1.6 Laying the steam hose
Installation material
11
The steam hose should be kept as short as possible. It should not be
possible to block or obstruct the steam supply lines in any way.
Furthermore, they must be protected from outside interference (e.g.
deformities, kinking etc.).
After the hose has been laid, it is advisable to re-check everything when
the hose is warm.
It is equally important to avoid condensation pockets in the hose.
Any curves should have as large a radius as possible.
If a hose is used for the steam line, it must be the original one supplied
by NORDMANN. If other hoses are utilised, NORDMANN cannot be held
responsible for any damage that may occur.
A hose clamp should be used to link the hose to the steam-distribution
pipe.
When laying the steam hose in pipes, cable ducts etc., you must verify their
resistance to high temperature (min. 100 °C). All insulation material must
also be checked for its resistance to high temperature.
If the steam line installed is of copper, small radii should be avoided
wherever possible. Every bend causes an additional resistance. A steam line
of copper must have the same diameter as the hose.
If the steam lines are long with a lot of bends and a relatively high internal
duct pressure, water may be continuously forced out of the steam cylinder,
which impairs performance.
