Only carry out
commissioning
when the following
conditions have been met:
■
Unrestricted flow in the flue gas routes.
■
Positive pressure flue system is gas-tight.
■
Inspection port covers checked for secure and tight
seating.
■
Apertures for supplying sufficient combustion air are
open and cannot be closed.
■
All current regulations on installing and commission-
ing flue systems have been observed.
Danger
Leaking or blocked flue systems, or an inade-
quate supply of combustion air can cause life
threatening poisoning from carbon monoxide in
the flue gas.
Ensure the flue system is in good working order.
Vents for supplying combustion air must be non-
closable.

Drain to the public sewage system
Connect the condensate pipe to the public sewage
system by the shortest route, with a constant fall and a
pipe vent. Install a neutralising system if required.
Note
DWA-A 251 permits boiler use without a neutralising
system when operating with low sulphur fuel oil
DIN 51605-EL-1 (sulphur content
≤
50 mg/kg).
We recommend using the active charcoal filter (acces-
sories) if no neutralising system is connected.
Installing the oil supply as a single line system
Note
Observe the "Technical Regulations for Oil Systems
(TRÖl)" when installing and testing the oil supply.

Install a supply line with
7
4 mm (internal). Replace
the supply line if an existing system is fitted with a line
with larger internal diameter.
Install a single line fuel oil filter R
⅜
(filter grade max.
5
µ
m) and a fuel oil air vent valve in the oil supply.
We recommend:
■
Automatic fuel oil air vent valve with filter: FloCo-
TOP-2KM-Optimum (filter grade 5
µ
m).
■
For replacement during maintenance work:
Microtec MC-18 oil filter element (filter grade 5
µ
m).
■
For part no., see Vitoset pricelist.
For tanks sited below the oil burner pump:
If the suction head or the max. pipe length is greater
than specified in the following table, install an oil feed
pump with intermediate tank in the immediate proxim-
ity of the boiler.
