  Installing Body Assembly in an Open 1-Sided or 2-Sided Installation   

Steel framing options are available for the open 1-sided 
and open 2-sided installations.  For ease of installation, 
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. 

If framing is made of a combustible material, ensure the following minimum framing dimensions and clearances:
