Which organization sets standards for combustion venting?

Which organization sets standards for combustion venting?

• A. UL
• B. ASHRAE
• C. NFPA
• D. OSHA

Answer: (C)

Standards for combustion venting are established by the National Fire Protection Association. NFPA develops codes that specify how venting systems for combustion appliances must be installed and operated to prevent hazardous fumes and fire risks. Key NFPA documents cover vent sizing, materials, clearances, installation, and termination, helping ensure safe exhaust of combustion products. Building codes commonly reference these NFPA standards to enforce proper venting. Other organizations play different roles. UL focuses on product safety testing and certification rather than setting venting installation standards. ASHRAE concentrates on ventilation design and indoor air quality, but isn’t the primary body that sets combustion venting requirements. OSHA handles workplace safety regulations and may reference NFPA codes, but does not itself set general venting standards.
