They are specially designed for use in central heating systems, but can also generate domestic hot water if connected to a suitable storage cylinder. 12 20 13 19 14 15 18 17 Novella boilers feature electronic ignition and ionisation flame detection. The control panel (fig. 3.1) houses all the controls needed to control the various functions of the boiler.

Subsequently, proceed as follows to start up the boiler whenever necessary. Once you have completed all the preparatory steps, proceed as follows to start up the boiler for the first time. -- Turn the boiler’s mains power switch ON (fig. 4.1) -- Set the room thermostat to the required temperature (~ 20°C) or, if the system has a timer or timer-thermostat, make sure that this is switched “On” and adjusted to the required temperature (~ 20°C) (fig. 4.2) 8 Fig. 4.1 Fig. 4.2 -- Adjust the boiler’s temperature control to the desired temperature (operation not necessary if the boiler has been equipped with a temperature controller) (fig. 4.3) Fig. 4.3 -- Switch the boiler on at the control panel switch and check that the green power indicator lights (fig. 4.4). Fig. 4.4 The boiler will now start up and the burner will remain lit until the set temperature is reached. If any ignition or functioning errors occur, the boiler enters “LOCK-OUT” and the red LED on the control panel comes on to indicate this (fig. 4.5). Fig. 4.5 Proceed as follows to reset the safety thermostat. -- Wait for about 1 minute, then press the "burner reset" button (fig. 4.6). -- Wait for the burner to complete the entire start-up cycle again, up to the ignition of the flame. Fig. 4.6 The boiler will also shut down if the flue gas thermostat trips. To reset the boiler in this case, remove the hood and reset the flue gas thermostat (fig. 4.7). bbIf the flue gas thermostat trips repeatedly, make sure that the flue gas pipes are not blocked and that the flue is properly constructed. Fig. 4.7 bbNovella boilers are equipped with a fac- tory-calibrated minimum pressure switch for the gas supply. This shuts down the boiler if the gas supply pressure is not sufficient to ensure correct functioning. Operation of this pressure switch is not signalled. 5 SHUT-DOWN If the boiler is not going to be used for an extended period of time, perform the following operations. -- Switch the boiler on at the control panel switch and check that the green power indicator lights (fig. 5.1). Fig. 5.1 -- Turn the mains power switch OFF (fig. 5.2). Fig. 5.2 -- Close the boiler’s fuel cock and water circuit cock (fig. 5.3). bbEmpty the boiler if there is any risk of Fig. 5.3 freezing 9 USER MANUAL 6 MAINTENANCE The only maintenance that the user can perform is the cleaning of the outside of the boiler casing with a cloth damped in soapy water. To remove stubborn marks, use a cloth damped in a 50% mix of water and denatured alcohol or a suitable cleaning product. Do not use abrasive cleaning pads or powder detergents. Never clean the boiler without first disconnecting it from the mains electricity supply by turning the mains power switch and the control panel switch OFF. Remember that safety legislation (in Italy, Presidential Decree 412 of the 26th August 1993) obliges the person responsible for the boiler to ensure that professionally qualified personnel perform periodic maintenance. The manufacturer’s Technical Assistance Service is qualified to satisfy all legal requirements and can also offer scheduled maintenance contracts. Stipulation of a maintenance contract guarantees: - greater savings - greater safety - greater comfort and peace of mind. On request, the manufacturer’s Technical Assistance Service will also provide you with a system service book. The Technical Assistance Service will also be pleased to instruct you how to get the best from your new boiler. 10 FIRST YEAR SECOND YEAR CHECK ALL SEALING COMPONENTS. • • CLEAN THE PRIMARY HEAT EXCHANGER ON THE FLUE GAS SIDE. • • CLEAN THE COMBUSTION CHAMBER, FAN AND VENTURI. • • CHECK THE WATER AND GAS SAFETY DEVICES. • • CHECK THE GAS FLOW RATE AND ADJUST IF NECESSARY. • • CHECK THE DRAUGHT OF THE FLUE. • • CLEAN THE BURNER AND CHECK THAT IT LIGHTS PROPERLY. • • CHECK THE FUNCTIONING OF THE WATER CIRCUIT. • • ANALYSE COMBUSTION GASES. - • CHECK AND LUBRICATE THE WATER CIRCUIT VALVE GROUP. - • CHECK THE TIGHTNESS OF THE GAS CIRCUIT. - • CLEAN THE HEAT EXCHANGER. - • CHECK THE EFFICIENCY OF ALL ELECTRICAL AND ELECTRONIC DEVICES. - • CHECK THE EFFICIENCY OF THE FAN. • • MAINTENANCE 7 OPTIONAL ACCESSORIES Wall-mounted weekly timer thermostat (fig. 7.1) (part number 1100279).
