At what operating pressure should the oil safety switch activate?

The oil safety switch is designed to protect the heating system by monitoring the oil pressure within the system. It typically activates at a pressure range of 20 to 25 psi. This specification ensures that the oil burner operates safely and efficiently, preventing potential malfunctions or hazardous conditions caused by insufficient oil pressure.

When the oil pressure drops below this designated range, the safety switch automatically shuts down the system to avoid further operation under unsafe conditions, which could lead to damage or failure of the heating equipment. This range is established based on the requirement for adequate fuel delivery while preventing operational hazards related to low pressure. Having the safety switch activate within this specified range ensures the reliability of the heating process while safeguarding against leaks and other risks associated with improper oil pressure levels.
