The chimney should be swept by a suitably qualified chimney sweep who would provide a certificate after sweeping and checking, which should be retained for future reference. A list of HETAS registered sweeps can be found at www.hetas.co.uk<\/p>\n<p>It will be necessary to check that the flaunching at the top of the stack is not cracked, and if so replaced. The brickwork pointing and the flashings should be checked to ensure they are in good order and corrected as necessary. This is required to prevent ingress of rainwater, which, if mixed with carbon deposits on the inside wall of the chimney, could then damage the fabric of the building and the chimney liner.<\/p>\n<p><strong>Use of Flex Tester Kit<\/strong><\/p>\n<p>Prior to installation of the Flex, we recommend that a test length of approx., 1.5m with a nose cone attached to each end, is pulled through the chimney to ensure that the chimney is suitably sized and free from obstructions. Failure to do so may lead to the warranty being invalidated on the Flex if damage has been caused due to snagging on an obstruction.<\/p>\n<p>The tester kit should be pulled down the chimney using a nose cone and string\/rope. A re-usable 1.5m test length complete with two nose cones is available in the TecnoFlex Plus range. Alternatively nose cones can be purchased separately or as part of a Flex Installation kit.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-12451\" src=\"https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/capture.jpg\" alt=\"\" width=\"1485\" height=\"546\" srcset=\"https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/capture.jpg 1485w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/capture-300x110.jpg 300w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/capture-768x282.jpg 768w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/capture-1024x377.jpg 1024w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/capture-960x353.jpg 960w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/capture-736x271.jpg 736w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/capture-777x286.jpg 777w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/capture-720x265.jpg 720w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/capture-1440x529.jpg 1440w\" sizes=\"(max-width: 1485px) 100vw, 1485px\" \/><\/p>\n<p><strong>Ventilation<\/strong><\/p>\n<p>It is very important that sufficient air for combustion is provided to the room containing the appliance, to enable correct and efficient working of the system. Reference should be made to the appliance manufacturer\u2019s instructions and recommendations are also given in the Building Regulations Document J.<\/p>\n<p><strong>Carbon Monoxide Alarms<\/strong><\/p>\n<p>The carbon monoxide alarms should comply with BS EN 50291:2001.<\/p>\n<p>Where a new or replacement fixed solid fuel appliance is installed in a dwelling, a carbon monoxide alarm must be provided in the room where the appliance is located.<\/p>\n<p>Please follow manufacturers instructions with regards to siting and fixing or alternatively :-<\/p>\n<p>a) On the ceiling at least 300mm from any wall or if it is located on a wall, as high up as possible (above any doors and windows), but not within 150mm of the ceiling and<\/p>\n<p>b) between 1m and 3m horizontally from the appliance.<\/p>\n<p>N.B<\/p>\n<p>Provision of a carbon monoxide alarm should not be regarded as a substitute for correct installation and regular servicing.<\/p>\n<p><strong>Delivery to Site and Storage<\/strong><\/p>\n<p>Components should be carefully transported and off loaded.

Where TecnoFlex Plus is to be fitted to the top of an open fire place, a Schiedel Rite-Vent gather unit should be fitted into the throat of the chimney connected to the TecnoFlex Plus and sealed off.<\/p>\n<p>When connecting Triplelock flex to a Schiedel Rite-Vent flue box, the flexible liner simply pushes directly on to the fast fix spigot. No sealant is required.<\/p>\n<p>When making a connection to a fluepipe in another product type, such as rigid stainless steel single or double wall or vitreous enamel, then the appropriate Schiedel approved connector to\/from flexible should be used. The connector should be suitably sealed to the appliance spigot ensuring a gas tight joint.<\/p>\n<p><strong>Connecting Flue Pipe Diameter<\/strong><\/p>\n<p>Connecting Flue Pipe Diameter size should be as recommended by the appliance manufacturer. Under all circumstances the operational requirements of the appliance and the configuration of the flue must satisfy the flue sizing requirements of EN13384-1.<\/p>\n<p><strong>Distance to Combustibles<\/strong><\/p>\n<p>In accordance with building regulations, it is essential that the correct distance to combustible material is maintained on connecting flue pipes. On solid fuel applications, where there is a risk of soot fire, on unmeasured (NM) designated single wall product, this distance is 3 x \u00d8Int of the pipe, e.g. for \u00d8125mm the distance is 375mm and<\/p>\n<p>for \u00d8150mm the distance is 450mm to combustibles on both painted and non painted variants. On measured (M) single wall or double wall products this distance will be as declared by the chimney manufacturer.<\/p>\n<p><strong>Connecting Flue Pipe Route<\/strong><\/p>\n<p>Connecting flue pipes should only be used to connect appliances to a Chimney.They should not pass through any roof space, partition, internal wall or floor, except to pass directly into a chimney through either a wall of the chimney or a floor supporting the chimney.