Locate airbrick to be replaced.
Starting at a corner, drill through the mortar with the power drill, drill the holes along the mortar surrounding the airbrick.
Grind out the mortar around the airbrick or break out with hammer and chisel.
Once the airbrick is loose, remove from the wall and ensure that there is no mortar obstructing the corners. Clean aperture with brush.
As certain the front of the brick (marked Front) and ensure it’s the correct way up (marked with an arrow up). This should be facing to the front, the spacers are situated on the bottom. Mix a mortar of sand, cement and PVA, wet the aperture with water, insert the Anti-Flood Airbrick and point around ensuring that the full bed of mortar is achieved across the depth of the brick (use the lip on the rear edge of the brick to ensure mortar is installed to the correct depth) paying attention to the type of mortar and the style of pointing. The face of the brick should sit flush with the wall.

NOTE: It is absolutely imperative that the airbrick is installed with the utmost care, ensuring that all pointing is faultless. Remember, if water can get in, it will.
Remove film sticker to complete the installation.

NOTE: Ensure that the mortar is completely dry before the screw front face of the airbrick is removed for maintenance inspection, allow minimum seven days to fully cure.

NOTE: Double (or triple) airbricks can be replaced with two (or three) airbrick replacements placed one on top of the other and aligned with the mortar joints of the two (or three) courses of bricks.
The 8mm lip on the bottom rear edge of the brick can be removed using a hack saw to ensure the top brick sits comfortably above the lower brick.
