16. THE BOILER START-UP
16.1 BEFORE THE START-UP
The first start-up is a very important operation on which the future effectiveness and reliability of the equipment
can depend. For this reason, it must be carried out by our own Official Technical Assistance Service.
Before the start-up, it is important to check that:
-
The installation is in accordance with this manual’s instructions and with the local regulations.
-
The installation is full of water and vented of air.
-
The static water pressure of the installation (when cold) is between 1 bar minimum and 4 bar maximum.
-
The water circulation pumps operate in the correct direction.
-
The water cut-off valves are open.
-
The gas type and pressure correspond to the ones indicated for that boiler (see the boiler identification
plate)
-
The gas valves are open, the air of the gas installation purged and there are no gas leaks.
-
The electric connections are correct (220/230 V, 50 Hz, single phase, earth) so that the boiler is electrically
supplied.
-
The controls are set so as to require heat from the system.
Instruments required for the start-up:
-
A manometer to check the combustion chamber pressure drop, the gas injectors pressure and the inlet gas
pressure. We recommend to use two digital manometers (or U-shaped manometers with water columns).
-
A flue electronic analyser to measure CO,

and the flues temperature.
-
Ammeter/electrical tester.
-
Ionisation electrode, ignition electrode, fuses, screws, nuts.
