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. 16 ON; see fig. 2) 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 (see fig. 1);
•
undo the cap on the circulation pump to eliminate any eventual air locks (see fig. 3). Undo the valve on the heat exchanger
and then close it again as soon as water appears (see fig. 4); 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 (light no. 13; see
fig. 2), bring it back up to 1.5 bar (light no. 15 ON; see fig. 2)
and
close the tap on the filling loop;
•
switch on the electrical power supply to the boiler;
•
turn selector switch

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;
•
turn on a hot water tap briefly;
•
if any noises are heard, loosen the valve on the heat exchanger (see fig.4) and close it again as soon as water appears;
•
check there are no obstructions in the exhaust duct;
