When the Rinnai Continuum is installed on exterior wall, it requires no additional venting accessories.
For indoor installations, the Rinnai Continuum exhausts air through a 3" pipe within the center of a 5" intake pipe.
This Rinnai Continuum advantage results in only one wall or roof penetration, and it uses no indoor makeup air.
