Ask your heating contractor about the
following:
■ Level of the required system pressure
■ Position of the following components:
– Pressure gauge
– Shut-off valve
– Gas shut-off valve
– Vents
1. Check the heating system pressure
at the pressure gauge. The heating
system pressure is too low if the indi-
cator points to the area below
1.0 bar. Top up with water or notify
your local heating contractor.
2. For open flue operation:
Check that the ventilation apertures
of the installation room are open and
unrestricted.
Note
With open flue operation, the com-
bustion air is drawn from the installa-
tion room.
3. For Vitodens and Vitopend:
Open the gas shut-off valve.
For Vitoladens:
Open the shut-off valves in the oil
lines (at the tank and filter).
4. Switch ON the power supply, e.g. at
a separate MCB/fuse or a mains iso-
lator.
