Application
For units with optional gas furnaces (Model Digit 17=2, 3, 5,
or 6), the standard power exhauster discharge configuration is
a horizontal exhaust cover for non-condensing (81% efficient)
furnaces and a downturn elbow for condensing (90%+ efficient)
furnaces. In certain installations, such as close proximity to
adjacent equipment or parapet walls, it is desirable to redirect
the products of combustion vertically through an extended vent
kit that terminates above the top of the unit as shown in Figure
1.1. Agency approved extended vent kits are available for field
installation as detailed on the following pages.
