SEPARATE PIPES ø 80
A special kit may be used to separate the
PT
flue gas outlet from the fresh air intake.
The intake may be installed to the right or
GB
left of the flue gas outlet.
Both ducts may be oriented in any direction.
Refer to fig. 10 for positioning.
The maximum overall length of the intake
and exhaust ducts depends on the head
losses of the single fittings installed
(excluding the doublers) and must not be
greater than 15,5 mm H
For head losses in the fittings, refer to
Table 2.
