The Cyclone features power-vent and power direct vent design, allowing combustion air to be drawn from the equipment room
conventionally or directly from the outdoor atmosphere through a sealed intake air pipe. Vent systems can be terminated
vertically through the ceiling or horizontally through a sidewall. Front located exhaust and condensate connections allow for
easy installation and serviceability
