Connecting several Vitodens to a shared flue sys-
tem
If multiple Vitodens are to be connected to a common
flue system, suitable Vitodens appliances are availa-
ble.
Note
Not all appliance types are approved for "multiple con-
nection".
Please order suitable Vitodens appliances; see pricel-
ist.
Note
In appliances for "multiple connection", a special back
draught safety device is installed in the mixing shaft of
the burner, downstream of the fan.
A further back draught safety device (order separately)
must be installed in the flue system above the boiler
flue connection.
Only carry out commissioning when the following
conditions have been met:
■ Unrestricted flow in the flue gas routes.
■ Positive pressure flue system is gas-tight.
■ Inspection port covers checked for secure and tight
seating.
Apertures for supplying sufficient combustion air are
■
open and cannot be closed.
■ All current regulations on installing and commission-
ing flue systems have been observed.
Danger
Leaking or blocked flue systems, or an inade-
quate supply of combustion air can cause life
threatening poisoning from carbon monoxide in
the flue gas.
Ensure the flue system is in good working order.
Vents for supplying combustion air must be non-
sealable.
Prevent condensate drainage via a wind protec-
tor.
