STARTING UP THE BOILER FOR 1
st
TIME
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 calibrated;
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
Fill the heating system as follows, making sure that the gas cock is closed:
• open the tap on the filling loop and fill the system until a pressure of 1.5 bar has been
reached (light no. 7 fig.2) and then close the tap on the filling loop;
• make sure the cap on the auto air vent is slightly loose to allow air to escape from the
system (see fig. 3).
• 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 and then close the tap on the filling
loop;
• switch on the electrical power supply to the boiler;
• turn the selector switch to the WINTER 7 position (see fig.1), after a few seconds the
pump will come into action;
• 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;
• check the pressure in the system: if this has gone down, restore it until the pressure gauge shows 1.5 bar. Close the tap on
the filling loop once this operation is completed;
