Before a flue system is installed always employ a qualified & insured fitter/chimney sweep/gas fitter/engineer to certify that the building is compliant with building regulations and fit for purpose. 32. Under no circumstances should open fire fuel be burnt in a closed appliance this will damage the flue and void any warranty. 4
CARE AND MAINTENANCE Introduction Many solid fuel fired appliances are expected to "work" 24 hours a day, 365 days a year, keeping us warm and supplied with constant hot water. However, like any other machines, they work better and last longer when correctly installed, burn the right fuel and are properly maintained. It is therefore important to ensure that new installations are carried out by recognised and established heating engineers and serviced by competent companies working in this area. Keep warm and safe by taking the simple steps below. Fuel For the best value for money it is important to burn the right fuel of the correct size for your appliance. Never store your fuel too close to the appliance. Always check with your coal supplier that the coal used is suitable for closed appliances. Air supply All fuels require an adequate supply of air to make them burn correctly. If too little air is available, fumes that are harmful to your family may escape into the room. If you have double glazing or draught proofing you will need to allow air to enter the room in which the appliance is installed via an air brick or grille. Never seal air bricks or grills up, you may be putting your family at risk. Seek advice if you are in any doubt. Flue cleaning Many solid fuel fired appliances have flueways through which the hot gases pass to the chimney. These flueways should be swept clean every month to remove any soot or ash. Some stoves and roomheaters have a removable/drop down plate in the top of the fire box - this should also be removed and cleaned once a month. Remember, always let the fire go out the day before cleaning. Chimney sweeping All chimneys must be swept at least once a year by an approved sweep. However, if your appliance is used continuously throughout the year or burns wood and coal more frequent sweeping is recommended. The best time to have your chimney swept is at the start of the heating season. It is also strongly recommended that the chimney be swept after any prolonged period when the appliance has not been used, eg holidays, etc. Remember these recommendations apply even if you burn smokeless fuels. Ash removal If ash is allowed to build up within the appliance the fire will not burn properly and the appliance may be damaged. Generally speaking, the appliance should be de-ashed before being filled with new fuel. The ashpan should be gently removed from the ash pit area and emptied into a suitable container. A hot ash carrier (a metal box with a lid) is ideal for this purpose. The ash pan should be replaced, the fire bed de-ashed with a poker or the de-ashing mechanism on the appliance and fresh fuel added. Fireguards A fireguard must be used to protect children under the age of 12 from touching any heating appliance. Remember to always use a spark guard with any open fire. Carbon monoxide detector It is recommended that a carbon monoxide detector be placed in every room with a heat producing appliance or flue system. 5
SWR/SF (PRH) 316L –Single wall flue range Introduction The SWR/SF (Multi fuel) range is a factory made cylindrical flue, designed to limit pressure drop. A diameter range from 125mm to 250mm provides better performance depending on the type of fuel, heat generated and the flue height. Available in modular units of 1000mm and 670mm and 330mm in length and all the accessories needed for a good connection (tees, elbows, hats, etc). The dual-socket and locking band assembly is quick and secure. Product Designation: EN1856-1. T450-N1-D-Vm-L50080-G400-400 EN1856-1. T300 N1-W-Vm-L50080-O40-40 EN1856-1. T250 H2-W-Vm-L50080-O40
Description SWR/SF flues are made from 316L stainless steel. They are designed for a rapid temperature rise and the high quality alloy steel offers better corrosion resistance. SWR/SF flues are welded with a continuous seam for better sealing. Note: The corrosion resistance of stainless steels is not due to the thickness of the material but the quality of the alloy composition. Use Internal & external -Multi-fuel heat producing appliances. -Connecting element or system for fireplaces, inserts & wood burners. -Ventilation flue for heating, cooking, laboratories. Hot or cold air. Maintenance Cleaned by chimney sweeping brush. -Multi-fuel: 1 time per year minimum -Wood: 2 times per year or per heating season -Coal: 2 times per year or per heating season. Check for leakage after each cleaning. Steps should be taken to insure cleaning access is provided and that the joints are accessible for inspection. Fuels -Gas -Gas condensing -Oil -Wood -Coal (Always check with your supplier that the coal you burn is suitable for closed appliances) 6
Installation of SWR/SF flues Precautions -The diameter must be determined by the appliance manufacturer, fuel used and the height of the flue. -Installer must conduct an audit of the chimney to ensure free passage. -Masonry chimney should be clean and dry. Cleaned by a chimney sweep. -Provide adequate ventilation. -Always refer to local building regulations when planning any installation. Installation Installation in a masonry chimney: Items must be lowered through the chimney with the spigot down. In the case of a multi storey, it is necessary to use a winch. Attach a centring collar with tabs every 4 meters. Install a base support/ bracket at the bottom. Make sure to allow 20cm² of ventilation into the masonry chimney. Attach a flashing and storm collar at the top of the masonry ensuring the free expansion of the flue. The storm collar should be installed 12mm above the flashing to allow free ventilation improving the performance of the flue system; Note: In an installation where the flue and size permits, the performance of the flue can be substantially improved by using rock wool insulation between the flue & masonry. The flue system can then be connected directly to an appliance using a wide selection of Tees and bends. Self-supported For interior applications, this single wall pipe is reserved solely for the extraction of fuel gas. In all cases, it is necessary to meet regulatory requirements for clearances to combustibles and it is necessary to clad the flue in the living areas with a non-combustible material. Similarly, outside the foot of the pipe must be protected from contact to a height of 2 meters. Note: The SWR/SF flue is not insulated. Its use as an external flue can generate excessive condensation and disrupt the draw in cold outside temperatures. We advise the use of the TWR insulated flues which are better suited to such applications. Direction -A vertical installation of with slope of ±3° (corresponding to ±5cm per meter) is preferred for the condensate to travel freely down the flue system. -Adjustments in length are using the adjustable element. This item may be cut to length (minimum 100 mm slipcase). Cutting standard elements is prohibited. -The seal will be made with a silicon paste or ceramic (1100°C), compressed by the locking band. -Accessories such as tees and inspection doors allow the installation of flue gas analysis devices, temperature or draw controls. -The maximum diagonal flue length must match 20% of the total height, not to exceed a total length of 7 meters or comply with the appliance manufacturer instructions and the local building regulations. 7
Support - Staying SWR/SF flues are not self-supporting. They must be supported in all installations along a wall, or on a specially built mast. A support is needed as soon as the flue system exceeds the last attachment point by more than 2 elements. It is preferred that a rigid rigging is used, wire rope will be used as a last resort with the necessary precautions. A support bracket must be placed at the foot of flue system, and then every 20 meter for flues up to 250mm in diameter. Wall bands are required every 3 meters. It is advised to position the supports just below the collar joining (female side of the elements). Exit and sealing roof Two pitched roof flashings are available: one for slopes of 5° to 30°, the other for slopes of 31° to 45°.They are made of aluminium to facilitate cutting and adjustment. Special parts can be manufactured for specific sites. Flat roof flashings are also available for sealing flat roofs and the tops of masonry chimneys. All flashings require a storm collar.

