General Information
Safety instructions
Please follow these safety instructions closely to prevent accidents and material losses.
Work on the equipment
Installation, initial start−up,
maintenance and repairs must only
be carried out by a competent
person (heating engineers/
installation contractors) (EN50110,
part1, and VDE1000, part10, or
local regulations).
Before working on the equipment/
heating system, isolate the mains
electrical supply (e. g. by removing a
separate mains fuse or by means of
a mains electrical isolator) and
safeguard against unauthorised
reconnection.
Disconnection must be carried out
by means of an isolating device
which simultaneously isolates all
non−earthed conductors with at least
3 mm contact separation.
Repair work
It is not permitted to carry out
repairs on parts that fulfil a safety
function.
Use only original Viessmann spare
parts or equivalent which have been
approved by Viessmann.
Initial start−up
This must be carried out by the
system installer or a commissioning
engineer designated by him; all
actual values should be recorded in a
commissioning/service report.
Instructing the system user
The system installer must hand the
operating instructions to the system
user and instruct him/her in the
operation of the system.
This symbol is a reference
to other instructions which
must be observed.
Work requiring the control unit to be
opened must not subject internal
components to electrostatic
discharges.

Implementation
To obtain the optimum combustion values, it is essential to adjust the burner
with the boiler heated to operating temperature.
Check the CO content, CO2 content, flue gas temperature, room temperature
and chimney draught after 2minutes operation and at 60 ºC boiler water
temperature with fitted burner hood.
Remove the burner hood before commencing maintenance work.
Initial start−up
Service instructions
Boiler control unit
Please note:
Vitoflame 200 oil burners have
excellent combustion values which
are achieved without the use of fuel
oil additives to improve combustion.
We do not therefore recommend the
use of such combustion improvers.
1. Check whether the flame tube
attachment (for 15 to 33 kW
output) has been fitted.
2. Check the heating system
pressure and the oil level in the
tank.
3. Open the shut−off valves in the oil
supply lines on the oil tank and on
the filter.
4. Fill the oil suction line and filter
with fuel oil using the manual oil
suction pump before switching on
the burner.
5. Switch on the mains electrical
isolator (outside the boiler room).
5692452 GB
6. Switch on system On/Off
switchB on the control unit.
If fault indicator lampA on the
control unit illuminates, press reset
buttonC on the burner.
Please note:
For Vitorond 222:
For balanced flue operation the air
supply duct should be fitted before
burner setup. Observe the following
values during this step:
H Pressure loss in the air supply duct
max. 35 Pa,
H Air inlet temperature in the inlet
adaptor min. 5°C/max. 30°C.

2. Oil pressure adjustment and vacuum check
Please note:
The oil pressure is preset at the factory according to the oil throughput.
Adjust the oil pressure, if necessary.
1. Isolate the mains electricity
supply and safeguard against
reconnection.
2. Unscrew drain plug"P" A from
the oil pump.
3. Unscrew drain plug"V" B from
the oil pump.
Please note:
This allows the oil to drain from
the oil pump.
4. Insert a pressure gauge (range
0 25bar) and a vacuum gauge
(range 0 1bar); seal the gauges
only with copper or aluminium
rings or O−rings.
Please note:
Do not use tape to seal these
joints.
5. Start up the burner.
The solenoid valve opens.
6. Read off the oil and vacuum
pressures of the pump on the
relevant gauges (vacuum should
be max. 0.35bar given a head of
3 m between the oil pump and
the bottom of the tank).
Where the vacuum measures
higher than 0.35bar, check the
filter for cleanliness or the pipe
run.
7. If necessary, set the oil pressure
on oil pump pressure setting
screw C (for Danfoss pumps:
depending on the model either on
the front or the side).

1. Open the oil filter valve.
2. Switch on the mains electrical
isolator (outside the boiler room).
3. Switch on the system On/Off

Inspection Maint.
17. Checking the oil pipes and connections for leaks
The presence of air bubbles in the
prefilter is a sign of a leak in the
suction line. Check oil pipes and
connecting pipes on the oil tanks.
Leaks will cause the fuel oil to
continue to be injected (run−on) and
produce soot deposits on the sensor
plate and on the flame tube
attachment.
Maint.
18. Re−checking the burner
Please note:
The flue pipe must be sealed on
the boiler adaptor. Infiltrating air
leads to false readings.

Burner control unit
You may use the following burner
control units with this burner:
Burner control unit LOA 14.171B2V
For programming sequence, see the
wiring diagram on page 25.
Sensor current:
H min. requirement 50 µA
H max. permissible without flame
5.5µA
Undervoltage
When the mains voltage falls below
165 V~, the burner will be prevented
from starting or the oil flow will be
interrupted; simultaneously the
system will be initiating a fault
shutdown.
Fault position
A lamp in the reset button also
indicates the fault shutdown of the
burner control unit.
Please note:
If the power supply is 2×127 V and a
red flashing code: 10×flashing (see
page 19) refer to your local
Viessmann sales office.
Control sequence in case of faults
The fuel valve outputs and the
ignition system are immediately shut
down (< 1 s) if the system shuts
down because of faults.

Controlled intermittent operation
After a maximum of 24 hours
non−stop operation, the burner
control unit implements an
automatic safety shutdown with
subsequent re−start.
Resetting the boiler control unit
The system can be immediately reset
after a fault shutdown. Hold down
the reset button for approx. 1 sec.
(<3 s).
Ignition sequence
The system is re−ignited, if the flame
fails within the safety period,
however not later than at the end of
the safety period. This allows several
