MANDATORY REQUIREMENTS
Connection to an appliance which is not connected to the fuel supply, should be carried out by a competent person. We recommend the use of HETAS approved installers for solid fuel applications. If installation is carried out by a non HETAS registered installer, the installation must be certified by a local Building Control inspector. Connection to an appliance that is connected to the fuel supply must be carried out by a Gas Safe (Gas) or OFTEC (Oil) registered installer.
The design guide must be read in conjunction with the detailed component installation instructions. For full design and installation details the key referral documents are:
VENTILATION
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, CIBSE guidance notes and BS 5440.
CARBON MONOXIDE ALARMS
The carbon monoxide alarms should comply with BS EN 50291
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.
Please follow manufacturers instructions with regards to siting and fixing or alternatively :-
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.
PAINTING
On high temperature applications,where ICID Plus is being connected directly to the stove, then a high temperature paint specification must be used on all appliance connectors and components used within 2 meters of the appliance outlet. See Schiedel ICID Plus catalogue for details of Schiedel High Temperature Paint spec. If painting of any external sections is required, it is important to de-grease, dry and prime the exterior surface prior to the application of appropriate heat resistant paint. Schiedel Chimney Systems can provide to special order, chimney sections and accessories painted to an extensive range of British Standard RAL colours – details on application.
HANDLING
It is advised that suitable PPE should be used when handling the products.
DELIVERY TO SITE AND STORAGE
Components should be carefully transported and off loaded. They should be inspected to ensure they have not been damaged, and should be stored off the ground and under cover so that they are protected from accidental damage and the adverse effects of weather.
APPLIANCE/CHIMNEY CONNECTION
Connection to the appliance can be made using Prima Smooth, Prima Plus or alternative approved single wall connecting flue pipes, or ICID Plus. Where painted product is used on a high temperature application, then this must be a high temperature paint specification. See latest Schiedel ICID Plus catalogue for details of Schiedel High Temperature Paint spec.
The connection must be made by using the appropriate appliance connector. When a single wall connecting flue pipe is used to connect an appliance to the chimney, the lower end of the insulated chimney section must extend a minimum of 425mm below the ceiling. When connecting the appliance to the flue pipe all joints between the flue pipe/appliance outlet must be securely caulked and sealed with non asbestos rope (or suitable alternative) and fire cement on solid fuel appliances.
Any flue pipe connection to the chimney MUST be made in the same room as the appliance.
PROVISION FOR CONDENSATE DISPOSAL (SUBJECT TO APPLIANCE MANUFACTURERS’ RECOMMENDATIONS)
Condensing appliances need provision for drainage. Choose the appropriate flue drainage components normally fitted at the base of the vertical stack and/or close to the appliance outlet. Any ‘horizontal’ runs must allow for a minimum 3° slope and therefore, where required, 87° bends and 93° tees must be used rather than 90° bends and tees.
CONNECTION TO DRAUGHT DIVERTER
Where the appliance features a draught diverter the connection should rise vertically from it for at least 600mm before any change of direction (unless otherwise specified by the appliance manufacturer). This is in accordance with the recommendations contained in BS 5440 Part 1 section 6.1.4
CONNECTING FLUE PIPE DIAMETER
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.
DISTANCE TO COMBUSTIBLES
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 Ø Int of the pipe, with an absolute minimum of 375mm e.g. on both Ø100 and Ø125mm pipe, the distance to combustibles is 375mm and for Ø150 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. On ICID Plus this distance has been measured and is set at 100mm.
CONNECTING FLUE PIPE ROUTE
Single wall 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 Ceramic,Pumice or brick chimney attached to the building and passing directly into the chimney through the wall. Distance to combustibles must be maintained within the wall space. In order to guarantee this, we recommend the use of our Ignis Protect product.
Within the room where the appliance is situated, connecting flue pipes should be located so as to avoid igniting combustible material.
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.7-8 for full details.)
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.
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. (See p.7-8 for full details.)
