WESTFIRE UNIQ 15, 16, 20 WOODSTOVE UNIQ 15, 16, 20 dimensions STOVE PERFORMANCE & TESTING Westfire UNIQ 15, 16 & 20 have been approved in accordance with EN 13240. Westfire UNIQ 15, 16 & 20 are DEFRA approved models for burning wood in a smoke control area. PREPARATORY WORK AND SAFETY CHECKS IMPORTANT WARNING This stove must not be installed into a chimney thatt serves any other heating appliance. There must not be an extractor fan fitted in the same room as the stove as this can cause the stove to emit fumes into the room. ro CHIMNEY Chimney Connection Flue Diameter 150mm (175cm2) IMPORTANT: When installing the UNIQ 15, 16 & 20 wood stoves remove steel retaining bar across flue exit. Remove bolts and take out bar replace and bolt cast onto collar. In order for the stove to perform satisfactorily the chimney height must be sufficient to ensure an adequate draught draught so as to clear the products of combustion and prevent smoke problems into the room. Minimum draft: UNIQ 15, 16, 20 stove has been tested with a draft of 12 Pa. Maximum draft 25 Pa. Flue gas flow 4.2 g/sec. Flue gas temperature 240°C. approximately 12 Pa. NOTE: A chimney height of not less than 4.5 metres measured vertically from the outlet of the stove to the top of the chimney should be satisfactory. Alternatively the calculation procedure given in BS 5854:1980 may be used as the basis for deciding whether a particular chimney design will provide sufficient draught. The outlet from the chimney should be above the roof of the building in accordance with the provisions of Building Regulation Regulations Approved Document J. If installation is into an existing chimney himney then it must be sound and have no cracks or other faults which might allow fumes into the house. Older properties, especially, may have chimney faults or the cross section may be too large i.e. more than 160 mm x 160 mm. Remedial action should sho be taken, if required, seeking expert advice, if necessary. If it is found necessary to line the chimney then a flue liner suitable for solid fuel m must ust be used in accordance with Building Regulations Approved Document J. Any existing chimney must be clear of obstruction bstruction and have been swept clean immediately before installation of the stove. If the stove is fitted in place of an open fire then the chimney should be swept one month after installation to clear any soot falls which may have occurred due to the difference in combustion between the stove and the open fire. If there is no existing chimney then either a prefabricated block chimney in accordance with Building Regulations Approved Document J or a twin walled insulated stainless steel flue to BS 4543 can be used. These chimneys must be fitted in accordance with the manufacturer’s instructions and Building Regulations. A single wall metal fluepipe is suitable for connecting the stove to the chimney but is not suitable for using for the complete complete chimney. chimne The chimney and connecting fluepipe must have a minimum diameter of 150 mm and its dimension should be not less than the size of the outlet ssocket of the stove. Any bend in the chimney or connecting fluepipe should not exceed 45°. 90° bends should not be used. If it is found that there is excessive draught in the chimney then either an adjustable flue damper or alternatively a draugh draught stabiliser should be fitted. The adjustable flue damper should not close off the flue entirely but should in its closed position leave a minimum continuous opening op free area of at least 20 % of the total cross sectional area of the flue or fluepipe. Adequate provision e.g. easily accessible ccessible soot door or doors must be provided for sweeping the chimney and connecting flue pipe Distance to Combustible materials Combustible materials should not be located where the heat dissipating through the walls of fireplaces or flues could ignite it. Therefore when installing the stove in the presence of combustible materials due account must be taken of the guidance on the separation of combustible material given in Building Regulations Approved Document J and also in these stove instructions. Hearth The hearth should be able to accommodate the weight of the stove and its chimney if the chimney is not independently supporte supported. The Westfire UNIQ 15, 16, 20 wood stove has been tested and is suitable to be installed on a 12mm non combustible plate such as Westfire 12mm glass plates or 20mm slate plates. Installation of all hearths should comply in size and construction so that it is in accordance with the provisions of the current Building Regulations Approved Document J. The clearance distances to o combustible material beneath, surrounding or upon the hearth and walls adjacent to the hearth should comply with the guidance guidan on the separation of combustible material given in Building Regulations Approved Document J and also in these stove instructions. instructions If the stove is to be installed on a wooden floor, it must be covered with a non non-combustible combustible material at least 12mm thick, in accordance with Building Regulations Approved Document J, to