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.
Use at least a PP-type drainage pipe that withstands steam temperatures. Do not use a rubber pipe.
Fig. 1
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).
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).

CAUTION: Consider that stacked units and model 161 have 2 drains. The development of a vented drain may facilitate installation and correctoperation.
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.
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.