<\/p>\n<p>Connecting flue pipes should be located as to avoid igniting combustible material.<\/p>\n<p>On solid fuel appliances the maximum length of a connecting flue pipe is 2m.This distance is reduced to 1.5m if any of the acceptable alternative methods of connection are adopted as per BS EN15287-1. (See p.6 for full details.)<\/p>\n<p>On appliances with a top outlet, it is recommended that a vertical run of at least 600mm should be allowed immediately above the appliance prior to any change of direction.<\/p>\n<p>On appliances with a rear outlet, it is recommended that there is maximum of 150mm in the horizontal run however under certain conditions, as described in alternative methods in BS EN 15287-1, this may be increased to 450mm.<\/p>\n<p>Within a system (Chimney + Connecting Flue Pipe) there should be no more than 4 changes of direction of maximum 45\u02da. 90\u02da Factory made bends or tees within the system may be treated as being equal to two 45\u02da bends (as per Document J of the Building Regulations issued October 2010).<\/p>\n<p><strong>Inspection<\/strong><\/p>\n<p>On solid fuel applications to conform to Building Regulations, provisions should be made to enable a chimney to be inspected and cleaned.<\/p>\n<p>An inspection pipe, inspection elbow or a 90\u00b0 or 135\u00b0 Tee with tee cap can form a suitable inspection point (unless cleaning\/inspection can be done through the appliance). To aid cleaning, sufficient distance should be left between changes of direction to permit the safe passage of cleaning brushes within the system. This is particularly important\u00a0 on solid fuel applications. It is recommended that chimneys serving solid fuel appliances be swept as frequently as necessary, but at least twice a year.<\/p>\n[\/vc_column_text][vc_column_text]\n<a class=\"mwm-aal-item\" name=\"bs-en-15287-1\"><\/a><h3>BS EN 15287-1<\/h3>\n<p><strong>Acceptable Alternative Methods of Connection<\/strong><\/p>\n<p>Where a horizontal connecting flue of more than 150mm is required to connect a solid fuel fired appliance to a chimney, an installation method as per the examples below may be used provided the following criteria is met:-<\/p>\n<ol>\n<li>The maximum length of horizontal connecting flue pipe does not exceed 450mm;<\/li>\n<li>A Defra exempt appliance or an appliance, which is limited to burning authorised smokeless fuel only, is installed;<\/li>\n<li>A calculation according to BS EN 13384-1 has indicated safe operation of the proposed configuration, and the results of the calculation are left with the householder along with the appliance installation instructions<\/li>\n<li>The appliance manufacturer agrees in writing to the proposed configuration;<\/li>\n<li>The chimney manufacturer agrees in writing to the proposed configuration;<\/li>\n<li>The total length of single wall connecting flue pipe is not more than 1.5m;<\/li>\n<li>The appropriate distances to combustible materials from both the appliance and the connecting flue pipe are maintained.<\/li>\n<\/ol>\n<p>NOTE:<\/p>\n<p>These alternative methods do not apply to Republic of Ireland.<br \/>\n[\/vc_column_text][vc_column_text]\n<a class=\"mwm-aal-item\" name=\"\"><\/a><h3><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-12452\" src=\"https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/1.jpg\" alt=\"\" width=\"1431\" height=\"690\" srcset=\"https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/1.jpg 1431w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/1-300x145.jpg 300w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/1-768x370.jpg 768w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/1-1024x494.jpg 1024w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/1-937x452.jpg 937w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/1-718x346.jpg 718w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/1-759x366.jpg 759w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/1-703x339.jpg 703w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/1-1406x678.jpg 1406w\" sizes=\"(max-width: 1431px) 100vw, 1431px\" \/><\/h3>\n[\/vc_column_text][vc_column_text]\n<a class=\"mwm-aal-item\" name=\"installation-of-the-liner\"><\/a><h3><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-12453\" src=\"https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/2.jpg\" alt=\"\" width=\"1409\" height=\"784\" srcset=\"https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/2.jpg 1409w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/2-300x167.jpg 300w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/2-768x427.jpg 768w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/2-1024x570.jpg 1024w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/2-812x452.jpg 812w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/2-622x346.jpg 622w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/2-658x366.jpg 658w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/2-1316x732.jpg 1316w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/2-609x339.jpg 609w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/2-1218x678.jpg 1218w\" sizes=\"(max-width: 1409px) 100vw, 1409px\" \/>INSTALLATION OF THE LINER<\/h3>\n<p><strong>Handling<\/strong><\/p>\n<p>Suitable PPE (Personal Protection Equipment) must be used when handling stainless steel flexible liners and accessories.

