Failure to install appliances correctly could lead toprosecution. It is in your own interest, and that of safety, toensure the law is complied with.The installation of the boiler MUST also be in accordance withthe latest l.E.E Wiring Regulations, local building regulations,bye-laws of the local water authority, the building regulationsand the Building Standards (Scotland) and any relevant requi-rements of the local authority.Detailed recommendations are contained in the followingBritish Standard Codes of Practice:BS. 6891 Low pressure installation pipes.BS. 6798 Installation of gas fired hot water boilers of ratedinput not exceeding 60 kW.BS. 5449 Forced circulation hot water systems.BS. 5546 Installation of gas hot water supplies fordomestic purposes (2nd Family Gases)BS. 6644 Ventilation (for gas appliances of rated inputexceeding 60 kW)BS. 5440:2 Ventilation (for gas appliances of rated input notexceeding 70 kW net.)BS. 5440:1 Flues (for gas appliances of rated input notexeeding 60 kW)BS. 4814 Specifications for expansion vesselsHealth & Safety document no 635The Electricity at Work Regulations, 1989Maximiser SE - Installation 2Maximiser SE boilers are fully automatically controlled, wallmounted, low water content, balanced flue, fanned superefficient condensing gas boiler.The Maximiser SE condensing boilers can be installed eitheron the wall or into a prefabricated floor mounted frame.The boilers are suitable for use with a room sealed flue oropen flued application.Through a sophisticated control system combined with premixburner arrangement the boilers are capable of high operatingefficiencies of 94% and low emissions.The heat exchanger is manufactured from extruded aluminiumfinned tubes sealed into aluminium end plates.Note. These boilers cannot be used on systems which includegravity circulation.The boilers are suitable for connection to fully pumped, openvented or sealed water systems. Adequate arrangements forcompletely draining the system by provision of drain cocksMUST be provided in the installation pipework.
