How far should a vent termination be mounted from an oil tank vent or gas meter?

The correct answer is that a vent termination should be mounted a distance of 3 feet from an oil tank vent or gas meter to ensure safety and proper function of the venting system. This requirement is established to prevent potential hazards associated with gas accumulation and ensure that harmful gases do not enter living spaces or areas where they could present a risk.

By maintaining this 3-foot distance, the design minimizes the likelihood of cross-contamination between vented fumes from the oil tank or gas meter and other vented exhausts, promoting a safer environment. This spacing also accounts for the potential dispersion of vented gases, allowing for adequate airflow and reducing the risk of ignition or other safety concerns that could result from proximity to gas sources. Hence, following this requirement is essential for compliance with safety standards outlined in the North Carolina Mechanical Code.
