A. O. Smith ProLine XE atmospheric vent gas tanks

A. O. Smith Canada publishes the ProLine XE Atmospheric Vent as a residential gas storage water heater with a flue damper, which the manufacturer describes as providing increased energy efficiency and performance. Air is drawn from inside the home and the exhaust is vented into a chimney or through the roof, so it suits a home that already has a suitable chimney or approved vertical vent route. Because the flue damper is a powered component, A. O. Smith Canada states the unit plugs into a standard 110/120 V outlet with a 10 ft power cord included.

The published construction includes a CoreGard magnesium anode with a stainless steel core that A. O. Smith Canada says protects the tank against corrosion, and the manufacturer describes the ProLine XE models as residential water heaters with commercial-grade quality. The Canadian site links a specification sheet, installation manual, wiring diagram and the residential warranty sheet, all cited here, and states a 6-year limited tank and parts warranty.

This page is written at family level because the per-model capacities, first-hour ratings and inputs sit in the linked Canadian specification sheet, which is the source used before any model row is published. A. O. Smith Canada does not print a numeric efficiency for the line on the product page, so none is recorded here. Whether CANRO supplies a ProLine XE Atmospheric Vent for a project is confirmed at consultation, and CANRO names A. O. Smith among the brands it services on its own pages.
