Boiler Fuel Gas Natural gas used as a fuel for the generation of steam (or hot water). Boiler Pressure The pressure of the steam of water in a boiler depending on type generally expressed in pounds per square inch gauge and corresponding temperature. Boiler Rating
The boiler's automatic filling system controlled by the pressure-reducing valve should maintain the proper water level at 12 to 15 psi of pressure. If there isn't a pressure-reducing valve manually feed the boiler by opening up the water feed valve until the boiler pressure reaches 12 psi.
High Pressure Boiler: What is it? Types & Characteristics
The pressure and steam of a high pressure boiler is produced by burning a fuel such as coal natural gas or petroleum. The heated gases from the burning fuel are circulated by natural convection or forced by a pump. Forced circulation is produced by a centrifugal

Typical pressure for a residential boiler serving a two story home would show 12 psi cold and less than 30 psi hot. Over 30 psi boiler pressure will cause the pressure relief valve to open. Typical hydronic heating boiler operating temperature settings are LO-120-160 HI
