must be used.
– IF THE PROPER CLEARANCES LISTED ABOVE CANNOT BE DETERMINED THE LINER MUST BE INSTALLED WITH AN APPROVED INSULATION WRAP.
– This system is approved in Canada and the United States with an approved Ceramic Insulation Wrap to reduce the clearance to combustible construction outside of a masonry chimney only.
The clearance between the masonry chimney and combustible materials is dependent on the installation configuration as shown in Table 1 and Figure 2.
– An approved insulation wrap with 8 lb. density, 1/2” foil faced ceramic fibre blanket will enhance the performance and life of the chimney when:
– The installation needs to meet the requirements of UL1777 at zero clearance to combustibles;
– The chimney being relined is located outside;
– Low flue gas temperatures are anticipated.

TABLE 1 – AIR SPACE CLEARANCES TO LINER (see Fig. 2)

Type of Installation| Stainless Steel Flexible Liner
and interior of Chimney| Clearance Between Chimney Exterior and Combustibles
Clearance ‘A’| Interior Installation ‘IT| Exterior Installation `B’| Country

0″| 2″| 1″| U.S.
Insulated* Stainless Steel Flexible
Liner| 0″| 0″| 0″| Canada
0″| 0″| 0″| U.S.

Insulated Stainless Steel Flexible Liner with an approved Insulation Wrap of 8 lbs. density, 1/2” foil faced ceramic fibre blanket such as our Insulation Wrap Kit – RF101 (*denotes diameter from 5” to 8”).
NOTE: Ensure there is adequate room for both Liner and Wrap.

*Please note: While insulation is not required for every application, it is highly recommended. The performance of the heating system is greatly enhanced when adding an Insulation Wrap. An insulated system helps to improve draft, minimize condensation and flue surfaces warm up quickly. This added feature is important for exterior chimneys.

DETERMINE IF THE CORRECT SIZE LINER WILL FIT INTO THE CHIMNEY

– Since chimneys are usually very sooty and dusty, it is advisable to remove or cover your furniture, rug, etc. for the duration of the cleaning and installation of the liner. The Stainless Steel Flexible Liner can be installed within the existing flue tile or the flue tile can be removed. It is extremely important that the correct size liner will fit into the chimney.
Certain factors, such as chimney construction and offsets in the chimney, may change the size of the interior of the chimney. It is best to prove the interior of the chimney before trying to install the chimney liner. This can be done by lowering a short piece of the intended size liner down the chimney to see if it will pass all the way to the bottom.
You can also use a liner guide cone to accomplish this. If the chimney liner will need to be insulated this will affect the required dimensions needed to install the liner. If the round configurations needed to vent the appliance will not fit the liner may be formed to an oval configuration to fit, however ovalizing the liner will change the cross sectional area.
The size of the liner selected should be the same size of the appliance flue outlet opening or as specified in the appliance manufacturer’s instructions. Correct sizing is critical for venting of low temperature flue products in geographical areas experiencing sustained low ambient temperatures. Improper sizing may lead to excessive con-densation of moisture, creosote build up and poor draft. A certified technician may alter the size of the liner to suit the appliance within codes perimeter. Consult the appliance manufacturer for guidance.
NOTE: Always wear gloves, eye protection and dust respirator.

INSTALLING STAINLESS STEEL FLEXIBLE LINER

– Make sure the thimbles to be used in the installation are in the proper chimney to maintain the required clearance to combustibles for the connector pipe from the appliance. If the clearances are not correct reconstruct the thimble to the proper position.
– Determine the length of the liner by measuring from the bottom of the opening to the top of the chimney. To this measurement add approx. six inches to accommodate the crown and top hardware.
Cut liner to length by using a hacksaw, snips or a disc cutter.

