Table 2.6 Length of surplus with 45° bends
Key
A = Offset
B = Length of air conduit
C = Height
a
Caution!
This gives a corresponding exhaust-conduit
length of 284 + 40 = 324 mm.
Example:
An offset of 400 mm is measured. This value is then
used, along with the table below, to determine the
length of the air conduit (= 284 mm) and the height
(= 420 mm).
