This boilermay be installed in any room. However if the boiler is beinginstalled in a room containing a bath or shower it must onlybe installed in zones 2 or 3. In GB this is the current I.E.E.WIRING REGULATIONS and BUILDING REGULATIONS. InIE reference should be made to the current edition of I.S.813“Domestic Gas Installations” and the current ETCI rules.If the boiler is to be installed in a timber frame building itshould be fitted in accordance with the current version of theInstitute of Gas Engineers document IGE/UP/7. If in doubtseek advice from local gas undertaking or the manufacturer.6.4 Minimum clearancesC CABDMinimum clearanceA 165 mm: Air/flue pipe, 60/100 mm diameter275 mm: Air/flue pipe, 80/125 mm diameterB 180 mm; optimum approx. 250 mmC 5 mm; optimum approx. 50 mmD 500 mm clearance in front of the heat generatorto enable easy access for maintenance work (thesame as a door opening).Can be reduced to 5 mm if fitted behind remov-able door / panel.The boiler and flue are suitable for installation onto andthrough combustible materials provided that:1. Minimum 5 mm clearance is maintained around thecircumference of the flue (air intake).2. The combustible surface and fixings are suitable forsupporting the load.3. The minimum clearances from the boiler case are main-tained.6.5 Compartment VentilationThe boilers are very high efficiency appliances.As a consequence the heat loss from the appliance casingduring operation is very low.Compartment ventilation is not required as the products areonly certified, and can only be fitted with a concentric fluesystem.6.6 Air/flue pipe6.6.1 RegulationDifferent flue outlet configurations can be carried out.– Consult the installation manual for air/flue gas systemsfor more information about the other possibilities andassociated accessories.Minimum fall44 mm/m– Standard flue terminal kits have an in-built fall back tothe boiler to drain the condensate. These can be fittedlevel between the appliance and the termination position.All other extended flues must have a fall of at least 44mm/m.The maximum length of the flue outlet is defined according toits type (for example C13).– Whatever the kind of flue system chosen, observe theminimum distances to position the flue terminals.– To install the flue, refer to the separate flue instructionsupplied with your appliance.– Explain these requirements to the user of the appliance.In GB the minimum acceptable siting dimensions for theterminal from obstructions, other terminals and ventilationopenings are shown in diagram overleaf.In IE the minimum distances for flue terminal positioningmust be those detailed in I.S. 813 “Domestic Gas Installa-tions”.The terminal must be exposed to the external air, allowingfree passage of air across it at all times.Being a condensing boiler some pluming may occur fromthe flue outlet. This should be taken into consideration whenselecting the position for the terminal.
