1. Introduction Note: This boiler must be installedand serviced by a competent personin accordance with the Gas Safety(Installation and Use) Regulations1994. In the UK 'CORGI' RegisteredInstallers undertake the work to asafe and satisfactory standard.The TURBOmax is a fullyautomatic, wall mounted, room sealedcombination boiler for central heatingand domestic hot water. Domestic hotwater is supplied directly from theboiler, without requiring a coppercylinder, cold water tank, feed andexpansion tank or associatedpipework. Domestic hot water haspriority over central heating.The boiler has been designed for usewith a sealed central heating system,and comes fully tested and assembledwith a built-in circulating pump,bypass, expansion vessel and divertervalve.The TURBOmax carries the 'CE' Mark.This demonstrates that theboiler fulfils the essential requirementsof the Gas Appliance Directive(Directive 90/396/EEC) and the GasAppliances (Safety) Regulations 1992.The CE Mark also demonstrates thatthe appliance complies with therequirements of the ElectromagneticCompatibility Directive (Directive89/336/EEC) and the Low VoltageDirective (Directive 73/23/EEC).The TURBOmax range consists ofmodels with outputs for domestic hotwater of 24 and 28 kW. The boiler iseasily sited on any internal wall andcan be installed with either a horizontalor vertical RSF (Room Sealed Fanassisted) flue. Flue extensions andadditional bends and elbows areavailable for increased siting flexibility.(The boiler is not suitable for externalinstallation).If desired an inhibitor may be used inthe system. Guidance on the useof inhibitors is contained in theseinstructions.Natural Gas and LPG versions of theboiler are available.The boiler contains a domestic hotwater heat exchanger. The temperaturein the heat exchanger is limited by theboiler control system and it is notnecessary to install a scale reducer onthe cold mains inlet to the boiler.However, in exceptionally hard waterareas to prevent scale formation in theproperty hot water systempipework, a scale reducer may befitted.The TURBOmax has built-indiagnostic indicator lights whichilluminate in sequence, indicating theoperational status of the boiler. Thisfeature provides key information toaid commissioning and fault finding.The data badge is fitted on the bottomof the combustion chamber.See text of General Requirements forInstallation Requirements or notes.3
