Important: You use a burner
whose carbon footprint values
are approximately (СО = 100
ppm), which is 2.5 times lower
than the maximum allowed
limits for harmful emissions in
the EU Member States. Thus
you can reduce the amount of
harmful emission and contribute
to environment protection.
Important: For each of the
output modes the optimal fan
setting is tweaked by using gas
analyzer to control the oxygen
amount registered by the device
(within the range 8% ÷ 10%, and
for the lower modes up to 16%).
The specific setting depends
also on the internal resistance of
the boiler combustion chamber
on which the burner has been
installed as well as on the
chimney draught. Therefore it is
not possible to provide here the
exact value for the fan output
and it must be entered by a
competent installer or service
technician using gas analyzer
period is
3240
grams (
900 sec
). We
then divide
3240
by
900
and get
3.6
grams of pellets per 1 second. Repeat
the measurement in order to obtain
conclusive results.
11.2. Burner output adjustment.
In the burner output settings menu you
can adjust the running time of the main
auger (
Feed
); main running interval
(
Cycle
) and fan output (
Fan
).
Example for Pell 25 model
: we select

Cycle
=

sec.
The heating value
of your fuel is
4.8kWh/kg
. (manufacturers
indicate the heating value of the fuel on
the packing – take it from there). We then
employ the following formula to calculate
the number of seconds for setting the
operation of the main auger for these
20
sec:
t
FEED
= 25 000 / (4,8
x
180
x
3,6)
hence
t
FEED
= 8 сек.,
where
25,000
is the desired output of the
burner in Watts (W),
4.8
is the heating
value of the fuel in kWh/kg,
180
is the
number of burning cycles per 1 hour,
3.6
is the amount of pellets in grams fed
by the auger per 1 second. This way the
output mode can be changed and instead
the number
25,000 – 25kW
, we input
the desired kilowatts
(40 kW=400
0
0 W, 70
kW=700
0
0 W etc.)
.
Take also note of the fuel heating value
which would change the value for the
feed and the burner output.
Using the above procedure, you can set
any of the three output modes of the
burner.
