The regulator air inlet discharge should be directed how, to maintain proper clearance?

• A. facing down 10 ft away from inlet
• B. facing up 10 ft away from inlet
• C. perpendicular to inlet, 10 ft away
• D. facing down 10 ft away from inlet

Answer: (A)

Direct the regulator’s air discharge downward and keep it a safe distance away from the inlet. Pointing the vent downward directs any vented air and condensate away from openings, intakes, and nearby equipment, reducing the chance that it will be drawn back into the inlet or into occupied spaces. A 10-foot clearance provides a practical buffer from doors, windows, and other openings, helping prevent backflow and ensuring safe operation. Directing the vent upward or perpendicular can increase the risk of re-entry or exposure, so the downward direction away from the inlet is the best practice.
