semi-concealed in ground gas box

[Matt0029]

Does a semi-concealed in ground gas box need to be 150mm from an air brick in a building? Sure I read this somewhere not sure if it was for medium pressure installations though. Thanks for any advice.

hope this helps

The box is partly buried at the foot of the house wall at a depth shown by the level indicator marked on the box. This will ensure that the installation protrudes approximately 250mm above ground level at the wall, sloping to 160mm at the front of the box, thereby preventing the ingress of water.

To avoid any restriction of air flow, it must not obstruct air bricks and should be sited at least 150mm from any other item / box.

Thank you. So it states the box needs to be 150mm from another box. Not an air brick? Must of read it wrong. Thanks. What's its classification of an item though?
