PUMICE SYSTEM CHIMNEYS & LINERS ...naturally better UPDATED RANGE INCLUDING THE NEW CE APPROVED MAGNUM FIRECHEST DOC/CP3/64 SAP Issue 2 May 2014 Part of the BRAAS MONIER BUILDING GROUP Pumice - naturally better Pumice is a natural insulator. This is the unique property that separates pumice from all other chimney materials. The insulating properties of Pumice allow the flue gases in the chimney to quickly reach their optimum temperature enabling the heating appliance to reach its optimum performance shortly after lighting. It also keeps the chimney warmer longer as the heat output of the appliance decreases - once again aiding performance and reducing the likelihood of condensation and soot build-up. The natural properties of pumice Resistant to temperature change Pumice has very little expansion and contraction with temperature change. This reduces the possibility of cracking and structural damage that can occur with other products. High Insulation Properties Pumice is a natural insulator, able to maintain the temperature of flue gases when other products have allowed the temperature to fall below the dew point. Lightweight Pumice is strong yet lightweight allowing one person to lift and build the chimney units. Pumice is a natural material sourced from the Hekla Volcano in Iceland. Pumice is an excellent insulator, keeping flue gases warm while not transmitting heat to the outside. Product Description Schiedel Isokern products can be used for new chimneys and for the refurbishment of existing chimneys. The Isokern chimney systems provide a lightweight, easily installed and versatile chimney which can be used internally or externally.The systems are suitable for use with burning appliances in new and refurbished projects.They are ideal for Masonry,Timber Frame and Steel Frame construction. Isokern chimneys have been installed in Europe for over 60 years. 2 DM (DOUBLE MODULE) FLUE LINERS Schiedel Isokern DM block system is a high quality System Chimney. The double wall system maintains flue gas temperatures while preventing heat transference to the outer casing. The separation of the inner and outer components also allows for thermal movement, reducing the risk of cracking and subsequent leaking or staining. It is simple and quick to build. The DM is available in 3 outer casing sizes - DM36, DM44 & DM54. The Schiedel Isokern flue liner range consists of over 15 different sizes. They can be used for newbuild, extensions and relining existing chimneys. FIRECHESTS ISOKOAT FLUE SEALING SYSTEM The Schiedel Isokern range of firechests are supplied as flat packs.They can be easily and quickly constructed to produce a neat and pre-formed fire opening ready for finishing. The Magnum Firechest provides the opportunity to create fire openings up to 1.2m wide. The Schiedel Isokoat system is an efficient and cost effective method of re-sealing a defective chimney shaft. The Isokoat material is applied to the chimney under pressure and forced into the cracks sealing them, re-pointing the joints and strengthening the walls. For further details see the separate Isokoat leaflet. DM Double Module Chimney System When the ease of construction and maximum insulation matter then the Double Module System comes into its own. The system is designed to be quick and easy to install. The lightweight blocks are easy to handle. The outer and inner blocks are laid at the same time but with staggered joints for safety and stability. The double layer of pumice blocks separated by an air gap maximises the chimney insulation. The Pumice Systems are suitable for wood - logs and chips, solid fuel, oil and gas. There are 3 systems covering a range of different internal diameters to meet the requirements of different appliances and uses: DM 36 150mm internal diameter for smaller output inserts, stoves and solid fuel/oil cookers DM 44 180mm and 200mm internal diameters for inserts, stoves and open fires DM 54 300mm and 345mm internal diameters for Magnum firechests and larger appliances - inserts and open fires Unique features of the Isokern DM Chimney System Zero distance to combustibles on straight rendered chimneys Quick and easy to assemble Lightweight materials, easy to handle Highly insulating pumice for better draw and minimum heat loss Staggered joints for maximum safety and stability Air gaps between outer casing and flue prevents surface staining Good resistance to temperature variations gives the maximum performance for your appliance Approvals Isokern Pumice Double Module DM is CE Certified to EN1858 TÜV Cert no. 0036 CPD 90219 001 Isokern Pumice Chimney Liner is CE certified to EN1857 TÜV Cert no. 0036 CPD 90219 002 Isokern Magnum Firechest has been tested at the Fraunhofer Institut, Stuttgart, Cert no.

