Minimum water level adjustment steam heating

How do I reset the minimum water level in the glass tube on my steam boiler. Currently it's too high being too close to the maximum level such that in the normal fluctuations up and down during running sometimes it hits the low point and refills and ends up overfilling. I want to lower the minimum point (it will still be above the safe minimum however). Please advise.
I have a Weil-McClain boiler with an automatic water feed.

    Perhaps repost on The Wall. I don't have an answer for you.

    George-

    The automatic water feeder is set up at installation to maintain the water level required by the manufacturer. If you are getting a flooded boiler, chances are that it's either the feeder control or your wet returns are plugged. A plugged return causes the condensate to return too slowly-which in turn causes the feeder to add make-up water. Eventually the condensate does return, overfilling the system. Hope this helps.