Within a system (Connecting Flue Pipe + System Chimney) servicing a solid fuel appliance, there should be no more than 4 changes of direction of maximum 45˚. 90˚ Factory made bends or tees within the system may be treated as being equal to two 45˚ bends (as per Document J of the Building Regulations issued October 2010).
INSPECTION
On solid fuel applications, to conform to Building Regulations, provisions should be made to enable a chimney to be inspected and cleaned.
An inspection pipe, inspection elbow or a 90° or 135° 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 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.
ACCEPTABLE ALTERNATIVE METHODS OF CONNECTION
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:-
Top Outlet Single Wall Connecting Flue Pipe through Solid Wall into Twin Wall System Chimney
NB Where the connecting flue pipe from the appliance passes through any wall other than the existing chimney wall, the connecting flue pipe
must be a System Chimney of twin wall insulated design.
Top Outlet Twin Wall Connecting Flue Pipe through Solid Wall into Twin Wall System Chimney
Top Outlet Twin Wall Connecting Flue Pipe into Re-lined Masonry Chimney
Rear Outlet Twin Wall Connecting Flue Pipe into Re-lined Masonry Chimney
Rear Outlet Twin Wall Connecting Flue Pipe Through Cavity Wall into Twin Wall System Chimney
Rear Outlet Twin Wall Connecting Flue Pipe into External Masonry Chimney through a Cavity Wall
CHIMNEY DIAMETER
The chimney size should be as recommended by the appliance manufacturer. Where there is a requirement for a flue diameter smaller than the appliance spigot, then the operational requirements of the appliance and the configuration of the flue must satisfy the flue sizing requirements of EN13384-1 for single appliances, and EN13384-2 for multi appliances.
CHIMNEY ROUTE
The chimney should remain as straight as possible through its vertical run to assist flow. Should it be necessary to offset a chimney run then the following guidelines should be adhered to:
It is recommended that a vertical run of at least 600mm should be allowed immediately above the appliance prior to any change of direction. On natural draught systems on any fuel, it is recommended that there should be no more than 4 changes of direction of maximum 45°. Factory made 90° bends or tees within the system may be treated as being equal to two 45° bends (On fan flued appliances, a calculation should be carried out according to BS EN 13384 to ensure that any installation requiring more than 4 changes of direction will satisfy the flue sizing requirements).
CONNECTION TO DRAUGHT DIVERTER
Where the appliance features a draught diverter the connection should rise vertically from it for at least 600mm before any change of direction (unless otherwise specified by the appliance manufacturer). This is in accordance with the recommendations contained in BS 5440 Part 1 section 6.1.4
DIRECT CONNECTION APPLIANCE TO SYSTEM CHIMNEY
When connecting from the appliance directly to a system chimney, the appropriate appliance connector must be used and the joint between the appliance spigot and the appliance connector must be securely caulked and sealed with non asbestos rope (or suitable alternative) and fire cement on solid fuel appliances.
Where painted product is used on a high temperature application, then this must be a high temperature paint specification. See latest Schiedel ICID Plus catalogue for details of Schiedel High Temperature Paint spec.
DISTANCE TO COMBUSTIBLES
In accordance with building regulations, it is essential that the correct distance to combustible material is maintained. On solid fuel applications, using the G60 ventilated fire stop plates (round or square in combination with the G60 ventilated support plate, where there is a risk of soot fire, a distance of 60mm to combustibles must be maintained within a combustible floor and within a combustible shaft (see Fig.1 below).There is no need to line the area within the floor cavity with plasterboard; however the ventilated fire stop plate and ventilated support plate must be used.
On solid fuel applications using the G50 ventilated fire stop in combination with the G50 ventilated support plate, a distance of 50mm to combustibles must be maintained within a combustible floor and within a combustible shaft (see Fig 1 below). There is no need to line the area within the floor cavity with fire resistant board: however the ventilated fire stop plate and ventilated support plate must be used.
On gas and oil applications, a distance of 50mm to combustibles must be maintained within a combustible floor and within a combustible shaft. The ventilated fire stop plate and ventilated support plate must be used.