This is provided by installing two 15mm pipes into the masonry at the top of the stack just below the top plate and clamp, at an angle to prevent the ingress of rainwater. lt would also be necessary to install a vent at the base of the stack above the debris plate or the gather unit.This should be an air brick or vent of 20cm (see Fig. 8, 9 ,10 p.10). If the cavity is to be insulated with pearlite, or tube wrap insulation, then two 15mm pipes at the top of the stack to allow any moisture in the insulation to evaporate freely, must still be provided.<\/p>\n<p><strong>Insulation<\/strong><\/p>\n<p>Where the chimney is highly exposed or in a large void, then insulation should be considered. If insulation is required, granules such as Vermiculite, should be poured in around the liner from the top of the stack after fitting a suitable closure plate at the bottom of the system. Alternatively a solid tube of high quality insulation can be used.<\/p>\n<p>Under all circumstances, the chimney stack must be fully weather proofed prior to the installation of the liner and any insulation material. Failure to do so will render the warranty null and void.<\/p>\n<p><strong>Sealing the Flue Liner to the Chimney Pot<\/strong><\/p>\n<p>The plate and clamp holding the liner to the chimney top should be secured to the stack. To weather the top of the chimney stack, seal any gaps between the liner installation and the chimney pot using appropriate acid resistant mortar.<br \/>\n[\/vc_column_text][vc_column_text]\n<a class=\"mwm-aal-item\" name=\"tecnoflex-plus-accessories\"><\/a><h3>TECNOFLEX PLUS ACCESSORIES<\/h3>\n<p><strong>Top of the Chimney<\/strong><\/p>\n<p><strong><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-12456\" src=\"https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig1and2.jpg\" alt=\"\" width=\"1466\" height=\"569\" srcset=\"https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig1and2.jpg 1466w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig1and2-300x116.jpg 300w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig1and2-768x298.jpg 768w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig1and2-1024x397.jpg 1024w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig1and2-960x373.jpg 960w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig1and2-736x286.jpg 736w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig1and2-777x302.jpg 777w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig1and2-720x279.jpg 720w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig1and2-1440x559.jpg 1440w\" sizes=\"(max-width: 1466px) 100vw, 1466px\" \/><\/strong><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-12457\" src=\"https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig3and4.jpg\" alt=\"\" width=\"1469\" height=\"653\" srcset=\"https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig3and4.jpg 1469w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig3and4-300x133.jpg 300w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig3and4-768x341.jpg 768w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig3and4-1024x455.jpg 1024w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig3and4-960x427.jpg 960w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig3and4-736x327.jpg 736w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig3and4-777x345.jpg 777w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig3and4-720x320.jpg 720w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig3and4-1440x640.jpg 1440w\" sizes=\"(max-width: 1469px) 100vw, 1469px\" \/><\/p>\n<p><strong><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-12458\" src=\"https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig5and6.jpg\" alt=\"\" width=\"1386\" height=\"576\" srcset=\"https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig5and6.jpg 1386w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig5and6-300x125.jpg 300w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig5and6-768x319.jpg 768w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig5and6-1024x426.jpg 1024w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig5and6-960x399.jpg 960w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig5and6-736x306.jpg 736w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig5and6-777x323.jpg 777w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/fig5and6-720x299.jpg 720w\" sizes=\"(max-width: 1386px) 100vw, 1386px\" \/>Combined Pot Hanger &amp;

