A gas meter must be located how many feet from the suction line?

• A. 3 feet
• B. 5 feet
• C. 10 feet
• D. 15 feet

Answer: (A)

Maintaining a safe clearance between a gas meter and nearby refrigerant piping is about safety and service access. A minimum of three feet from the suction line gives enough room to safely read and shut off the gas meter, plus enough space to access and work on the suction-line connections without interference. This separation also reduces the chance that heat, vibrations, or potential leaks from the refrigeration side could impact the gas meter area or complicate maintenance. While some installations might require more space for site-specific reasons, three feet is the standard minimum to meet safety and serviceability needs.