– If necessary, 2 lengths may be joined together by using the flex connector. You can also use the pulling cone to allow an easier installation of leading the liner down from the top of the chimney.
– Remove the snout from the two part tee.
– Attach the tee body to the liner by inserting the liner into the female end tee body as far as possible.
– Using a 5/16” (8mm) nut driver, tighten the worm drive clamp firmly around the liner. If the liner is going to be insulated with a ceramic insulation blanket, install the blanket now. If a tee cap is going to be used, attach it to the body now.
– Take the tee snout that was removed from the tee body and extend the draw band completely, slide the tee snout into the thimble with the draw band centered in the flue. Lower the liner down from the top of the chimney, and feed the tee body through the draw band on the tee snout. You may have to rotate the liner to align the hole in the tee body with the snout. Once you have aligned the tee, tighten the draw band to secure the snout to the tee body.
– Seal the area around the tee snout with mortar for an airtight seal.
– The Top Kit (Top Plate and Liner Cap) is used to bear the total weight of the liner system at the top of the masonry chimney (see Figure 4).

– Your chimney may have a clay-tile liner which protrudes above the chimney. There is no need to remove the top portion of the clay tile liner if it is in good condition. Complete any repairs needed to the chimney crown if any cracks or deterioration is visible.
– If on the other hand the clay tile liner is not in good condition, you will need to make it flush by chipping away at the the excess with a hammer and cold chisel. Make sure pieces of the clay tile liner don’t fall into the flue; remove them if they do. When you have finished making the top of the chimney flush, fill in any cracks and uneven surfaces with mortar. Proceed to install the Top Kit.
– The installation of the Top Kit is accomplished by first removing the Liner Cap portion of the kit by loosening the top worm drive clamp a few turns. Next, install the Top Plate assembly over the liner, tighten the worm drive screw until snug, then attach the Top Plate to the masonry with silicone or tapcons. Cut the liner flush with the top of the assembly and reinstall the Liner Cap portion of the Top Kit.
– To facilitate inspection and cleaning, wall penetrations shall not be placed directly behind the heating appliance.
– A Top Extension is available to extend the height of your flex liner system. The extension attaches to the top plate and the liner cap attaches to the top extension with the securing worm drive clamp.
– Make sure the tee branch is long enough to protrude into the room by at least 2” so a connector pipe can be attached to it.

You can also have the Tee and Tee Cap resting on a solid base support (cement base or stacked brick/rubble). The tee snout is connected to the heating appliance with appropriate connector pipe.
Removal of soot during cleaning is done through the tee branch assembly after the heating appliance has been disconnected (see Figure 5).
NOTE: You will still be required to re-support the flexible liner assembly at the top of the chimney with the above mentioned Top Kit.

FIGURE 6 – Typical Stainless Steel Flexible Liner Installation

INSERT INTO A MASONRY FIREPLACE

– For an insert application into a masonry fireplace, a Insert Liner Kit is available. For this application a tee and tee cap are not required.
This kit comes with a Stove Adapter made to accept our liner into the top female end with our worm drive clamp to tighten it in place. The Stove Adapter slips into the top of the insert collar for an easy transition.
See Figure 7 for a basic installation.
– In certain applications, an elbow would facilitate the connection at the insert. These are available in 30°, 45° or 90°.
– Follow the manufacturer instructions supplied with the insert for more details on how to connect to the appliance.

INSULATING THE LINER (IF REQUIRED)

A note about insulating stainless steel flexible liner: Not all situations require insulation of the chimney liner. The UL1777 Standard for installing stainless steel chimney liners requires insulation because the non-code conforming chimney has zero clearance to combustibles or some other defect. The definition of a code conforming chimney is one that meets or exceeds NFPA 211 for construction of chimneys in the US and CAN/CSA-A405 for Design and Construction of Masonry Chimneys and Fireplaces in Canada.
For the installed liner systems to meet UL standards, all UL listed components used must be installed with proper clearances.
The Insulation Wrap Kit – RF101 (denotes diameter from 5” to 8”) comes complete with the following:
10’ – 1/2” Foiled Insulation Blanket
10’ – Stainless Steel Wire Mesh
10’ – Aluminum Foil Tape
35’ – Stainless Steel Wire

Insulating with Insulation Wrap Kit:
– The liner must be insulated from the bottom of the tee including the tee cap (in the case of an insert application from the stove adapter from where it would stop on insertion into it). The Insulation Wrap must be 3” below the crown of the chimney to allow for vertical thermal expansion.
– After determining this length, prepare sections of the insulation blanket with a minimum of 2” overlap, taped with foil tape.
– Lay down the prepared sections of insulation blanket (foil face down) on a flat surface.
– Lay the liner and the bottom connector (tee branch with tee cap or stove adapter) in the center of the insulation blanket.
– Wrap blanket around the liner. Hold in place every foot with pieces of 8” length of foil tape.
– Once the insulation is in place apply a continuous vertical length of foil tape from top to bottom of the overlapped insulation seam. The insulating wrap must overlap along its length by a minimum of 1”. A wider overlap is allowed but may cause installation difficulties in tight clearance situations.
– Next place insulated liner into the mesh sock.
– Starting at the bottom secure with the stainless steel wire in an helical manner (spiral) all the way to the top and twisted on itself at each end to hold it in place.

