4.7 Inspection of gas nozzle before
commissioning
General rules
Care should be taken by the installer to ensure that no electrical cables
or fuel/gas pipes are trapped or damaged during installation or service/
maintenance.
Gas nozzle
Check that the ignition and ionisation electrodes are correctly set. In
the figure (see the gas nozzle chapter), the dimensions are specified for
adjustment of the ignition and ionisation electrodes.
Gas quality
Ensure that the burner head is meant for the gas quality to be used (see
capter gas nozzle).
De-aerating
De-aerating of the gas line is conducted, for example, by unscrewing
the screw on the measuring nipple for the connection pressure. Connect
a plastic hose and release the gas in a safe place. Once de-aerating is
completed, be sure to refit the screw on the measuring nipple.
Leakage control
When making a leakage control of the gas supply system the solenoid valve
should be closed. Connect a pressure gauge to the test nipple Pa, see fig.
The test pressure in the system should be 1,5x max. inlet pressure or min.
150 mbar. If any leakage, locate the source by means of soapy water or a
leak location spray. After tightening repeat the test.
Electric function test:
Ensure that phase and neutral are not reversed. The gas shut-off cock
should be closed.To prevent the gas pressure switch from locking out it
should be linked temporarily.
After the main switch has been switched on and the thermostats have been
adjusted the pre-purging period begins (30-35sec.). At the end of this period
the pre-ignition period starts (0,5-2,5 sec. dependent on the design of the
gas control). The gas valve is energized and opens and flame is established.
At the end of the safety time (2-3 sec.) the gas control locks out. The
solenoid valve and the motor will be "dead". Remove the link from the gas
pressure switch after the test is finished.
Note on 2-stage and modulating burners that during the pre-purging period
the damper opens to the set value for air on stage 2 and just before the
end of the pre-purging period it goes down to the air setting for stage 1. On
some burners under 350kW the pre-purging mainly takes place with the air
damper set for stage 1.
!If the burner is directly
connected, ensure
that all components on
the burner are without
power.

the valves are open)
-Set the switch in position MAN.
-Set the gas pressure switch min. and air pressure switch on min.
adjustment. Set the gas pressure switch max, if any, on max. adjust-
ment.
-Start the burner, observe the pressure gauge, if no flame is esta-
blished and the pressure gauge needle does not flicker, increase N.
When the flame is established adjust the gas flow by means of the
screw N. Use a flue gas instrument.
-Change over to max. load, press the switch “increase”
-Adjust the gas flow with V and check at the same time the combusti-
on values.
-Go back to min. load and check the combustion value. Adjust if
necessary.
-If necessary repeat the controls of the adjustment made on min. (N)
and max. load(V).
-Increased power on minimum and maximum have now been adjusted
by changing the orange cam and red cam. Check the gas flow on the
gas meter available on the installation.
-Note! Do not forget to set the air and gas pressure switches after the
adjustment, see special instructions.

General instructions
The gas firing system must be installed in accordance
with applicable regulations and directives. The supplier/
installer of such systems therefore has a duty to
understand all applicable regulations in order to ensure
that the installation complies with national requirements.
The installation, mounting and initial adjustments must
be carried out with the utmost care, and only gas
intended for the gas burner may be used.
User manual
The installation and maintenance instructions supplied
with the burner must be kept at an easily accessible
location in the boiler room.
Instructions
The user must be comprehensively instructed in the
operation of the gas burner and entire system. It is the
responsibility of the supplier to instruct the user.
Inspection and maintenance
Inspection as needed, preferably daily. Maintenance per
service schedule.
Start-up
Once the burner is mounted to the boiler, the electrical
connection is complete, the gas piping is seal-tested and
vented, and the electrical function test has been carried
out, the burner is ready for start-up.
However, read through the sections on setting the gas
piping, combustion air and combustion heads.
Open the ball valve and close the main switch. If the
burner starts, initial adjustments can be carried out.
Setting the combustion head
The burner is equipped with a lever that changes the
position of the brake plate in the combustion head.
This is used to set the correct pressure drop across
the combustion assembly and thereby obtain good
combustion without pulsation.
The position to be used depends on, among other
things, the firing output and overpressure in the boiler.
A general rule of thumb is that the smaller the capacity,
the smaller the column should be between the brake
plate and the combustion assembly.
Fine-tuning the system
Checking the combustion. Checking the quality of
the combustion is done using a flue gas analyser.
Set the burner to about 20% excess air according to
the adjacent table. Check the flue gas temperature.
Calculate the combustion efficiency. Also check the
current volume of gas on the gas meter to ensure that
the correct firing output is achieved.
Servicing
The person/company carrying out service and
maintenance on the burner must be authorised to do so.
If components need to be replaced, the replacements
must be of the same make and type and be approved
according to national regulations. If the burner is to be
used for a different grade of gas, readjustment must be
carried out.
