Page 16: Description Of Operation And Functions
GENERAL WARNINGS For each operating mode one or more symbols appear on the LCD display. In the event of a fault, the display will show a code whose meaning is summarised in the following table: Fault Code Failed ignition lock Safety thermostat intervention lock No water Air pressure switch (MCS)/flue gas thermostat (MC) - Page 17 GENERAL HEATING PUMP ANTI-LOCKING FUNCTION An anti-locking function activates the circulator for 30 seconds every 24 hours of inactivity. Following a power failure, the first anti-locking intervention occurs after 1 hour of inactivity. The function is active even when operation is locked and the selector is set to OFF.
- Page 18 GENERAL FAN AND AIR FLOW CHECK (MBS MODELS) If an ignition request is received, the system checks for the absence of air flow (contact open) of the flue gas pressure switch, and if the test is passed the fan is activated. When air flow is detected (contact closed) the ignition sequence is started.
- Page 19 GENERAL HEATING MODE WITH EXTERNAL SENSOR (OPTIONAL) Operation is the same as in normal heating mode with the difference that the delivery temperature is calculated in relation to the external temperature read by the sensor and the K factor. The K factor is set with the P3 and P4 buttons. HEATING TEMPERATURE INCREASE BUTTON HEATING TEMPERATURE DECREASE BUTTON External temperature (°C)
- Page 20 GENERAL OPERATION WITH REMOTE CONTROL (OPTIONAL) The boiler can be operated with a RC03.54 remote control. The RC03.54 remote control is an intelligent hourly programmer complete with ambient sensor suitable for adjustment and control of wall-mounted gas boilers for heating and production of sanitary hot water mainly for installation in residential buildings.

INSTALLATION PRODUCT RECEIPT The boiler is delivered packed in one protective cardboard box. The bag (A) inside the cardboard box contains the following material: - Installation and maintenance manual - User’s manual - System manual - Warranty certificate - Hydraulic test certificate - Exploded diagram of spare parts - Paper fitting template. -
Page 24: Hydraulic Connection
INSTALLATION HYDRAULIC CONNECTION After securing the support hooks, position the template so that it sits flush with the wall. Starting from the end unions previously fitted on the template, proceed with installation of all the pipes: system delivery, system return, cold water, hot water, and possibly also gas and electric line with ambient thermostat. -
Page 25: Installation
INSTALLATION INSTALLATION The boiler must be installed by qualified persons. The installation must be in conformity with the provisions of the law regarding evacuation of the combustion products in accordance with the REGULATIONS IN FORCE. The combustible gases must be evacuated through a pipe with a diameter not less than that on the boiler and it must be connected to a flue suited to the system capacity. -
Page 26: Turning On
INSTALLATION TURNING ON FILLING THE SYSTEM Slowly open the feed cock until the system reaches a pressure of 1.5 bar indicated on the hydrometer and then close it. Check that the cap on the automatic air escape valve positioned on the circulator is loosened, and repeatedly activate the circulator to release the air in the circuit. -
Page 27: Flue Gas Exhaust Connection
INSTALLATION FLUE GAS EXHAUST CONNECTION The boiler operates by combustion in a sealed chamber and therefore does not require any particular ventilation, and can also be housed in compartments, storerooms, technical spaces, etc. There are also various possibilities for exhaust of the combustion products and intake of air from the outside. - Page 28 Ø 87 mm Baffle NO Baffle Ø 82 mm (standard hole) Baffle for coaxial pipes Fit the baffle on the 60Ø aluminium stub pipe of the upper boiler flange.

Page 38: Operation With Different Types Of Gas
INSTALLATION OPERATION WITH DIFFERENT TYPES OF GAS The boiler is set up and adjusted at the factory to operate with G20 or G30/G31 as indicated on the technical data plate and the packaging. Should the boiler need to be used with a gas different from that for which it was set up at the factory, a specific kit must be installed to be ordered separately. - Page 39 INSTALLATION Adjusting the minimum pressure The gas pressure at the burner must be checked through the pressure outlet positioned on the gas valve outlet pipe using a water pressure gauge or a micro pressure gauge - Remove the protection cover (G). - Disconnect the power cable (12V) from the modulating coil. - Adjust the minimum pressure to the value indicated in the table below, screwing down (to increase) or unscrewing (to decrease) the adjusting screw (I).
