What is another setting on a single stage propane regulator?

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

Answer: (C)

In a propane regulator, the setting refers to the outlet pressure the regulator delivers to the appliance, measured in inches of water column. For single‑stage propane regulators, there are two common outlet pressures used to match different appliance demands: about 11 inches of water column and about 14 inches of water column. The question is asking for another widely used setting besides the more typical 11 inches; 14 inches of water column is that alternative. Appliances that need more gas flow or operate at higher pressure will use a regulator configured for the higher 14" wc setting. The other options—7" wc and 15" wc—aren’t the standard alternative for common propane single‑stage regulators, and 11" wc is the more typical setting, so 14" wc is the correct other setting.
