5. Connections

Power supply connection
The device is operated with 230V alternating current, 50 Hz. The K30 / K30T is operated
through a 2.5 m long cable with a three-pin plug. Power supply connection should only take
place on networks that are secured with a fuse of a minimum of 10 A. Longer supply lines
should have a cross section of at least 3 x 2.5 mm ² or. 5 x 2.5 mm ² to avoid a drop in voltage in
the device that is too high. In the case of low voltage of up to 195 V the device still functions
flawlessly, so check the device's voltage if there are disruptions.
Operation with room thermostat
If the device is to keep the temperature in closed rooms constant, a 230 V room thermostat is
connected to it. The cap on the connector must be removed for this purpose. The thermostat
plug can now be plugged into the connector socket.
Oil pre-heating
Heating oil secretes paraffin at low temperatures. It blocks the oil filter and stops it from
pumping. The devices do not start up and are therefore equipped with electrical heating
elements. Oil pre-heating enables the oil to flow. It is controlled by a thermostat, independent of
the device switch. However, the mains supply plug must be connected to a functioning and
secured power supply source.
Chimney connection
Although the devices do burn without a smoke tube in the open and in open rooms, we
recommend 1 m of tubing with a 150 mm diameter and a rain hood to stop penetration of rain
and dirt as far as possible and to produce less of a draught.
In case of temporary operation in closed rooms, e.g. winter construction projects, the
combustion gases must be discharged into the open. The exhaust gas pipe must be laid out in
such a way, that at least 10 Pa draught is ensured in it and no counter pressure whatsoever
is possible in the pipe. For this reason, please take care that the exhaust gas pipe is inclining
and that it runs vertically upwards towards the end. It should at least be led above eaves height,
even better above ridge height, to prevent counter pressure from the wind and thus emission of
swirling soot from the burner. The exhaust gas pipes must be located at a minimum distance of
0.5 m from the combustible parts and be firmly attached. Their diameter should not be smaller
than that of the exhaust gas nozzle of the fan-assisted air heater.
According to construction regulations, connection to a chimney with a 200 mm diameter that
has to be led at least 0.40 m above the ridge, is prescribed for permanent operation in closed
rooms.