a distance of 30 cm in front of the stove and 15 cm to each side m measuring easuring from the door of the combustion chamber. Combustion air supply In order for the stove to perform efficiently and safely there should be an adequate air supply into the room in which the st stove is installed to provide combustion air. This is particularly ularly necessary if the room is double-glazed double glazed or a flue draught stabiliser is operating in the same room as the appliance. The provision of air supply to the stove must be in accordance with current Building Regulations Approved Document J. An opening wind window ow is not appropriate for this purpose. Air inlets must be positioned in such a way that they cannot be blocked. An air inlet may be a vent (the vent must be open and the th capacity of the vent sufficient when the stove is lit) or a fresh air system linked to o the stove. The UNIQ 15, 16 & 20 are available with a closed air supply collar (additional item) this enables the stove to take combustio combustion air directly from outside with a 100 mm pipe from the stove. There are no European rules regarding the minimum distance to non-flammable non flammable walls, Westfire recommend leaving a gap of at least 10 cm behind and to sides of stove. Soapstone base and top Plates for the UNIQ 16/20 When installing a UNIQ 16 or 20 with Soapstone tone top plates remove standard louvre grill top plate from stove. Place soapstone panels directly on top of stove and fit new rear grill to rear. If top flue exit is not used a cover plate is supplied on the stove to cover flue area. When installing a Uniq 16 or 20 with a base soapstone a 12mm floor plate or construction hearth is still to be installed in accordance with doc document J regulations. Westfire Insulated chambers The Westfire UNIQ 15, 16, 20 wood burning stove is lined with heat deflection panels and baffles, these panels are designed to ensure the maximum efficiency and are an integral part of the clean burn process of the stove. These baffles should not be removed apart from for cleaning the stove. Any defective panels should be replaced. Connection to chimney Westfire UNIQ 15, 16, 20 wood stove has both rear and top flue connector that allows connection to either a masonry chimney o or a prefabricated factory made insulated metal chimney in accordance with the instructions for “Connection to t chimney” given in the instruction booklet. Commissioning and handover Ensure loose parts are fitted in accordance with the instructions, page 15 & 16. ‘ Vermiculite fire brick installation sequence’ sequence’ before handover. Operation of primary and secondary airr controls must be fully explained. On completion of the installation allow a suitable period of time for any fire cement and mortar to dry out, when a small fire may be lit and checked to ensure the smoke and fumes are taken from the stove up the chimney and emitted safely to atmosphere. Do not run at full output for at least 24 hours. On completion of the installation and commissioning ensure that the operating instructions for the stove are left with the customer. Ensure to advise the customer on the correct use of the appliance with the fuels likely to be used on the stove and warn them to use only the recommended fuels for the stove. Advise the user what to do should smoke or fumes be emitted from the stove. The customer should be warned to use a fireguard to BS 6539 in the presence of children, aged and/or infirm persons. Operating your stove – UNIQ 15,16, 20 Initial lighting The heat-resistant paint on your stove will cure and harden the first time you light your appliance. The curing process produces a good deal of smoke and odour, it is therefore important that the first time you light your stove the room should be well ventilated. During the process it is important to open and close the stove door periodically (every 30mins) during the first couple of firings therefore preventing the door seal cord around the door from sticking and coming away from the door. Once the Heat-resistant paint has hardened; the stove door must be kept closed except when lighting the stove, adding firewood or removing ash in order to prevent flue gas from escaping. Lighting your appliance Quality Firelighters should be used when lighting the stove. (Never use mentholated spirit, petrol or other flammable liquids). Lighting your stove with fire lighters will be more reliable and easier than paper. To light your stove 1. Place a few smaller pieces of dry wood (kindling) in the stove on top of the non toxic firelighters. 