What is the PSI range for a typical commercial gas setup?

• A. 0.5 - 1 PSI
• B. 1.5 - 2.5 PSI
• C. 2 - 4 PSI
• D. 5 - 10 PSI

Answer: (A)

Gas pressure in commercial systems is kept low and steady so burners fire reliably and safely. Equipment in these setups is designed to operate on modest pressure, with regulators delivering about half to one psi (roughly 14–28 inches of water column) to the appliances. This range provides enough flow for typical multi-appliance demand without overdriving the burners or stressing piping and regulators. If pressure is too low, burners may struggle to maintain flame and heat output; if pressure is too high, flames can become unstable, regulators can chatter, and components can be damaged. So, 0.5–1 psi is a common target for typical commercial gas systems.
