Mounting on the ceiling (Vallox 101 MV)
Vallox 101 MV can be equipped with an optional ceiling mount 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.
- The top edge of the white covering strip of the ceiling mounting plate can be installed against the ceiling. Alternatively, a concealed mounting method can be used, in which case the ceiling can be 30 mm below the top of the white covering strip.
Note: When installing the unit, reserve a space of at least 555 mm in front of the unit for servicing purposes.
Note: Mount the ventilation unit in a place where the temperature does not fall below +10°C.
Insulate the ducts against condensation also between the unit and the ceiling mounting plate.

Attach the ceiling mounting plate:
- Fasten the thread bars on the rafter frames or other frame structure, and turn the nuts onto the bars.
- Lift the ceiling mounting plate in place.
- Push a rubber damper and a washer to each thread bar.
- Adjust the nuts so that the ceiling mounting plate is level.
- Shorten the lower ends of the thread bars so that they are no more than 5 mm below the nuts.
-
Install the ventilation unit on the ceiling mounting plate:
Warning:
The ventilation unit is very heavy. Do not perform this procedure alone.
Attic floor penetration plate:
The attic floor penetration plate (D) is optional. When an attic floor penetration plate is used, the airtightness of the vapour barrier must be ensured.
The attic floor penetration plate can be fastened on the finished rear wall. The minimum distance of the attic floor penetration plate from the finished side walls is 15 mm.
