7BOXER combination boiler - Installation and ServicingGENERAL4. Where the lowest part of the terminal is fitted less than 2m(6'6") above a balcony, above ground or above a flat roof towhich people have access then the terminal MUST beprotected by a purpose designed guard.Terminals guards are available from boiler suppliers. Askfor Tower Flue Guard, Model K6. In case of difficulty seekadvice from:Grasslin (UK) Ltd.,Vale Rise, Tonbridge, Kent TN9 1TBTelephone No. 01732 359 888Ensure that the guard is fitted centrally.5. Where the terminal is fitted within 850mm (34") of a plasticor painted gutter or 450mm (18") of painted eaves then analuminium shield at least 750mm (30") long should befitted to the underside of the gutter or painted surface fittedcentrally above the flue.6. The air inlet/products outlet duct and the terminal of theboiler MUST NOT be closer than 25mm (1") to combustiblematerial. Detailed recommendations on the protection ofcombustible material are given in BS. 5440: Part 1, 2000.IMPORTANT. It is absolutely essential to ensure, in practice,that products of combustion discharging from the terminalcannot re-enter the building or any other adjacent buildingthrough ventilators, windows, doors, other sources of naturalair infiltration, or forced ventilation / air conditioning.If this should occur the appliance MUST be turned OFF,labelled as 'unsafe' until corrective action can be taken.TERMINALThe terminal assembly can be adapted to accommodatevarious wall thicknesses. Refer to Frame 9 - Unpacking.AIR SUPPLYDetailed recommendations for all supply are given in BS5440.2The following notes are for general guidance:1. It is NOT necessary to have a purpose-povided air vent in theroom or internal space in which the boiler is installed.2. If the boiler is to be installed in a cupboard or compartmentpermanent air vents are required (for cooling purposes) in thecupboard/comparment, at both high and low levels.The air vents must either comunicate with room/internal space,or be direct to outside air. The minimum efective areas of thepermanent air vents, required in the cupboard/compartment,are specified as follows and are related to maximum rated heatinput.3. Both air vents MUST communicate with the same room orinternal space or MUST be on the same wall to outside air.4. In siting the air vents care must be taken to avoid the freezingof pipework.GAS SUPPLYThe local gas supplier should be consulted, at the installationplanning stage, in order to establish the availability of anadequate supply of gas. An existing service pipe must NOT beused without prior consultation with the local gas supplier.The boiler MUST be installed on a gas supply with a governedmeter only.A gas meter can only be connected by the local gas supplier orby a registered CORGI engineer.An existing meter should be checked, preferably by the gassupplier, to ensure that the meter is adequate to deal with therate of gas supply required. A minimum working gas pressure of20 mbar should be available at the boiler inlet.Do not use pipes of a smaller size than the boiler inlet gasconnection.IMPORTANT.Installation pipes MUST be fitted in accordance with BS. 6891.Pipework from the meter to the boiler MUST be 22mm O.D.The complete installation MUST be tested for gas soundness andpurged as described in the above code.FLUE INSTALLATIONPluming may occur at the terminal, so where possible, terminalpositions where this could cause a nuisance should beavoided.The flue must be installed in accordance with therecommendations of BS. 5440: Part 1, 2000.The following notes are intended for general guidance:1. The boiler MUST be installed so that the terminal isexposed to external air.2. It is important that the position of the terminal allows thefree passage of air across it at all times.3. Minimum acceptable spacing from the terminal toobstructions and ventilation openings are specified inTable 3.Table 3 - Balanced flue terminal positionTerminal Position Minimum Spacing1. Directly below or alongside anopening window, air vent or otherventilation opening 300 mm (12")2. Below guttering, drain pipes or soilpipes 75 mm ( 3")3. Below eaves 200 mm ( 8")4. Below balconies or a car port roof 200 mm ( 8")5. From vertical drain pipes or soil pipes 150 mm ( 6")6. From internal or external corners 300 mm ( 12")7. Above adjacent ground, roof orbalcony level 300 mm (12")8. From a surface facing the terminal 600 mm (24")9. From a terminal facing a terminal 1200 mm (48")10. From an opening in a car port(e.g. door or window) into dwelling 1200 mm (48")11. Vertically from a terminal on thesame wall 1500 mm (60")12. Horizontally from a terminal on the wall 300 mm (12")Table 4BoxerC 24C 28Air from room/internal spacecm (in )2 2Air direct from outside265 (41)310 (48)133 (21)155 (24)cm (in )2 2
