Apr 23, 2017 · Clean the boiler and adjust its pH if needed. Too-high pH in boiler water (water that is alkaline or "basic") causes frothing and surging. pH in a steam boiler should be between pH 7 and pH 9. A leak in a tankless coil used to make domestic hot water (not found on all steam boilers) will leak higher pressure (building water supply pressure

Boiler Safety - OSHA

With the boiler pressure at a minimum of 75% of the safety valve set pressure, the safety valve try lever is lifted to wide open position. Steam is discharged for 5 sec to 10 sec. The try lever is released, and the disk should snap to the closed position against the valve seat. Malfunctioning safety valves must be replaced as soon as possible.

Feb 27, 2014 · As you can guess, it will shut off power to the burner if the gas pressure is below the set point. The high-gas pressure switch will be located between the last manual gas valve and the burner. Many are located atop the burner housing. This will shut off power to the burner if the gas pressure is too high. These controls usually have a manual reset that will require resetting if they trip. Many gas pressure …
