The surface heating can be installed with any
standard pipe material. The Oventrop pro-
gramme includes a variety of compression fit-
tings. The corresponding installation instruc-
tions are to be observed.
Insert the copper pipe a maximum of
5 mm deeper than the fitting.
An open ring spanner, for instance Oventrop
item no. 1401092, is recommended to tighten
the fittings.

5.4 Leakage test

After installation, the system can be filled and
bled, for instance at the valve.
Then carry out leakage test according to
DIN EN 1264. The tightness and the test
pressure are to be documented in a test
report.
Now remount the protection cap of the valve.

5.5 Heating up

After all plastering finished, a heating screed
complying with standards has to be laid.
The concrete and anhydrite screed have
to be heated up according to DIN 1264-4.