OPEN FIRE OPTION Bed the base plate of the firechest onto a suitable foundation/constructional hearth in accordance with Building Regulations and at the level required on site using Isokern lip glue. Install the firechest using lip glue making sure all elements are level. 100mm of brick/blockwork must be built around the sides and back of the firechest to comply with Building Regulations. The inside of the firechest must be finished with a suitable fireback or firebrick slips. Install the gather using lip glue making sure all the elements are level. The front face of the gather can be finished with plasterboard, rendered or clad in masonry. Lintels may be required above the gather to help carry the brick or blockwork.The maximum loading capacity of the ISOKERN firechest and gather is 2500kg. STOVE IN RECESS OPTION Pre-stressed lintels or a suitable cast-in-situ concrete slab must be provided above the stove recess, please make sure they are strong enough to carry the load (see appropriate Isokern DM drawing for aperture size). It is recommended to have a minimum of 600mm of stove flue pipe before connecting to the support block. The support block is bedded onto the lintels using a weak mix mortar. A stainless steel adaptor is used to create a positive connection from the support block to the stove flue pipe (fibre rope should be used to create a seal). Lintels Support block Stainless steel adaptor STOVE IN RECESS OPTION Gather elements Magnum firechest Firebrick slips Suitable foundation FREE STANDING STOVE OPTION A soot door casing and access flue block must be used below the flue pipe entry. The DM 45˚ access kit is then used for the connecting flue pipe. A suitable wall sleeve must be used to seal the cavity wall. Any combustible insulation within the wall must then be kept away from the single wall connecting flue pipe by at least 1.5 x its diameter. Fibre rope is used to seal between the flue pipe and wall sleeve, a suitable trim collar can be used to finish the inner wall surface. OPEN FIRE OPTION Flue entry kit Wall sleeve and fibre rope seal Prima flue pipe Soot door casing FREE STANDING STOVE OPTION 10 Typical DM Installation Detail CHIMNEY CONSTRUCTION Bed the first outer casing using lip glue making sure the rebate (raised lip) is uppermost. The starter flue block is then put inside the casing bedded with lip glue. The socket on the starter flue block must be uppermost and the air gap between the starter flue and the casing should be kept clear. Lip glue joints should be approximately 2mm thick, a special bag is provided for ease of application. Remove any excess glue to maintain a smooth surface. Where a straight chimney passes through a floor or roof, zero mm distance to combustibles can be applied. A sliding joint is made using mineral wool or similar non-combustible material. On an offset chimney, 38mm clearance must be maintained between the outer face of the chimney and any structural timber or loose combustible material. Floor boards, skirting boards, dado rails and other non-structural components may, however, be in contact with the chimney. Lip glue Inner flue blocks Void to be kept clear Lip glue Non combustible material 38mm clearance from structural timber HOW TO USE LIP GLUE Offset blocks ‘if required’ must be used immediately above the support block or firechest gather. They must be glued together with lip glue and be fully supported. Please note a chimney should be built straight wherever possible. A starter flue block will be required above the offset blocks to stagger the joints between the outer casing and inner flue blocks. External chimneys must be tied to the structure at maximum intervals of 1.5m and at the point where it departs from the roof using 2 x suitable stainless steel wall ties. These are fitted into the outer casing joints. They are not always required for internal chimneys. Please consult the Isokern technical office. Stainless steel ties Starter flue block Offset blocks must be fully supported and bedded with lip glue DM outer casings Load bearing support Casings and flue blocks are added using lip glue for all joints. Ensure the air gap between the inner flue and outer casing remains clear.The outer surface of the casings to be finished with plasterboard on dabs or plaster. The side that faces the wall does not need an external finish. High tensile steel reinforcement rods