Roll the plastic vent sheets into a tube and

feed them from the inside into the holes

previously made. Ensure the tubes sit

flush to the interior wall.

Go outside and trim off the excess vent tube using a sharp knife,

keeping the edge as neat as possible.

Insert the indoor fixing ring from the

vent cover onto the indoor side of the

air vent. Then fold the external vent

cover in half. Attach the chains to each

side of the vent cover, before sliding

the cover outside through the vent

hole.

Expand the external cover, before tightly fixing the chains by

hooking onto the indoor fixing ring. This will hold the external

cover firmly in position. Repeat for the second vent.
