is made to ignite. In order not to clog
the burner with unburned pellets, the
amount of new pellets fed is halved with
each subsequent ignition attempt.
In addition, new pellets are only supplied
for the first 3 ignition attempts in terms
of 100%, 50% and 25% of the set amount.
When the set maximum number of
ignition attempts is exhausted, the
burner stops by displaying an ignition
failure message.
The parameters required to control the
loading with the first dose of pellets and
their ignition are in the menu:
"Service
settings" -> "Settings combustion "->
"Fuel X"->"Ignition"
.
The parameters for detecting a lit
or extinguished fire are in the menu
"Service settings" -> "Fire detection"
.
The next phase of operation of the
burner are the
procedures for calmly
lighting the fire
.
If pellets and air supply for maximum
power start with an unstable flame and
a cold combustion chamber, the flame
can be suffocated or blown out. To
prevent this, first wait for the burning of
the first dose of pellets and then begin
a gradual increase in power from the
lowest power P1 to the greatest required
power, depending on the difference in
temperature (set temperature and water
temperature in the boiler ).
The setting of the combustion process
is done in the menu
"Service settings"
-> "Combustion setting" -> "Fuel X" ->
"Combustion"
.
The next step is combustion control.
The controller supports settings for
4 different powers. Three of these
The burner then goes into the
ignition
phase
.
The burner
ignition
procedure begins
with loading the first dose of pellets into
the combustion chamber. The ignition is
done with the help of an electric heater
and forced air from the burner fans.
The
ignition procedure
performed
after loading the first dose with pellets
consists of three stages. During the
first stage, only the electric heater
without the fan works in order to reach
the required ignition temperature
faster. During the next two stages, air
is supplied to the combustion chamber
simultaneously with the operation of
the heater, thanks to which the heat of
the heater is transferred to the pellets
and the necessary oxygen is delivered to
ignite the fuel. Usually during Stage 2 the
fan is set with more low speed so as not
to cool the flame, and after a more stable
ignition of the fire, the amount of air can
increase, which can happen during Stage
3.
From the
"Service settings"
menu ->
"Service settings" combustion "->"Fuel
X"->"Ignition"
sets the maximum
duration of each stage of ignition, as well
as the speed of the main and chimney
fan. When the photo sensor measuring
the illuminance of the fire detects that
the pellets are ignited, the heater is
stopped and a combustion procedure is
started, which aims to stabilize the fire
while the combustion chamber is not yet
hot enough.
If the pellets do not ignite within the set
time, the burner is loaded with a new
portion of pellets and a new attempt
