Description
The Weil McLain 383-600-049 Low Gas Pressure Switch is a monitoring component that detects when gas supply pressure falls below the required operating level in HVAC systems. It is installed in compatible boilers and other gas-fired heating equipment to monitor fuel pressure during system operation. When low gas pressure is detected the switch interrupts the control circuit to prevent improper burner operation. As part of the appliances safety and control system, it supports accurate performance, proper combustion conditions and consistent equipment operation.
