A. O. Smith Vertex power direct vent high-efficiency condensing gas tanks

A. O. Smith Canada publishes the Vertex Power Direct Vent as a sealed-combustion, high-efficiency condensing gas storage water heater for high-demand applications, including combined space and water heating. Combustion air is drawn from outside the home and a blower forces the exhaust outside, and the manufacturer documents the line in a 300/301 Series and a 400/401 Series, each with its own Canadian specification sheet, installation manual and wiring diagram.

The published feature set includes AiQ Adaptive Gas Technology, a fully submerged spiral-shaped condensing heat exchanger, ENERGY STAR qualification with 96% thermal efficiency, an advanced electronic control with a large touch screen display, a powered anode that comes standard on all models, and a Blue Diamond glass coating that A. O. Smith Canada describes as providing superior corrosion resistance compared to industry-standard glass lining. Thermal efficiency is a different measure from UEF and is not a savings percentage.

The Canadian site links the 300/301 and 400/401 Series specification sheets, installation manuals and wiring diagrams, plus a Vertex residential warranty sheet, all cited here, and states an 8-year limited tank and parts warranty. The line is documented at family level because the per-model capacities, first-hour ratings and inputs sit in the linked Canadian specification sheets, which are the source used before any model row is published. Whether CANRO supplies a Vertex Power Direct Vent for a project is confirmed at consultation, and CANRO names A. O. Smith among the brands it services on its own pages.
