The commissioning and matching up
of the control unit to local conditions
and the structural characteristics of
the building must be carried out by
your heating contractor.
As the user of new combustion equip-
ment, you may be obliged to notify
your local flue gas inspector of the
installation [check local regulations].
Your local flue gas inspector will also
inform you [where appropriate] about
work he may be required to perform
on your combustion equipment (e.g.
regular checks, cleaning).
Your system is preset at the factory
The control unit is already adjusted to
"Heating and hot water" in the factory,
i.e. the system provides DHW and
central heating (if a DHW cylinder is
installed).
Your heating system is therefore
ready for use.
You may change the factory settings
in accordance with personal require-
ments.
Note
All data is saved in case of power fail-
ure.
Multi-boiler system
You only require the Vitotronic 300-K
operating instructions if the boiler is
used in a multi-boiler system in con-
junction with a Vitotronic 300-K con-
trol unit. These instructions also
include the operating steps for boiler
control.

Position of the gas shut-off valve at
the Vitodens 333-F
1. Check the heating system pressure
at pressure gauge A: The system
pressure is too low if the indicator
points to the area below 1.0 bar. In
that case, top up with water or
notify your local heating contractor.
2. For open flue operation:
Check whether the ventilation aper-
tures in the installation room are
open and unobstructed.
Note
With open flue operation, the com-
bustion air is drawn from the instal-
lation room.
3. Open gas shut-off valve B.
4. Switch ON the power supply, e.g. at
a separate MCB/fuse or a main iso-
lator.
5. Switch system ON/OFF switch
"8"CON.
Standby is indicated by the green
indicator (ON indicator). The boiler
water temperature is displayed
after a short time. Your heating sys-
tem and, if installed, your remote
control unit are now ready for use.
Shutting down the heating system
If, temporarily, you have no need of your heating system, e.g. during a summer
holiday, switch the system to "Standby mode"K(see page 12).
Note
The circulation pumps are briefly started every 24 hours to prevent them from
seizing up.
