WALL HUNG BOILERS<strong>ActivA</strong>TECHNICAL OPERATING FEATURESNEW MULTIPASS CONDENSING HEAT EXCHANGERThe <strong>ActivA</strong> boiler <strong>co</strong>ntains a host of advanced technical featuresincluding a specially developed microprocessor <strong>co</strong>ntrol ensuringefficient and reliable operation.• Full pre-mix burner with modulation <strong>co</strong>ntrol in both heatingand water modes , <strong>co</strong>nstantly matching output to demand.• Electronic flame ignition with adjustable re-ignition sequenceto prevent lock outs.• Anti-seize function automatically activating motorised<strong>co</strong>mponents (pump, diverter, fan) during periods of inoperationto prevent seizing.• Frost protection feature sensing low temperatures to preventfreezing.• Fault display alert in case of operation problems.• New ‘Hydroblock’ section featuring motorised diverter valve,flow /pressure sensor, magnetic water flow switch. Ensuringsafety and reliability.• Automatic built in by-pass to protect boiler during low flowrates (eg all radiator valves closed)• Electronic <strong>co</strong>ntrols to IP44 and radio disturbance protection.Specially developed for the <strong>ActivA</strong> range the new ‘multipass’<strong>co</strong>ndensing heat exchanger is <strong>co</strong>nstructed from severalsections, depending on boiler output, of die cast pressuremoulded aluminium.This high quality aluminium-silica alloy is chosen for its excellentheat transfer properties and resistance to <strong>co</strong>rrosion. The <strong>ActivA</strong>heat exchanger carries a FIVE YEAR warranty against failureduring normal operation.The flue gas is forced in a unidirectional path through numerousfinned channels, firstly upwards for maximum heat exchangeand then forced downwards to extract further usable heat.Condensation forms in this bottom section due to the lowertemperature of the flue gas and is <strong>co</strong>llected and drained throughthe siphon.Central heating water flows through the heat exchanger in a<strong>co</strong>unter direction for maximum efficiency. The many waterchannels provide a very low water resistance <strong>co</strong>mpared withother heat exchangers and a <strong>co</strong>nstant velocity can be maintainedto ensure further efficiency.Internal view of the main heat exchanger.Flue path in the single section


Technical featuresWALL HUNG BOILERSTECHNICAL INSTALLATION FEATURESAll isolation valves are supplied with pre-formed <strong>co</strong>pper tailsfor easy <strong>co</strong>nnection. The filling loop is also provided for simpleassembly to the valves saving further time.The pre-fixing kit allows for the system to be <strong>co</strong>nnected andtested prior to the boiler being fitted. Included in the box.A ‘stand –off’ bracket means pipework can be routed upwardsbehind the boiler when required. This is an optional extra.Combi models are provided pre-wired with 1.5 m of cable tominimise electrical work. Plug-in time <strong>co</strong>ntrols can be mountedeasily in the boiler fascia.All valves and pipework can be neatly <strong>co</strong>ncealed behind a whitepipe <strong>co</strong>ver which is available.
