What is the minimum distance a fill pipe must terminate outside from any building opening in a fuel oil system installation?

In fuel oil systems, safety and regulatory compliance are crucial. The minimum distance a fill pipe must terminate outside from any building opening is primarily established to prevent the risk of flammable vapors entering the building and to mitigate potential hazards associated with spills or leaks.

A termination distance of 2 feet is typically required as it provides a safe separation that reduces the likelihood of fuel vapors or accidental spills affecting doors, windows, or other openings of the building. This distance helps ensure proper ventilation and minimizes the risk of fire or explosion in case of a leak.

The regulations may vary by local codes, but a consistent minimum standard of 2 feet is a common requirement in many jurisdictions, which is why this choice is considered correct. Always verify local building codes for specific requirements, as they can dictate variations based on environmental conditions and local safety standards.
