DBW 2010 / 2012 / 2020 / 2022 / 300 / 350 6. Function Test
601
6 The Function Test
6.1 General
The tests and settings have been defined in this section
that will be carried out in assembled status and in
dismantled status from the vehicle in order to prove that
the heating device is functional.
DANGER
The heating device should not be operated in closed
places such as garage or workshop without the exhaust
suction mechanism.
Do not operate the heating device while the burner is
working because of fire danger.
6.2 The Settings
6.2.1 Setting the CO
2
proportion
The amount of the combustion air that will be set in the
factory can be changed, which will be achieved by turning
the setting ring.
The CO
2
value must be measured in the exhaust gas in
the following cases and the combustion air amount must
be adjusted if necessary:
- After the burner has been repaired
- In case of disorderly combustion
- In the scope of the function test
- After the nozzle has been replaced
The adjustment
- Measure the access voltage at the heating device
- Operate the heating device approximately for 5
minutes
- Measure the CO
2
value and emission and
compare them to the relevant graphics