However, connection to an appliance that is connected to the fuel supply must be carried out by a GAS SAFE (for gas) or OFTEC (for oil) registered installer.We recommend the use of HETAS approved installers for solid fuel applications. If a non HETAS approved installer is used, then the installation must be signed off by a Building Control Inspector prior to being used.<\/p>\n<p><strong>Are there any special tools or equipment required?<\/strong><\/p>\n<p>No.The following would be necessary:- suitable cutting equipment, screwdriver, and adjustable spanner.To weather the top of the chimney stack and seal, a trowel with some sand and cement will be required. A closure plate would need to be fitted at the bottom of the system using appropriate fixings.<\/p>\n<p><strong>Can Flue Liner be installed anywhere?<\/strong><\/p>\n<p>No. Flue liner must only be installed inside a masonry brick chimney, as defined in the table on page 2 depending on the type and year of chimney construction.<\/p>\n<p><strong>Are any other materials required?<\/strong><\/p>\n<p>The connection to the appliance should be made using a high temperature sealant and\/or glass rope to ensure a positive seal. Where TecnoFlex Plus is to be fitted to the top of an open fire place, a Schiedel Chimney Systems gather unit should be fitted into the throat of the chimney connected to the TecnoFlex Plus and sealed off.<\/p>\n<p><strong>The chimney has been previously used for an open solid fuel fire, can a flue liner be installed straight away?<\/strong><\/p>\n<p>No, in all cases, the chimney must be inspected for deterioration and if necessary, any remedial work required must be carried out. The chimney should be swept, preferably by a member of NACS (National Association of Chimney Sweeps) or a suitably qualified chimney sweep who would provide a certificate after sweeping and checking, which should be retained for future reference. A list of HETAS registered chimney sweeps can be found at www.hetas.co.uk<\/p>\n<p><strong>How is the liner supported?<\/strong><\/p>\n<p>Triplelock Flex is relatively light so it can be supported at the top of the chimney by using a clamp plate, which should be fixed to the top of the masonry stack.<\/p>\n<p>TecnoFlex Plus however, is heavier and would be supported either by using a separate plate and clamp, which would be securely fixed to the top of the stack, or using a suitable pot hanger &#8211; see p.5 for more details.Where a tee is used at the base of the system to provide a drain point\/cleaning access or connection to a flue pipe from the appliance, a bottom support bracket would be required, fixed to the inside of the stack.<\/p>\n<p><strong>How is the liner cut to the correct length for the chimney?<\/strong><\/p>\n<p>After the length of flue liner has been connected to the appliance, fluebox spigot or to the flue pipe connecting to the appliance, allow sufficient liner to protrude at the top of the chimney stack in the case of the pot hanger terminals, or above the top plate and clamp to ensure a positive location within the relevant terminal, and cut.This should be done by using an industrial knife or metal snips. At all times extreme care must be taken when cutting the liner and strong industrial gloves plus long sleeved overalls should be worn as cut edges are very sharp. In addition, any tape secured to the ends of the liner, which is provided for safe handling prior to installation, must be removed before completion, and commissioning of the full system.<\/p>\n<p><strong>Is there a correct \u2018way up\u2019 to install the flue liner?<\/strong><\/p>\n<p>Yes, on TecnoFlex Plus multifuel Iiner; the directional arrow on the outside of the liner indicates the direction of flue gases, and this must be pointing upwards towards termination.<\/p>\n<p>Triplelock Flex can be installed either way up.<\/p>\n<p><strong>How should the Terminal be connected to the flue liner and how is the installation made weatherproof?<\/strong><\/p>\n<p>For gas and oil systems, the terminal should be fitted over the protruding end of the liner, ensuring that the flex does not protrude beyond the stop bead in the terminal, and riveted or secured using self tapping screws. On TecnoFlex Plus, where used on solid fuel appliances, either a proprietary chimney pot must be fitted by bedding the pot on to the top plate or, whilst technically an open terminal provides the least possible resistance to the flue gases, in order to prevent excessive rain ingress, a raincap or combined pot hanger and terminal may be used. Only 316L material is used on Schiedel\u2019s terminals including raincaps, pot hangers and combined pot hanger and terminal to provide the highest corrosion resistance. In all cases, the top of the stack should then be weathered and sealed using a suitable acid resistant mortar to prevent ingress of water.<\/p>\n<p><strong>Are there any special requirements for providing combustion ventilation?<\/strong><\/p>\n<p>It is very important that sufficient air for combustion is provided to the room containing the appliance, to enable correct and efficient working of the system.

