Rating plate
Regulation!
• The year in which the heater was first commissioned must
be shown permanently on the rating plate. For this purpose
3 year numbers are printed on the appropriate area of
the rating plate. The applicable year must be indicated by
removing the years which are not applicable.
• The HYDRONIC rating plate is attached to the burner and
must also be in easy view in the installed condition.
If this is not the case, a duplicate containing the same
information as the original rating plate can be attached.
The duplicate must be attached in a prominent position on
the HYDRONIC or on a cover in front of the HYDRONIC.
The duplicate is affixed to the hood in a manner which enables
it to be taken off.
Please note!
• The case must be sufficiently ventilated from outside that
the permitted ambient temperature is not exceeded.
• Air vents must be arranged on the case in such a way that
they cannot become clogged up with dirt or snow.
• Any water which penetrates the case must be able to flow
out.
Installation of the HYDRONIC in a case
If installation in the engine compartment or stowage
compartment of the vehicle is not possible, than the
HYDRONIC can also be installed in a case.
The case containing the installed HYDRONIC is then affixed
to the vehicle at a suitable location, e.g. to the longitudinal
chassis frame.
It is recommended that a hood with a hose connection is
mounted for the combustion air intake. The combustion air is
then drawn in outside of the case via a flexible hose.
In this way it is possible for the combustion air to be drawn
from an area where the temperature is within the permitted
range and protection is provided against dirt accumulation.
Place a protective grille on the flexible hose.
