Buderus & Creosote

in Domestic Hot Water
My Buderus Logano wood burning boiler connected to my oil fired baseboard heat system easily heats my 2400 sq. ft. home but, I’m producing a lot of liquid creosote which worries me! How do I get help, contact Buderus or “Joe at Buderus”?

    Are you burning dry seasoned wood? Could be a little over sized where it is smoldering too much, wood is generally meant to burn hot.

    from manual--- Too much condensate forms in the
    fuel space of the boiler, black liquid leaks out of the fuel filler door =

    1- Boiler output too high Insert less fuel.
    Check possible heat loss in the object

    2- Incorrect or too-humid fuel Use prescribed fuel with prescribed humidity

    3- Low boiler water temperature Check/increase minimum boiler
    water temperature and ensure a minimum
    temperature of 131 °F for the return due to a suitable setting of the mixing valve

    and 3.1 Wood firing
    Prescribed is split and dried wood with a diameter of
    6 inches or less and a maximum wood humidity of 20 %.
    Only use dry, natural, chunky wood. With a wood humidity
    of more than 20 %, the boiler output is reduced. In addition,
    there can be increased tar formation, which reduces
    the life span of the boiler. The specified output values and
    the trouble-free function of the boiler can only be guaranteed
    with a maximum wood humidity of up to 20 %

    Tab. 5 Maximum length of split or chipped wood
    model length
    27 -------15 ¼ inches
    35-------- 19 ¼ inches
    40-------- 27 ¼ inches

    plus I believe there is to be a minimum 2" space from the top of the wood to the top of the chamber and refueling too often can be a problem
