A propane service regulator would normally deliver pressure at?

A propane service regulator is designed to reduce the pressure of propane to a usable level for appliances. Typically, these regulators deliver pressure in terms of water column (w.c.), which is a standard measurement used in the gas and propane industry.

The correct range for a propane service regulator is generally between 5 to 11 inches of water column, depending on the specific application and appliance requirements. Therefore, delivering pressure at a range from one pound (which is equivalent to approximately 27.7 inches w.c.) down to 11 inches w.c. is within the operational parameters for this type of regulator. This ensures that the propane appliances receive a consistent and safe pressure level for optimal functioning.

The other options do not fall within the standard operating range for a propane service regulator. For example, delivering pressure in ounces to any specified height is not typical for gas service regulators, as they are measured in inches of water column for practicality and safety in providing the right pressure to the appliances.
