Explanation:
The term “low-rise building” is explained in building codes of the
Bundesländer (states) under the paragraph titled “Terms.”
According to the model building code, they are referred to as
buildings in which the floor of any story where it is possible to have
installation rooms, does not lie more than 7 meters above the
ground surface at any point.

2.6.3 Cleaning und test openings
Flue gas systems as defined by the model building code and the
state building code must be easy and safe to clean. In addition to
that, it must be possible to test their profile and gas tightness.
The number, the condition, and the required dimensions should be
coordinated with the competent local chimney sweep. These
conform to the assessment criteria that are agreed upon with the
building supervisory bodies.
They include the following excerpts:
The lower cleaning aperture of a flue gas pipe should be located
- In the vertical part of the flue gas pipe directly above the flue
gas deflection or to the side
- In the horizontal part of the flue gas pipe at a maximum of
0.3 meters away from the deflection to the vertical part or
- In the horizontal part of the flue gas pipe on the front side at a
maximum of 1 meter away from the deflection to the vertical
part, if there is no deflection in between.
Flue gas pipes that cannot be cleaned through the mouth
must have an additional (upper) cleaning aperture that is
- up to 5 meters below the mouth of the flue gas pipe or
- up to 15 meters below the mouth of the flue gas pipe if only
gas furnaces are installed and the vertical section of the
flue gas pipe is not routed (extended) at more than max.
one x max. 30° diagonally
- For flue gas pipes that are shorter than 5m or 15 meters,
the lower cleaning aperture alone is sufficient as long as
there is a platform of at least 1 meter x 1 meter.
For flue gas pipes that are connected to furnaces, a cleaning aperture is generally
sufficient if,
- The vertical section of the flue gas pipe is no longer than 15
meters and is routed (extended) at max. one x max. 30°
diagonally
-
The cleaning aperture in the horizontal section is at max.
0.3 meters away from the vertical section
- T he horizontal section in front of the cleaning aperture is
not longer than 1.5 meters and does not contain more
than 2 elbows
- All deflections (including from the horizontal to the vertical
section of the flue gas pipe) are done through elbows with
a bend radius that is larger or equivalent to the diameter
of the gas pipe
- The diameter of the gas pipe is not more than 150 mm.
Make sure you can test and clean the cross-section between the
flue gas pipe and the duct (rear ventilation) . The cross-section is
necessary for reliable operation of the heating system.
C
leaning apertures in the ducts must be at least 100 mm
wide and 180 mm high. The width can be set at 90 mm if
the height is at least 240 mm.

=- Gas appliance (Fan in front of the burner) with flue gas
system that draws the combustion air from outdoors via a
closed system (room air independent gas furnaces).
- Gas furnaces with combustion air supply and flue gas
outlet vertically above the roof; the mouths are located
close together in the same pressure range.
