Conversion Of Combi Boilers To Boilers With Cylinder - Wolf CGB-11 Installation Instructions Manual

Conversions must only be carried out by authorised
contractors.
Please carry out the following steps:
• Separate the cold water inlet and the DHW inlet from the
connecting block of the combi boiler.
• Remove the siphon.
• Separate the plug-in connection from the flow rate sensor.
• Release the pipe from the three-way valve at the plate heat
exchanger.
• Release the union from the distributor block at the plate heat
exchanger.
• Remove the disconnected assembly.
• Connect the released fittings in accordance with the Fig.
„Cylinder connections". For this, use the connection set for
Wolf cylinders from the range of Wolf accessories.
• Connect the cylinder sensor from the range of Wolf acces-
sories with the blue plug, which has become vacant.
• Install the filled siphon.
After the conversion, carry out a master reset with
power connected. Otherwise, no heat demand can
be recognised. All parameters will then be reset to
their factory settings.
If you have already made changes to the control unit parameters
to match the control unit to your system, then it is essential
to make notes of these changes beforehand and to re-adjust
your system after the master reset.
Carry out the master reset as follows:
• Switch OFF the boiler.
• Hold down the reset button and simultaneously start the
boiler.
• Only release the reset button after the illuminated ring has
flashed.
• Leave the boiler running for approx. 1 minute.
