Establish electrical connections with the aid of the
supplied circuit diagram
Make electrical connections for the boiler with the aid
of the supplied circuit diagram. The control cabinet is
on the side opposite the combustion chamber door.
The supply cable runs through the cable gland on
the underside of the control cabinet. The supply
cable can have an external diameter of 7 - 17 mm.
Keep top side of combustion chamber free
Arrange the wiring for the draught fan and the flap
in the flue gas recirculation so the top side of the
combustion chamber remains accessible for possible
maintenance work.
Reinstall boiler casing
Reinstall the parts of the boiler casing that were
removed during the assembly.
