Hydraulic test [Required for field assembled assemblies]

After assembling the boiler body, the installer must car-

ry out a water tightness test at a pressure equal to 1.5

times the operating pressure (that is 5,2 bar minimum)

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 boi-

ler body.

After the tightness test, drain the boiler and remove

all the parts used for the test.
