Vaillan Ecotec 837 - where is the AAV! Automatic air valve?

ok im not fam. with the particular boiler but this much i know for def..the auto air valve will always be at the highest point or the contrapction and will probably involve removing the front casiing and climbing a steps to inspect the top.loosen it carefully if you find it until water tricles them tighen gently til water stops.them are notorious for bitching.

The AAV is part of the pump, it is situated on top of the black plastic part of the pump rear, to the right hand side.
