Lesson 1Venting, burning air and water drop handling: air vs power venting, direct-vent vs B-vent, water drop trap and drain for high-work unitsThis explains venting choices for gas water heaters, including air and power vent systems, direct-vent and B-vent setups, and right water drop trapping, clean, and draining for high-work no-smoke units.
