How far must the fill pipe for fuel oil systems terminate from any building opening at the same or lower level?

The fill pipe for fuel oil systems must terminate at least 2 feet from any building opening at the same or lower level to ensure safety and prevent any potential hazards associated with fuel oil spillage or leakage. This distance is critical in mitigating the risks of vapor intrusion into the building, as fuel oil can release vapors that may pose health and fire safety risks.

By maintaining a minimum separation distance, the code helps to create a barrier that minimizes the likelihood of vapors entering through doors, windows, or other openings. Adhering to this requirement is essential for the safe installation and operation of fuel oil systems, ensuring compliance with the International Mechanical Code and promoting safe practices. This standard is part of broader safety regulations designed to protect both occupants of the building and the structural integrity of the property itself.
