What must be the side clearance when installing a LP boiler?

• A. 18 inches
• B. 12 inches
• C. 24 inches
• D. 36 inches

Answer: (A)

Eighteen inches. This minimum side clearance around an LP boiler is required to keep nearby combustible materials safe from heat and to give technicians room to access and service the unit. Having that space ensures heat from the boiler won’t ignite nearby surfaces and allows enough room to remove panels, inspect connections, and work on piping or controls. A smaller gap would not meet installation standards and could create a safety or maintenance issue, while more space is optional but not required by the minimum rule.