Where the chimney penetrates a non combustible floor and where a non combustible shaft is used, a distance of 50mm to the shaft is sufficient. In this case, non ventilated fire stop plates and support plates may be used with a ventilated fire stop being used where the chimney penetrates into the roof space.
On bungalow applications where the chimney runs through either a combustible or non-combustible ceiling, an unventilated bungalow fire stop plate kit can be used. Please note that an unventilated support plate can not be used above the ceiling in this case. The weight of the chimney should be supported using the roof support (see p.29). Distance to combustibles must be respected within the ceiling space (see Fig. 2 below) and mesh frame should be used within the loft space, which must be ventilated (see Fig. 2 below). Please note that trim collars are not to be used as an alternative to firestop plates. They are designed for use as decorative components only.
Internal house combustible floors
Internal bungalow (ventilated loft space) combustible and non-combustible floors
ENCLOSURE/SHAFTS
With the exception of the room containing the appliance, a mesh frame or alternative, which meets local Building Regulations, should be used where the chimney passes through any part of the building, where there is a risk of accidental human contact, i.e. a bedroom etc., or where there is a risk of contact with combustible materials stored in a cupboard or in the roof-space, the chimney must be enclosed in an appropriate way to meet Building Regulations. In all cases the minimum distance to any combustible material, including loft insulation, must be respected according to the table on p.2, and any enclosure should be ventilated using the appropriate ventilated fire stops (see p.22-23).
SUPPORT COMPONENTS
The weight of a chimney system is considerable and requires independent support. Minimal weight should be borne by the appliance. The weight of the chimney can be supported from floor level, or from the wall by using retrofit wall supports or wall support top plates together with side plates or cantilever brackets; or from first floor level by using a support plate and clamp fixed to the floor/ceiling joists.
Wall brackets are non load bearing and provide lateral support only. Refer to the load bearing tables on p.41 for full details of maximum loadings.
Where the flue is free-standing above the roof and its height exceeds 1.5m above the last support or above the roof, a height of up to 3m can be achieved unsupported using the extended locking bands at the joint immediately below the last support and on each pipe joint above the last support.
Alternatively guy wire brackets can be used at the 1.5m level and every 1.5m thereafter in conjunction with guy wires, or telescopic stays (see p.30 or rigid stays provided by others).
CHIMNEY TERMINATION
For full information relating to chimney termination, please refer to Annex M of
BS EN 15287-1. As a guide please refer to page p.38-39 of these installation instructions.
TERMINALS
All terminals must be secured with the use of a locking band. On solid fuel appliances, an open termination is normally recommended. However in certain conditions, rain caps or anti-downdraught terminals may be used.
Rain caps and anti-downdraught terminals are available in three versions, with anti-bird mesh, with spark guard, or without mesh. Where a terminal with mesh is used, there is a risk of soot build up, and therefore regular cleaning is required to avoid blockage, particularly when using oil or solid fuel.
JOINTING SYSTEM
All joints in the ICID Plus chimney range, which require a locking band, are made by means of a simple twist lock jointing method. This is achieved by pushing together the male and female collars on each end of the main chimney components and twisting the components through 1/6 of a turn to lock the collars into place.
It should be noted that the female collars on elbows and tees are not barbed in order to allow for these items to be positioned according to requirements on site. In all cases the joints should be held securely in place using the locking band, which is supplied with all components with a female collar.
STANDARD CHIMNEY SECTIONS (PIPES,TEES AND ELBOWS)
Before assembling chimney sections, loosen the locking band by lifting the clip. Push the interlocking collars together and twist into position (see Fig.1). Position the locking band so that it grips both collars then fasten using the clip.
Note:-joints must NOT occur within floor or ceiling spaces.
All flue gas carrying components must be installed with the direction arrow on the product label pointing to termination with the external male collar uppermost.
LOCKING BAND (SUPPLIED WITH EACH COMPONENT WITH A FEMALE COLLAR)
A locking band must be fitted to every joint in the system. The band is of stainless steel construction and is fitted with a quick release clip.
