4. Safety, burner installation and commissioning
Safety and connection of the burner to the boiler
WARNING - Before starting the burner you must carefully read all the provisions of this
manual. At the same time you must observe all general safety regulations for work with
heating equipment resulting from the valid legislation.
• The premises where the equipment will be installed must comply with all fire protection regulations
in accordance with valid standards and laws.
• The equipment must be positioned in such a way to ensure access for cleaning and removal of
ashes not only from the burner, but also from the boiler, flue gas duct and chimney.
• The burner must be installed to the boiler over a sealing cord, soft Sibral sealing or another
insulation and sealing material to prevent flue gas from escaping along the burner to the boiler
room. Under one of the nuts with the use of which the burner is attached to the boiler a SPECIAL
SHEET-METAL PART - END SWITCH STOP
must be positioned. It is used to compress the
end switch that monitors the proper position of the burner on the boiler. This protective device
must not be omitted in any case as it is directly related to fire safety.
• The connection between the burner and the boiler must be properly tightened to prevent flue gas
from escaping to the boiler room.
• During the installation you must make sure that the pellets can freely fall through the hose to the
burner. The connections between the hose, burner and conveyor must also be properly tightened.
Design and technical measures for increasing safety
• The ignition and combustion process is controlled by the electronic control unit by means of the
flame sensor - photocell . If the sensor does not sufficiently see the flame during operation, it will
automatically put the burner out of operation.
• The electronic control unit senses the speed of the burner fan and at any problems of the fan it
automatically puts the burner out of operation.
• On the burner frame there is an
end switch and end switch
stop that does not make it possible to
start to burner if the burner is not properly fixed to the boiler (e.g. after cleaning of the burner).
If during normal operation of the burner the end switch gets disconnected, the burner will be
automatically put out of operation. If at the start after two attempts with the fuel supply and one
attempt without the fuel supply the pellets are not ignited, the burner will be automatically put out
of operation.
• If during normal operation of the burner the fuel bin runs out of pellets, the burner will try a new
start and subsequently will be put out of operation. After replenishing pellets in the fuel bin and
drawing pellets to the conveyor you can start the burner by merely turning off and on the burner
switch on the boiler panel.
• The flexible transparent hose between the burner and external conveyor is made of special material
that melts at high temperatures and the hose will change to a spring that will separate the burner
from the fuel bin.
