The maximum overall length of the intake
and exhaust ducts depends on the head
losses of the single fittings installed and
must not exceed than 6,00 mm H

O.
During installation use only original SIME
accessories and make sure that the con-
nection is carried out properly, as indicated
in the accessory instructions.
For head losses in the fittings, refer to
Table 1