GASKET KITS
The standard single female lip seal kit is used to convert standard components with a male collar for use in condensing applications. The female lip seal must be fitted into the inward bead on the liner just below the male collar. Lubricant should be applied to the outside of the protruding liner of the next component to be fitted (see Fig.2 on page 12)
A separate gasket kit with 2 gaskets (1 female and 1 male) and a sachet of lubricant is required for adjustable pipes.
The female lip seal, with the lip on the inside is fitted, as per a standard component, into the inward bead as shown in Fig.2. The second male lip seal with the lip on the outside of the ring is fitted into the inward bead, which is situated in the top half of the 2-piece adjustable pipe (see Fig.3) and at the bottom of the 1-piece adjustable pipe.
N.B Where a 1-piece adjustable pipe is used, then no female lip seal is required in the groove below the male collar of the preceding pipe.
On 2-piece Adjustable Pipe a female lip seal is required on the preceding standard pipe to ensure leakage performance of the system. All lip seals to be added by installer.
On 1-Piece Adjustable Pipe no lip seal is required on preceding standard pipe, as a male lip seal (once added) will ensure leakage performance. All lip seals to be added by installer.
STRUCTURAL LOCKING BANDS
When installing the structural locking band on the ICID+ system, it is important to tighten the top bolt first followed by tightening the bottom bolt. Lastly, it is important to visually inspect the band and ensure that it is sitting straight on the joint. This sequence will ensure that the structural locking band is securely tightened against the ICID+ flue.
The structural locking band, which is purchased separately, is used instead of a standard locking band in a situation where extra structural support is required, for instance where the chimney height is >1.5m above the last support or above the roof. It is also used to provide extra support in long horizontal runs. A maximum of 3m unsupported height can be achieved by fitting the structural locking band on the joint immediately below and on every joint above the last support. Please see diagram on p.40.
STRUCTURAL LOCKING BAND FOR BENDS
The structural locking band for Bend, which is purchased separately, is used instead of a standard locking band in a situation where extra structural support is needed in an offset.

2. The stainless steel split band is then positioned around the chimney section and secured with the nuts and bolts provided to the back bracket.
3. The wall bracket provides lateral stability only, it is NOT load bearing and is to be positioned at maximum 4 metre centres.
STRUCTURAL WALL BAND EXTENSIONS
Available in 3 different sizes. Type W1 gives adjustment of between 55-100mm from the wall. L1 gives adjustment of between 100-250mm from the wall and L2 gives adjustment of between 100-440mm from the wall.
Once the position of the support has been determined, secure the back bracket to the wall with a method of fixing to ensure adequate attachment and support.
Fasten the structural wall band to the extension brackets using the nuts and bolts provided.
BASE SUPPORT PLATE WITH DRAIN
This component is used to support the chimney directly from the floor. It should be fastened securely to the floor using bolts or screws provided by others.
LOAD BEARING SUPPORTS
All wall supports and floor supports are designed to provide load bearing support for the chimney. They must be used in combination with the relevant lateral support components, wall bands, guy wire brackets or telescopic roof stays as appropriate. See p.40 for further information.
RETROFIT WALL SUPPORT
• Lower the clamp band over the pipe length with the joint facing the wall.
• On the joint, ensure that the spring washer is between the plain washer and the bolt head,
• Tighten the two fixing bolts on the clamp band using a torque wrench up to a minimum of 10 Nm (Newton-Meters).
• Attach the side brackets to the fixing bolts on the side of the band, but don’t tighten.
• Attach the side brackets to the wall using a method of fixing to ensure adequate attachment and support, i.e. shield anchors.
• Mark up the hole positions for the brackets on the wall.
• Fix the brackets to the bolts on the side of the clamp band using the locking nuts provided.
• For maximum height of chimney see load bearing details on p. 41.
ADJUSTABLE TOP PLATE
The wall support is designed to be used internally or externally to provide either initial or intermediate support for the vertical chimney. It is used in combination with side plates or with cantilever brackets. The turned down edge at the front of the plates is slotted to allow for the plate to slide along the cantilever brackets and give some positional adjustment. The female socket on the pipe attached to the underside of the plate should be pushed down onto the preceding pipe and the joint secured using the locking band provided. The top plate is then attached to the side plates or the cantilever brackets using the bolts provided through the fixing slots in the top plate (see Fig. 1). The bolts should then be tightened firmly.
