What is the minimum height off the floor that an oil-fired appliance is to be suspended?

• A. 12 inches
• B. 6 inches
• C. 8 inches
• D. 4 inches

Answer: (B)

The main idea is safety and serviceability for suspended oil-fired equipment. Requiring a minimum of six inches clearance off the floor keeps heat and any potential oil leaks from coming into contact with floor coverings or combustibles, reducing fire risk. It also provides space for a drip pan or containment if a leak occurs and gives technicians room to access and service the burner and connections without the unit sitting directly on the floor. This height is a common standard in installations to balance safety, maintenance access, and practical installation.
