Water drainage
A drain pipe comes out from the rear of the appliance, to drain the oven cavity. This pipe must
be connected up to a pipe made to resist steam temperatures (90°C-100°C) with an internal
diameter of 16 mm (DN 16). To prevent choking, it is best to use a rigid pipe and make sure
there are no "elbow" bends anywhere along the drain line.
Furthermore, the drain line must slope down (minimum slope 5%) along its full length (the
length in question is from the appliance's drain pipe to the drain point and must not exceed 2
metres). The drain line must run into an open floor drain (Fig.1). In addition, there must be a
free air gap of at least 25 mm (distance between the drain line coming from the appliance and
the funnel on the drain standpipe). Whatever the case, in order to comply with current hygiene
standards, the line connected to the appliance's drain pipe must not come into direct contact
with the drain point. It is advisable to include a suitable trap in the line connecting the
appliance's drain outlet to the grey water waste system, thus stopping the steam coming back
out of the drain.
