, Vitodens models suit-
able for multiple connection are available for this pur-
pose.
Note
Not all appliance types are approved for "multiple con-
nection".
Vitodens models suitable for multiple connection must
be ordered for this; see pricelist.
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.
Commissioning
should be carried out only once the
following conditions have been met:
■
Unrestricted flow along 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.
Apertures for combustion air supply must be
non-sealable.
Prevent condensate drainage via a wind protec-
tor.

When carrying out any work on gas connection fit-
tings, hold with a suitable tool. Never transfer any
forces to the internal components.
