Filter on the gas pipe
The gas valve is supplied ex factory with an
inlet filter, which, however, is not adequate
to entrap all the impurities in the gas or in
gas main pipes.
To prevent malfunctioning of the valve, or in
certain cases even to cut out the safety
device with which the valve is equipped,
install an adequate filter on the gas pipe.

Discharge Pipe
See fig. 6 for example discharge pipe termi-
nations.

INSTALLATION OF COAXIAL DUCT
(ø 60/100 - ø 80/125)
The axial suction and discharge pipes are
supplied in a special kit (that can be purcha-
sed separ at el y) along wit h assembl y
instructions. The diagrams of fig. 7 illustra-
te some examples of different types of
discharge modalities allowed and the maxi-
mum lengths that can be reached.
2.6
INSTALLATION OF SEPARATE
DUCTS (ø 80)
Separate duct kit code 8089911 is used to
connect twin 80mm pipes. See fig 8.
The maximum overall length of the flue is
determined by the head losses of the indivi-
dual components and must not exceed
15mm H
2
O. Additionally the length of either
the inlet or exhaust pipe must not exceed
50 m. See
Table 1
for information on the
load losses of single accessories and
Fig. 9
for types of “smoke outlet”-”air inlet”.
