Connecting the heating flow/return
The installation set contains 2 tees (G¾") and 2 drain & fill
valves (R½").
Screw the drain & fill valves into the tees and fit them with a flat
gasket to the heating flow and return of the heating module.
Heating circuit safety valve
The appliance is fitted with an integral 3 bar safety valve below
the heating circuit pump and the installation set contains a
corresponding connection hose for push-fit connection.
Cold water and DHW connection
A maintenance valve must be installed in the cold water
supply line.
If the cold water supply pressure is above the maximum
permissible operating pressure of 10 bar, install a tested and
certified pressure reducer in accordance with Wolf accessories.
If mixer taps are used, provide a centralised pressure reducer.
Observe the regulations of DIN 1988 [Germany] as well as
those of your local water supply utility when connecting cold
water and DHW.
Your warranty is void if the installation does not comply with
the illustration shown.
Note: When selecting the installation material for the
