Thanks Dobber!

In the words of H.J. Simpson.. "doh"

I guess in my tirade of four-letter words last night about 10pm I "failed to see what was to be seen"

Thanks again,

    Can somebody tell me what the proper tool to open a Wirsbo radiant manifold end cap purging valve is?

    At first I thought it was the same as a key for venting a radiator.. Nope.

    Then I thought perhaps a socket would do.. metric or SAE.. nope.

    I am thinking maybe I need a stop key wrench? Any clue as to what size (1/4?)

    The wrench is on the other side of the screw on cap.

    Good Luck
