Hi, i've just had a combi boiler fitted, vaillant 824, do i still need the air vent from previous boiler or can i patch this up? Another quick question is i've noticed a noise coming from the boiler i didn't hear at first, only seems to be when central heating is on, it seems to be around heat exchange area when it's built up a bit of heat there's a metallic [expanding]clonking sound [not loud] is this normal? I thought it was a couple of hanging pans in the kitchen at first, just if any light can be shed before i mention it to the fitter it would be handy.Cheers
