Regulators that reduce the vapor pressure of fuel gas to not more than 20 psi are required for all installations within structures or confined spaces unless the burner or appliance specifically requires a higher pressure and equivalent safety is provided. The use of regulators or automatic pressure-reducing valves shall be limited to the pressures and the types of gases for which they were designed. Regulators are required for installations where a fuel gas hose is between fuel source and burner.
