Adapting the boiler to combust another type of gas can be performed only by QUALIFIED SERVICE COMPANY. This
operation is not included in the warranty repairs.
In order to perform above mentioned operations check if:
•
the tightness of the gas system connections was checked after the boiler installation and it was confirmed with the signature
and the stamp of the installer,
•
the electrical installation was made in accordance with applicable regulations,
•
the correctness of connections between the boiler and the chimney was checked and confirmed by a qualified chimney
service.
2. Gas valve coils EV1-EV2,
3. Measuring point of inlet gas pressure,
4. Measuring point of outlet gas pressure,
5. A minimum pressure adjustment screw,
6. A maximum pressure adjustment screw

4.3. Boiler adjustment
Below described ways of regulation are applied only for replacement of the gas unit. All regulations must be based on the equipment
listed in Table 4.3.2.1.
4.3.1. Gas flow regulation in the boiler (without using the flue gas analyzer)
Before proceeding to adjustment, activate the service function of the boiler in the following way:
- set the mode: WINTER; p.5.3
- press the button twice
- on the display symbol flashes;
left field shows fan rotation speed and max symbol placed over it, right field show
C.H. temperature.
,
- in time to 5 seconds press the for 2 sec.; after service function activation the symbol stops flashing,
- using the ” you can turn on maximum fan speed (defined by parameter P05),
- using the button”-” you can turn on minimum fan speed (defined by parameter P04),
- service function is activated for 10 min. Earlier termination - pressing the reset button.
Regulation of boilers with power 20kW, 25kW and 35kW
Maximum power adjustment Minimum power adjustment
•
Set the maximum fan speed according to 4.3.1
Check the gas flow rate on the gas meter for compliance
with Table 4.3.2.1. If you need to change the gas flow
turn the screw - pos. 6 (
Fig. 4.2.1.).
•
Turn the screw to the left to increase the flow, turn the
screw to the right to decrease it. Set value of flow you
can read on the gas meter.
•
Set the minimum fan speed according to 4.3.1
•
During boiler operation measure the gas inlet pressure on the
measuring point ( item.3 Fig. 4.2.1.) The value of pressure
depending on the type of gas are given in Table 4.3.2.1,
•
Remove the cap from the measuring point number 5
( Fig.4.2.1.)
•
Using the adjusting screw number 5 ( Fig. 4.2.1) set the
minimum gas flow according to the values given in Table
4.3.2.1.
•
Turn the screw to the right to increase the flow, turn the screw to
the left to decrease it.
4.3.2. Adjustment of the boiler with a gas analyzer
Regulation of boilers with power 20kW, 25kW and 35kW
Maximum power adjustment Minimum power adjustment
•
Set the maximum fan speed according to 4.3.1
•
During boiler operation measure the gas inlet pressure
on the measuring point ( item.3 Fig. 4.2.1.) The value
of pressure depending on the type of gas are given in
Table 4.3.2.1,
•
Connect the flue gas analyzer
•
Using the adjusting screw number 6 ( Fig.4.2.1) set the
gas flow to obtain the required composition of the flue
gas listed in Table 4.3.2.1.
•
Set the minimum fan speed according to . 4.3.1
•
During boiler operation measure the gas inlet pressure on the
measuring point ( item.3 Fig. 4.2.1.) The value of pressure
depending on the type of gas are given in Table 4.3.2.1,
•
Connect the flue gas analyzer
•
Remove the cap from the measuring point number 5
( Fig.4.2.1.)
•
Using the adjusting screw number 5 ( Fig.4.2.1) set the gas
flow to obtain the required composition of the flue gas listed in
Table 4.3.2.1.
NOTICE:
Check the settings for the max and min. gas flow.
If the adjustment is complete, close all measuring points, then check tightness and re-seal them.
The data specified for gases at normal conditions (15
o
C, pressure 1013 mbar), having regard to boiler efficiency -97.4.
