7. ROUTINE SERVICING
7.1. Checks before servicing
Before servicing the boiler, always check the following:
• Check the entire flue system, including joints and the flue terminal. Be sure that all of the assembly is correct and there are no blockages
• Ensure that all connections and fittings are ok. In case of leaking, remake the joints or check the tightness of the fittings
• If necessary, refill, vent and re pressurise the system
• Check the expansion vessel charge (only when the system is empty)
• Check that the condensate drain pipe is connected and all joints are ok
7.2. Prepare for servicing (figs. 26 and 27)
These are the preliminary steps to boiler cleaning:
• Be sure that the boiler is isolated from power supply and that gas supply is off
• Unscrew the two screws holding the front panel. Lift it up and forwards to remove it
• Unlock the upper part of the control panel and rotate it forwards
• Unscrew the two screws holding the combustion chamber cover. Lift it up and forwards to remove it
• Disconnect the gas pipe from the mixer
• Disconnect the two electric connections from the fan
• Remove the ignition/detection electrode from the combustion chamber front panel, unscrewing the two screws
• Unscrew the four nuts holding the combustion chamber front panel, and remove the burner/panel/fan assembly
7.3. Boiler cleaning
• Remove any deposits from heat exchanger, using a suitable soft brush. Never use brushes with metallic bristles
• Check all combustion chamber insulation panels and gaskets. Replace any damaged panel or gasket
• Remove any deposit from the exchanger coils, by suction or spraying water onto the coils themselves. Before using water, ensure that any
electric component is suitably protected. Any water used to clean the coils will drain through the condensate trap
• Check the condition of the electrode and, if necessary, clean or replace it
• Open the condensate trap cap to remove any deposits. Note: before opening the cap, be sure that the released water can be contained
7.4. Reassemble the boiler
• Before reassembling the burner/panel/fan assembly, pour some water into the coils of the heat exchanger, to ensure the condensate trap is full
of water when operating the boiler
• Reassemble the burner/panel/fan assembly, using its four nuts, and check it is positioned correctly
• Reconnect the electrode, the electric fan connections and the gas pipe
• Test the tightness of the gas pipe connection
• Put the control panel to its original position, and reassemble the two front panels
• Operate the boiler to check everything works correctly
