Fixing the wall box
►
Fix the wall box (item 1 in Fig. 14) in posi-
tion in the wall breakthrough using wedges
(item 2 in Fig. 14).
►
Use the spirit level (item 3 in Fig. 14) to
align the wall box so that it is perpendicular
and flush with the wall.
NOTE
►
Make sure that the wall box is perpendicu-
lar as this is the only way to ensure that any
condensation will be carried outside by the
2° pipe fall.
►
If you are using the filler piece, fix it in place
on the outer wall using wedges.
