8.4 Boiler cleaning

The cleaning accessories are supplied as standard and placed inside the combustion chamber.
To carry out cleaning, proceed as follows (see Fig. 20 and Fig. 21):
• Open the front door (ref. 1) and remove the turbulators (ref. 2).
• Clean the inside of the combustion chamber and flueways using a brush (3 - not supplied) or other implements suitable for the purpose.
• Remove the accumulated deposits in the smoke box through the opening of the inspection doors (4). If necessary, remove the smoke
box closure (5), replacing the seal before assembly.
• Periodically check that condensate drain (6) is not obstructed.

8.5 Boiler operation check

Before igniting the boiler and carrying out the functional check, make sure:
• the turbulators are correctly positioned with the exchange tubes.
• The hydraulic and fuel circuit valves are open.
• There is enough fuel available.
• The expansion vessel is properly loaded.
• The hydraulic circuit pressure, when cold, is above 1 bar and below the boiler's maximum limit.
• The hydraulic circuits are vented.
• The electrical connections to the power supply and components (burner, pump, control panel, thermostats, etc.) have been carried out.
• The live-neutral connection must absolutely be respected; the ground connection is mandatory.
After carrying out the above operations, to start the boiler:
• If the system is equipped with a temperature controller or programmable thermostat(s), check that they are "active".
• Set the room programmable thermostat(s) or temperature control to the desired temperature.
• Turn the system main switch "On"
• Set the boiler thermostat on the control panel to "On" and check lighting up of the green indicator.
The boiler will carry out the ignition phase and keep working until the set temperatures are reached. In case of ignition or operation faults, the
boiler will do a "LOCKOUT" signaled by the red warning light on the burner and the red indicator on the control panel. After a "LOCKOUT"
wait about 30 seconds before restoring the startup conditions. To reset startup conditions, press the burner "button/indicator" and wait for
the flame to ignite. If this operation fails, it can be repeated 2-3 times, then check:
• The information provided in the burner instruction booklet.
• The section "BOILER OPERATION CHECK".
• The electrical connections on the diagram supplied with the control panel.
After startup, make sure the unit stops and then starts again:
• Changing the boiler thermostat setting.
• Operating the main switch on the control panel.
• Adjusting the room thermostat, timer programmer or temperature control.
• Checking the free and correct rotation of the circulating pumps.
• Checking complete boiler shutdown by operating the system main switch.
If all the conditions are met, restart the unit and check the combustion (smoke analysis), fuel flow rate and tightness of the door and smoke
chamber seals.
