Before operating the boiler feed pump or oil supply pump, ensure all valves in the line are open or properly positioned. control on a hot water boiler should be set slightly above the highest desired water temperature and within the limits of the pressure vessel. Maximum pressure the inlet piping can experience during normal operation

What is the correct temp setting for a hot water boiler

Your boiler is a block of iron that wants to remain warmer than the spent flue gasses (140F for gas, maybe 130F for oil). Let's call it 140 to be safe. If you set your boiler operating temperature below that for extended periods the flue gasses will condense, form acidic deposits and eat the boiler.

What is a Maximum Allowable Working Pressure …

Maximum allowable working pressure is used when rating pressure-relief devices that protect vessels. It is also used to rate components such as piping, steam drums, tubes, boilers and any pressure vessels in hydraulic systems. The operating pressure is the pressure that a vessel is subjected to when in service.
