When the pellet boiler is placed, it must be levelled with support feet (horizontal positioning).
ATTENTION
Smoke gas discharge MUST NOT BE CONNECTED TO:
• Flue pipe, used by other combustion devices (boilers, stoves, fireplaces etc.);
• Air extraction systems (hoods, air extraction fans etc.).
ATTENTION
Installation of draught closing valves is prohibited!
Flue connection Ø 80 mm from pellet boiler to flue pipe should be:
• no more than 5 m long (in case of longer connection, dimension of connection pipe must
increase to Ø 130 mm);
• each 90° joint requires a 1 m shorter flue connection;
• each joint must be fitted with doors for cleaning;
• connections between pipes must be sealed.
ATTENTION
If there is too much resistance in extraction system (many joints, improper end fitting,
bottlenecks etc.), extraction of smoke gases is not provided for. Therefore, connection pipes
and joints must be increased to a greater dimension – Ø 130 mm. If the flue does not ensure
appropriate extraction of smoke gases, it can also come do improper operation and,
consequently, to alarm from boiler Biodom 33. It is advisable that the flue is inspected by an
expert before installing boiler Biodom 33.
Smoke gases extraction system from pellet boiler functions on the basis of negative pressure in the
boiler and barely perceivable pressure in flue connection pipe Ø 80 mm. It is very important that the
smoke gases extraction is sealed.
Layout and structure of the space, where the flue is installed, needs to be analyzed. If it passes
through walls and/or roof, it must be properly installed in accordance with fire prevention safety
standards.
Ensure that there is enough air for proper combustion in the space, where the pellet boiler is
installed. If boiler Biodom 33 lacks oxygen/air, the boiler displays an alarm. External supply or intake
of external air requires a pipe with a diameter of at least 110 mm with maximum length of 10 m. Each
90° joint requires a deduction of 1 m in line length. If the air supply is longer, diameter of air intake
pipe must be increased.
In case of a grid on the facade, draught opening must be 100 cm² or larger.
