Commissioning the system

Operating and service instructions for the control
unit and the burner
01. Check that the turbulators are fully inserted into
the hot gas flues (see page 10); open the boiler
door for this.
02. Check that the ventilation air aperture in the instal-
lation room is open.
03. Fill the heating system with water and vent the
system.
Permissible operating pressure: 4 bar (0.4 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".
04. Enter the amount of fill water and the water hard-
ness in the table in the appendix on page 25.
05. Check the system pressure.
06. Check the oil level or the gas supply pressure.
07. Open the flue gas damper (if installed).
08. Check that the cleaning aperture on the flue outlet
is closed.
09. Open the shut-off valves in the oil or gas line.
Shutting down the system
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.
Closing the Vitoair draught stabiliser (if installed)
1. Start the burner.
Opening the boiler door and cleaning cover
Note
On gas burners, disconnect the gas supply pipe.

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.
Note
When testing the flue gas for CO, internal gases
being expelled 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.
2. Shut the system down while pre-purge is active.
The control disc is closed.
