Hi guys fitting my first boiler (gas safe) and sooooo silly question time. BTW only registered through a company yesterday pm. With regards to air vents on boiler pipework with a pressurised system.... are they necessary. the plumber I worked for alwys put them in but with the layout of the pipe work unless i run the flow and return behind the boiler (worcester greenstar 15ri heat only) it will mean a 750mm dead leg to get the aav above the boiler.
thanks
