Pressure relief value pipe location on 1st floor

[benjiman]

Afternoon,

Got an existing boiler installation on a 1st floor flat in the kitchen.

The pressure relief valve pipe comes out and terminates bent back towards the wall. The ground floor flat below has a window underneath about 2 ft below where the pipe exits the 1st floor property.

Do regs allow such an install? Or does it need to be moved so it comes down towards ground level?

it is advisable not to have it terminating above openable window or a door due to possibility of scalding
