VENTILATION THE RIGHT WAY
V E N T I L AT I O N & H E AT R E C O V E R Y
NOTE
► Be sure to align the ventilation pipes with a 2° drop from the internal wall to the
external wall. This will allow condensate in the ventilation pipes to drain to the outside.
► Use the spirit level to align the drilling template for the outer wall terminal.
10.6 Fixing the drilling template for the outer wall terminal
— Fixing the drilling template for outer wall terminal M-WRG-ESR:
► Fix the drilling template to the external wall with adhesive tape.
— Fixing the drilling template for outer wall terminal M-WRG-ES and M-WRG-ESG/AP:
► Drill the holes for the outer wall terminal (depending on the outer wall
terminal, see also the “Outer wall terminals M-WRG-ES...” installation manual,
part no. 5300-20-01).
► Fix the drilling template in place with the dowels and screws provided.
► Check the excess length between the ventilation pipes and the external wall with reference
to the following table (depending on the outer wall terminal, see also the “Outer wall termi-
nals M-WRG-ES...” installation manual, part no. 5300-20-01):
Outer wall terminal Excess
Stainless steel pod, M-WRG-ES 5 - 10 mm from the plastered external wall
Stainless steel pipe set,
M-WRG-ESR
25 - 30 mm from the plastered external wall
Stainless steel louvred design
(surface-mount) M-WRG-ESG/AP
5 - 10 mm from the plastered external wall
Table 3: Excess length of the ventilation pipes from the external wall
► Correct the excess, if necessary, by moving the ventilation pipe.
10.7 Fixing ventilation pipes and filling gaps with foam
► Spray expanding foam through the
recesses (item 1 in Fig. 16) in the drilling
templates on the internal and external
walls in order to provisionally fix the venti -
lation pipes.
► Check the position of the ventilation pipes
again.
NOTE
► Be sure to align the ventilation pipes
with a 2° drop from the internal wall
to the external wall. This will allow
condensate in the ventilation pipes to
drain to the outside.
► Wait until the expanding foam has cured.
► Remove the drilling templates from the internal and external walls.
