Dec 30, 2019 · High pressure can result from the boiler temperature being set too high. Higher pressures generally cause automatic shutdowns. Modern boilers have built-in pressure release valves. These generally trip at 30 psi and release excess steam to bring the pressure back to normal. Itll also kick off the power to your boiler.
Jan 12, 2014 · You need to confirm the accuracy of the limit control and the pressure temperature gauge. Replace as necessary. It's a boiler so the relief valve will open, or should open, at 30 PSI. Water in a boiler doesn't boil at 212 degrees because it operates at a higher pressure. If properly sized, the boiler shouldn't need to operate higher than 180 degrees.
If your heating boiler pressure is going up to 32 psi, a pressure higher than normal boilers heated to 180 or even 200 °F, and high enough to open the pressure/temperature relief valve, then I suspect
