The appliance must only be connected by an
authorised specialist. The specialist is respon-
sible for perfect functioning of the appliance at its
installation location. He must explain the operating
principle of the appliance to the user with referen-
ce to the operating instructions. He must explain
to the user how the appliance can be isolated from
the mains whenever required.
The exhaust air can be routed into a ventilation
shaft or directly into the open through the outside
wall. Adequate incoming air must be ensured
whenever the hob ventilator is operated in the
exhaust air mode and firing systems dependent
on a chimney are operated at the same time.
It is not allowed to pass the exhaust air into a flue
or exhaust air chimney that is in operation or into a
shaft that is linked to the heating basement. Consult
the chimney sweep responsible for your district
whenever you wish to pass the exhaust air into a
chimney that is not in operation.
During the course of planning, a chimney sweep
must be consulted if a room air-dependent hearth
is operated in the same room as the one in which a
hob ventilator is operated in the exhaust air mode.
Adequate incoming air must be ensured. The appli-
cable construction and safety regulations must be
observed.
Adequate incoming air must be ensured if a wood,
coal, gas or oil heater or an open hearth is operated
in the same room as the one in which the wall hood
is installed.

Adequate ventilation of the room must be
ensured whenever a hob ventilator is operated
simultaneously with devices that are operated with
non-electrical energy. Official regulations must be
observed with regard to removal of the exhaust air.
The applicable regulations of the power supply
companies and the regional construction regula-
tions must be observed when installing the hob
ventilator.
Safe operation is possible whenever the partial
vacuum in the place where the firing equipment is
installed does not exceed 4 Pa (0.04 mbar). This
can be achieved whenever the air needed for
combustion is able to enter through openings that
cannot be sealed, for example in doors, windows,
incoming/exhaust air wall boxes or other technical
means.
Flexible aluminium pipes, corrosion-protected
sheet metal pipes and exhaust air pipes whose
material conforms to fire B1 in accordance with
DIN 4102 can be used. Exhaust air pipes should
have a nominal diameter of 125 mm / 4
The lateral distance from the appliance installed
next to it must amount to 8 mm /
If two Vario appliances are used, the hob venti-
lator must be installed between the appliances.
If 4-plate hobs are used, it is recommended to
place two ventilation devices to the left and right of
the hob. Owing to the high air output, an adequate
supply of air is required.
To prevent the ingress of water, e.g. condensate
or rain water from an uncovered exhaust air shaft,
our condensate separator RV 060-150 must be
installed in the exhaust air line. The condensate
separator must still be acciessible after installation.
