The protective zone below the product extends as far as the
floor.
The right-hand corner of the building is shown here. Dimen-
sion C is the minimum clearance that must be maintained
to the wall (
Section 5.4). Dimension D varies for the left-
hand corner of the building.

Dimension A is a clearance around the product.
4.2
Design of the condensate discharge
The condensate that accumulates can be guided into a
sewer, pump sump or soakaway via a downpipe, gully,
balcony run-off or roof run-off. Open gullies or downpipes
within the protective zone do not pose any safety risk.
For all installation types, you must ensure that any condens-
ate that accumulates is discharged frost-free.
4.2.1
Design of the condensate discharge for
ground installation
For the ground installation, the condensate must be dis-
charged via a downpipe into a gravel bed which is located
in the frost-free area.

A
For a region with ground frost, dimension A is
≥
900 mm
and, for a region without ground frost, it is
≥
600 mm.
The downpipe must flow into a sufficiently large gravel bed
so that the condensate can trickle away freely.
To prevent the condensate from freezing, the heating wire
must be threaded into the downpipe via the condensate dis-
charge tundish.
4.2.2
Design of the condensate discharge for wall
installation
For wall installation, the condensate can be discharged into
a gravel bed that is located below the product.
Alternatively, the condensate can be discharged by con-
necting the condensate discharge pipe to a downpipe. In
this case, depending on the local conditions, you must use
electrical trace heating in order to keep the condensate dis-
charge pipe frost-free.
4.2.3
Design of the condensate discharge for flat-
roof installation
For flat-roof installation, the condensate can be discharged
by connecting a condensate discharge pipe to a downpipe or
a roof run-off. In this case, depending on the local conditions,
you must use electrical trace heating in order to keep the
condensate discharge pipe frost-free.
