Now remove all of the material in the centre using the most
suitable tools for the material you're cutting. We do not
recommend that you cut through to the outside in one go.
Cut away material on the inside of the house first and then
move outside to cut the remainder of the hole. Try to keep the
hole within the outlined area otherwise it will be too big.
We recommend using one of the tunnel extenders to make
sure you have a clear path through the wall. Once this is the
case, clear away any dust and debris.
To extend the Cat Flap's tunnel through to the outside wall
you need to use the tunnel extender accessories to make up
this length. To calculate how many extenders you will need
for the tunnel to reach the outside please go to page 23. It
is important to remember that the end has to stick out by at
least 10mm (3/ 8 ") for the external frame to rest on.
Stack the tunnel extenders together and then attach them
to the end of the Cat Flap's tunnel, using weatherproof tape
between each join to hold them together. Do not glue the
tunnel extenders or Cat Flap together.
From the inside of the house, feed the extended tunnel into
the hole in the wall until the Cat Flap is flush against the wall.
If no adjustment to the hole shape or size is needed then you
are at the point where you can attach the Cat Flap to the
inside of the house.
The Cat Flap can be secured directly to your inside wall. To
access the screw holes needed, you have to unscrew the front
frame from the tunnel. To do this, first remove the battery
cover and screw covers, then unscrew the four screws and
lastly pull the tunnel and front frame apart.
Now locate the 4 screw holes, they are the larger holes in the
corners of the Cat Flap. Mark the hole positions using a sharp
pencil.
