STARTING UP THE BOILER
After connecting up the water supply, before starting up the boiler, carry out the following procedures:
Preliminary procedure
• Do as follows:
• make sure the power supply for the boiler is the same as that stated on the plate (230V - 50Hz) and that the live, neutral and earth
connections have been properly connected;
• make sure the type of gas being supplied is the same as the type for which the boiler has been tested and approved (see plate data);
• make sure the unit is properly earthed;
• make sure there are no flammable liquids or materials in the immediate vicinity of the boiler;
• make sure that any shut-off valves in the heating circuit are open;
• open the gas cock and check the gas seals, making sure the counter shows no sign of leaks; in any case, double check by using a soapy
solution and eliminate all eventual leaks. The checking procedure for the gas burner attachment is carried out with the boiler working;
• make sure the electrical mains switch is OFF;
• remove the front cover by pulling it forwards;
• undo the side screws and rotate the panel downwards
Filling the system
After making sure the gas cock is closed, fill the heating system as follows;
• fill the system until a pressure of 1.5 bar has been reached (light no. 11 ON; see fig. 1) and then close the tap on the filling loop;
• make sure the cap on the auto air vent valve is slightly loose to allow air to escape from the system;
• undo the cap on the circulation pump to eliminate any eventual air locks; it is a good idea to purge all radiators of air at this point too;
• before starting up the boiler the water pressure must be checked again; if this is seen to be below 0.5 bar, bring it back up to 1.5 bar (light
no. 11 ON; see fig. 1) and close the tap on the filling loop.
• set ON/OFF switch in ON position (fig.1), after a few seconds the pump will come into operation;
• once the boiler is working, if any noises are heard in the system, repeat the above air purging procedures until there is no air left in the
system;
• check there are no obstructions in the exhaust duct;
