A = Offset
B = Length of air conduit

Note
The elbow delilvered with the flue kits 303 933
and 303 936 is not the same dimension as
shown here.
a
Caution!
This gives a corresponding exhaust-conduit
length of 190 + 40 = 230 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 ( = 190 mm in this case).
