I have noticed water dripping from beneath the boiler - and I presume its condensate as there is no condensate pipework fitted. All I can see beneath the boiler is a brass outlet - is this the prv terminal and should there be pipe work connected to the prv? The manual shows a plastic outlet for the condensate but this isnt obvious - any ideas as I need to connect the condensate pipe to the drain(not done by plumber).Be grateful for any pointers
