Using an adaptor, the Vitodens hydraulic connections are compatible
with Ceramini-Z-SR, Cerastar-ZR/-ZWR and Thermoblock-VC110E-/
VC112E/-VC/-VCW boilers.
For modernisation projects, adaptors are available as accessories
(see pricelist). These comprise connection components for the heat-
ing water and DHW sides and fixings for replacing the third party
appliances listed below with a Vitodens.

Replacing these boilers with the Vitodens is no more work than
replacing them with a same-brand appliance.
Where a wall mounted gas boiler is replaced by a Vitodens 200-W or
300-W gas condensing boiler, the flue must also be replaced with a
system that is suitable for "condensing operation" (see pricelist for
"flue systems for the Vitodens").
Adapt the flue connections on site.
