4 Design 4.1 General In order to design a chimney installation the following steps should be followed to achieve a safe chimney installation. Chimneys shall comply with national regulations and nationally accepted rules. 4.2 Data requirements 4.2.1 Sources of data and information The data and information specified in 4.2.2 to 4.2.6 shall be obtained and documented as appropriate. NOTE The sources can be:  heating appliance manufacturers catalogues and literature;  chimney manufacturers literature including installation instructions;  architects drawings or plans and/or site surveys;  local building rules. A possible source of typical or average data is in Annex A and in EN 13384-1. 4.2.2 Heating appliance information The information for the heating appliance(s) (see Annex B for an example) shall be obtained from the documentation of the heating appliance manufacturer or if not available, default values may be used (see EN 13384-1:2002, Annex B), but the source of the data shall be documented in the design (see 4.2.1). 4.2.3 Chimney product specification The following information about the chimney product specification shall be obtained (see 4.2.1):  identification and designation of the system chimney or of the components for custom built chimneys or for relining an existing chimney, see also Annex C, Annex D and Annex E;  design load or maximum allowed chimney height to be supported by lengths, fittings and supports;  mass of components;  manufacturer’s installation instruction;  additional information for chimney sizing (see EN 13384-1).

4.2.4 Building construction and chimney route information In order to allow the chimney route to be determined the relevant details of the building or support structure shall be obtained (see Figure F.1). If the chimney is to be supported by the building structure, the construction of the building and the materials used shall be capable of supporting the loads imposed upon it by the chimney. The fixings shall be compatible with the materials of construction of the building. This shall be checked before installing the chimney. A check list of information is given in Annex F. 4.2.5 Local conditions Environmental and topographical particulars of the site shall be obtained. 4.2.6 Combustion air supply Information on the size and position of apertures for combustion air supply into the room containing the heating appliance shall be obtained (possible sources of data are given in 4.2.1). 4.3 Design requirements 4.3.1 General The design of the chimney installation shall be detailed and documented. Manufacturers' product information may fulfil this requirement. The design should enable a chimney product manufacturer’s standard components to be used in carrying out the installation. Modification of components, e.g. producing openings or adjustments of length may only be undertaken in accordance with the manufacturer’s instructions. NOTE The finished chimney should have a designation in accordance with EN 1443 (see Annex C). The chimney products should be chosen so that the designation reflects the suitability of the chimney for the intended use. Annex E gives an example for the designation of a metal system chimney and Annex A gives an example of the general designation of a chimney according EN 1443. The finished chimney should have a chimney plate (see Annex G). 4.3.2 Designation The chimney and connecting flue pipe shall have designation classes appropriate to the heating appliance data as required in 4.2.2 and the building structure data as required in 4.2.4. The connecting flue pipe may have a designation different from that of the chimney i.e. where the heating appliance output results in a positive pressure in the connecting flue pipe. Each designation parameter shall be of a class at least equal to that required or shall be of a higher class according to the following sequence:  T600 > T450 > T400 > T300 > T250 > T200 > T160 > T140 > T120 > T100 > T080;  H > P > N;  Wx > Dx;  D3 > D2 > D1;  W3 > W2 > W1;  G > O;

is the temperature class; P
is the positive pressure class; N
is the negative pressure class; O
is without soot fire resistance; G
is with soot fire resistance; xx
is the distance to combustibles; and for corrosion class: W
is wet operating conditions; D
is dry operating conditions; 1 is for gas and kerosene with a sulphur content ≤ 50 mg/m3; 2 is for light oil / wood in open fires; 3 is for heavy oil / wood in closed stoves / coal and peat. 4.3.3 Determination of designation of the chimney and connecting flue pipe 4.3.3.1 General The chimney shall be assigned designations according to EN 1443 (see Annex C). 4.3.3.2 System chimney The designation of an installed system chimney shall be according to the product standard EN 13063-1 and EN 13063-2 for clay/ceramic products and EN 1858 for concrete products. The designation of an installed metal system chimney according to EN 1856-1 shall be according to Annex H. The designation of an installed plastic system chimney shall be according to the product standard EN 14471 excluding the location, reaction to fire and enclosure parameters. 4.3.3.3 Custom-built and relined chimney The designation of a custom-built or a relined chimney shall be determined. The methods to determine the designation is according to the calculations of Annex A or according to national regulations or nationally accepted rules. The temperature class, the sootfire class and the distance to combustible material given in the designation of a chimney product may be used for the custom-built chimney designation. NOTE Examples for the determination of the designation of relined and custom built chimneys are given in Annex I and Annex J.

