during installation:
– Insulate the exhaust pipe and install a
condensation collection system at the
base of the vertical pipe.
– If the pipe passes through combustible
walls, insulate the section of the flue pipe
passing through the wall with a 30 mm
thick fibreglass pipe covering with a den-
sity of 50 kg/m
In "25-30 Solar" models this type of exhaust
pipe is installed using the special kit, code
8089904. For kit assembly instructions,
refer to point 2.9. 1 . Protect the intake with
the optional accessory, 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 pro-
vided (fig. 11). Kit code 8089904 is supplied
with the intake diaphragm, which must be
used as shown in fig. 9/a, depending on the
maximum permitted flow. Maximum flow
resistance must be no more than 7.6 mm

"30 Solar". As the maximum pipe length is
determined by adding up the flow resistance
of the various individual accessories instal-
led, refer to Table 1 for calculation.
