Generated explanation

The illustration shows a house elevation with four sidewall vent terminations marked by red prohibition symbols to identify improper water-heater vent locations. The examples place vents beneath a window, near a gas regulator, close to grade, and low above a paved public walkway or driveway. Callouts specify separation distances from openings, the regulator, grade, and public paving. Additional annotations identify inadequate clearances from soffits, inside and outside corners, mechanical air inlets, and decks, balconies, or porches. A note cautions that the dimensions vary by area and circumstance and directs the reader to check local rules.
