They are wall mounted naturaldraught open flue appliances using a cast iron heatexchanger and are available in four outputs ranging (20,000-60,000 Btu/h).The boilers which are designed to provide domestic hotwater and/or central heating must be used on INDIRECT hotwater systems cast iron heat exchanger is suitable for use on openvented gravity hot water/ pumped central systems or fullypumped systems which may be sealed or open - Page 3 The following range of Potterton Myson system controls arealso available and further information will be provided Programmer EP2001, EP3001, EP4001, EP5001and Electronic Thermostat PET1 Thermostatic Radiator Cylinder Thermostat PTT2 or PTT100 Electronic Room Thermostat PRT2 or PRT100 Motorised Zone Valve MSV222 or MSV228 Motorised Diverter Valve MSV322 INSTALLATION DATA - Page 3 The installation of the boiler must be in accordance with thelatest relevant requirements of the Gas Safety (Installationand Use)

3 Regulations 1994, local building regulations, IEEW iring Regulations and the byelaws of the local recommendations are contained in the followingBritish Standard Codes of Practice:-BS6798. BS5440 Part Part 2. BS55449 Part , BS4814,BS6891 BUILDING WATER GAS PUBLICATION SAFETY (INSTALLATION AND USE) STANDARDS (SCOTLAND) DIMENSIONS - Page 3 Figure 1 boiler DIMENSIONS (mm)4 GENERAL ARRANGEMENT - Page 4 Figure 2 - GENERAL ARRANGEMENT5 SITE REQUIREMENTS - Page 5 These boilers are not suitable for external installation. Theappliance must not be installed in bathrooms, shower rooms,bedrooms, bed-sitting rooms, garages or rooms where highlyinflammable materials or vapours are likely to be in toilets or cloakrooms is not recommended but ispermitted, provided the combustion air is taken direct fromoutside.

4 Where installation of the boiler will be in an unusuallocation special procedures may be necessary and BS6798gives detailed guidance in this that the gas supply pipe and meter are large enoughfor this appliance and any others that may be run off thesame meter. Reference should be made to BS6891 boiler Mounting boiler must be mounted on a flat wall, which may be ofcombustible material and must be sufficiently robust to takethe weight of the boiler . It is recommended that any wallcovering behind the boiler that may discolour should beremoved before mounting the boiler . The requirements of thelocal authorities and the Building Regulations must beadhered NOTICE:TIMBER FRAMED HOUSESIf the appliance is to be fitted in a timber framed building, itshould be fitted in accordance with British Gas Publication Operational Procedures for Customer Service Part 19.

5 If inany doubt, advice should be sought from the local region ofBritish Around the BoilerThis appliance must at all times be fitted more than 100mm(4in) above floor following minimum clearances must be maintained afterinstallation for correct operation and servicing of the boiler :-610mm (2ft) at the front of the ( ) each side of the (4in) at the (4in) at the bottom where fitted above a workingsurface clearances to these may be required forinstallation and are left to the discretion of the Air and Ventilation RequirementsGeneral recommendations are given in BS5440 Part 2, andthe following notes are given as a general of Compartments containing Gas BoilersTHE 60C IS NOT SUITABLE FOR INSTALLATION IN other models there should be two permanent air vents,one at low level and one at high level.

6 Each opening,whether left free or furnished with a grille, must have aminimum effective area in accordance with Table 1 Level ofArea for air whether takenAir Ventfrom a Room or Outsidesq. must be at least 300mm (l2in) clearance between thegrille on the front of the boiler casing and any internalsurface of the cupboard to allow for adequate air foroperation of the draught details for installation of a boiler within acompartment are given in of rooms containing Gas ventilation of the room containing the boiler shall includeair for combustion and draught diverter dilution. This appliesalso when the boiler is sited in a compartment, unless the airvents are both direct from permanent air vent shall be provided in an outside wall ofthe building at either high or low REQUIREMENTS - Page 6 This opening may be:aDirectly into the room or space containing the boiler or,bVia a duct through the wall or roof of the room, (wheresuch a method is considered British Gas should beconsulted) or,cInto an adjacent room or space which has an internalpermanent air vent of the same size to the roomcontaining the boiler .

7 It is undesirable to ventilate via akitchen, bathroom or air vent should be sited as far as possible from anyextract fan to avoid short circuiting. To avoid the possibility offreezing water pipes, the vent should not be sited near minimum effective area of the permanent air vent mustbe:30C22 sq sq in40C39 sq sq in50C56 sq sq in60C74 sq sq inIf the room ( kitchen) from which air is drawn, has anextract fan fitted, then the opening size of the permanent airvent should take this into account to ensure that theoperation of the boiler flue is not adversely affected when theextract fan is running with all doors and windows should be checked in accordance with BS5440 Parts 1and and DuctsAny grille and/or duct should be so sited and of a type not tobecome easily blocked or flooded and should offer lowresistance to air 100mm (4in) internal diameter flue must be connected tothis appliance to evacuate the products of combustion fromthe boiler .

8 The flueconnecting socket on the boiler is designed to accept fluepipe to a fluepipe to BS715 is to be used an adaptor must be fittedto the boiler connecting should be made to The Building Regulations andBritish Standard 5440 Part 1. The following notes have beencompiled for your guidance:-aThe flue pipe should be at least 25mm from anycombustible material, or when passing through a wall,floor or roof, be separated from any combustiblematerial by a non-combustible sleeve enclosing an airspace of at least 25mm around the flue a flue should rise vertically to a termination pointwhich is unaffected by down draught or wind , for practical purposes, the flue should havethe shortest run possible; 90 bends should be terminal should be at least above roof edge leveland must be of a type acceptable to British possible there should be at least 600mm (2ft)of vertical flue from the boiler flue ; A split socket should be fitted in this runs should be avoided.

9 If a near horizontallength is unavoidable, it must be followed by at leasttwice that length of vertical possible internal stacks, lined if necessary,should be brick chimneys must be lined with a liner acceptableto British condensation is likely a means of draining mustbe an existing flue is being used, ensure that it has beenthoroughly swept before lining or connecting the SUPPLY - Page 7A 240 volts ~ 50Hz. single phase electricity supply fused at3A must be provided in accordance with the latest edition ofthe lEE wiring regulations and any other local regulationsthat may apply. The current rating of the wiring to the boilermust exceed 3 amperes and have a cross sectional area ofat least in accordance with BS6500 1990 Table method of connection to the electricity supply MUST facilitate complete isolation of the appliance, preferably bythe use of afused three pin plug and unswitched, shuttered socket outlet,both complying with the requirements of , connection may be made via a fused doublepole isolator having a contact seperation of 3mm in all polesand serving the appliance and system controls DATA - Page 7 boiler TypeB11 BsMaximum Working (l00ft)Minimum Working Head (Fully pumped systems)150mm (6in)Minimum Circulating Head (Gravity systems) (4ft)
