    Moline vapor vacuum system

    I have a house where there is a Moline system with a condensinmg loop in the basement. The original vacuum main vents are missing and were replaced with standard main vents. Does anyone know where to get vacuum main vents?

    except

    you may not need a vacuum vent -- they were really needed for old coal-fired units, and aren't so necessary (if at all!) on oil/gas. You do have Dan's book, don't you?

    Vacum Vents

    Hoffman does not recommend use of the #76 vent with newer furnaces. If you're using coal it's OK. Contact Hoffman for more information.