Installation Installation on a pellet stove: Many wood pellet burning appliances come from parts of the world where this type of equipment is popular and there is a long standing tradition of wood burning and a strictly regulated chimney sweeps and engineers. Installations must comply with local building regulations despite manufacturers instructions to the contrary. This issue relates particularly to chimney in terms of size, design and point of discharge. Often these appliances are highly efficient and controllable providing differing flue gas temperature and condensation risks. As a result, the fitting of these appliances into a cold or large flue must be avoided. It is highly recommended that you consult a specialist pellet fitter prior to installation of a pellet stove. Note: The PN vitreous enamel flues are not insulated. Its use as an external flue is prohibited. We advise the use of the TWR insulated flues which are better suited to such applications. When working this flue is extremely hot a fire guard should be provided. Direction A vertical installation of with slope of ±3° (corresponding to ±5cm per meter) is preferred for the condensate to travel freely down the flue system.

T600-N1-W-V2-L50060-G50 Applications: -For internal and external installations. -For connection to Domestic Heat producing appliances. Insulation: The 27/28 mm of rock wool insulation has several advantages: it reduces heat loss when the fumes are relatively cold, it helps maintain a consistent draw and ensures a good draft. It also limits the temperature of the outer wall of the flue in the cases of hot gases or soot fires. Assembly: The assembly and sealing is provided by the male/female stainless steel collar in conjunction with a quick clip locking band, included with each item. This unique system makes on-site assembly of the various elements very easy. Corrosion resistance (inner wall): The inner wall which comes in contact with smoke, is made of high alloy stainless steel, selected for its resistance to corrosion. Heating up: The inner wall is thin stainless steel, allowing a very rapid warming, and promoting a good draw. Diameters and dimensions: TWR flues have a circular section with a very smooth inner wall, which gives them a low coefficient of loss. Given the range of diameters available, it is possible to calculate the optimum flue arrangement according to the heater, height, fuel and environment.

