Cat flap installation in a brick wall
Measure the height of your pet’s stomach off the floor. Mark the height of your pet’s stomach on your wall. This will be where you will place the bottom of the inside of the pet door, so your pet can walk through the pet door comfortably. If you have more than one pet that will be using the microchip pet flap, make sure that the smallest measurement from your pets’ stomachs to the floor is used. Make this mark where you want the center of the microchip pet door to be, horizontally, and also mark this on the inside frame of the cat flap.
Breaking through the wall for the cat flap installation
Use a hammer drill with the correct drill bit to drill through the wall to create a reference point. Drill around the pencil outline, overlapping the line by about 2mm or 5/64 Inches. A masonry drill bit should be used to drill through the entire wall. If you do not already own one, a breaker can be hired for a day to remove the bricks and tiles from both inside and outside. Use a tunnel extender to check if you have broken enough out, by passing it through the hole, both inside and outside. Any obstructions are bits that still need to be broken out.
Clear away any dust and debris that could work its way into the cat flap mechanism and you may need to add some cement if you have made the hole too big in places, to fill it in. A vacuum cleaner can be used close to the drill bit to remove the fine brick dust before it fills your room.
Fitting the cat flap into the wall
Now drill on the cat flap inside frame to the inside of the wall. This should be done by removing the button cover to the inside frame, by unscrewing the screws. Measure how many tunnel extenders you require to pass through the hole in the wall. The tunnel extenders should be fixed together with all weather tape and taped to the inside frame of the cat flap.Then the tunnel should extend into the inside and outside frames of the pet flap.
The tunnel and inside frame can be fixed to the wall by drilling the screw holes with a masonry drill bit and putting in wall plugs. The inside frame of the pet door can now be screwed in by hand. The outside frame of the pet flap can now be put in place and the holes can be drilled in the outside of the brick wall. This should be done just like the inside frame screws. The button cover can now be put back in place.
To finish, apply an all weather sealant between the tunnel and outside frame cover and between the outside frame cover and the wall.