For maximum height of chimney see load bearing details, please refer to tables and diagrams on pages 40-41.
SIDE PLATES/CANTILEVER BRACKETS
Once the position of the support has been established in relation to the chimney route, secure the side plates or cantilever brackets to the wall using expansion bolts to ensure adequate attachment and support (see Fig. 2).
G50 CEILING JOIST SUPPORT
The joist support can be used in 2 different ways:
Option 1 - where the chimney passes through a combustible ceiling into the roof space, and the weight of the chimney has to be taken at floor level. The ceiling joist support must be firmly fixed by using bolts or screws. For load bearing Data refer to tables 1 and 2 on page 41. (as per Ventilated Support Plate)
1. Frame a four sided level square opening within the joists using timber stringers where necessary to allow for the correct distance to combustibles from the outer wall of the chimney. This distance must be a minimum of 50mm on gas, oil and solid fuel applications (see Fig. 1 alongside - distance x).
2. Lower the chimney section through the opening in the floor, and secure to the next section of pipe.
3. Locate the two halves of the support plates around the chimney section, and secure to the joists using screws or bolts.
4. Remove the self-drilling screws which are fastened to the clamp band. Then fasten clamp band around the chimney section and position on top of the plate. Tighten using the nuts and bolts provided.
5. Using the holes in the clamp band as a guide, fasten the three self-drilling screws to the outer case of the ICID Plus system.
Note: Joints must NOT occur within the floor or ceiling joists.
Option 2 - Install as per option 1, but rather than use wooden stringers between the joists, use the ceiling joist support arms, which are fixed to the joists using the screws provided. The plate is then attached to the support arms using the nuts and bolts provided.
ROOF SUPPORT
The roof support is supplied as a kit complete with two side plates for fixing to the roof trusses, a band to give lateral support to the chimney as it passes through the roof, and 3 self tapping screws, which are secured to the chimney through the band to give a load bearing capacity. When the plates are installed above the roof trusses as in Fig.1 the maximum number of pipes, which may be suspended from the roof support is 6 x 1m pipes. When the plates are attached below the trusses as in Fig.2 the maximum number of pipes, which may be suspended is 4 x 1m pipes.
1. The band should be lowered down over the top of the ICID Plus pipe, and positioned so that the side plates are resting on top of the roof trusses as in Fig.1 or below the roof trusses in the case of Fig. 2. The recommended position is always as per Fig.1 where circumstances allow this solution.
2. The band should then be tightened using the nut and bolt provided.
3. Using the holes pre-drilled in the roof support band, drill 3mm holes in the outer case of the chimney section (drill bit should be set for a depth no greater than 10mm to avoid any damage to the liner of the chimney)
4. Use the self tapping screws provided to secure the clamp band to the outer casing of the chimney section.
GUY WIRE BRACKET
This component should be used to secure unsupported chimney sections above roof level. Guy wires or preferably, telescopic stays or rigid stays (supplied by others) must be fixed to the bracket and secured to suitable anchorage points to ensure that the chimney sections are stable. A maximum chimney height of 1.5 metres from the last support, or from the roof is permitted. Additional height requirements MUST be supported using guy wire brackets, with suitable guy wires or rigid stays or by using telescopic roof stays.
TELESCOPIC ROOF STAYS
The telescopic roof stay kit has been added to the range to allow for extra support on chimneys above roof level, where standard guy wires can not be fitted. The telescopic legs allow for height adjustment from 1.6m-2.5m
CEILING HANGER
This accessory is designed to support horizontal runs of the chimney from the roof or ceiling and offers adjustment from 130mm to 1115mm.
1. Once the position of the ceiling support has been determined, the section length of uni-rax channel must be securely fixed to the roof or the ceiling using a method of attachment to ensure adequate attachment and support.
