Initial procedures
To guarantee safety and the correct operation of the appliance, the
boiler must be prepared for operation by a qualified technician who
possesses the skills which are required by law.
Filling the hydraulic circuit.
Proceed in the following manner:
- Open cold water inlet tap;
- Lift the cap on the automatic air relief valve on the circulation
pump;
- Gradually open the valve under the boiler
- Open each air release tap starting with the lowest point and close it only
when clear water, free of air, is visible.
-
Close the valve under the boiler when at least 1-1,5 bar registers on
the pressure gauge.
Gas supply
Proceed in the following manner:
- make sure that the main gas supply uses the same type of gas as
indicated on the boiler data plate;
- Open all doors and windows;
- Make sure there are no sparks or naked flames in the room;
- Make sure that the system does not leak fuel using a cut-off valve
inside the boiler itself which should be closed and then opened
while the gas valve is disabled. The meter must not show any signs
of gas being used for 10 minutes.
Electricity supply
- Check that the voltage and frequency of the electricity supply
correspond to the data shown on the boiler data plate;
- Make sure that the earthing connection is efficient
