    Issue with PIR Lght.

    Hi, Mounted one of this on the wall outside in the garden, couple of feet away from the boiler flu. The trouble is, it comes on in the evenings whenever the boiler spews out. Going back to shift it further away from the flu. Any other suggestions to get around it? Thanks!