2. All items are assembled as shown to attach the length of studding to the channel.
3. Attach the stud connector to the length of studding and connect the eye bolt to the connector.
4. Position the split band around the chimney section and secure to the eye bolt using the nut/bolt provided.
5. Maximum support spacing to be no more than 1.5 metres.
WALL SLEEVE (90˚ & 135˚ VARIANTS)
Wall sleeves must be used to protect the building where the chimney passes through a wall (see Fig. 2 & 3). The 90° version is supplied as a straight length whereas the 135° version is mitred at 45 degrees on one end. The sleeve should be cut down to the correct length on site to fit flush with the wall (see Fig. 1 & 2). The sleeve should be adequately weatherproofed, using a good quality building mastic and rope fibre.
TWO PIECE TRIM COLLAR (90˚ & 135˚ VARIANTS)
Two piece trim collars are fitted around the ICID Plus pipe where it protrudes through both the inside and the outside of the wall (see Fig. 1 & 2). They should be fastened to the wall using an adequate method of fixing. The trim collars should be adequately weatherproofed back to the wall and around the chimney, using a good quality building mastic or equivalent.
ANGLED FLASHING
Manufactured in sheet aluminium for use on pitched roofs. The base of the flashing should be nailed or screw fixed to the roof batons prior to tiling. The front edge of the flashing should be hooked to the underside of the batons to prevent lifting. This component should be sealed with the mastic sealant provided and MUST be used in conjunction with the storm collar supplied.
FLAT FLASHING
Manufactured in sheet aluminium for use on flat roofs the base of the flashing should be covered by the roofing felt and then sealed. This component should be sealed with the mastic sealant provided and MUST be used in conjunction with the storm collar supplied.
STORM COLLAR
The storm collar should be sealed to the outer casing of the flue immediately above the flashing with the mastic sealant provided.
UNIFLASH
This item, which is manufactured with a malleable base and a silicone cone is used to provide a water tight flashing around the chimney as it passes through a roof pitched between 0-45 degrees. The cone is marked with pipe diameter sizes.
1. Cut the cone to suit the correct diameter of chimney.
2. Slide the flashing down over the top of the pipe and then form the base to the shape of the roof surface.
3. Seal as required.
HEALTH & SAFETY INSTRUCTION
Many building products, including chimney elements are manufactured using natural raw materials which contain proportions of crystaline quartz. During the mechanical processing of products, such as cutting and drilling, quartz dust is released which can get into the lungs. With higher levels of exposure over longer periods this may result in damage to the lungs (silicosis) and as a consequence of the silicosis disease, to an increased risk of lung cancer.
THE FOLLOWING PROTECTIVE MEASURES ARE TO BE TAKEN
Protection measures are required when cutting and drilling. Wet-cutting or dust extraction should be used.
HAZARDS FOR PEOPLE AND THE ENVIRONMENT
Mineral wool insulation materials in this group of products can release fine fibres which may have carcinogenic effects in the lungs. If inhaled, fibres can get into the body and cause damage to health. Larger fibres or fragments of fibres can cause irritation (itching) of the skin, the upper airways and the eyes!
PROTECTION MEASURES AND SAFE PRACTICE
Avoid contact with the skin! After finishing work, rinse off dust with water and change your clothes. wash exposed areas of skin thoroughly with soap and if necessary use a skin care product!
NEW HOUSING AIRTIGHTNESS REQUIREMENTS
Schiedel provide an air tight sealing kit to prevent leakage where the chimney passes through vapour and/or wind barriers. This sealing kit is used in conjunction with our ICS50 System Chimney. The use of 50mm insulation ensures that the outer skin temperature on the chimney remains low enough for the EPDM kit to maintain its elasticity, and remain tight around the ICS50 product, ensuring the air tight joint. The kit is then fastened securely to the air tight membrane using the special tape supplied in the bag, together with the EPDM seal.
INSTALLATION
Schiedel airtight kits are tailored to meet the outer diameter of Schiedel’s twin wall insulated ICS50 System Chimney. The kit is pulled around the outer case of the ICS50 System Chimney and attached to the air tight membrane, using the special tape provided.
