Fuel-Fired Heating Unit is defined as?

• A. Grade Plane
• B. Quick-Response (QR) Sprinkler
• C. Fuel-Fired Heating Unit
• D. Building Construction and Safety Code

Answer: (C)

In NFPA 13R, a fuel-fired heating unit is defined as a heating appliance that uses the combustion of fuel to generate heat for space heating. The correct choice is the term itself because the standard’s glossary defines that exact phrase. This matters in practice since fuel-fired heating units (like gas or oil furnaces or boilers) act as heat sources in low-rise residences, which can influence sprinkler placement, clearances, and spray coverage in areas where these units are located. The other terms refer to different concepts and are not the defined term for this question.
