Required minimum gaps/assembly clearances

Both for the installation/assembly of the appliance and
for carrying out maintenance tasks later, you need the
minimum gaps and assembly clearances given below:
Fig. 3.3 Required minimum gaps/assembly clearances
Leaving gaps to the sides is not necessary.
Furthermore, it is not necessary to keep a gap between
the appliance and components made of combustible
constituents, since at the rated heating power of the ap-
pliance, the temperature here is never higher than the
permitted temperature of 85 °C.
