Before commissioning, adjust the burner air damper setting
according to the diagram Basic setting, see Technical data. After the
first start, the burner must be adjusted again for good function and
combustion.
4.2 Combustion device
The combustion device is permanently mounted and there are no
setting options other than adjustment of ignition and ionization
electrodes.
4.3 Start-up
After the burner is mounted on the boiler, the electrical connection
is complete, the gas piping is seal tested and de-aerated, and the
electrical function test has been carried out, the burner is ready for
start-up.
Read the sections on setting of the gas valve, damper motor and
combustion device before starting.
Open the ball valve and switch on the main switch, start the burner
and start adjusting the system.
4.4 Adjustment
Check the combustion using flue gas analysis instruments. Set the
burner to about 20% excess air and check the flue gas temperature.
Calculate the combustion efficiency. Also check the current amount
of gas on the gas meter so that the correct applied power is
achieved.
