6.2 Replacement of third party appliances with the Vitodens 200-W and 300-W

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, adaptors with connection components for the heat-
ing water and DHW sides and fixing components for the replacement
of the following third party equipment with a Vitodens are available as
accessories (see pricelist).
Replacing these devices with the Vitodens will not result in a greater
installation effort than for the original equipment.
Generally, 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 gas systems for the Vitodens").