SEALING TAPE
The special tape used with the airtight kit is made from elastic PE film and acrylic adhesive. This combination means the tape is long-lasting and quick to fit (it sticks immediately). To make it as easy to use as possible, the tape comes with a paper liner which is removed prior to use.
N.B. Do not use tape on steel pipe, only to seal the joint between the EPDM seal and the vapour/wind barriers.
APPLICATION
The tape is used to attach the EPDM seal to the vapour and/or wind barriers. Schiedel Chimney Systems Ltd does not advise using the tape on rough surfaces, concrete, brick or bitumen-based materials. Surfaces must be clean, dry and grease-free before fitting.
TERMINALS
Terminals are supplied complete with a locking band. Once the terminal has been pushed into place, the adjustment bolt on the locking band clip should be tightened to ensure that the terminal is properly secured to the previous pipe.
OUTLET SITING
Flue terminations for solid fuel & oil are subject to EN15287-1 2007. Figures A and B illustrate recommendations for the most commonly encountered outlet terminations. Flue terminations for gas in domestic situations are governed by the BS5440-1 2008 Section 4.2. Figure C illustrates recommendations for the most common siting situations encountered. Adjacent taller structures may require increased height. The minimum flue projection through the roof is 600mm to the underside of the terminal.
OUTLET SITING FOR OIL APPLIANCES (<45KW)
OUTLET SITING FOR SOLID FUEL APPLIANCES (<50KW)
1.The weather surface is the building external surface, such as its roof, tiles or external walls.
2.A flat roof has a pitch less than I0°.
3.The clearance for A or B, as appropriate, will also apply.
4.A vertical flue fixed to an outside wall should be treated as equivalent to an inside flue emerging at the nearest edge of the roof.
TESTING AND COMMISSIONING PRIOR TO FIRST USE
A flue flow test (Smoke Test) must be performed as outlined in BS EN 15287-1. In addition to this, a draught measurement must also be taken and recorded to verify that the installed system fulfils the draft requirements specified by the appliance manufacturer for the specific appliance.
APPLIANCE OPERATION
Appliance slumbering must be avoided, and if the appliance has been run on low fire conditions for an extended period, then it is advisable to run the appliance at controlled high fire condition for a minimum period of at least 30 minutes afterwards. Prolonged slumbering of the appliance at all times is a contributing factor to a system chimney 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 at all times. If corrosion occurs due to slumbering, then the guarantee will be invalidated on the system.
MULTI-FUEL APPLICATIONS
Multi-Fuel refers to an appliance which may be used to burn either seasoned wood, or approved solid fuels. These fuels should not be mixed, as this increases the risk of deposits being built up in the liner.
MAINTENANCE
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. Chimney flue cleaning and inspection require the use of appropriate tooling – 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 flue way is clear of any blockages such as birds nests etc.
We would advise that monthly checks are carried out to ensure that there is no build up of any deposits in the flue way of the connecting flue pipe or system chimney.
PAINTED PRODUCTS
Painted products are relatively maintenance free however should the product require cleaning then please follow the guidelines below:
• Ensure the system has fully cooled down as the paint may have softened due to exposure to high temperatures and this will prevent unintended damage to the paintwork.
• Carefully remove any loose surface deposits with a wet sponge (taking care not to scratch the painted surface).
• Use a soft brush (non abrasive) or a lint free cloth and a diluted solution of a mild detergent, e.g., pH-neutral liquid hand dish-washing detergent in warm water (DO NOT use solvents or aggressive household cleaners) and wipe down.
To remove all remaining residues, finish off with a wipe down using a clean lint free cloth with fresh water.
FUEL STORAGE AND USAGE
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 www.hetas.co.uk.
The fuel used must be suitable for the appliance - please refer to manufacturer’s instructions.
NOTICE PLATE FOR ICID PLUS PRODUCT
The Notice plate should be marked up in indelible ink and securely fixed in an unobtrusive but obvious position within the building such as: Next to the electricity consumer unit. Next to the chimney installation described. Next to the water supply stop-cock.
