1.2 IMPORTANT INFORMATION

• Installation, heat–up test and user training must be performed by the technician trained by
producer. The technician must fill the protocol about the installation of the boiler.
• By gasification of wood it comes to creation of tar and condensates (acids) in the fuel tank.
Due to this there must be a mixing device installed behind the boiler to keep the minimum
temperature of return water at 65 °C. The temperature of water in the boiler during its opera-
tion must be within the range of 80 – 90 °C.
• The boiler must not be permanently operated within the output lower than 50 %.
• If the circuit pump is being used, its operation must be controlled by a separate thermostat
to ensure the prescribed minimum temperature of the return water.
• Ecological boiler operation is related to its nominal output.
• It is recommended to install the boiler together with the accumulation tank and mixing de-
vice. This ensures the fuel saving of 20 – 30 % and longer lifetime of the boiler and chimney.
• If it is not possible to connect the boiler to the accumulation tank, it should be connected
with at least one equalization tank with the volume of approximately 25 l / 1 kW of the boil-
er´s output.
• By the operation with lower output (summer operation and D.H.W. preparation) it is neces-
sary to heat the boiler up every day.
• Only the dry fuel of 12 – 20 % moisture can be used (by the higher moisture of fuel is the
boiler output decreased and its consumption increased).
• Due to the economical operation and correct functionality it necessary to choose an appro-
priate boiler output. The nominal output of the boiler has to be adequate to the temperature
loss of the heated object.
WARNING! When the boiler works in PELLET mode, the primary and secondary air
flaps must be closed.
ATTENTION: The boiler must be used only for the purpose that it is intended for and
only in the way given in this manual.
The warranty for the boiler is not valid:
• if it is not operated with the prescribed fuel.
• if no mixing device Regumat ATTACK–OVENTROP is installed in the system to ensure the re-
turn water temperature of at least 65 °C during the boiler operation.
• if no functional thermostatic valve is installed on the aftercooling circuit (WATTS STS20) of
the boiler, connected to the cold water inlet.
This device is not supposed to be used by persons (including children) with physical, sensual or
mental disability or insufficient experience due to which they are not able to use the device in a
safe way without being supervised or instructed about the boiler operation by the person re-
sponsible for their safety. Do not to allow the children to play with the device.
If the power supply cable is damaged, it must be replaced with a special cable available by
producer or by a service technician!
