Air in pipes Important: A central heating system can not operate correctly unless it is filled with water and air bled from the system. If these conditions are not met the system may be noisy. Bleed the air in the radiators and adjust the pressure if system requires. If the system requires filling to often this may be due to minor leaks or corrosion in the system. Gas installation If conversion from G20 to 30 or 31 is required, refer to section 13. It is recommended that any air is purged from the supply at the gas purge point on the gas valve, see diagram 12. 1. Filling the system The following steps 1 - 8, show how to fill the system. BURNER PRESSURE POINT GAS PURGE POINT 1. Make sure that: · The boiler is connected to the electrical supply. Turn the switch OFF ( 0 ) 11898 F24E shown 2. · Open the three water isolating valves. Diagram 12. 1 Note: Isolating valves are shown in the: OFF position HEATING RETURN F24E shown COLD WATER IN (F24E Only) HEATING FLOW DOMESTIC HOT WATER OUT (F24E Only) GAS SERVICE COCK 3. · Undo cap on automatic air vent on top of pump and leave undone. 9810 4. · Turn the switch ON ( I ) · F24E Only Open the tap on the filling device · Fill the system until the pressure indicated on the display is 1 bar. Close filling device. 9792 NOTE: On initial fill there may be a small discharge of water from the Reduced Pressure Zone valve 27 4000124050-2 9796 12 Commissioning 5. · Bleed each radiator to remove air, ensure all bleed screws are re-tightened. · If necessary repressurise the system, refer to procedure 4 Ins 061a Adjusting the Central heating output. The central heating output is factory preset to approx. If a different central heating output is required, proceed as follows: To gain access to potentiometer P3, unclip the control box, see diagram 11. 1. 10217 The potentiometer P3, is shown in diagram 12. 2, to adjust to the required heating output, insert a small flat edge screw driver into the arrowed slot in potentiometer P3, turn clockwise to adjust to the desired setting. Use a manometer to monitor the burner pressure.
