Horizontally from a terminal on the wall 300 mm (12")GENERALGAS 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 is to be installed only on a gas supply with agoverned meter.A gas meter can only be connected by the local gas supplier orby a local regional contractor.Check that the appliance is suitable for the proposed gassupply. An existing meter should be checked, preferably by thegas supplier, to ensure that the meter is adequate to deal withthe rate of gas supply required. A minimum gas pressure of20 mbar MUST be available at the boiler inlet, with the boileroperating.Installation pipes MUST be fitted in accordance with BS. 6891.Pipework from the meter to the boiler MUST be of an adequatesize. Both 100 FF and 125 FF models should be piped in22mm minimum. The final metre may be run in 15mm if it isvisible.The complete installation MUST be tested for gas soundnessand purged as described in the above code.FLUE INSTALLATIONSome pluming may occur at the termination, so terminalpositions where this could cause a nuisance should beavoided.The flue must be installed in accordance with therecommendations of BS. 5440:1.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 3.4. 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. The minimumspacing in Table 3, Nos. 2,3, 4, 5 and 6 would be 75mm inorder to allow a terminal guard to be fitted.Terminals guards are available from boiler suppliers - askfor Tower Flue Guard, Model K1. In case of difficulty seekadvice from:Tower Flue Components Ltd.,Vale Rise, Tonbridge, Kent TN9 1TB (Model K1)Telephone No. 01732 351 555Ensure that the guard is fitted centrally.5. Where the terminal is fitted within 1000mm (39 1/2 ") of aplastic or painted gutter or 500mm (19 1/2 ") of paintedeaves then an aluminium shield at least 1000mm (39 1/2 ")long should be fitted to the underside of the gutter orpainted surface.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: 1990.7. Where it is essential that the terminal wall plate is fitted, i.e.wall thicknesses over 600mm (23 1/2 ") or with an inaccuratelycut hole, the minimum spacing in Table 3 - Nos. 2, 3, 4, 5 & 6- would be 60mm (2 1/2 ") in order to allow the terminal wallplate to be fitted.IMPORTANT.It is absolutely ESSENTIAL to ensure, in practice, that productsof combustion discharging from the terminal cannot re-enterthe building or any other adjacent building through ventilators,windows, doors, other sources of natural air infiltration orforced ventilation/air conditioning. If this should occur, theappliance MUST be turned OFF, labelled 'unsafe' andcorrective action taken.TERMINALWARNING.For top outlet installation (100 FF only) the flue terminal MUSTalways be in the horizontal position.The terminal assembly can be adapted to accommodatevarious wall thicknesses. Refer to Frames 7 & 36.AIR SUPPLYDetailed recommendations for air supply are given inBS.5440:2. The following notes are for general guidance:1. It is NOT necessary to have a purpose provided air vent inthe room or internal space in which the boiler is installed.2. If the boiler is to be installed in a cupboard or compartment,permanent air vents are required (for cooling purposes) inthe cupboard/compartment, at both high and low levels.The air vents must either communicate with room/internalspace, or be direct to outside air. The minimum effectiveareas of the permanent air vents, required in the cupboard/compartment, are specified as follows and are related tomaximum rated heat input.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 thefreezing of pipework.
