• A. NFPA 54
• B. the GAMA venting tables
• C. the manufacturer's instructions
• D. NFPA 211

Answer: (C)

Listed direct-vent equipment is approved for venting only as described by the listing. Following the manufacturer’s instructions ensures the venting method, materials, maximum lengths, terminations, and clearances are all within what the appliance has been tested and approved to use. The Minnesota Fuel Gas Code provides the jurisdictional requirements that must be met, so using the manufacturer’s guidance together with the state code keeps the installation safe and compliant. Other resources like NFPA 54 or venting tables can inform venting practices, but they do not replace the specific instructions provided by the manufacturer for that unit.
