A low fire pressure switch is a mechanical device that can open the gas supply to an appliance (such as a furnace or boiler) when the system's temperature is too low. This switch prevents the possibility of back drafting and, therefore, protects not only itself but also the appliance and the building's occupants. The 12W48 Series is a 4-wire low fire pressure switch which is designed to fit Lennox Packaged Terminal Air Conditioners.

Lennox low fire pressure switches help protect the home and its inhabitants from potential fires. Pressure switch devices assist in the detection and control of a potentially dangerous pressure build up in steam lines which can occur due to freezing water or steam, high demands on incoming cold water supply, or a long distance between the boiler and the heater.

The Lennox® Low Fire Pressure Switch is used in Lennox® Heat Recovery Ventilators to open the damper when a low fire temperature is detected. It also contains a pilot flame sensor that provides continuity to the blower relay.

The 12W48 is a low fire pressure switch manufactured by Lennox, to be used with their residential heating equipment. This unit is designed with a copper tube and a stainless steel bimetal disc, making it similar to other venting switches available on the market.
