2 Safety information
3.3 Installation room
Structural specifications
–
The boiler may only be installed in a dry, frost-free
room; the permissible room temperature is 5 to
30°C.
–
The boiler may only be used on a non-com-
bustible surface with sufficient load-bearing capa-
city.
–
Observe spacing to combustible materials (regio-
nal regulations).
–
Note the installation dimensions to ensure suf-
ficient space is provided (e.g. for service and
maintenance work).
–
For normative requirements, see ÖNORM H 5170
and directive TRVB 118 H.
Fire extinguishers
–
Austria: A 6 kg ABC powder extinguisher is spe-
cified as the minimum requirement. Install it out-
side the boiler room in an easily visible and
quickly accessible place.
–
Germany, Switzerland: In private homes, no fire
extinguisher is required for heating systems.
However, having a fire extinguisher is recommen-
ded.
Keep escape routes clear
–
Under staircases, on escape routes and in uncon-
verted attics, the installation of fireplaces is inad-
missible.
3.4 Chimney, flue gas pipe
Chimney cross-section and chimney height
The necessary cross-section depends on the nominal
output of the heating system and the effective chim-
ney height (at least 6.5 m). We recommend that you
have the chimney calculations performed by qualified
personnel.
As a general rule of thumb:
For nominal boiler outputs of up to 25 kW, select
a chimney diameter of 13 cm.
Chimney execution
–
The chimney must be resistant to moisture. Use
fire brick or stainless steel.
–
The chimney must conduct away the flue gases
reliably at all times.
Connect the chimney condensate drain to the
sewage system
–
Connect the condensate drain line of the chimney
to the domestic sewage system (to drain con-
densate, rainwater).
–
Use DN 25 diameter pipe, install trap.
Provide each boiler with its own chimney
–
The boiler and the chimney must be coordinated.
This is the only way to ensure the proper func-
tioning of the heating system and the correct
discharge of the flue gases.
–
If there is only one chimney available for two boi-
lers, there is a risk (considering the different ope-
rating states of the boilers - full load/partial load)
of poor coordination. This can lead to problems
(e.g. the flue gas has too little energy during the
ascent, and does not lift off sufficiently from the
chimney mouth, ...odour pollution by flue gases).
–
Chimneys with just one device are more reliable
and safer than chimneys with multiple devices.
Do not connect a gas boiler and blower boiler to
the same chimney
Do not connect a wood-burning stove and
blower boiler to the same chimney
–
A wood-burning stove typically requires a larger
chimney diameter than the blower boiler.
–
Acoustic disturbance from the blower boiler may
be possible in the living room (by the wood-
burning stove).
–
Unnecessary risk due to gas leakage, e.g. if the
blower boiler is defective.
