Super Efficiency XV 90
Variable Speed Gas Furnace

-Anatomy-

TWO STAGES ARE BETTER THAN ONE!

Most conventional furnaces heat your home with a single "full-blast" speed. Not the XV 90. It's two-stage heating virtually eliminates the discomfort of temperature swings caused by short-cycling - a situation common to single-stage furnaces.

Sidewall vent termination kit

The XV 90 is also designed with a direct vent option. A furnace may be exposed to corrosive materials in your home which could lead to component damage. Direct venting avoids exposure to these elements by using 100 percent outdoor air for combustion. This two-pipe design allows the vent gases to flow through one pipe while fresh outside air flows through the other.

The stylish sidewall vent termination kit (shown above) provides a nice, finished appearance outside your home.
