Notice: The data contained in the table “Dimensions flue gas systems” represent guide values.
An exact calculation for the flue gas duct must be made on-site.
* With 5 bends or more the feed pressure total at the combustion air/flue gas line is to be reduced by 30% for the
calculation.
With total pipe lengths exceeding 50 m, a separate calculation is necessary.
