VENTILATION THE RIGHT WAY

►

Apply the plaster scrim M-WRG-PG (item 4 in Fig. 20 on page 16) to the wall box and the

solid wall.

►

Cover the flexible pipes with plaster scrim.

NOTE

Applying plaster scrim will prevent cracks subsequently forming in the plaster.

►

Plaster the solid wall.

7.14

Aligning the wall box on the outside

►

Fill the gaps between the wall box and wall

breakthrough all around and continuously

with expanding foam or using another insu-

lating material.

—

If the solid wall is

less than

36.5 cm thick:

► Use a Styrofoam saw to cut off the

excess wall box (item 1 in Fig. 21 and

Fig. 22) and filler piece, if necessary

(item 2 in Fig. 22), so that they are

flush with the solid wall or any insula-

tion.

—

If the solid wall is

more than

36.5 cm thick:

► Compensate for thicker walls with

continuous pipes. For walls that are

60 cm thick or more, you will need 100

cm long supply and exhaust air pipes

(M-WRG-LR 100, part no. 5580).

NOTE

The pipes must be continuous. Pipes that have

been joined must not be used as there is a risk of

allowing condensation to penetrate the masonry.
