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.
、
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.
Go outside and trim off the excess vent tube using a sharp knife,
keeping the edge as neat as possible.
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.
