Vent Type

Chimney Vent (17)

Direct Vent (68)

Power Vent (107)

Seperated Combustion (30)

Configuration

Orientation describes the direction that air will flow through a piece of equipment. (e.g. air will flow horizontally through a "Horizontal" unit heater.) Most equipment will only function properly if installed in the proper orientation.
