Electrical installation by qualified personnel only!

Local regulations and codes of practice, as
well as regulations from the energy supplier
must be observed.

Mains and emergency switch

The external mains switch for the heating system must
have at least 3 mm contact distance.

☞

Connection to plug assignment, Ch. 4.6.1.

Electrical connection

The gas condensing boiler WTC is wired ready for
connection. The cover of the electrical installation duct
must be removed for the electrical installation.
Insert the cable from the rear through the recess into the
unit.
The electrical connection must be carried out by a
qualified electrician. Changes to the internal boiler wiring
are not permitted.

Shell clamps should be used if flexible
cables are connected.
Approved sleeve cable should be used for
all other connection lines.
