Installing Body Assembly in an Open 1-Sided or 2-Sided Installation
Steel framing options are available for the open 1-sided

Rinnai provides a steel frame as a kit. Refer to the
separate detailed instructions for assembly of the steel
frame. To enhance the durability of any type of framing, it is
suggested that the frame is mounted on a paved slab
9.5 inches (250 mm) above unpaved ground and 5.9
inches (150 mm) above paved ground.