will be required for all chimneys with a height that exceeds 1.4m above the roof line, 1.1m if the wind speed exceeds 44ms. These rods are available from Isokern and must be grouted (1:3 cement/ sand) into the holes provided in the outer casings.You must start the rods at least the same height below the roof as what’s above, please check with our technical department. Reinforcement rods Plasterboard DM outer casing 11 Typical DM Installation Detail RENDERED STACK OPTION Code 4 lead flashing to be fitted at roof level as per Building Regulations. We recommend that you scorch a 5-10mm deep channel into the outer surface of the casings and fold in the top edge of the flashing. Finish the outer surface of the casings above the roof with 2 part waterproof render. The recommended mix is 1:2:5-6 cement:lime:sand for the undercoats. 1:2:8-9 cement:lime:sand for the final coat. The number of coats required will depend upon the degree of exposure, generally a two coat mix is acceptable. The mix may vary due to climate conditions, the thickness of any one coat should not exceed 15mm, and each subsequent coat should be reduced by approximately 3mm. Isokern concrete capping for render to be lip glued onto the last casing. 10mm gap for ventilation under Top Ring Capping for render Waterproof render Code 4 lead flashing (not supplied) RENDERED STACK BRICK STACK OPTION To take brick or stonework externally a corbel is fitted just below the roof. Use trusses and trimmers to brace the cladding as it passes through the roof. Code 4 lead tray with 50mm upstands and stepped flashing to be fitted in accordance with Building Regulations. A 50mm upstand should be fitted tight to the outside of the flue block and where possible turned in by approx 10mm. Lead trays should be coated with bituminous paint where it is in contact with mortar. The D.P.C. tray should be fitted at least 150mm above the lowest point of intersection with the roof. Weep holes should be provided at the front of the stack above the tray for water drainage. Casings can be deleted above the corbel if stack height is less than 1.4m above the roof. 12 Flue block or chimney pot Lead tray and flashing Weep holes above tray Corbel for brick stack BRICKWORK STACK TERMINATION Raincap - Ventilated Option - (Installation with 0 distance to combustibles for straight rendered chimneys only). Take the last flue block up through the capping, do not fill the gap between the flue block and capping. Push fit the aluminium top ring onto the flue block and make sure there is a 10mm air gap between the outer edge of the ring and the capping. The flue block may need cutting to suit. Chimney Pot Option - This option always requires a 38mm distance to combustibles from the outside of the block. Fit a chimney pot at least 75mm down into the capping and flaunch with 1:3 cement and sharp sand to seal around. This option is not possible if 0 distance to combustibles is required. AFTER COMPLETION After installation is complete tests and checks should be carried out in accordance with document J of the Building Regulations. A chimney notice plate must be completed and permanently fixed in the dwelling, ideally near the electrical consumer unit. The checklist and notice plate are available from Schiedel Isokern. USE AND MAINTENANCE The chimney should be left for at least 72 hours before use, then start only with small fires for the first week and gently increase thereafter. The chimney should be swept at least twice a year, once before the heating season and once after the heating season. You may need to sweep during the heating season depending upon use. The brush should be a medium density polypropylene bristle type and should be the same diameter as the flue. Steel brushes must not be used to sweep the Isokern pumice flues. Always follow the appliance manufacturer’s operating instructions. Always burn approved fuels or dry seasoned wood. Avoid burning unseasoned wood and slow burning of solid fuels as this can produce excessive soot and condensation which in turn cause soot fires and damage. If correctly installed, operated and maintained these systems should last the life of the dwelling. Liner System - for new and existing chimneys The pumice liner system comes in a range of 15 diameters from 150mm to 1000mm with T Liners, Liner Support Blocks, and Adaptors for ease of connection to the appliance.

