    wrong area for info

    can you please repost in the "strictly steam" area. you will get more steam related replies there. in answer to your question however, the hoffman 76 is a vacuum vent, however  there may be other reasons why maintaining a vacuum is not a good idea in  todays modern-fueled steam systems.-nbc
