GSW Power vent gas tanks

GSW publishes the Power Vent for the common case where conventional chimney venting is not an option. Air is drawn from inside the home while a rotatable motorized blower forces the exhaust outside. Because the blower can be repositioned, GSW describes the design as ideal as a replacement water heater in a variety of applications.

The published feature set includes factory-installed heat traps on the water inlet and outlet that GSW says reduce the amount of heat lost through piping, the TankSaver tank design, and a robust air intake snorkel that inhibits flammable vapours from entering the combustion chamber. A sensor detects flammable vapours and automatically disables the unit, and the state-of-the-art electronic gas control carries self-diagnostic capability that GSW says makes troubleshooting easy. Venting is flexible: the line can be vented with 2 in, 3 in or 4 in ULC S636 PVC, CPVC or polypropylene pipe up to 180 equivalent feet, with the installation manual controlling the full details.

The line is documented here at family level because the per-model capacities, first-hour ratings, inputs and UEF values sit in the linked Canadian spec sheet, which is the source used before any model row is published. The installation manual and residential warranty sheet are linked alongside it. Whether CANRO supplies a given GSW Power Vent model for a project is confirmed at consultation, and CANRO names GSW among the brands it services on its own pages.
