Achtung : Vor der Inbetriebnahme die Bedienungsanleitung beachten.
Attention : Please read operating instructions before start - up.
Attention: Avant la mise en route, lire attentivement le mode d'emploi.
If a fan speed control is installed it is connected on the
terminal strip at the same position as the burner
through the terminals A/B (Lüfter Regl.) The existing
bridge between the two terminals is removed.
2.3 Burner Connection
The CD 20/30 units are normally delivered with ready
mounted burner. Only oil or gas supply to the burner
has to be installed. Similarly the electrical connection
is carried out through the holes at the top and bottom
of the unit.
If an alternative burner is installed it is connected to
mains by means of a Wieland plug. This plug is
already pre-mounted in the burner compartment. If
the burner has no corresponding plug/does not fit to
this plug the Wieland plug in the DV 20/30 unit should
be disconnected and electrical connection is instead
made as shown in the wiring diagram in paragraph 6
and according to the wiring diagram of the burner.
Oil and gas connection is to be made only by author-
ized specialists.
Before starting and adjustment of the burner, please
refer to the manuals from the burner supplier. If the
unit is delivered with pre-mounted burner the instruction
manual for the burner is delivered separately with the
DV unit.
2.4 Duct Connection
If ducts for air intake and exhaust are to be fitted it is
important to take care that the total pressure loss of
the entire duct system is not too large. Contact your
Dantherm dealer for information about the maximum
values. With high pressure losses in the ducts the
quantity of air will be reduced, so that the unit can will
become overheated and as a result of this switch off
(see also paragraph 5, fault finding). A too high
pressure loss will also reduce the efficiency of the
unit.
