FORCED EXHAUST
TYPE B23P - B53P
(fig. 9/a)
This. type. of. exhaust. pipe. is. installed. using.
the. special. kit,. code. 8089912/13.. For. kit.
assembly. instructions,. refer. to. point. 2.6..
Protect. the. intake. with. the. optional. acces-
sory,.code.8089501..
The.accessory.is.assembled.by.cutting.a.50.
mm. long. segment. from. an. ordinary. ø. 80.
extension. and. inserting. it. on. the. air. intake,.
on.which.the.accessory.is.then.fitted,.ancho-
red. to. the. pipe. segment. with. the. screws.
provided.(fig..9/a)...
Maximum flow resistance must be no more
than 10 mm H
O (version 12) - 15 mm H

(version 25-30-35) (ATTENTION: the total
length of each pipe should not exceed 25 m,
even if the total loss is below the maximum
applicable loss.)
As. the. maximum. pipe. length. is. determi-
ned. by. adding. up. the. flow. resistance. of.
the.various.individual.accessories.installed,.
refer.to.Table 1-1/a.for.calculation.
