6.2 Replacing third party appliances with the Vitodens 100-W

Using an adaptor, the Vitodens hydraulic connections are compatible
with Ceramini-Z-SR, Cerastar-ZR/-ZWR, Thermoblock-VC/VC110E/
VC112E and Thermoblock-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 fixing components for replacing the
third party appliances listed below with a Vitodens.
Replacing these boilers with the Vitodens will not result in a greater
installation effort compared to replacing them with a same-brand
appliance.

Generally, where a wall mounted gas boiler is replaced by a
Vitodens 100-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 Vitodens").
Match up the flue connections on site.
Note
For modernisation projects, the State Building Regulations [Ger-
many] require the on-site installation of a gas shut-off valve with
thermally activated shut-off facility.
