Firestorm Stoves 10KW MULTI-FUEL STOVE INSTALLATION & USER INSTRUCTIONS 10Kw 6.5Kw 4.5Kw Firestorm Stoves Welcome Court, Unit 2 Bracewell Avenue, Poulton Business Park Poulton-Le-Fylde, Lancashire FY6 8JF Tel: 01253885554 Fax: 01253 885585 Web: www.firestormstove.co.uk Email: [email protected] Installation Instructions The installer has a responsibility under the Health and Safety at Work Act 1974 to provide for the safety of persons carrying out the installation. Attention is drawn to the fact that fire cement is caustic and hands must be washed thoroughly after use. The appliance is heavy and care must be taken during handling. Although the appliance does not contain asbestos products, it is possible that asbestos may be disturbed in existing installations and every precaution must be taken. These instructions give a guide for the installation of the appliance but in no way absolves the installer from responsibilities to confirm to British Standards, in particular BS8303 and BS6461, relating to the installation of solid fuel appliances. All local regulations, including those referring to National and European standards need to be complied with when installing the appliance. Chimney & Flue The successful operation of these appliances relies on the adequate performance of the chimney to which it is connected. The chimney must: o Have an internal cross section of not less than 320 Cm.sq (200mm Dia.). (If a flue liner is used it should be not less than 150mm diameter and suitable for solid fuel and comply with 2010 approved document J:2.6 ). o Be a minimum 4.6m high from hearth level to pot. o Be terminated at least 1m above roof level so that the chimney does not terminate in a pressure zone. o Be free from cracks, severe bends, voids, and obstructions. o Be connected to this one appliance only. o New chimneys must be built in accordance with local building regulations. o Existing chimneys must be tested in accordance with HETAS requirements. o If the stove is installed as a freestanding appliance, it should not support any part of the chimney. o Voids in the chimney should be avoided, as these will prevent a steady flue draught. o The stove flue pipe should pass beyond the narrowing of the chimney. See Fig.1 o Consideration should be given to falling soot. For rear outlet stoves it may be necessary to provide soot catchment area in the form of a 90 degree tee with removable soot door at the rear connection. o A flue/chimney access point may also be required so that the state of the chimney can be checked and any fallen soot removed. o External flues must be insulated to prevent heat loss. o All stoves need air to breath, any stove with an output above 5 KW needs a permanent air supply into the room in which the stove is to be installed. This should be at least 550 mm’’ per KW output pf appliance. Please check current building regulations document j on the current ventilation requirement at the time of installation. Ideal Flue Connection Fig 1 Flue Draught The chimney can be checked, before the stove is installed, with a smoke match. If the chimney doesn’t pull the smoke it may suggest the chimney needs attention. Measurement: The flue draught test hole must be drilled in the flue pipe as close to the stove as possible and before any flue draught stabiliser. Minimum: The stove should be lit and allowed to warm the flue thoroughly. The air controls can then be set so that the stove burns on a low setting. Allow the burning rate to become steady. The flue draught reading should now be taken with the primary air intake closed and the airwash control fully open. Maximum: The primary air intake can now be opened to allow the stove to burn at maximum rate. Give the stove some time for the burning rate to become steady and then close the primary air intake, make sure the air-wash control is fully open and take a flue draught reading immediately. Ideally, the flue draught readings should range between 1mm wg and 2.5wg .Any readings significantly outside this range may indicate the need for remedial action. Note: This test is only a guide as an apparently poor flue may improve once the stove is installed, lit and the flue is warmed. If, once the stove is installed, there is any doubt that the chimney is providing an adequate draught; a flue draught reading can be taken with the stove lit. Two flue draught readings should be taken, one with the stove at minimum firing rate and one at maximum firing rate. Flue Stabilizer A flue stabilizer can be fitted to reduce the draught through the stove if the flue draught is too high. The flue stabilizer should be: • fitted in the same room as the stove • The same size as the flue pipe • fitted no closer than 700mm to the flue outlet of the appliance. Installing the Stove This appliance is not suitable for installation on any water born vessel, caravans or any form of mobile home. Clearances From Combustibles Side 750mm Rear 950mm Stove Weight 126Kg Positioning: The overall dimension of the stove is shown in above. The table above indicates recommended distances between the stove and surrounding combustible materials. As a rule, any surrounding combustible material should not exceed 80°C. There should be sufficient space around the stove for service work. Hearth: The construction of the hearth must conform to Building Regulations, must be firm, non- combustible and capable of supporting the stove. (Refer to Building Regulations Document J). Flue Connection: The flue pipe used to connect the stove to the chimney is 5” (125mm) in diameter. The stove is supplied ready for top flue or rear flue connection. To change to rear connection the flue blanking plug supplied with the stove is used to block the top flue outlet. The blanking plug in the rear flue connection must then be removed. Important Installation Notes: 1. The installation must allow for adequate chimney sweeping. 2. Avoid using bends greater than 45° to the vertical. All flue pipe sections should be as close to vertical as possible. 3. All joints in the flue system must be effectively sealed. 4. All flue sockets must face upwards. 5. Check the appliance for soundness of seals between castings and main components and that all supplied parts and fittings are correctly fitted. 6. Ensure that there is no extractor fitted in the same room as the appliance. 7. The chimney must be swept and examined for soundness and suitability before the appliance is installed. Remedial action should be taken if required, seeking expert advice if necessary. Where the chimney is believed to have previously served an open fire installation it is possible that the higher flue gas temperature from a closed appliance may loosen deposits that were previously firmly adhered, with the consequent risk of flue blockage. It is therefore recommended that the chimney be swept a second time within a month of regular use after installation. 8. The installer is to check under fire that the appliance operates correctly and to check for soundness of seals/joints. Check also that the flue functions correctly and that all products of combustion are vented to atmosphere through the chimney terminal. 9.Commissioning and handover instructions:- Ensure all parts are fitted in accordance with the instructions. On completion of the installation allow a suitable period of time for any fire cement and mortar to dry out, before lighting the stove. Once the stove is under fire check all seals for soundness and check that the flue is functioning correctly and that all products of combustion are vented safely to atmosphere via the chimney terminal.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 and warn them to use only the recommended fuel 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 8423:2002 (Replaces BS 6539) in the presence of children, aged and/or infirm persons. 10. The installer must comply with the current issues of British Standards BS EN 15287-1:2007 design, installation and commissioning of chimneys. 11. The installer is to leave the appliance operational with the heating system correctly balanced and to hand over User Instructions and any operating tools supplied. The installer should explain the operation of the appliance to the user. 12. The installer is to fit a CO alarm in accordance with the guidelines given in Approved Document J of The Building Regulations. CO Alarms:- Building regulations require that whenever a new or replacement fixed solid fuel or wood/biomass appliance is installed in a dwelling a carbon monoxide alarm must be fitted in the same room as the appliance. Further guidance on the installation of the carbon monoxide alarm is available in BS EN 50292:2002 and from the alarm manufacturer’s instructions. Provision of an alarm must not be considered a substitute for either installing the appliance correctly or ensuring regular servicing and maintenance of the appliance and chimney system. On completing the installation, check that all the internal components of the stove are positioned correctly. Check - ash pan, iron grate, baffle, side and back bricks. Arranging the flue plug for top or rear outlet See Fig.2 Recomended Fuel For best results use well seasoned hardwood such as Oak, Ash, or Beech.
