aint.
Start gas volume
The opening characteristics of the gas solenoid valve have been matched to
the boiler and have been preset at the factory.
Generally, you do not need to change this setting.
Please note:
If you do not wish to change the start gas volume, continue with item 19.
18. For gas trains by Dungs type
MB DLE 405 B01 (if required):
H Set the quick action (opening
characteristics) with protective
cap positioned upside down E.
For pulsating burner start:
Rotate to the right ³ reduced
quick action (less gas during the
burner start).
When the ionisation current
during the start−up phase is too
low:
Rotate to the left ³ increased
quick action (more gas during
the burner start).
H Fit the protective cap.
19. Close the gas shut−off valve,
remove the U−shaped pressure
gauge and close test nipple A
(see page 8).
20. Start up the burner.

3. Air volume fine adjustment

aint.
The air valve for regulating the air volume for Vitola boilers is factory−set.
Only make one adjustment during the initial start−up to match the system to
local conditions or to Vitorond.
The CO content in the flue gas should be approx. 9.5 %.
2
Test port (approx. 10 mm ∅) at a distance of two to three times the diameter
of the flue pipe behind the boiler adaptor.
Record the final values in the service report (you will find this report on
pages 36 and 37).
Ensure that the flue pipe is sealed at the boiler adaptor; otherwise infiltrating
air will falsify the measuring results.
Initial start−up, inspection and maintenance
Ionisation current at least 3 µA.
Checking the ionisation current see
page 15.
