A payback calculation can show how long new equipment will take to pay for itself, meaning the money that would have been used to operate an old

Your guide to safer boiler operation

2018-6-20 · All safety valves should be kept free of debris by testing the safety valve regularly. This should be done when the steam pressure is at approximately 75 percent of the safety-valve set pressure. Safety and safety-relief valves on low-pressure boilers should be tested at least quarterly, this is in accordance with the National Board Inspection

Understanding Combustion Safety-Valve Standards

FM For gas-fired, single-burner boilers and furnaces, FM requires two safety shutoff valves equipped with visual indication and proof-ofclosure switches. It also mandates position indication for safety shutoff valves to burners or pilots. Valves should be approved for FM Class 7400 liquid and gas safety shutoff.
