Installation Guide

Roughing-In
IMPORTANT! All dimensions are nominal. The tolerance of the stud pocket is +1/4″ (6 mm) and -0″ (0
mm). Carefully measure your fixture before determining enclosure size. When a fire-rated wall is specified,
dimensions are to the inside of the wall board. Some shimming between the stud frame and the fixture
may be required. Dimensions given in the roughing-in information are crucial for proper installation.
Construct the framing and plumbing accurately.
NOTE: If a firewall is required, increase the roughing-in dimensions of the unit according to the thickness
of the firewall material. Dimension of the stud pocket must take into account the thickness of the firewall
material and may need to be adjusted.
NOTE: If the unit will be installed against a masonry wall, make provisions for plumbing connections.
Construct a separate frame wall a minimum of 6″ (15.2 cm) from the masonry wall.
