How many feet does the regulator vent have to be from the sources of ignitions?

• A. 3 ft
• B. 5 ft
• C. 10 ft
• D. 20 ft

Answer: (B)

Gas venting from a regulator can release propane, so you need a safe clearance from anything that could ignite it. Five feet gives a practical buffer that helps propane dissipate in open air and reduces the chance that vapors reach sparks, flames, or hot surfaces. It also accounts for wind and slight positioning variations during installation, keeping ignition sources well out of reach. While smaller distances offer less margin and larger distances are more than necessary for typical setups, five feet is the standard that balances safety and practicality.
