approved output range of the boiler. After havingopened the fuel on-off cocks and checked thatthere are no leaks in the supply line, place allthe switches on the ON position. The burner willthus be ready for first ignition and for the adjustmentsto be made by the authorised technician.On first ignition, check that the door, the burnerflange and the connections to the chimney aretight and that there is a slight negative pressureat the base of the flue. The fuel rate must correspondto the boiler's rated data and under nocircumstances must exceed the maximum outputvalue declared. The temperature of the fluegas must never fall below 160°C.8.3 Shutting down the boiler- Set the temperature controller to the minimum.- Disconnect power from the burner and closethe fuel supply.- Let the pumps operate until they are stoppedby the temperature controller.- Disconnect power from the electrical panel.9. MAINTENANCE9.1 General instructionsPeriodical maintenance is essential for thesafety, efficiency and long life of the appliance.All the operations must be carried out by qualifiedpersonnel. All cleaning and maintenance operationsmust be performed after having closed thefuel supply and disconnected the power supply.For the correct operation and maximum efficiencyof the boiler, the combustion chamber, fire tubesand smokebox must be cleaned regularly.9.2 Routine maintenanceThe interval between cleaning operations mustbe established by the user based on the experienceacquired on each individual system, consequentlythe maintenance intervals cannot beestablished in advance.In any case, the following minimum intervals arerecommended, according to the fuel used:- Gas: once a year- Oil: twice a year- Fuel oil: every 300 hours of operationIn any case, any local maintenance standards inforce should be observed. During the routinemaintenance operations, after having removedthe turbulators, brush the tube bundle and thefurnace. Remove the deposits accumulated inthe smokebox by opening the inspection doors.For more intense cleaning, remove the rearsmokebox and, if deteriorated, replace the fluegas seal. Check that the condensate drain is notblocked. Ensure that the control and measurementdevices serving the boiler are working correctly.Measure the amount of top-up wateradded, and after having analysed the water, adddescaler. The calcium and magnesium salts dissolvedin the water will, after repeated refills,cause deposits in the boiler and the overheatingof the metal plate, with possible damage that isnot attributable to materials or workmanship,and consequently not covered by the warranty.After having completed the maintenance andcleaning operations and started the boiler again,check the tightness of the door and the smokebox,and in the event of gas leaks, replace thecorresponding gaskets.The operations carried out must be enteredin the system logbook.9.3 Special maintenanceSpecial maintenance to be performed at the endof the season or for extended shutdowns.All the operations described in the previouschapter must be completed, plus the followingadditional operations:- Check the condition of the turbulators for wear.- After cleaning the flue gas circuit, wipe with arag dipped in a diluted solution of caustic soda.After having left to dry, wipe all the surfaceswith a rag dipped in oil.- Hygroscopic substances (quicklime, silica gelin small containers) should be placed insidethe furnace, which must then be closed hermeticallyso that air cannot enter.- Do not empty the system and the boiler.- Protect the screws, nuts and pins on the doorwith graphite grease.The operations carried out must be enteredin the system logbook.9.4 Cleaning the boiler (Fig. 19)To clean the boiler, proceed as follows:- Open the front door (1) and remove the turbulators(2).- Clean the inside surfaces of the combustionchamber and the flue gas path using a brush(3) or other suitable implements.- Remove the deposits accumulated in thesmokebox by opening the inspection door (4).For more intense cleaning, remove the smokeboxcover (5) and replace the gasket beforereassembling.- Periodically check that the condensate drain(6) is not blocked.9.5 Checking the operation of the boilerBefore staring and running the functional testson the boiler, make sure that:- The turbulators are positioned against theexchanger tubes.- The cocks in the water circuit and on the fuellines are open.- Fuel is available.- The expansion vessel is suitably filled.- The pressure of the water circuit, when cold, ismore than 1 bar and less than the maximumlimit allowed for the boiler.- The water circuits have been vented.- The electrical connections to the mains powerand the components (burner, pump, controlpanel, thermostats etc.) have been completed.- The phase-neutral connection must be observed,and the earth must be connected.After having performed the operations describedabove, the following operations are necessary tostart the boiler:- If the system is fitted with a temperature controlleror timer-thermostat, check that theseare “on”.- Set the room timer-thermostat or the temperaturecontroller to the desired temperature.- Move the main system switch to “on”- Set the boiler thermostat located on thecontrol panel- Move the main switch on the control panel to“on” and check that the green indicator lightcomes on.The boiler will run the ignition phase and willremain on until the set temperature has beenreached. If problems occur during ignition oroperation, the boiler will “LOCKOUT”, as signalledby the red light on the burner and the redindicator on the control panel. After a“LOCKOUT”, wait around 30 seconds beforerestoring the ignition conditions. To restore theignition conditions, press the burner“button/light” and wait for the flame to ignite. Ifthis operation fails, it can be repeated a maximum2-3 times, then check:- The information provided in the burner instructionbooklet.- The chapter on “CHECKING THE OPERA-TION OF THE BOILER”.- The electrical connections described on thediagram supplied with the control panel.When the boiler has started, check that it stopsand starts again:- Adjust the setting of the boiler thermostat.- Move the main switch on the control panel.- Set the room thermostat, the timer or the temperaturecontroller.- Check that the pumps are not blocked androtate in the correct direction.- Check the total shutdown of the boiler usingthe main system switch.If all the conditions are correct, restart theappliance, check the combustion (flue gasanalysis), the fuel rate and the tightness of thegaskets on the door and the smokebox.9.6 Checking the operation of the burner- Refer to the burner instruction manual.- Follow all the local legislation in force onburner maintenance.9.7 TroubleshootingThe following is a list with information on themain faults or problems that may occur duringthe operation of the boiler, showing the possiblecauses and corresponding solutions.- 22 -
