Operating fault
The cause
Solution
Burned safety fuses
This inspection may be performed only by an
authorized technician: check the status of each
fuse and, if necessary, replace it with a new one
(Caution: Safety fuses F1, F2, F3 and F4 have a
fast activation);
Flame has a purple
colour and at the outlet
to the chimney can be
observed smoke
Fuel of poor quality
It is recommended to replace the fuel, the moisture
is higher than recommended - see chap. 2 -
Prescribed fuel.
Setting of incorrect operating
parameters
Modify the the operating parameters - this
operation may be performed only by an authorized
and trained technician;
Fuel ignition was
successful, but the unit
did not reach a stable
operating mode
Incorrect placement of photoreceptor
Change ( slightly rotate or rotate along the axis)
the position of the photosensor
Photosensor is dirty on the surface
Carefully clean the transparent part of the
photosensor - Do not use solvents
Photosensor is functionless- its working
surface is damaged and burned areas
can be observed
Replace the photosensor - this operation may be
performed only by an authorized technician
Burner operation is not
stable
Malfunction of photosensor
Check the status and function of the photoresensor
The operating parameters of the control
module were changed
Check the position of the potentiometer of heat
output (VIADRUS HERCULES Green Eco Therm
XS)
Check the degree of operational heat output of the
control module of burner (VIADRUS HERCULES
Green Eco Therm XJ);
Check the values of operational parameters of the
control module of burner- this operation may be
performed only by an authorized technician
Warming of knee of
burner and activation of
temperature sensor
against penetration of
burning fuel
Insufficient chimney draft or deposition
of dirt in the knee of burner
Clean up the deposits of dirt in the knee and in the
combustion chamber of burner or clean the boiler
drum. A possible solution is to also the installation
of an additional exhaust fan * - is performed by an
authorized technician;
It is necessary to restart the burner.
Increased temperature
displayed on the return
temperature label of the
liquid crystal
Insufficient chimney draft, clogged flue
path.
Clean up the deposits of dirt in the knee and in the
combustion chamber of burner or clean the boiler
drum. A possible solution is to also the installation
of an additional exhaust fan * - is performed by an
authorized technician;
Activation of reversible
heat label, located on
the knee of burner
High temperature of the knee of burner
because of an insufficient chimney draft
Clean up the deposits of dirt in the knee and in the
combustion chamber of burner or clean the boiler
drum. A possible solution is to also the installation
of an additional exhaust fan * - is performed by an
authorized technician;
Unburned fuel in an
ashtray
Inefficient process of combustion of fuel Modify the operational parameters of the burner –
has to be performed by an authorized technician;
In the combustion
chamber of the burner is
deposited ash
(especially on the grate)
Ash content in fuel is higher than the
recommended values
Exchange the fuel – see chap. 2 – Prescribed fuel
The burner operates at heat output
which is higher than the nominal values
Reduce the degrees of the heat output of burner
High temperature of flue
gas
Clogged boiler drum, flue gas ways and
smoke flue
Clean the boiler drum, flue gas ways and smoke
flue