(See Isokern standard drawings for hole size depending on diameter of chosen flue). 45˚ Wall sleeve Soot door Alternatively you could use suitable pre stressed lintels, for this method a support plate is required under the support block. It is recommended to have a minimum of 600mm length of flue pipe before connecting to the chimney. The support block is bedded onto the slab lintel using weak mix mortar. A stainless steel adaptor is used to connect from the support block to the stove flue pipe. This adaptor is pushed up onto the support block spigot (fibre rope should be used to create a seal). Support block Cast -in-situ slab FREE STANDING STOVE OPTION OPEN FIRE OPTION Install the firechest onto the constructional hearth using lip glue making sure all elements are level. 100mm of brick or blockwork must be built around the sides and back of the firechest to comply with Building Regulations. The inside of the firechest must be finished with a suitable fireback or firebrick slips. Install the gather using lip glue making sure all elements are level. The front face of the gather can be finished with plasterboard, rendered or clad in masonry. Lintels may be required above the gather to help carry the brick or blockwork. The maximum loading capacity of the Isokern firechest and gather is 2500kg. STOVE IN RECESS OPTION FREE STANDING STOVE OPTION A soot door must be provided below the flue pipe entry to allow for inspection and removal of soot and debris. A suitable wall sleeve is to be used to seal the cavity wall. Any combustible insulation within the wall must be kept away from the single skin connecting flue pipe by at least 1.5 x its diameter. A stainless steel adaptor is glued to the Isokern T Liner with lip glue. The flue pipe is a push fit over the spigot on the adaptor. Seal off the gap between the flue pipe and wall sleeve with fire proof rope and closing plate. Voids filled with Leca mix Suitable lintel Magnum firechest Firebrick lining OPEN FIRE OPTION 17 Typical Liner Installation Detail ALL OPTIONS The flue liners are installed socket uppermost and sealed with Isokern lip glue. Lip glue joints should be approximately 2mm thick. A special bag is provided for ease of application. Remove any excess glue to maintain a smooth surface. Clad the liners with a minimum of 100mm thick suitable masonry. A minimum thickness of 15mm leca insulation must be installed between the liners and masonry. Mix 20 parts leca to 1 part opc cement and a small amount of water. Make sure it is well mixed before using. ue Gl Lip Fit appropriate lead dpc’s and flashings in accordance with the relevant regulations. Isokern recommend that the lead tray should be dressed up the outside of the flue liners to avoid a weak joint. Weep holes should be provided above the tray for moisture drainage. Terminate the chimney to the correct height in accordance with document J of the Building Regulations. The chimney can be finished by flaunching (1:3 cement/sharp sand) either around the Isokern flue liner or a suitable chimney pot. Approved rain caps can be used to help prevent water entering the flue. Liner or chimney pot Liners with socket uppermost Direction of flue gases Joints sealed with lip glue Leca insulation If bends are required in the chimney make sure adequate support is provided and always backfill with leca insulation mix. Liners can be cut between bends to achieve a required offset distance. A steel collar as well as lip glue must be used for any cut joints. A maximum of 2 complete offsets (4 bends) are allowed per chimney and the angle must not be greater than 45˚ from the vertical. Flaunching Weep holes above tray Lead tray and flashing AFTER COMPLETION After installation is complete tests and checks should be carried out in accordance with document J of the Building Regulations. A chimney notice plate must be completed and permanently fixed in the dwelling, ideally near the electrical consumer unit. The checklist and notice plate are available from Schiedel Isokern. USE AND MAINTENANCE The chimney should be left for at least 72 hours before use, then start with only small fires for the first week and gently increase thereafter. Collar around cut joint You must provide adequate clearance from combustible material in accordance with Building Regulations. Combustible materials must be 200mm from the inner surface of flue liner or 40mm from the outside of the masonry chimney unless it is a floorboard, skirting board, dado or picture rail, mantel-shelf or architrave. 18 The chimney should be swept at least twice a year, once before the heating season and once after the heating season. You may need to sweep during the heating season depending upon use. The brush should be a medium density polypropylene bristle type and should be the same diameter as the flue. Steel brushes must not be used to sweep Isokern pumice flues. Always follow the appliance manufacturer’s operating instructions. Always burn approved fuels or dry seasoned wood. Avoid burning unseasoned wood and slow burning of solid fuels as this can produce excessive soot and condensation which can in turn cause soot fires and damage. If correctly installed, operated and maintained these systems should last the life of the dwelling. Useful Charts and Information FLUE AREA AND LIP GLUE QUANTITY CHART Int.

