Example: COB-15/20/29 oil condensing boiler with TS stratication cylinder on the right,
oorstanding (when looking at front of boiler). The pipework for the heating
ow and heating return, as well as the heating water ow and heating water
return, are connected to the stratication cylinder with corrugated stainless
steel pipes (accessories) (see chapter 9 "Installation - accessories").

Note: When selecting the installation material for the system, it is important to
observe the technical rules and any possible electrochemical processes
(mixed installation).
Cold water connection We recommend the installation of a maintenance valve into the cold water supply line. A
tested and certied pressure reducer must be installed if the cold water supply pressure
is above the maximum permissible operating pressure of 10 bar.
Provide a centralised pressure reducer if mixer taps are used.
Observe the regulations of DIN 1988 as well as those of your local water supply utility
when connecting cold water and DHW. Your warranty rights may be lost if the installation
does not comply with the illustration shown.
