28 Hydraulic test
After assembling the boiler body, the installer must carry out a water tightness test at a pressure equal to 1.3 times the operating pressure (that
is 7.8 bar mini) for 10 minutes at least.
The test must be done at room temperature.
Ensure that all the air in the boiler is vented to avoid any bursting of the body.
Maintain pressure for at least 10 minutes. Any drop in pressure indicates a leakage in the boiler body.
