01 GENERAL NOTES
• This planning document contains product-
specific information on the installation and use of
Biotech pellet heating systems. It does not replace
compliance with country-specific regulations, laws,
standards, etc. These must be observed in addition.
These must be complied with in addition.
• The pellet boiler described in these instructions has
been tested in accordance with EN303-5.
• Only use the fuels specified by us - wood pellets
in accordance with EN ISO17225-2:2014 class
A1 (Ø 6 mm). This is the only way to ensure low-
emission, economical and trouble-free operation
of your pellet boiler. Non-observance will result in
the loss of the warranty. Biotech accepts no liability
whatsoever for damage caused by the use of fuel
that does not have this certification.
• Bei einer Pelletheizung mit einer Nennleistung
von mehr als 50 kW muss der Puerspeicher so
dimensioniert sein, dass bei der Tagesbefüllung
des Puerspeichers genügend Betriebswasser für
ca. 1,5 Stunden im Puerspeicher vorhanden ist.
Mindestens zweimal täglich schaltet sich die Anlage
zur Reinigung (Wärmetauscher- und Rostreinigung)
automatisch ab. Abhängig von der Restmenge an
Pellets im Vorratsbehälter sowie dessen Größe und
der Anlagenleistung kann der Vorgang (Ausbrennen
/ Befüllen / Zünden) bis zum Erreichen der
Nennlast (100% Leistung) bis zu 1,5 Stunden dauern
- in dieser Zeit wird der Puer nicht beladen.
• For long burner running times, to reduce start-stop
emissions and to reduce wear, the boilers should
be equipped with buer storage, thermosiphon
buer storage or combi storage. In practice,
buer sizes between 40 and 75 litres/kW have
proved successful. Observe the country-specific
requirements for buer storage tanks. Operation
of the system is only permissible if it can be
guaranteed that 50% of the nominal boiler heat
output is drawn o for a period of at least 2 hours
per system start. The firing capacity modulates in
a capacity range of 30% to 100% of the nominal
capacity. If possible, the units should be operated
in the medium and upper output range (adapted
to the respective heat demand) in order to avoid
unnecessary emissions in low-load operation.
• After a maximum of 12 hours of continuous
operation, the units shut down to carry out a
cleaning cycle or to fill the intermediate container
with pellets. Depending on the type of unit, it then
takes up to 45 minutes until the nominal output of
the system is available again. This must be taken
into account in the power requirement calculation.
Please also note that poor fuel quality can reduce
the heating time to less than 12 hours.
• When planning biomass systems, it must
be ensured that noise is generated by the
corresponding mechanics or by drives such as
ignition fans and vacuum turbines. Appropriate
insulation measures must be taken on site. It
is strongly advised not to locate heating or
installation rooms directly under living and/or
sleeping areas.
• The assembly, installation and commissioning
(adjustment) of our pellet heating systems may only
be carried out by our customer service or by an
authorised specialist company certified by us.
• Carry out the cleaning work recommended by
us in the instructions at regular intervals on your
pellet boiler, the discharge system and the storage
room. This will not only ensure the functional
reliability of the system, but also the ecient and
low-emission operation of the system. You can
achieve the best care for your pellets heating
system by concluding a maintenance contract. The
specified cleaning and maintenance intervals must
be observed. Please note that there is no warranty
claim for damage caused by non-compliance with
the maintenance instructions. Biotech accepts no
liability whatsoever for damage caused by non-
compliance with the cleaning and maintenance
intervals.
• For legionella protection, the generally applicable
rules of heating technology must be observed.
• The regulations according to Ö-Norm M 7136
(transport and storage logistics) and M 7137, or VDI
guideline 3464, or country-specific requirements
for pellet storage must be observed.
ATTENTION!
The mandatory maintenance of the unit must
be carried out at least once a year, at the latest,
however, after reaching 1500 operating hours in
the performance range of 80 - 100 % by authorised
specialist personnel.
