Installation in Masonry Walls
A typical method of installing the wallbox in a masonry
wall opening is illustrated in Figure 72.
Grout the top and bottom of the wall box frame as noted.
A sloped water dam located in the space between the unit
and wall facilitates moisture drainage. Grouting at the
ends of the intake box will complete the seal between the
wall box frame and the masonry opening.
Installation in Curtain Walls
In all cases, the wall intake box should be caulked to
provide a tight, weatherproof seal (see Figure 73, p. 111).
Note: A minimum of 2-1/8 in. of clearance must be
maintained between the exterior wall and back of
the unit. Failure to provide this gap will not allow
the wall box to fit properly.