Installation General. -Installations must comply with local building regulations. -The assembly direction, as shown on the elements must be respected (core socket up). -In all cases, it is necessary to comply with regulatory clearance to combustibles -Flues must be enclosed in inhabited areas, with a non-combustible material. The distance between the cladding and the pipe is 80 millimetres. Determining diameter. The diameter of the flue pipe must be determined by the appliance manufacturer, power output, fuel used, pressure loss and the flue height.
14
Minimum height. -The flues have a minimum height of 5 meters. -For roof slopes greater than 10° flues must go above the roof ridge by 100cm, for flat roofs or with a pitch less than 10° the flues must go 1.2 meters above. Or as specified in local building regulations -An overall slope of ±3° should be maintained to allow evacuation of condensate. -Maximum diagonal length must not exceed 20% of the total height of the flue and not exceeding a total of 4 meters. Or as specified in local building regulations. Supports-Collars-Ties TWR flues are not self-supporting they must be anchored to a wall. Where no wall is present and where the flue system extends beyond the last anchor point by more than 1.5m, a structural support is required. -Steel cables are to be used only as a last resort, and with the necessary precautions. -A base bracket must be placed at the foot of the flue system and thereafter every 10 meters. -Offsets of more than 1 meter in length, without the possibility of wall bands, must also be supported, to avoid a cantilever, using a specially manufactured base bracket. -The wall bands will be set every 2meters. -The maximum angle allowed in these flues is 45° for solid fuel. Crossing the floor/ceiling. -When passing through a building, it is necessary to meet regulatory clearance to combustibles. -When passing through floors and ceilings a fire-gap allows ventilation of the flue. For tall buildings, this ventilation will be accomplished through grills at the top and bottom of the flue casing. -The sealing of TWR flues in plaster or concrete is to be avoided, to freely allow expansion. -The exterior skin of the flue in all living areas should be clad with a non-combustible material. -Similarly, outside the flue must be protected from human contact up to a height of 2 meters. -Any joint between of two pipe elements should not be placed in void of a floor wall or ceiling. Exit and roof waterproofing. We offer aluminium flashing for roofs with or without a slope. The flashings are made of aluminium to easily facilitate cutting and alteration. For tiled roofs, we offer flashing kits with a lead bib. Special parts can be manufactured to specification. A storm collar is required with each flashing.
15
Fire stops -TWR flues must be accompanied by an approved fire stop where they pass through ceilings or between inhabited areas. -The fire stop must include the required 80mm of ventilation around the flue during normal use. -TWR flues must extend a minimum of 150mm down from the underside of the fire stop. -Where the flue system passes through an inhabited area the flue must be clad in a non-combustible material with an air gap of 80mm minimum (do not fill with rock wool). -In an attic area the flue should be clad in a non-combustible material or wire mesh to ensure an air gap of 80mm. -Steps should be taken to ensure that no combustible materials can be placed closer than 80mm to the flue system post installation. -Always refer to the local building regulations. Warning: Twin wall flues get very hot provision should be made to insure that they are protected from human contact. It is recommended that a warning be clearly placed every 3m to highlight the danger.

Installation General. -Installations must comply with local building regulations. -The assembly direction, as shown on the elements must be respected (male up). -In all cases, it is necessary to comply with regulatory clearance to combustibles -Flues must be enclosed in inhabited areas, with a non-combustible material. The distance between the cladding and the pipe is 80 millimetres. Determining diameter. The diameter of the flue pipe must be determined by the appliance manufacturer, power output, fuel used, pressure loss and the flue height.

Minimum height. -The flues have a minimum height of 5 meters. -For roof slopes greater than 10° flues must go above the roof ridge by 100cm, for flat roofs or with a pitch less than 20° the flues must go 1.2 meters above. Or as specified in local building regulations -An overall slope of ±3° should be maintained to allow evacuation of condensate. -Maximum diagonal length must not exceed 20% of the total height of the flue and not exceeding a total of 7 meters. Or as specified in local building regulations. Supports-Collars-Ties TWR flues are not self-supporting they must be anchored to a wall. Where no wall is present and where the flue system extends beyond the last anchor point by more than 1.5m, a structural support is required. -Steel cables are to be used only as a last resort, and with the necessary precautions. -A base bracket must be placed at the foot of the flue system and thereafter every 10 meters. -Offsets of more than 1 meter in length, without the possibility of wall bands, must also be supported, to avoid a cantilever, using a specially manufactured base bracket. -The wall bands will be set every 2.50 meters, the vertical parts in outdoor use, every 3 meters in internal segments and all diagonal sections. The maximum angle allowed in these flues is 45°. -The adjustable flue is not lad bearing, it is necessary to reinforce it by external means. Crossing the floor/ceiling. -When passing through a building, it is necessary to meet regulatory clearance to combustibles. -When passing through floors and ceilings a fire-gap allows ventilation of the flue. For tall buildings, this ventilation will be accomplished through grills at the top and bottom of the flue casing. -The sealing of twin wall flues in plaster or concrete is to be avoided, to freely allow expansion. -The exterior skin of the flue in all living areas should be clad with a non-combustible material. -Similarly, outside the flue must be protected from human contact up to a height of 2 meters. -Any joint between of two pipe elements should not be placed in void of a floor wall or ceiling. Exit and roof waterproofing. We offer aluminium flashing for roofs with or without a slope. The flashings are made of aluminium to easily facilitate cutting and alteration. For tiled roofs, we offer flashing kits with a lead bib. Special parts can be manufactured to specification. A storm collar is required with each flashing.
20
Fire stops -Twin walled flues must be accompanied by an approved fire stop where they pass through ceilings or between inhabited areas. -The fire stop must include the required ventilation around the flue during normal use. -The Twin walled flues must extend a minimum of 150mm down from the underside of the fire stop. -Where the flue system passes through an inhabited area the flue must be clad in a non-combustible material with an air gap of 80mm minimum (do not fill with rock wool). -In an attic area the flue should be clad in a non-combustible material or wire mesh to ensure an air gap of 80mm. -Steps should be taken to ensure that no combustible materials can be placed closer than 80mm to the flue system post installation. Warning: Twin wall flues get very hot provision should be made to insure that they are protected from human contact. It is recommended that a warning be clearly placed every 3m to highlight the danger.