The liner must be sized to meet the requirements of the new appliance, please refer to the flue size selection guide and the appliance manufacturer\u2019s instructions. A lined chimney is defined as one which is fitted with a clay or concrete liner within the flueway, complying with Document J.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-12524\" src=\"https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/chimney-need-relining.jpg\" alt=\"\" width=\"1457\" height=\"324\" srcset=\"https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/chimney-need-relining.jpg 1457w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/chimney-need-relining-300x67.jpg 300w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/chimney-need-relining-768x171.jpg 768w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/chimney-need-relining-1024x228.jpg 1024w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/chimney-need-relining-960x213.jpg 960w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/chimney-need-relining-736x164.jpg 736w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/chimney-need-relining-777x173.jpg 777w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/chimney-need-relining-720x160.jpg 720w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/chimney-need-relining-1440x320.jpg 1440w\" sizes=\"(max-width: 1457px) 100vw, 1457px\" \/><strong>What basic components are required for a typical relining system?<\/strong><\/p>\n<p>A typical installation would include the liner, a clamp plate and terminal. These are generally supplied in a kit form for Triplelock Flex, a debris plate would also be required to seal off the base of the stack. In the case of an open fire using TecnoFlex Plus, a gather unit, and debris plate would be necessary together with a top insert and a suitable terminal\/ pot. When installing a flue liner for use on a gas fire complying to BS7977-1, BS7977-2 and BS EN 509 (i.e. Radiant, BBU, DGF or ILFE), a range of flueboxes are available with Triplelock Flex and TecnoFlex Plus spigots for use within the chimney opening.<\/p>\n<p><strong>When a roof has been converted from flat to pitched, and the existing chimney is capped, can the chimney be reused to accommodate a new appliance?<\/strong><\/p>\n<p>The chimney can be reused providing the existing brickwork is inspected to ensure it is in good condition.The chimney can be lined with the appropriate liner, ensuring that the liner is used only inside the stack. Extension from the top of the capped off stack should be made using a System Chimney approved to BS EN1856-1, such as Eco ICID or ICS. Connection from the appliance should be made using a connecting flue pipe approved to EN1856-2 such as Prima Plus for all fuels, or Prima Smooth in the case of solid fuel<\/p>\n<p><strong>Is the flexible liner pulled up or down the chimney, and what should be used?<\/strong><\/p>\n<p>The flue liner can be pulled up or down the chimney the chimney using a nose cone and string\/rope. A nose cone can be purchased, rope attached, and connected to the end of the liner. The existing chimney has a flexible flue liner fitted, connected to an old gas fire.<\/p>\n<p><strong>If the fire was to be changed can the liner be reused for the new fire?<\/strong><\/p>\n<p>Yes, in general terms, providing the diameter and type of flex is suitable for the new appliance to be fitted, the installer has inspected the liner and is satisfied that the condition of the liner is such that it may be reused with the new appliance. However, as the lifespan of the previous appliance and liner may not be known, it is strongly recommended the old flueliner is removed, the chimney swept, then a suitable new liner installed.<\/p>\n<p><strong>Are there any other maintenance checks that should be carried out when installing a new appliance?<\/strong><\/p>\n<p>It will be necessary to check that the flaunching at the top of the stack is not cracked, and if so replaced.The brickwork pointing and the flashings should be checked to ensure they are weather tight and repaired where necessary.<\/p>\n<p><strong>Can flue liner be used on condensing appliances?<\/strong><\/p>\n<p>We recommend the use of TecnoFlex Plus on condensing Gas and Oil appliances. The smooth inner liner allows for the swift drain down of condensates to a suitable drain point at the base of the vertical system.TecnoFlex Plus can be used on appliances with a maximum pressure of 200Pa.The liner should be used in combination with connecting flue pipe and fittings, which have been tested and approved to BS EN1856-2. An acid resistant sealant, such as Rotempo or equivalent should be used to seal the joint between the flexible liner and the screw fit adaptor.<\/p>\n<p><strong>The chimney to be lined is very tall, can lengths of flue liner be joined?<\/strong><\/p>\n<p>It is recommended that flexible flue liners be installed in continuous lengths without joiners. Schiedel Chimney Systems can supply all flue liners in specific lengths on drums or in pack form upon request. On TecnoFlex Plus installations, joiners are only permitted where the chimney liner length exceeds the maximum length available and details of the installation are agreed in advance, in writing, in compliance with product warranty conditions.