2. Fully pull open the air slider (secondary air) and the air slider on ash pan (Primary air) it maybe necessary pull the ash pan drawer open 1cm as well) 3. Light the firelighters close the door. 4. Once the fire has caught, add two pieces of wood measuring approx 20cm with a combined weight of approx 1.4kg and close the door. 5. After approximately 10 minutes when the fire is burning brightly shut the air control on the ash pan. 6. After approximately another 10 minutes close the secondary air slider by 50% (25% on smoke control models), for the stove to burn cleanly plenty of secondary air is needed, do not be tempted to shut the fire down too early as this may cause smoke. At nominal heat output, expect to refuel your stove approximately once an hour. WF 15, WF 16 and WF 20 are all equipped with a control valve for secondary air designed to ensure a plentiful supply of oxygen during firing. When lit, the stove will get very hot and due care must therefore be exercised. Please use a glove when operating levers and dampers. RE-FUELING To re-fuel in the cleanest way. Before refuelling open secondary air value fully, also open primary air slider fully (on ash pan) and leave for 5 minutes. Open door gently, add two pieces of wood measuring approx 20cm with a combined weight of approx 1.4kg and close the door. Leave the air values open for 10 minutes to allow the fire to reach a good temperature. Then close primary air valve (on ash pan) and slide secondary air value to 50% open (75% open on smoke control models). In the event of a chimney fire: Close the air damper and the stove door, and call 999 or your local fire department. If your stove is over heating close all dampers and door must be closed, and left until the stove has return to nominal temperatures’. SMOKE CONTROL ZONES Burning your stove in a smoke control zone. The Westfire 15, 16 and 20 are registered to burn in a smoke controlled area. You must purchase a smoke control version which is altered sslightly to comply with regulations. This stove can not be altered, if it is it will not comply with regulations. Basic Positions of dampers during Operation You will need to become familiar with your stove in order to be able to regulate the secondary air intake correctly, as factors facto such as the quality and height of your chimney, the quality of your fuel and the external condition conditionss play a large role in your stove performance. It is easy to see whether the stove is functioning correctly; however incomplete combustion may lead to a build-up build up of hard, shiny soot on the inside of your stove and glass. To prevent sooting of the chamber and glass introduce secondary air, also check that your wood is dry. It is important to check the draft conditions before lighting your stove. This may be done, for instance, by crumpling a piece piec of newspaper, placing it in the combustion chamber and lighting ing it. The draft conditions are good if the smoke is drawn away through the chimney. CONTROLS on WESTFIRE UNIQ 15,16 & 20 Door operation When opening the door of your Westfire stove always wear the glove that is provided to protect your hand from pos possible sible heat. The handle twists right away from the fire. When shutting the door push the door closed and twist left until the handle firmly closes. WOOD FUEL IMPORTANT: Never use toxic wood such as chipboard, impregnated or painted wood. Good quality wood is the most important factor in your stove working efficiently and cleanly. Always use dry firewood. The dryness of the firew firewood plays an important role since the use of wet wood results in poor fuel economy and may cause a tarry sooty film on the internals internals of the stove. Newly cut wood contains 60–70% 70% water, making it totally unsuitable for use as firewood. Newly cut wood should be stacked and air dried under cover for two years before being used as firewood. SOLID SMOKELESS FUELS – Westfire stoves are only only CE/EN/HETAS tested and approved for wood. It is possible, however, to use other types of fuel with due care. When using coal/smokeless fuel you must use a coal insert and a mix of 80% wood, 20% coal. Please note coal reduces the lifetime of the stove and the chimney considerably. PETROLEUM COKE IS NOT SUITABLE FOR USE ON THIS STOVE; ITS USE WILL INVALIDATE THE GUARANTEE Overnight burning Westfire stoves are wood stoves, wood burns more efficiently and cleanly if is burnt hotter. Westfire do not recommend that their stoves are burnt overnight for this reason. As a night time regime we recommend that the fire is loaded when hot and burnt for five minutes with the secondary air valve fully open until the new wood has taken and is burning, then close the secondary air valve to its operational position. On returning to the stove in the morning the fire will have burn out, reload with some paper or firelighter and some kindling and open all the values fully open and the stove will relight quickly. Beware as the ash bed will have hot embers. Use of operating tools Always use the operating tools provided when handling parts likely to be hot when the stove is in use. Maintenance UNIQ 15,16, & 20 wood stove needs to have the ash removed from the stove at regular intervals. Make sure the stove is completely cold before cleaning out ash (embers can remain hot for over 24 hours). To clean the outside of the stove use a dry cloth. Annual service The inside of the stove should be serviced /cleaned once a year. To clean the inside, remove all ash, soot and tar residue from the combustion chamber. Remove insulated chamber panels and baffle, dirt and soot will collect behind it and this must be cleaned out. Check the quality of all insulated panels and replace