Aug 30, 2017 · While raising the pressure, the identified test team should go around the boiler for inspection. Once the Boiler pressure is raised to 10 kg/ cm2 (g) stop the pump and observe the pressure drop. Boiler Hydrostatic testing pressure gauge. If no leakage is observed to the satisfaction of the inspecting personnel, start the pressurizing pump. Raise the pressure gradually to 25% of the hydro test pressure …

This page lists all the available installation manuals for the A. O. Smith water heaters: electric, gas-fired, indirect, solar thermal, storage vessels.
Classification of boilers – High-pressure boilers are boilers operating at a steam or other vapor pressure in excess of 15 psig, or a water or other liquid boiler in which the pressure exceeds 160 psig, or has a temperature greater than 250 degrees Fahrenheit. Others are low-pressure boilers. License requirement
