installation Connecting the Flue The boiler is designed to operate in B mode (by drawing air from the room) and in C mode (by drawing air from outside). When installing an exhaust system be careful when handling the seals, in order to avoid flue gas leaking into the air circuit. The horizontal kit must be tilted with a downward slope of 3% towards the boiler to evacuate the condensates. When type B installation is used, the room in which the coiler is installed must be ventilated using a suitable air inlet which complies with current legislation. In rooms where corrosive vapours may be present (for example, laundry rooms, hair studios, rooms where galvanic processes take place, etc.) it is important that type C installation is used, with air for combustion drawn from outside. In this way the boiler is protected from the effects of corrosion. When implementing coaxial suction/exhaust systems the use of authentic accessories is obligatory. The flue gas exhaust ducting must not be in contact with or placed near flammable materials, and must not cross building structures or walls made using flammable material. When replacing an old boiler, the ventilation and flue gas exhaust system must always be replaced. GENUS PREMIUM HP 45/65 is equipped for connection to a 80/125 coaxial flue gas suction and exhaust system. Mount the flue gas exhaust and air suction collector using the screws provided. Make sure that the seals are positioned correctly. A suitable adapter must be used when using split suction and exhaust systems. GENUS PREMIUM HP 85/100/115/150 is equipped for connection to a 100/110 twin-pipe flue gas suction and exhaust system, but is necessary to use the adapter. A suitable adapter must be used when using coaxial system. The flue gas exhaust ducting joint should be created using a male/ female coupling and a seal. Couplings should always be arranged so that they go against the direction of the condensate flow. Types of boiler - flue exhaust connection - coaxial connection of the boiler to the suction/exhaust ducting - split connection of the boiler to the exhaust ducting with air suction from outside For details relating to connection lengths and direction changes, please consult the “exhaust types” table. The suction/exhaust ducting connection kits are supplied separately from the appliance, according to different installation solutions. If there is any loss of pressure in the piping, please refer to the gas flue accessories catalogue. Supplementary resistance must be borne in mind during the sizing process mentioned above. For the calculation method, equivalent length values and installation examplesplease refer to the gas flue accessories catalogue. WARNING Make sure that the flue gas exhaust and ventilation ducting are not obstructed. Make sure that there are no leaks along the flue gas exhaust ducting. 17