any which are damaged or cracked, replace stove door rope cord in the door. Check glass is correctly positioned. The stove, the flue pipe connection and the chimney should be checked regularly by a qualified engineer. The chimney should also be checked for blockages before relighting the stove if it has not been used for an extended period of time. The paint/ lacquer can wear thin in exposed places due to overheating. This, and other lacquer damage, may be repaired using a Westfire Senotherm paint/lacquer spray available from your Westfire dealer. Ash must be stored in a non-combustible container and must not be mixed with other combustible waste. TROUBLE SHOOTING, CHECK THE FOLLOWING: 1. Fire Will Not Burn a) the air inlet is not obstructed in any way, b) that chimneys and flueways are clear, c) that a suitable fuel is being used, d) that there is an adequate air supply into the room, e) that an extractor fan is not fitted in the same room as the fire. 2. Fire Blazing Out Of Control a) the doors are tightly closed, b) the air control is turned down to the minimum setting, c) the air inlet damper is closed and that it is not prevented from closing completely by a piece of ash, d) a suitable fuel is being used, e) the door seals are in good condition. f) the chimney draft may be too strong g) check ash pan seal and h) check for ash below ash pan causing pan to not seat correctly and clean out. 3. Soot forms on the window a) The firewood may be too wet b) the intake of secondary air may be insufficient c) fire not hot enough 4. The stove fails to heat fully a) The firewood may be too wet b) the intake of secondary air may be insufficient 5. Smoke or odour a) Weak chimney draft b) check for blockages in the flue pipe/chimney c) check the height of the chimney in relation to the surroundings 6. Soot in the chimney a) The firewood may be too wet b) intake of secondary air may be insufficient Chimney Fires If the chimney is thoroughly and regularly swept, chimney fires should not occur. However, if a chimney fire does occur turn the air control setting to the minimum, and tightly close the doors of the stove. This should cause the chimney fire to go out in which case the control should be kept at the minimum setting until the fire in the stove has gone out. The chimney and flueways should then be cleaned. If the chimney fire does not go out when the above action is taken then the fire brigade should be called immediately. After a chimney fire the chimney should be carefully examined for any damage. Expert advice should be sought if necessary. Permanent air vent The stove requires a permanent and adequate air supply in order for it to operate safely and efficiently. In accordance with current Building Regulations the installer may have fitted a permanent air supply vent into the room in which the stove is installed to provide combustion air. This air vent should not under any circumstances be shut off or sealed. WARNING NOTE Properly installed, operated and maintained this stove will not emit fumes into the dwelling. Occasional fumes from de ashing and re fuelling may occur. However, persistent fume emission is potentially dangerous and must not be tolerated. If fume emission does persist, then the following immediate action should be taken: (a) (b) (c) (d) Open doors and windows to ventilate room Let the fire out or eject and safely dispose of fuel from the appliance Check for flue or chimney blockage and clean if required Do not attempt to relight the fire until the cause of the fume emission has been identified and corrected. If necessary seek expert advice. The most common cause of fume emission is flueway or chimney blockage. For your own safety these must be kept clean at all times. IMPORTANT NOTES General Before lighting the stove check with the installer that the installation work and commissioning checks described in the installation instructions have been carried out correctly and that the chimney has been swept clean, is sound and free from any obstructions. As part of the stoves’ commissioning and handover the installer should have shown you how to operate the stove correctly. Use of fireguard When using the stove in situations where children, aged and/or infirm persons are present a fireguard must be used to prevent accidental contact with the stove. The fireguard should be manufactured in accordance with BS 6539. Chimney cleaning The chimney should be swept at least once a year for smokeless fuels and a minimum of twice a year for wood and other fuels. It is important that the flue connection and chimney are swept prior to lighting up after a prolonged shutdown period. If the stove is fitted in place of an open fire then the chimney should be swept one month after installation to clear any soot falls which may have occurred due to the difference in combustion between the stove and the open fire. In situations where it is not possible to sweep through the stove the installer will have provided alternative means, such as a soot door. After sweeping the chimney the stove flue outlet and the flue pipe connecting the stove to the chimney must be cleaned with a flue brush.
