Chimney draft:
If the chimney draft is exceeding 15 Pa, a draft stabilizer should be mounted in the chimney.
WARNING!
By chimney temperatue less than 180°C at rated output, you should be aware that smoke dose not
condense in the chimney as it gives soot. At particularly low smoke temperature it may be necessary to
put a ceramic or stainless steel sleeve in the chimney.
