VENTING Rinnai Tankless Water Heaters use a unique Concentric Venting System - a single-vent assembly featuring an inner tube for exhaust and an outer tube for fresh air from outdoors. The result is a direct-vent, sealed-combustion system that offers safety and performance. Con- densing units (Ultra Series) use a polypropylene inner pipe designed to withstand higher temperature conditions than more commonly used alternatives. The Concentric Venting System makes installations fast and easy. Single penetration through wall reduces install time and costs. Simple positive fi t-and-lock components ensure secure connection. Joint seals expand and contract with weather to prevent damage.