<\/p>\n<p><strong>Multi-Fuel Applications<\/strong><\/p>\n<p>Multi-Fuel refers to an appliance which may be used to burn either seasoned wood, with a maximum moisture content of 20%, or approved solid fuels.These fuels must not be mixed, as this increases the risk of deposits being built up in the liner.<\/p>\n<p><strong>Do I require an appliance connector to fit the flex to the appliance spigot?<\/strong><\/p>\n<p>In the event of connecting directly to the appliance i.e a gas fire with back boiler within the chimney stack, it will generally be unnecessary to use an appliance connector. When making a connection to a connecting flue pipe in another product type, then the appropriate connector to\/from flexible would be used. In all cases, a gas tight joint must be ensured.<\/p>\n<p><strong>Will the flue liner be OK to use after a chimney fire?<\/strong><\/p>\n<p>The flue liner could be damaged under the conditions of a chimney fire, and must always be inspected by a suitably qualified individual (e.g. HETAS registered installer and replaced as necessary), before using the appliance or fire again.<br \/>\n[\/vc_column_text][vc_column_text]\n<a class=\"mwm-aal-item\" name=\"after-installation\"><\/a><h3>AFTER INSTALLATION<\/h3>\n<p><strong>Testing and Commissioning prior to first use<\/strong><\/p>\n<p>This is carried out using a flue flow test as described in BS EN 15287 Parts 1 &amp; 2, with reference to the appropriate appliance type.<\/p>\n<p><strong>Appliance Operation<\/strong><\/p>\n<p>If the appliance is slumbered overnight or for longer periods then it is advisable to run the appliance at controlled high fire condition for a period of at least 30 minutes. Prolonged slumbering of the appliance is a contributing factor to a liner failure. It is important to maintain sufficiently high flue gas temperatures in order to avoid condensate and acid corrosion problems, and to ensure complete combustion of the fuel.<\/p>\n<p><strong>Maintenance<\/strong><\/p>\n<p>Each chimney must be designed to allow for easy inspection; sweeping should be carried out by competent persons. On solid fuel applications a list of HETAS registered sweeps can be found at www.hetas.co.uk.<\/p>\n<p>Chimney flue cleaning and inspection require the use of appropriate tooling \u2013 under no circumstances should chemical cleaners or mild steel tools be used to sweep stainless steel chimneys. Cleaning\/inspection of any chimney system should be carried out at least once a year, along with maintenance of the appliance, but it is recommended that chimneys serving solid fuel appliances be swept at least twice a year, at the end of the heating season to remove any deposits, which may have built up during the season, and prior to the start of the next heating season to ensure that the the flue way is clear of any blockages such as birds nests etc.<\/p>\n<p>We would advise that monthly checks are carried out to ensure that there is no build up of any deposits in the flue way between appliance and system chimney or chimney liner.<\/p>\n<p><strong>Fuel Storage and Usage<\/strong><\/p>\n<p>Where solid fuels are being used, correct storage is critical and fuels must be kept dry. Wood must be seasoned prior to use, with a maximum moisture content of 20%. Only approved fuels should be used. Refer to HETAS list for details on.The fuel used must be suitable for the appliance &#8211; please refer to manufacturer\u2019s instructions.<br \/>\n[\/vc_column_text][vc_column_text]\n<a class=\"mwm-aal-item\" name=\"notice-plate\"><\/a><h3>NOTICE PLATE<\/h3>\n<p><strong><img loading=\"lazy\" decoding=\"async\" class=\"alignright wp-image-12523\" src=\"https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/notice-plate.jpg\" alt=\"\" width=\"367\" height=\"270\" srcset=\"https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/notice-plate.jpg 679w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/notice-plate-300x220.jpg 300w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/notice-plate-615x452.jpg 615w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/notice-plate-471x346.jpg 471w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/notice-plate-498x366.jpg 498w, https:\/\/www.schiedel.com\/uk\/wp-content\/uploads\/sites\/12\/2018\/09\/notice-plate-461x339.jpg 461w\" sizes=\"(max-width: 367px) 100vw, 367px\" \/>Notice Plate for Flexible Liner Product<\/strong><\/p>\n<p>The Notice plate should be marked up in indelible ink and securely fixed in an unobtrusive but obvious position within the building such as:<\/p>\n<ul>\n<li>Next to the electricity consumer unit.<\/li>\n<li>Next to the chimney installation described.<\/li>\n<li>Next to the water supply stop-cock.<\/li>\n<\/ul>\n[\/vc_column_text][vc_column_text]\n<a class=\"mwm-aal-item\" name=\"product-guarantee\"><\/a><h3>PRODUCT GUARANTEE<\/h3>\n<p><strong>What is the life expectancy and are there any guarantees on the liners?<\/strong><\/p>\n<p>We are confident in our products and so offer you (the owner) a generous guarantee in relation to the flexible liner system (the System).
