The provision of stored domestic hot water is possible by the addition of an indirect cylinder with 'S' or 'Y' plan controls. An automatic range-rating facility is incorporated in the boiler for the central heating system in conjunction with the electronic burner modulation. [. . . ] Inform the user of the location of all drain cocks and air vents. Explain how to turn the appliance off for both short and long periods and advise on the precautions necessary to prevent damage should the appliance be inoperative when freezing conditions may occur. Show the user the filling loop position its function and how to repressurise the system using the filling/inlet valve. Advise the user that, for continued safe and efficient operation, the appliance must be serviced by a competent person at least once a year. 7. 2 6. 14 6. 14. 1 7. 3 7. 4 6. 14. 2 6. 14. 3 6. 15 Hinge up the control fascia and secure using the two screws. (fig. 26) Disconnect filling loop, fit filling loop cap. Leave filling loop in a safe and accessible place. Supplementary Instructions for Fitting & Removing Optional Time Clock and for Wiring to External Controls. Section 10 Appendices A and B at the rear of this manual provides full instruction for fitting and wiring the optional built-in time switches and for wiring to external controls. 7. 5 7. 6 Fig. 26 Case Screws Case screws (one either side) 20 Linea 24 & 28 SECTION 8 8. 1 SERVICING INSTRUCTIONS 6. Gain general access as described in 8. 4. Lightly clean with a soft brush and inspect for damage. If during initial inspection any combustion irregularity was suspected, remove injectors and clean or replace (see 8. 7). Place cloth below combustion chamber to catch debris. Clean heat exchanger using suitable brushes and rods if necessary. The insulating material is easily damaged. If any panels are damaged these should be replaced (see 8. 11). Replace all parts in reverse order but leave the controls fascia open and outer casing off. 11. Undertake a complete commissioning check as detailed in section 6. 12. Close up control fascia and refix front casing. 13. Clean off casing using soft cloth and dilute detergent. 14. Complete details of service undertaken in the boiler log book. NOTE: there is a flue gas analysis test point incorporated in the flue outlet. [. . . ] Switch on the electricity supply, the boiler will now light at the minimum setting. When low flame is established the pressure reading should be : 24 5. 1mbar (Plus or minus 0. 5mbar) 28 4. 3mbar (Plus or minus 0. 43mbar) If it is different adjustment should be made in accordance with the instructions in 8. 23. 11. 11 If the reading is incorrect it should be adjusted as follows: Identify the minimum adjustment potentiometer on the PCB (fig. With the boiler still in central heating mode and the burner at the minimum rate, using a small screwdriver turn the potentiometer clockwise to increase & anti-clockwise to decrease the gas pressure.
