Buderus & Creosote

Buderus18

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