For clearances to easily ignitable roof coverings such as thatch refer to diagram 2.2 of Approved Document J 2010 Edition 20 Useful Charts and Information VENTILATION REQUIREMENTS It is very important that sufficient air for combustion and ventilation is provided to the room containing the appliance, to enable correct and efficient working of the appliance and chimney system. Reference should be made to the appliance manufacturer’s instructions and recommendations are also given in the Building Regulations Document J, see below: CARBON MONOXIDE ALARMS Where a new or replacement fixed solid fuel appliance is installed in a dwelling, a carbon monoxide alarm should be provided in the room where the appliance is located. The carbon monoxide alarms should comply with BS EN 50291:2001. The carbon monoxide alarm must be located in the same room as the appliance: 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 b) between 1m and 3m horizontally from the appliance. N.B Provision of a carbon monoxide alarm should not be regarded as a substitute for correct installation and regular servicing. VENTILATION REQUIREMENTS FOR SOLID FUEL Type of Appliance Type and amount of Ventilation (1) Open appliance, such as an open fire with no throat, e.g. a fire under a canopy as in Diagram 23. Permanently open air vent(s) with a total equivalent area of at least 50% of the cross sectional area of the flue. Open appliance, such as an open fire with a throat, as in Diagrams 22 and 29. Permanently open air vent(s) with a total equivalent area of at least 50% of the throat opening area. (2) Other appliance, such as a stove, cooker or boiler, with a flue draught stabiliser. Permanently open air vents as below: If design air permeability > 5.0m3/(h.m2) then 300mm2/kW for first 5kW of appliance rated output 850mm2/kW for balance of appliance rated output If design air permeability ≤ 5.0m3/(h.m2) then 850mm2/kW of appliance rated output (4) Other appliance, such as a stove, cooker or boiler, with no flue draught stabiliser. Permanently open vents as below: If design air permeability > 5.0m3/(h.m2) then 550mm2/kW of appliance rated output above 5kW If design air permeability ≤ 5.0m3/(h.m2) then 550mm2/kW of appliance rated output (4) Notes: 1. Equivalent area is as measured according to the method in BS EN 13141-1:2004 or estimated according to paragraph 1.14. Divide the area given in mm2 by 100 to find the corresponding area in cm2. 2. For simple open fires as depicted in Diagram 29, the requirement can be met with room ventilation areas as follows: Nominal fire size (fireplace opening size) Total equivalent area of permanently open air vents 500mm 450mm 400mm 350mm 20,500mm2 18,500mm2 16,500mm2 14,500mm2 3. Example: an appliance with a flue draught stabiliser and a rated output of 7kW would require an equivalent area of (5 x 300) + (2 x 850) = 3200mm2 4. It is unlikely that a dwelling constructed prior to 2008 will have an air permeability of less than 5.0m3/h.m2) at 50Pa unless extensive measures have been taken to improve air-tightness.

The finished appearance is down to individual taste using one of the many fireplace surrounds on the market. The Schiedel Isokern firechest complements the Isokern chimney systems which are designed to create a complete system, avoiding many of the variable factors that lead to draught problems and smoky fireplaces. The Isokern firechest range is cast using lightweight, highly insulating pumice.The components interlock like pieces of a three dimensional jigsaw to form a sturdy, robust fireplace recess and gather.The joints are sealed using lip glue jointing compound. Starting from a suitable foundation and constructional hearth, assembly of the complete firechest and gather could take less than one hour. The range includes firechests with fire openings from 500 to 1250mm and a recess designed specifically for stoves. Each firechest is packed on a pallet with detailed assembly instructions. The firechest is load bearing and will carry up to 2600kg of chimney above, although you may exceed this weight with the use of additional lintels. The NEW Magnum Firechest Range The new Magnum Firechest range has been designed to maximise the burning efficiency of wood in an open fire.The specially shaped fire chamber facilitates the efficient burning of wood logs to give efficiencies from 41% to 45%, depending on the model chosen. The firechests are tested to EN13229. DAMPER A flue damper is available in the Magnum range of firechests. In wood burning installations the flue damper can be used to control the draft in the flue and avoid excessive heat loss when the fireplace is not being used. This is reflected in the SAP calculation for Document L.The inclusion of the damper will halve the chimney ventilation rate in the SAP calculation. It must not be installed with gas fires.
