5.1.2 Adjustable height of the plenum; (with the plenum extension cut off (A)).
When the ceiling height, measured from the
floor is greater than 72" (183 cm), but less
than 84" (213 cm), it will be possible to cut
the plenum extension (A) of at most
10" (254 mm). The plenum extension (A)
must therefore have a minimum height of
14'' (356 mm).
Warning: The plenum extension (A) should
not obstruct the openings for the hot air
distribution of the plenum (B). The shaded
area represents the maximum cutting of
plenum extension (A).
5.1.3 Adjustable height of the plenum (A and B); (without cutting) 79" (200 cm) to
88" (224 cm).
For ceiling height greater than 84" (213
cm).
