8 • WATER AND DRAIN CONNECTIONS
For the range with the drain as per fig.1 it is
possible to make a direct connection with an air
trap, without fitting a drain cup, as the drainage
manifold system has an internal air drop (Fig. 2).
In the case of floor drains without trap, an air gap
must be developed with a minimum clearance of 2
cm. (Fig. 3).
For the remaining models an air gap cup must
be interposed guaranteeing a minimum clearance
of 25 mm between the appliance’s plastic drain
bend and the drain piping. Direct connections
are prohibited.
8.5 • DRAINING
The water is drained off by gravity through
a heat-resistant pipe DN 50 (not flexible),
maximum length 2 m, installed at an angle
of no less than 4°.
Mean temperature of the drain water: 65 °C.
WARNING:
The drain must be outside the oven perimeter, Min. 300 mm./1 ft.
and Max. 2000 mm / 7 ft.
It is prohibited to reduce the drain diameter.
