C 15 SPV 24 MEFM RESET MOD GENERAL INSTRUCTIONS CONCERNING THE BOILER SAFETY This manual is part of the product and it has to be given to the user. Read this manual carefully and keep it carefully for a further application by the user and by the mounting and installing authorized personnel.
Domestic cold water pressure 0,2 - 8 bar Exhaust gases temperature at rated output 142,4°C Burned gases connection ( input- output) O 100 / O 60 Burned gases connection length Max 3 m Orientative values 150 l Maximum water content in the installation Maximum surface of the precinct 150 m²...
The fan The boiler is provided with a fan for scavenging. The flue system and the air supply (for the boiler with forced draft) is made of two concentric pipes connected to the outside of the room where the boiler is mounted. The exhaust gases/ water heat exchanger is monothermal, the domestic water is The exhaust gases/ water heat exchanger...
The command and control system of the boiler running performs: - the ignition and the protection when the flame is extinguished, provided by the electronic ignition; - the protection when the gas is switched off, provided by electro-valve; - the water pressure signalling in the boiler, provided by minimum pressure sensor; - the temperature signalling on the heating and DHW circuits, provided by the electronic board functions;...

MOUNTING-INSTALLATION INSTRUCTIONS The chapter addresses both to the qualified persons which contribute to the boiler installation and to the beneficiary which is concerned that the effected works to be done following the safety rules in operation of all the installations which contribute to the good running of the boiler.
MOUNTING-INSTALLATION INSTRUCTIONS You must not use the boiler empty or only partly filled with water. THE USE OF EMPTY OR PARTLY FILLED BOILER MAY LEADS TO EXPLOSION. The domestic cold water supply pipe of the DHW processing circuit remains permanently open (the closing of the net is made only by the valves from the discharge points) to allow the dilatation taking over from this circuit.
It`s forbbiden to install the boiler without earthing. THE COUPLING FOR SCAVENGING Without coupling to the chimney The scavenging is made through a pipe of 60 mm diameter, coaxial with the air inlet pipe of 100 mm diameter. The exhaust pipe is within the inlet one. The input-output coaxial flue system is delivered with the boiler.

Comfort: pressing this button, you select the comfort module(symbol 6 on) and the SW 4 set range of the domestic circuit may decrease. Press again to cancel it (symbol 6 off). Heating: Pressing the button once, the temperature preset by the heating is displayed;...
DHW module in case of monothermal boilers (symbol 7 on) Ignition demand in the DHW module takes priority of the heating module. The burner ignition takes place when a DHW demand appears; the boiler tries to supply hot water to the user at a preset temperature.
- insufficient pressure of the water in the hydraulic core circuit (irregularity) in case the pressure sensor measures an insufficient pressure of the water in the system, (<0,5 bar) the burner and the pump are deactivated and the flickering intermittent symbol Err E1 occurs on the display.
THE BOILER RUNNING The boiler running will be < without permanent control> provided automatically by the controllers installed on the boiler, and eventually by the environment devices (room thermostat). These devices must be set at the temperature corresponding to the controlled environment. the temperature setting on the heating circuit will be between 40-80º...
Additional facilities you may obtain: - Mounting an exterior temperature sensor, the boiler adjusts the heat carrier temperature depending on the temperature value from outside the building, the room wanted temperature and the heat leakage coefficient through the building walls. T.
Delivering to the user It is compulsory that the qualified personnel to instruct the user in great detail about the following aspects on boiler starting: The boiler starting and the shutting-down procedures, in safety conditions by checking the following elements: * the electric power supply respecting the polarity * gas supply * the central heating circuit supply and loading...
