High dust levels are usual only if the materialis broken.Normal handling should not cause discomfort, but follownormal good hygiene and wash your hands before eating,drinking or going to the lavatory.If you do suffer irritation to the eyes or severe irritation to theskin seek medical attention.The insulation is composed of non-combustible material.Electrical SupplyWARNING: This boiler must be earthed.All system components shall be of an approved type and shallbe connected in accordance with the current issue of BS7671and any applicable local regulations.External wiring must be correctly earthed, polarised and inaccordance with the relevant standards.In GB this is BS 6891.In IE this is the current edition of I.S.813 "Domestic gasinstallation".Connection of the boiler and system controls to the mainssupply must be through a common isolator and must be fusedat 3A, maximum. This method of connection must be by a fuseddouble pole isolating switch, with a minimum contact separationof 3mm on both poles. The switch should be readily accessibleand preferably adjacent to the appliance. It should supply theappliance only and be easily identifiable as so doing.Alternatively, an unswitched shuttered socket outlet and 3Afused 3 pin plug, both to the current issue of BS1363 may beused provided that they are not used in a room containing a bathor shower.Wiring to the boiler must be PVC 85 o C insulated cable, not lessthan 0.75mm 2 (24/0.20mm).Manual Handling GuidanceDuring the appliance installation it will be necessary to employcaution and assistance whilst lifting as the appliance exceedsthe recommended weight for a one man lift.In certain situations it may be required to use a mechanicalhandling aid.Take care to avoid trip hazards, slippery or wet surfaces.Heating System ControlsThe heating system must be controlled as described in therelevant part of the current issue of :Building Regulations, approved document L1, and the references:1) GIL 59, 2000: Central heating system specification (CheSS)and2) GPG 302, 2001: Controls for domestic central heating systemand hot water.

Call your <strong>Installation</strong>/Servicingcompany.Protection Against FreezingThe appliance has a built in frost protection programme as longas the electricity and gas are left switched on.This device operates the burner and system pump when thetemperature inside the boiler falls below 6 0 C.Any other exposed areas of the system should be protected bya separate frost thermostat.4000124050-24
Draining and FillingCaution: The boiler is installed as part of a sealed systemwhich must only be drained and filled by a competent person.If the mains electricity and gas are to be turned off for any longperiods during severe weather, it is recommended that thewhole system, including the boiler, refer to diagram 1, shouldbe drained to avoid the risk of freezing. Make sure that, if fitted,the immersion heater in the cylinder is switched off.If in doubt, consult your servicing company.F24E Only• If the boiler loses water: the pressure will be indicated, seediagram 1 (a) and the boiler ON indicator (b) will flash redindicating a fault. Fill the system by the filling device (c) at thebottom of the boiler until the pressure gauge reads 1.0 bar.A mains inlet pressure of 2.0 bar is required to reach a fillpressure of 1.0 bar.Reset boiler: refer to diagram 2, turn the On/Off switch to (0),wait for five seconds.

WIRING REGULATIONS andBUILDING REGULATIONS.In IE reference should be made to the current edition of I.S.813"Domestic Gas <strong>Installation</strong>s" and the current ETCI rules.The central heating and domestic hot water (F24E only)temperatures are user adjustable.F24E Only. Domestic hot water demand always has priorityover heating demand.The boiler is designed for use as part of a sealed water centralheating system with fully pumped circulation. The pump,expansion vessel and associated safety devices are all fittedwithin the boiler.The boiler can be installed against either an external wall or onan adjacent inside wall, that is, the flue system will pass directlyto the rear or to either side to the terminal fitted on the outsidewall face.These instructions should be carefully followed for the safe andeconomical use of your boiler. The 'User Controls and Lighting'section describes how to safely use the boiler.Note: The boiler serial number is marked on the data labelattached to the rear of the control box.AccessoriesA range of accessories are available.For further information contact your supplier.5 4000124050-2
