• Use the screws in the parts bag to attach the duct collars to the
inlet and outlet of the ventilator. The outlet collar has a backflow
damper.
• The outlet duct collar may be attached to the top or end of the
unit. Move the outlet cover to the location not being used. See
Figure 2.
• Make sure there are no bends in the ductwork coming off the
outlet for a minimum of 4”. This will ensure that the ductwork will
