[. . . ] - TELEPHONE (0113) 252 7007 ELECTRONIC IGNITION - AUTOMATIC MODULATING BOILER. FOR CENTRAL HEATING AND DOMESTIC HOT WATER This new high efficient turbo-modulating boiler is designed to meet domestic hot water and central heating requirements at super high efficiency, unheard of only a few years ago. POSITION The appliance is extremely versatile as it can be fitted in almost any room. The appliance is room sealed, there is no contact between combustion chamber and living accomodation. [. . . ] Do not overtighten and use another spanner as a counter force to avoid straining internal connections. 46) Before any central heating connections are made to the boiler all system valves should be opened and the system thoroughly flushed out with cold water. - Connect the central heating return pipe to the isolating cock marked CHR. - Connect the central heating flow pipe to the isolating cock marked CHF. - Pipe dimension's and position are marked on template supplied and Fig. 46) The domestic hot water circuit does not need a safety valve but it is essential to ensure that the pressure of the cold water supply does not exceed 10 bar. If in doubt it is advisable to install a pressure reducing valve. The minimum pressure needed to operate the domestic hot water system is 0. 5 bar Fig. 44 5. 92 5. 10 5. 10. 1 5. 11 5. 11. 1 Fig. 45 with a flow of approx 3 Lts per min. The regulator screw on the cold water outlet of the diverter valve may be adjusted to prevent excess volume flow (Fig. 48 DlAGNOSTIC INFORMATION COMPUTER CONNECTION 6. 1 Each boiler has been through a rigorous operational procedure at our factory and should not require any further adjustment. If in the unlikely event of the appliance not operating correctly, please turn to the Fault Finding and Logic Sequence charts. GAS SUPPLY INSTALLATION Inspect the entire installation including the gas meter, test for soundness and purge, all as described in BS 6891. 6. 5 ELECTRICAL INSTALLATION Preliminary electrical system checks to ensure electrical safety shall be carried out by a competent person (earth continuity, polarity, resistance to earth). Those checks are outlined in the <<Instructions for British Gas Multimeter>> Booklet. If a fault has occurred on the appliance the fault finding procedure should be followed as specified under the servicing section of this document. INITIAL FILLING OF THE SYSTEM Open central heating flow and return valves. Unscrew the cap on automatic air release valve one full turn (leave open permanently). - Close all air release taps on the central heating system. 6. 2 6. 2. 1 - Gradually open stopcock at the filling point connection to the central heating system until water is heard to flow. - Starting with the lowest radiator open each air release tap in turn. Close it only when clear water, free of bubbles, flows out. [. . . ] TO REMOVE/REPLACE THE PRESSURE RELIEF VALVE (Fig. 5. 4. 2) from the outer casing, lower the instrument panel (sect. 7. 31. 6 Close the on/off valves for the heating system and drain the water from the drain point (Fig. 7. 32 Unscrew the screw from its body, clean or replace.
