4 Installation
Fig. 4.1 Exhaust air installation – not permitted
Fig. 4.2 Exhaust air installation – correct
XXIf simultaneously operating both a fireplace and the cooktop
extractor in the same room, ensure that:
XO the maximum low pressure is 4Pa (4 x 10–5bar);
XO a safety device (e.g. window contact switch, low pressure
warning device) is used to ensure that a sufficient supply
of fresh air is guaranteed;
XO the exhaust air is not channelled into a chimney that is
used for exhaust gases of appliances operated with gas or
other combustibles;
XO the installation is checked and approved by an authorised
certified engineer (e.g. heating engineer).
i No window contact switches may be installed that
separate the control unit from the power supply (phase
separation). Only the Home In interface is to be used.
4.2 Checking the scope of delivery
XXMake sure the delivery is complete and check it for damage.
XXIf there are any missing or damaged parts, please notify the
BORA After Sales Service.
XXDo not under any circumstances install parts which are
damaged.
XXDispose of transport packaging in the proper manner (see the
“Decommissioning, disassembly and disposal” chapter).
XXObserve all safety and warning information (see the “Safety”
chapter).
XXFollow the enclosed manufacturer’s information.
4.1 General installation instructions
i The appliances must not be installed above cooling
devices, dishwashers, stoves, ovens, washing machines
or dryers.
i The contact surfaces of the worktops and wall sealing
strips must be made of a heat-resistant material (up to
approx. 100°C).
i Worktop cut-outs must be moisture-sealed using suitable
means and, where necessary, fitted with a thermal
insulator.
i External devices may only be connected to the cooktop
extractor connections provided.
i Extremely bright lights aimed directly at the appliances
can cause colour variations in the appliances and are
thus to be avoided.
4.1.1 Operating the cooktop extractor with a
fireplace that depends on the air in the
room
i National and regional laws and regulations must be
observed with regard to the exhaust duct design.
i A sufficient air supply must be ensured.
Fireplaces that depend on the air in the room (e.g. gas, oil,
wood or coal-fired heaters, continuous-flow water heaters,
instantaneous water heaters) draw in air from the room in which
they are installed and release the exhaust fumes into the outside
air via an exhaust system (e.g. chimney).
If the cooktop extractor is used in exhaust air mode, it draws
in air from the room in which it is installed as well as from
neighbouring rooms. If there is insufficient air supply, low
pressure will occur. Toxic gases could be drawn out of the
chimney or extraction ducting and back into the room.
