At what gas pressure will redundant gas valves on furnaces shut down?

Redundant gas valves on furnaces are safety features designed to ensure that gas flow is accurately controlled and that the furnace operates within safe parameters. The shut-down pressure for these valves is crucial for preventing excessive gas flow, which could lead to unsafe conditions or potentially hazardous situations.

When we consider the shut-down pressure, 13.5 inches water column (W.C.) is the established threshold for many gas valve systems to ensure that they operate safely under normal conditions. When the gas pressure exceeds this limit, the redundant valve mechanism activates, shutting off the gas supply to protect the furnace and the system as a whole.

This specific pressure point reflects the design standards and safety protocols that are typically enforced in the heating industry. It's important for technicians and system designers to understand these specifications, as they play a vital role in ensuring the safe and efficient operation of gas furnaces. Thus, the selection of 13.5 in. W.C. as the shut-down pressure aligns with established industry practices regarding gas valve functionality.
