Operating and service instructions for the control
unit and the burner
0 1. Check that the turbulators are fully inserted into
the hot gas flues (see page 9); open the boiler
door for this.
0 2. Check that the ventilation air aperture in the instal-
lation room is open.
0 3. Fill the heating system with water and vent the
system.
Permissible operating pressure: 5 bar (0.5 MPa)
!
Please note
Scaling and boiler damage may result if the
system is not operated with fully softened
heating water.
Operate boilers only with softened water.
Observe the instructions in chapter "Water
quality requirements".
0 4. Enter the amount of fill water and water hardness
into the table in the appendix; see page 23.
0 5. Check the system pressure.
0 6. Check the oil level or the gas supply pressure.
0 7. Open the flue gas damper (if installed).
0 8. Check that the cleaning aperture on the flue outlet
is closed.
0 9. Open the shut-off valves in the oil or gas line.
10. Switch ON the mains isolator, the switch for the
heating circuit pump and the burner ON/OFF
switch, in that order. Observe the burner manufac-
turer’s operating instructions.
11. The dew point range must be cleared as quickly
as possible. To do so, prevent any heat supply to
the consumers when heating the system from
cold. This also applies when restarting after main-
tenance and cleaning work.
!
Please note
During boiler heat-up, unpleasant fumes
and odours can result from outgassing from
the thermal insulation, the thermal block and
the paint.
Ventilate the room during commissioning.
12. Once the flow temperature has been reached,
successively switch on the heat consumers.
Switch the burner over to automatic mode.
!
Please note
When checking CO levels in the flue gas,
internal outgassing from the thermal block
can result in higher values.
Continue to operate the boiler until a decline
can be clearly recognised.
13. Check all gaskets and plugs, and retighten if nec-
essary.
14. Check the boiler door and cleaning cover after
approx. 50 hours run. Tighten the screws.
Danger
Opening the connections on the heating water
side whilst the boiler is under pressure can
result in injuries.
First depressurise the boiler.
Only drain the boiler with a suction pump when
the air vent valve is open.
Shutting down the system
Danger
The connections on the heating water side must
only be opened after the boiler has been dep-
ressurised.
Only drain the boiler with a suction pump when
the air vent valve is open.
Closing the Vitoair draught stabiliser (if installed)
1. Start the burner. 2. When pre-purge is active, switch off the system;
the control disc is then closed.
