6GENERALMexico Super FF4100 & FF4125 - Installation & ServicingGAS 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.In IE refer to I.S. 813:2002. Pipework from the meter to theboiler MUST be of an adequate size. Both FF100 and FF125models should be piped in 22mm minimum. The final metremay be run in 15mm if it is visible.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 be avoided.The flue must be installed in accordance with therecommendations of BS.5440-1:2000. In IE refer toI.S.813:2002.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 in Table 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 TFC Flue Guard, Model K1. In case of difficulty seekadvice from:Grasslin (UK) Ltd., Tower House, Vale Rise, Tonbridge,Kent TN9 1TB.Tel: +44 (0) 1732 359 888. Fax: +44 (0) 1732 354 445www.tfc-group.co.ukEnsure that the guard is fitted centrally.5. 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.5440-1:2000. In IErefer to I.S. 813:2002.6. Where it is essential that the terminal wall plate is fitted,i.e. wall thicknesses over 600mm (23 1/2 ") or with aninaccurately cut hole, the minimum spacing in Table 3 -Nos. 2, 3, 4, 5 & 6 - would be 60mm (2 1/2 ") in order to allowthe terminal wall plate to be fitted.7. The flue assembly shall be so placed or shielded as toprevent ignition or damage to any part of any building.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 shouldoccur, the appliance MUST be turned OFF, labelled 'unsafe' andcorrective action taken.TERMINALWARNINGFor top outlet installation (FF100 only) the flue terminal MUSTalways be in the horizontal position.The terminal assembly can be adapted to accommodate variouswall thicknesses. Refer to Frames 7 & 36.AIR SUPPLYDetailed recommendations for air supply are given inBS.5440:2. In IE refer to I.S. 813:2002.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. Theair 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.Table 4 - High and low vent areasBoiler Air from room/internal Air direct fromspace cm 2 (in.2) outside cm2 (in.2 )High level Low level High level Low levelFF4100 354 (55) 354 (55) 177 (28) 177 (28)FF4125 438 (68) 438 (68) 219 (34) 219 (34)Table 3 - Balanced flue terminal positionTerminal Position Minimum Spacing1a.
