After assembling the boiler body, the installer must
carry out a water tightness test at a pressure equal to
1.5 times the operating pressure (that is 135 Psig Max.
of 145) a minimum 20 minutes. The test must be done
at room temperature with a city water tempreature not
less than 60°f/15°C.
Fit a square flange with hole facing upwards onto

Maintain the required pressure for at least
20 minutes at 135 Psig. Any drop in pressure
indicates a leak in the boiler body.
After the hydrostatic test, drain the boiler and
remove all the parts used for the test.
