John Wood ProLine XE atmospheric vent gas tanks

ProLine XE atmospheric vent is John Wood's natural-draft residential gas tank line, described by the manufacturer as residential water heaters with commercial-grade quality. Flue gases leave through a chimney or approved vertical vent, and the line adds a flue damper, which John Wood states increases energy efficiency and performance by limiting heat loss up the flue when the burner is off.

The published feature set is aimed at efficiency and sediment control: built-in heat traps on the water inlet and outlet reduce the heat lost through the piping, a turbulator dip tube reduces sediment build-up at the bottom of the tank, and the glass lining provides protection against tank corrosion. The line plugs into a standard 110/120 V outlet with a 10 ft power cord included, which is the flue-damper connection rather than a blower.

John Wood publishes 0.69 UEF for this family. WaterHeating.ca records that as the manufacturer's published value; the draw pattern is not stated on the product page, and the per-model capacities, first-hour ratings and inputs sit in the linked Canadian spec sheet, which is the source used before any model row is published. A replacement of an existing atmospheric gas tank is permitted gas work in BC, and whether CANRO supplies a specific ProLine XE atmospheric model for a project is confirmed at consultation.