EN 13063-1 and EN 14471 shall be determined according to 4.3.3.2. The designation of connecting flue pipes constructed in a custom-built manner, e.g. using glass, fibre products, or clay products such as bricks, should be determined according to Annex A. 4.3.4 Materials of construction 4.3.4.1 General Supplementary materials not supplied with the chimney products shall be fit for purpose (e.g. in terms of corrosion, temperature and strength), jointing compounds (e.g. cements, mortars and seals), rendering, waterproofing/sealing materials, fixings, screws or additional supports. 4.3.4.2 System chimneys System chimneys shall be in accordance with EN 1856-1, EN 1858, EN 13063-1, EN 13063-2 and EN 14471. 4.3.4.3 Relined chimneys 4.3.4.3.1 Flue liners Flue liners for relining shall be made from rigid flue liners according to the requirements of EN 1457,
EN 1856-2 and EN 1857, or flexible flue liners according to the requirements of EN 1856-2. Positive pressure and wet designated flue liners and fittings (i.e. access component), including any seals/sealants shall be confirmed as a combination for that pressure class and condensate resistance class. Chimney products according to the requirements of EN 1806, EN 1856-1, EN 1858 and EN 14471 may also be used as liners. 4.3.4.3.2 Insulation Any insulation between the new liner and the outer wall shall be either rigid or be loose material and be approved to be fit for the intended use or be an air gap or according to national regulations or nationally accepted rules. The thermal resistance or the thermal conductivity of the insulation shall be obtained from the product manufacturer, or in the absence of this information, typical values for the thermal conductivity are given in Annex A. NOTE 1
Care should be taken when using loose infill without binders to prevent the risk of flue blockage arising from the escape of the insulation into the flue, e.g. by choosing a material with adequate corrosion resistance and allows free movement of the flue liner. Loose infill with binders shall not prevent free movement of the liner. NOTE 2
To determine the effect of a closed air gap see Table A.3 or the alternative calculation. NOTE 3
To determine the effect of an open air gap an external heat transfer coefficient of 8 W/(m2⋅K) should be used in the calculation for heat transfer (see EN 13384-1). Any additional insulation outside of the air gap is excluded in the calculation.

Annex A. NOTE 1 Care should be taken when using loose infill without binders to prevent the risk of flue blockage arising from the escape of the insulation into the flue, e.g. by choosing a material with adequate corrosion resistance and allows free movement of the flue liner. Loose infill with binders shall not prevent free movement of the liner. NOTE 2 To determine the effect of a closed air gap see Table A.3 or the alternative calculation. NOTE 3 To determine the effect of an open air gap an external heat transfer coefficient of 8 W/(m2⋅K) should be used in the calculation for heat transfer (see EN 13384-1). Any additional insulation outside of the air gap is excluded in the calculation. 4.3.4.4.3 Outer wall Chimney products in accordance with EN 12446, EN 1806, EN 1858 and EN 13069 may be used as outer wall components. Other products may be used, e.g. brick, steel, concrete according to national regulations or nationally accepted rules. Performance characteristics for some products are given in Annex A. 4.3.4.5 Connecting flue pipe and adapters The material of the metal connecting flue pipe shall comply with EN 1856-2. System chimney components including adapters complying with EN 1856-1, or EN 14471 can also be used. Flexible flue liners complying with EN 1856-2 can also be used as connecting flue pipes where permitted in accordance with national regulations. Connecting flue pipes and adapters may also be constructed in a custom-built manner, e.g. using glass, fibre products, or even clay products such as bricks, according to national rules.

EN 13384-2 which takes into account the location of the chimney outlet and the effects of the outlets being in the pressure zone. The chimney outlet is considered to be in an adverse pressure zone if the chimney outlet position is less than 0,4 m above the ridge and the distance of a horizontal line from the chimney outlet to the intersection with the roof is less than 2,3 m, and the chimney outlet is situated:  on a roof with a slope of more than 40°, or  on a roof with a slope of more than 25° if the opening for combustion air and the top of the chimney are on different sides of the ridge and horizontal distance from the top to the ridge is more than 1,0 m. NOTE 1 A chimney can also be considered to be adversely affected by the proximity of adjacent obstructions e.g. buildings, trees, mountains. A chimney outlet within 15 m from adjacent structures which extends over a horizontal angle of 30° and their upper boundary raises more than 10° above the horizon as seen from the terminal outlet can be affected by wind turbulence. This can be overcome by an aerodynamic terminal. Other dimensions, e.g. the prohibited zone, are related to environmental issues and not the functioning capability of the chimney. NOTE 2 For other applications e.g. involving industrial heating plant or process venting, the determination of the chimney outlet position can require other criteria, such as calculations for the dispersal of combustion products related to nearby surroundings. 4.3.19 External parts 4.3.19.1 General The maximum allowed height of external parts of chimneys shall be subject to the following limiting conditions as specified in EN 13084-1:  horizontal distance between the building and the chimney outer wall not to exceed 1 m;  distance between the supports not to exceed 4 m;  distance above the last structural attachment not to exceed 3 m. 4.3.19.2 System chimneys The maximum height of external parts of system chimneys shall be in accordance with
the relevant product standards EN 1856-1, EN 1858, EN 13063-1, EN 13063-2, EN 13063-3 and
EN 14471. The spacing of supports and unsupported height declared by the manufacturer shall not be exceeded.
