103 General requirementsInstructions for installation and servicing ecoMAX10The flue assembly shall be so placed or sheilded as toprevent ignition or damage to any pary of the building.Terminal position mmA Directly below an opening, above an opening orhorizontal to an opening, air brick, opening window, etc. 300B Below gutters, soil pipes or drain pipes 75C Below eaves 200D Below balconies 200E From vertical drain pipes and soil pipes 25F From internal or external corners 300G Above ground, roof or balcony 300H From a surface facing a terminal 600I From a terminal facing a terminal 1200K Vertically from a terminal on the same wall 1500L Horizontally from a terminal on the same wall 300M Distance from adjacent for vertical Flue 500Table 3.2 Terminal position for a fan assisted concentric flueNote!In addition, the terminal should not be nearerthan 150 mm to an opening in the building fabricformed for the purpose of accommodating abuilt–in element such as a window.BS 5440–1 It is recommended that the fanned flue termi-nal should be positioned as follows:a) at least 2m from an opening in the building directlyopposite, andb) so that the products of combustion are not directlydirected to discharge across a boundary.1) Dimensions B, C and D:These clearances may be reduced to 25 mm withoutaffecting the performance of the boiler. In order toensure that the condensate plume does not affectadjacent surfaces the terminal should be extended asshown in fig. 3.8.2) Dimension F:This clearance may be reduced to 25 mm withoutaffecting the performance of the boiler. However, inorder to ensure that the condensate plume does notaffect adjacent surfaces a clearance of 300 mm is preferred. For IE, recommendations are given in the cur-rent edition of IS 813.Fig. 3.53.8 Air supplyDetailed recommendations for air supply are given inBS 5440: Part 2.It is not necessary to have an air vent in the room orinternal space in which the boiler is installed.3.8.1 Cupboard or compartment ventilationThe boilers are very high efficiency appliances. As a con-sequence the heat loss from the appliance casing duringoperation is very low. Compartment ventilation is requi-red if the flue used in not concentric and air is suppliedfrom the room or compartment the boiler is installed in.3.9 Electrical supplyA 230 V, ~ 50 Hz single phase electricity supply fused to3 Amp. must be provided in accordance with the latestedition of BS7671 (IEE Wiring Regulations) and any otherlocal regulations that may apply. In IE reference shouldbe made to the current edition of the ETCI rules. Themethod of connection to the mains electricity supply mustprovide a means of completely isolating the boiler andits ancillary controls. Isolation is preferably by the use ofa fused three pin plug and unswitched shuttered socketoutlet, both complying with the requirements of BS 1363.Alternatively, a 3 Amp. fused doublepole switch with a 3mm contact separation on both poles may be used.This appliance must be earthed.3.10 Guide to system requirements3.10.1 Water circulation systemDetailed recommendations for the water circulationsystem are given in BS 6798 and BS 5449: Part 1 (forsmall bore and micro bore central heating systems).Pipework not forming part of the useful heating surfaceshould be insulated to help prevent heat loss and possi-ble freezing, particularly where pipes are run throughroof spaces and ventilated underfloor spaces. Drainingtaps must be located in accessible positions which per-mit the draining of the whole system including the boilerand the hot water system. Draining taps should be atleast 1/2 in. BSP nominal size and be in accordance withBS 2879. The boiler is suitable for use with minibore ormicrobore systems. Copper tubing to BS 2871: Part 1should be used for water carrying pipework. All capillaryjoints in all DHW pipework must be made with lead freesolder. Particularly where a new boiler is to be fitted toan existing system, it is good practice that the system isthoroughly cleansed.Attention!To prevent the formation of deposits and pre-vent serious damage to the appliance andsystem , cleansers must be used carefully andmust be completely removed by thoroughlyflushing the system. Cleansers should only beleft in systems for a maximum of 24 hours.balcony/eavesflue extended toclear any overhangflue adequatelysupportedgutter
