VENTILATION THE RIGHT WAY
V E N T I L A T I O N & H E A T R E C O V E R Y
9.1.1 Planning the wall breakthrough for new builds
► Commission an architect or design professional to include the wall breakthrough at
a suitable point in the construction drawing and execute it when constructing the
building shell.
There are two possible versions of the wall breakthrough:
— Wall breakthrough with recess (see Fig. 8) for installation kit
without
filler piece
M-WRG-II M/Fü
— Complete wall breakthrough (see Fig. 9) for installation kit
with
filler piece
M-WRG-II M/Fü
9.1.2 Breaking through an existing wall
WARNING
Danger due to damaging supply lines and changing the stress loadings
► Make sure that there are no supply lines in the vicinity of the wall breakthrough (e.g.
power, gas or water).
► Make sure that the wall breakthrough does not affect the local static loading require-
ments.
► Fit a lintel if necessary.
► Break through the wall. There are two possible versions of the wall breakthrough:
— Wall breakthrough with recess (see Fig. 8 on page 17) for installation kit
without
filler piece M-WRG-II M/Fü
— Complete wall breakthrough (see Fig. 9 on page 17) for installation kit
with
filler
piece M-WRG-II M/Fü
9.2
Chasing out channels for connecting cables
► Chase out a channel for the mains
and control cables (item 1 in Fig. 10).
NOTICE
The wall channel in Fig. 10 is shown
by way of example. An alternative wall
channel is shown as dashed lines
(item 2 in Fig. 10). For the subsequent
electrical installation work, we recom-
mend running the mains and control
cables from the left at the wall break-
through.
