3 Technical requirements
Execution of the flue gas pipe
–
Run the flue gas pipe towards the chimney in
a short and rising direction, with as few chan-
ges of direction as possible.
–
Change direction in the form of aerodynamically
favourable arcs, do not build kinks.
–
The diameter of the flue gas pipe to the chimney
may be enlarged if required, but may not be redu-
ced.
–
Place the inlet of the flue gas pipe in the chimney
just below the ceiling.
–
The flue gas pipe must be tight. Seal seal-less
flue gas pipes on site with heat-resistant silicone.
Insulate flue gas pipe
–
Insulate the flue gas pipe continuously from the
boiler to the chimney.
–
Recommended insulation thickness: 50 mm rock-
wool.
–
Serves to prevent temperature loss and prevents
the consequential formation of condensation.
Cleaning opening in the flue gas pipe
–
To clean the flue gas pipe (e.g. removal of accu-
mulated flue ash) there must be an easily acces-
sible cleaning opening.
–
Recommendation: Coordinate the number and
placement of the cleaning openings with the chim-
ney sweep.
Opening for emissions measurement in the flue
gas pipe
Make an opening (hole) in the flue gas pipe to per-
form the prescribed emission measurement
> 30
Minimum draught requirement for boiler: 5 Pa
A draught stabiliser must be fitted if the specified
draught of 15 Pa is exceeded.
Recommended chimney diameter
For all maxi
mus
L Boilers (150 to 300 kW output), a
chimney diameter of 25 cm is recommended.
Install explosion flap

i
Before longer horizontal pipe sections
(L>20xD) and at the high point before drop-
ping down the flue gas pipe, an explosion flap
must be installed, independent of the boiler
output.
From 100 kW boiler output, an explosion flap is requi-
red in the flue gas pipe. This avoids damage to the
boiler or the flue gas system even when deflagrations
occur.
3.5 Supply air in the installation room
The following applies for Austria (in accordance with
H 5170):
–
For the supply air, 2 cm² per kW thermal output of
the fuel, but allow at least 200 cm² free cross-sec-
tion. (Fuel heat capacity = boiler capacity / effi-
ciency)
–
For the exhaust air, allow at least 180 cm² free
cross-section up to 100 kW nominal heat and an
additional 1 cm² free cross-section for every fur-
ther kW.
i
Calculate at least a further 20 % for wire mesh
in the aeration cross-section.
The following applies for Germany (according to spe-
cimen firing ordinance):
–
For heating appliances with a nominal output of
up to 35 kW, a combustion air opening of at least
150 cm² or 2 x 75 cm² routed directly into the open
air must be provided.
–
Alternatively, a door/window leading outside and
a room content of at least 4 m³/kW nominal heat
output are suitable. If the Heizraum does not abut
onto an outside wall, combustion air supply via
connecting rooms is possible. Here, the com-
bustion air is supplied via a sufficiently dimen-
sioned adjacent room which abuts onto an
outside wall.
–
From 35 to 50 kW, provide a free aeration cross-
section of at least 150 cm². From 50 kW upwards,
for aeration and ventilation, provide a minimum
free cross-section of 150 cm² for each, plus 2 cm²
per KW in excess of 50 kW.
i
Calculate at least a further 20 % for wire mesh
in the aeration cross-section.
