Vent termination distance rule from a service regulator is described as which of the following?

Vent termination distance rule from a service regulator is described as which of the following?

• A. A vent shall not terminate within 2 feet, 3 feet, 4 feet, or 5 feet of a service regulator.
• B. Termination distance is unlimited.
• C. Terminating at 6 feet is allowed.
• D. Distance must be greater than 1 foot.

Answer: (A)

The rule is about keeping a safe clearance between the regulator’s vent and where another vent terminates. Vented gas must not end within a short distance from the service regulator, creating a prohibited zone that extends up to five feet. In practical terms, this means the termination must be farther away than five feet, so a six-foot termination would be acceptable. The statement that describes this prohibition—not terminating within those specific short distances—best captures the regulation’s intent. The other options misstate the rule: it isn’t unlimited, it isn’t defined by a single fixed distance, and it isn’t a requirement to stay only slightly more than one foot away.
