1.2.6 Chimney connection / chimney system
EN 303-5 specifies that the entire flue gas system must be designed to
prevent, wherever possible, damage caused by seepage, insufficient
feed pressure and condensation.
It should be noted here that flue gas temperatures of less than 160 K
above room temperature can occur within the permitted operating range
of the boiler.
The flue gas temperatures (when cleaned) and the additional flue gas
values can be found in the technical specification sheets.
À
See “Boiler data for constructing the flue gas system”
Establish the connection to the chimney via the shortest path, ascending
as much under 30 – 45° as possible Insulate the connecting piece.
The entire flue gas system (chimney and connection) must be calculated
as per ÖNORM / DIN EN 13384-1 or prior standards ÖNORM M 7515 /
DIN 4705-1.
Local and other legal regulations also apply.
The chimney must be approved by a smoke trap sweeper or chimney
sweeper.
As per TRVB H 118 (only in Austria) an explosion flap must be
installed in the flue pipe or in the chimney.
Draught limiter
We recommend that you install a draught limiter 1
Install the draught limiter directly under the mouth of the flue line,
as there is always low pressure here!
