Caution:
If the minimum clearances are not maintained, the
efficiency of the product may be affected.
▶
To guarantee sufficient air flow and to facilitate mainten-
ance work, observe the minimum clearances that are
specified above.
▶
Ensure that there is sufficient room to install the hydraulic
lines.
▶
If the product is to be installed in areas where heavy
snow falls, ensure that the snow does not accumulate
around the product and that the minimum clearances
specified above are observed. If you cannot ensure this,
install an additional heat generator in the heating circuit.
An elevating socket is available as an accessory. In order
to adapt the product to higher levels of snow, only use
the Vaillant elevating socket.