The following Figure 8 shows NFPA 211 diagrams for chimney connector systems and clearances to combustible walls (US only). In Canada, refer to CSA-B635 the Installation Code for Solid Fuel Burning Appliances and Equipment.

“Creosote and Soot – formation and need for removal”
Your Stainless Steel Flexible Liner must be installed and serviced by a qualified chimney or venting professional. The need for chimney maintenance depends on the kind of appliance and how it is operated. Gas and oil-burning appliances need very little, but wood-burning appliances may need a great deal of maintenance. Refer also to the appliance manufacturer’s maintenance instructions for recommendations relative to required maintenance of the appliance.
Good operating and firing techniques of your wood burner will have a positive impact in reducing creosote build-up. Burn hot, bright fires and fire each load hot. It is important to load your appliance properly and to avoid smoldering fires. By doing so, it reduces the risk of chimney fires and creosote formation. If your wood is not thoroughly seasoned, split it in smaller pieces instead of larger ones. Ideally, the moisture content of your firewood should be between 18 and 22 percent.
When wood is burned slowly, it produces tar and other organic vapours, which combine with expelled moisture to form creosote.
The creosote vapours condense in the relatively cool liner flue of a slowburning fire.
As a result, creosote accumulates on the flue lining.
When ignited, this creosote creates a chimney fire with extremely high temperatures.
With a new installation, the chimney should be inspected frequently (every two weeks) to determine the rate of creosote formation. When familiar with the appliance and liner characteristics, the liner should be inspected at least once every two months during the heating season to determine if a creosote or soot build-up has occurred.
Check spark arrester screens at least every 2 to 4 weeks. If the spark arrester becomes clogged with creosote, it should be cleaned or replaces.
If creosote or soot build-up has occurred (1/16” or more), it should be removed to reduce the risk of a chimney fire. Every liner and connector pipe shall be inspected annually and cleaned as often as may be necessary to keep the liner and connector pipe free from dangerous accumulation of combustible deposits.
Contact a professional certified chimney sweep for chimney cleaning services and advice if you have any doubts about your ability to clean your liner system or if the task is too large. To visually inspect the chimney, remove the Liner Cap off the liner. Remove the Tee Cap (if so equipped) to clean from the bottom. This will permit the insertion
of a flashlight for inspection. Select the proper sized nylon/poly chimney brush to clean the liner. Make sure the brush passes throughout the complete length of the liner, incuding connectors and tee. It may be required to disassemble the connector assembly from the appliance for complete inspection and cleaning.

If chemical cleaners are used to assist in the cleaning of the Stainless Steel Flexible Liner, make sure it is a product which is non corrosive.
We will assume no liability for damage resulting from the use of chemical cleaners. Chemical cleaners (including sweeping logs products) do not replace the optimal method of cleaning a liner by a mechanical brushing for removal of creosote and other potentially hazardous material. This is in conjunction with a complete evaluation and visual inspection of the system by a professional chimney sweep.
It is important that the Liner system be checked and cleaned annually.
This is for the safety of the homeowner and necessary to meet the warranty requirement.
Avoid burning “green”, “unseasoned” “wet” wood. Heat is wasted as it must first dry and evaporate the moisture content in the firewood.
As the water evaporates it will form into creosote which will then condense in a relatively cool firebox and liner. This will not permit a clean hot burn. Do not burn saltwater driftwood, treated wood, wax logs, pressure treated lumber, rail road ties, or plastics. Fuel other than firewood may burn excessibely hot leading to damages to the liner system and become a serious fire hazard. Burning such materials may also lead to severe corrosion of your appliance and of the liner.
