multiple connection, the boilers may
only be operated with natural gas. A back draught safety device
must be installed in the flue gas connection and in the mixing shaft
of the burner for each boiler.
For further details, see the technical guide on flue systems for the
Vitodens.
Using third party flue systems
Any approved flue system can be used for type C

. These flue sys-
tems are not tested together with the boilers and do not have system

and observe appliance-specific information.
If aluminium flue pipes are used, a condensate trap must additionally
be installed above the boiler flue connection.
Safety equipment for the installation room
Viessmann heat generators are tested and approved in accordance
with all safety regulations and are therefore fail-safe. Unpredictable
external factors may, in the rarest of cases, lead to the potentially
harmful escape of carbon monoxide (CO). For this case, we recom-
mend using a CO limiter.
Siting the Vitodens 222-F and 242-F in recesses
When delivered, the ON/OFF switch and the electrical connections
are located on the left-hand side of the appliance. When installing in
recesses, ensure that access is guaranteed. Recommended wall
clearance min. 100 mm. Otherwise relocate the ON/OFF switch and
electrical connections accordingly. The ON/OFF switch can be relo-
cated to the right-hand side or the top. The electrical connections
can be relocated to the right-hand side.
