of the wall.
2. Check there are no buried pipes of cables in the wall or obstructions on
the outside e.g. Electricity, Gas, Water.
3. Mark on the wall the centre of the hole and drill right through.
4. Draw a circle on this centre to suit the wall duct.
5. Cut the hole. Do not cut right through the wall.
(The recommended method is to drill a series of holes, close together, around the
edge of the cutting line and remove the brick between the holes with a chisel.
Warning: eye protection must be worn).
6. Go outside and cut a hole in the outer wall, repeating the process described
above.
7. Fit the ducting.
