Which term is defined as an appliance producing heat by burning fuel?

• A. Fuel-Fired Heating Unit
• B. Heat-Actuated Device
• C. Quick-Response (QR) Sprinkler
• D. Grade Plane

Answer: (A)

Fuel-fired heating unit is the term used for an appliance that produces heat by burning fuel. It relies on combustion of a fuel (like gas or oil) to generate heat, which is then used to warm the space or water. In contrast, a heat-actuated device refers to a sprinkler component that responds to heat to release water, not a heater. A Quick-Response sprinkler is a type of sprinkler designed for faster activation, and a grade plane is unrelated to heating equipment. So the term that fits the description is fuel-fired heating unit.
