FITTING THE SEMI-RECESSED FAN SPACER
1
In cases where there is insufficient room to
recess the fan unit into the wall the fan spacer will
have to be fitted. This spacer mounts the fan partially
out of the wall so that the spigot does not protrude
into the cavity.
2
Place the spacer against the wall, ensuring it is
correctly aligned with the flue duct and mark the
position of the four fixing holes on the wall (See
Figure
7
) Drill and plug the wall at these positions.
Check that the spacer is the correct way up and fix it
to the wall. The spacer is the correct way up when
the internal box section with two holes is at the
bottom.
3
Remove the front cover from the fan unit and
withdraw the inner fan chassis, as previously
described. Remove the three large screws from the
top and bottom of the fan box and discard.
4
Cut a slit in the grommet at the rear of the fan unit (not the side grommet) and feed
through the power cable. Push the fan unit into the spacer and secure in place using the
three self-tapping screws and washers screws provided. The self tapping screws should
pass through the bushes from which the large screws were removed.
5
Fit the gasket, connect the power cable and refit the fan chassis as previously described.
6
Seal the edges where the two boxes meet and where the spacer meets the wall with
silicon mastic.
