General Data 1.5 B.S.I. Certification To facilitate minimum clearances it may be necessary to modify the kitchen units or fixtures, depending upon which type of connections are used. This boiler is certificated by B.S.I. for safety and performance. It is, therefore, important that no alteration is made to the boiler, without permission, in writing, from Hepworth Heating Ltd. A front access clearance should be provided as shown in diagram 1.5. Any alteration not approved by Hepworth Heating Ltd.
1 General Data 0906 A special top casing, part No. 424820, can be purchased to enable the boiler casings to be arranged flush with 600mm (235/8in) deep work tops and kitchen units. Where the installation of the boiler will be in an unusual location, special procedures are necessary, the current issue of BS6798 gives guidance on this. BOILER 700 A compartment used to enclose the boiler must be designed and constructed specifically for this purpose.
2 Water Systems 2.6 Cylinder 1370 FLOW RATE (GALLON/MINUTE) 0 1 2 3 4 5 6 7 8 9 10 For all systems supplying domestic hot water the cylinder must be indirect and to the appropriate British Standard. WATER PRESSURE LOSS (metre HEAD OF WATER) 2.7 Safety Valve A safety valve need not be fitted to an open vented system. 2.8 Draining Tap A drain tap must be provided at the lowest points of the system which will allow the entire system, including the boiler and domestic hot water cylinder to be drained.
3 Flue and Ventilation 1112 3.7 Cupboard/Compartment Ventilation Where the boiler is fitted in a cupboard or compartment, the high and low level permanent air vents must have effective areas in accordance with the Compartment Air Vent Table. C A B,C B,C Both the high level and the low level air vents must communicate with the same room, or must both be on the same wall to outside air. G A F G K A L K F F E K L G G G Under Car Port etc.
4 Installation Domestic gravity return, any one of the three remaining lower connections may be used for the gravity domestic hot water return. 0888 UPPER CASING BRACKET Fit plugs into all unused connections. NOTE, if only limited clearance is available it is recommended that the front tappings are used. 4.4 Planning Water Connections - Fully Pumped Systems CAPTIVE No.8 SCREW (8) NUT It is important that all connections are made as shown in diagram 4.4.
When using a rear tapping with Rc1 (1inch BSP) fittings for 28mm o.d. pipework it is recommended that a short nipple and a R thread (BSP) copper elbow is used. If the pipework is required to run back to the wall make sure that it will clear the boiler air duct and, if working to minimum clearance does not stick out too far from the boiler, see diagram 4.8. ALTERNATIVE FLOW (Must be adjacent to THERMOSTAT PHIAL POCKET) Make the water connections to the system pipework.

For overhanging top casing, fit four plastic pegs into holes “B”.
6.1 Control Box Cable Connection. WARNING. This boiler must be earthed. COVER Remove the screw and cover from the mains inlet connector, supplied loose, see diagram 6.1. Using heat resistant flexible cable of a suitable length and rating as stated in Section 1.7 “Electrical” connect the three wires to the appropriate terminals in the connector. L N E Engage slots and lugs, replace cover and secure with screw.
7 Commissioning Please ensure the “Benchmark” logbook is completed and left with the user. control knob “A” fully pushed in for about 15 seconds. If the pilot burner fails to stay alight, repeat the lighting procedure only now keep the control knob pushed for a little longer. 7.1 Preliminaries If the gas control knob “A” is turned to' 'a safety lock prevents it being turned on again until 3 minutes have elapsed.
7.3 Operational Checks 13 (1/2 in.) SPARK GAP APPROX. DIMENSION FLAME DIMENSION Check operation of the flame failure device as follows, with the main burner alight, turn the gas valve control knob “A” fully clockwise to its stop' ' , this will extinguish the main and pilot burners. The safety device should close before 60 seconds have elapsed, a click from the gas valve will indicate it has closed. 3-4mm. (1/8 in.
8 Servicing It is the law that servicing must be carried out by a competent person. Before commencing any servicing, turn off the gas supply at the gas service cock, see diagram 8.1 and isolate the electrical supply to the boiler. Always test for gas soundness after completing any servicing or replacement of parts. 9012 GAS SERVICE COCK (turn off) (shown closed) 8.1 Gain Access to the Boiler Pull the door forward at the top to disengage studs and lift to release from the slots, see diagram 7.3.
8 Servicing Check the condition of the insulation panels in the combustion chamber, renew if necessary. Check the condition of the seals on the cleaning door and the combustion chamber cover, renewing if necessary. 6040 8.5 Re-assembly Make sure that the baffle tray is replaced and secured with the graphite coated nuts, previously removed. SECURING NUT Make sure flueway baffles are positioned as diagram 8.6 BURNER 8.
9 Replacement of Parts Remove the nut retaining the spark electrode and remove. 9013 PILOT TUBE NUT Remove the two screws and nuts securing the pilot burner and shield to the combustion chamber cover. GAS VALVE PLUG Hook pilot injector over pilot tube olive when refitting. Check that the pilot flame length is as shown in diagram 7.2. Replace thermostat phial as Section 8.5. 9.5 Spark Electrode Gain access to the boiler as Section 8.1.
9 Replacement of Parts Disconnect the lead at the spark electrode, see diagram 9.2. Disconnect the gas valve plug from the valve, see diagram 9.1. When reconnecting lead make sure that the clear end is fitted to the spark electrode. Release the control box by removing the securing screw located at the top of control box and unhooking at the bottom, see diagram 9.4. 9.10 Electrical Control Box Pull the ignition lead off piezo unit, see diagram 9.4. Gain access to the boiler as Section 8.1.
10.1 Electrical L IMPORTANT, the preliminary electrical system checks as contained in the British Gas Multimeter Instruction book or similar publication, are the first checks to be carried out during a fault-finding procedure. On completion of the service fault-finding task which has required the breaking and remaking of electrical connections then checks, earth continuity, polarity and resistance to earth must be repeated.
6042 10 Fault Finding - Thermocouple Disconnect appliance thermocouple from the multifunctional control. Check that all connections are clean and in good condition. Fit test meter interrupter into the magnet unit. Fit appliance thermocouple into the test meter interrupter. Hold down control tap in ignition position. Ignite burner, allowing thermocouple to attain operating temperature. Measure the OPEN CIRCUIT voltage. Is voltage greater than 15mV? NO Faulty thermocouple. Replace.
10 Fault Finding - Pilot 0905 PILOT WILL NOT LIGHT START HERE Does pilot stay alight when gas valve knob is released? Check gas line-open all cocks, rectify any blockages, purge out any air. Does pilot light? NO NO YES Apply match to pilot burner instead of pressing piezo unit button. Does pilot light? NO PILOT SATISFACTORY YES Undo tubing nut at pilot burner. Turn gas valve knob to Pilot/Ign. Press gas valve knob.
