Installation
Heating circuit connection set
Fig.: Heating circuit connection set (accessory)
We recommend you connect the heating system with
the aid of a heating circuit connection set.
Connection set comprising:
Boiler connection with flat packing; connection to the
heating flow and return with ball valves 1" (fem. th -
read).
Notes:
Provide a fill and drain cock at the lowest system
point.
The TGB-35 and TGB-50 are not factory-fitted with an
expansion vessel. Therefore, install an expansion vessel
on site (available as WOLF accessory).
Never install between the expansion vessel
and the condensing boiler, otherwise the
boiler will suffer permanent damage as
soon as the pressure builds during heat-
up. System components may burst, which
would result in a risk of scalding.
An exception would be cap valves upstream of the
expansion vessel.
There is no factory-fitted safety valve. Route the blow-
off line into a drain funnel. Minimum system pressure
0.75 bar.
CGB-35 and CGB-50 are approved exclusively for
sealed systems up to 3 bar. The maximum flow tempe -
rature is factory-set to 75 °C and may be adjusted to 85
°C, if required. The expansion vessel must be adequately
sized in accordance with DIN 4708.
