A: A variety of flame detection methods exist. Most designs utilize either a flame’s electrical continuity or its radiation to determine the presence of a flame. The basis of selecting
A: Valve proving is a valuable safety upgrade to any combustion system. A variety of valve proving systems exist, but they essentially perform an automated test of gas safety valves
A: At a minimum there are two crucial gas pressure switches in a valve train, one for low pressure and one for high pressure. The low gas pressure switch ensures
A: Besides accommodating thermal expansion, flexible joints (compensators) isolate the valve train from potentially harmful piping-induced stresses such as vibration or piping misalignment. The potential of safety equipment malfunctioning due
A: When a building’s service pressure exceeds an appliances’ inlet pressure capability, a line regulator is added to manageably reduce the pressure. But if that line regulator were to fail,
A: Yes! For a variety of reasons, burner control shifts as operating conditions change and controls drift. Mechanical devices have components that age over time. Elastomers deteriorate and often become
A. Improper venting is among the most common installation error. Numerous components require an atmospheric reference for accurate operation. Many of these devices however can fail in modes that permit
