What is a setting on a single stage propane regulator?

• A. 7" wc
• B. 11" wc
• C. 14" wc
• D. 15" wc

Answer: (A)

The setting on a single-stage propane regulator is the outlet pressure it maintains for the downstream gas system, expressed in inches of water column. A single-stage regulator uses a spring to hold that downstream pressure at a fixed value; as gas flows, the regulator adjusts to keep the pressure near that set point. For typical residential propane systems, seven inches of water column is the common fixed outlet pressure, which is about 0.25 psi. This level provides enough pressure for burners to light and maintain proper flame without overloading equipment. The higher values listed (about 11" wc or more) are more associated with other gas types or special applications, and would be excessive for standard propane appliances, potentially causing improper operation.
