17. Adjustments and settings (continued) CH anti cycling delay setting : If you would like to change the setting of CH anti cycling delay, if you want 3 min, proceed as follows: (NOTE : THE FACTORY SETTING IS 2 MIN 30 SECONDS AND THE FOLLOWING EXPLANATION REFER TO MENU 4 SECTION 8) Display 1 Switch to installer mode, press button and for 5 seconds, the display shows :10=0 if there is no default in the default register. 1 5 ” 2 Press 3 times on menu button to gain access to menu 4, the display shows : 40=0 or 40=1 2 x 3 or 3 Change to section 8 (CH anti cycling 3 delay), press on button 8 times, the display shows :48=2.5 (factory setting 2 min 30 seconds) 4 = menu 4 8 = section 8 2.5 = 2.5 min (2 min 30 seconds) x 8 4 Press the setting button one 4 time, the 3rd and 4th digits flash together, Then press the to change the CH anti cycling delay, the display shows : 48=3.0 press the setting button to confirm the value. The display stops flashing. Setting procedure is finished. To exit from setting mode, leave the boiler for approx. 1 minute then the PCB will switch back to user mode. After programming please close the front control panel cover P (Fig. 43 page 36) 42

SERVICING INSTRUCTIONS A To ensure efficient safe operation, it is recommended that the boiler is serviced annually by a competent person, refer to Section 20 (page 54) for the Servicing Schedule. Before starting any servicing work, ensure both the gas and electrical supplies to the boiler are isolated and the boiler is cool. Before and after servicing, a combustion analysis should be made via the flue sampling point. After servicing, preliminary electrical system checks must be carried out to ensure electrical safety (i.e. polarity, earth continuity, resistance to earth and short circuit). IMPORTANT! AFTER AN ANNUAL SERVICE, THE SERVICE INTERVAL RECORD (SECTION 25, PAGE 60) MUST BE COMPLETED. 18. Replacement of parts The life of individual components vary and they will need servicing or replacing as and when faults develop. The fault finding sequence chart in Section 19 will help to locate which component is the cause of any malfunction, and instructions for removal, inspection and replacement of the individual parts are given in the following pages. Fig. 44 18.1 To Gain General Access All testing and maintenance operations on the boiler require the control panel to be lowered. This will also require the removal of the casing. Fig. 45 18.1.1 Removing the front panel : 1. Remove the security screw and unlock the two case locking catches A (see Figs. 44 & 45); 2. Remove the front panel from the rest of the casing (see Fig. 46). 18.1.2 Lowering the control panel : 1. Remove the front panel; 2. Unlock the two clamps locking and pivot the electrical box downward (see Fig. 47). Fig. 46 Fig. 47 43
