MOUNTING ON THE WALL
NOTE
Avoid mounting the unit on a hollow, echoing partition
wall or on a bedroom wall, or prevent the conduction of
sound.
Note that during mounting the unit rises 10 mm higher
than the final height.
Mount the ventilation unit on the wall with a mounting plate,
as shown in the adjacent figure. Make sure that the unit is
horizontally level after mounting.
Vallox 51K MV must be mounted so that the clearance between
the bottom of the cooker hood and the cooker top is at least
426 mm in case of an electric stove and 650 mm in case a gas
stove. The clearance is 134 mm (i.e. the height of the cooker
hood) more between the bottom of the ventilation unit and the
cooker top.
MOUNTING ON THE CEILING
Vallox 51 MV can be equipped with an optional ceiling mounting
plate. To attach the ceiling mounting plate:
• On rafter frames or other frame structure with M8 thread
bars so that they withstand the weight of the unit.
• Ensure that the installation plate is horizontally level, as this
determines the position of the unit.
Insulate the outdoor air and exhaust air duct against
condensation also between the unit and the ceiling mounting
plate.
Mounting the ceiling mounting plate
1. Fasten the thread bars on the rafter frames or other frame
structure, and screw the nuts onto the bars.
2. Lift the ceiling mounting plate in place.
3. Push a rubber damper and a washer to each thread bar to
the cup of the plate.
4. Turn the nuts to make sure that the unit is horizontally level.
5. Shorten the lower ends of the thread bars so that they will
be at no more than 10 mm from the lower surface of the
ceiling mounting plate.
CAUTION
The ventilation unit is very heavy. Do not perform this
procedure alone.
NOTE
A space of at least 330
mm must be reserved
in front of the unit for
maintenance purposes.
