bustion air pipes that traverse rewalls, the pipes/ducts must be designed so that re or
smoke cannot travel to other oors or areas.
Models S100-12 and S122-22 only
The fresh air pipe can be tted on both the right and left side.
The separate fresh air pipe and blind plate are fastened with 3 screws.
