HEYLO K 50 54kW Indirect Oil Fired Space Heater

General information

CAUTION: Read carefully before starting up!
Please observe the notes in the operating instructions carefully. In case of non-observation, the warranty claims will become void. The manufacturer shall not be liable for any damage and/or consequential damage resulting.
Equipment description
The K 30 T lit with heating oil EL, is a compact fan-assisted air heater (WLE) that can be used in many ways and is easy to transport for heating and drying. It functions equally well with and without a chimney and, with its high heat capacity, it is compact and light, but still built as a robust device. The WLE can only be used commercially.
Fan-assisted air heaters are intended for spot heating of repair areas in the open and in closed rooms, for thawing and heating of machines, devices and pipelines and for drying of rooms, hay and crops as well as auxiliary heating in emergency cases.
A tested oil burner has been installed in accordance with DIN EN 267. The current operating instructions for the WLE will definitely be supplemented by the operating instructions of the burner manufacturer for the burner.

Safety instructions

• The equipment can only be operated by sufficiently trained persons.
• Mobile fuel containers can only be installed and operated under observation of the Technical Regulations for Combustible Fluids (TRbF 20).
• Do not install and operate the equipment in oily, sulphurous or salty environments.
• The equipment should not be exposed to sprayed water (e.g. high pressure cleaners).
• Only WLE models of blower oil burners in accordance with DIN EN 230 and DIN EN 267 can be used.
• On no account can the safety facilities be blocked or bridged over.
• The equipment can only be operated unsupervised with a thermostatic regulator.
• Strictly speaking, the equipment should only be disconnected from the mains supply in a cooled off state.
• Equipment must be installed on level surfaces, ensuring that they are stable.

Equipment construction

• A ventilator and chromium-titanium combustion chamber with a heat exchanger and exhaust gas nozzle fitted in the housing.
• The oil burner is installed in the switch cabinet with its control units within the casing and above the air suction unit.
• The tuyere connection with the flame pipe is fitted on the vertically placed combustion chamber.
• Both functional units are connected to each other by means of supply lines for air, fuel as well as ignition and monitoring bodies.
• Since the flame reverses within the combustion chamber, it has to be long and slender.
• Capillary tube thermostats are installed in the device.
• The temperature regulator ensures that heating times are short when heating up by delayed switching on of the ventilator.
• When switching off, the temperature regulator allows the ventilator to run for some more time to remove the remaining heat from the device.
• The combustion chamber is thus protected from overheating due to subsequent heat at the same time.
• Efficient oil pre-heating has been installed in the devices for operation during cold external temperatures. It heats up a specific amount of heating oil until the burner can start up.
• The room thermostat connection permits room temperature dependent control of the device using a room thermostat.
  An operating hour counter has been fitted into the device. It indicates running times of the device in [h] during heating operation. The running times can be read after opening the door of the switch cabinet.

Mode of operation

• During operation, the heating oil EL is sucked in by the combustion pump through the suction pipe from the supplied tank or from a firmly installed oil supply unit. The amount of oil required for the heating performance is introduced into the burner nozzle through the pressure pipe, sprayed into the combustion chamber and ignited. A flame lights up, which, together with its combustion gases, heats the combustion chamber and the heat exchanger. Excess heating oil conveyed from the pump flows back into the container.

• After a short heating up time, the temperature regulator switches on the ventilator. A very short heating up time is achieved in this way. The ventilator blows the sucked in air through the combustion chamber and the heat exchanger. It is heated up in this way. The heated up air exits on the opposite side through the blow-out nozzle.

• The main switch is switched on to position -II- “heating” for heating up. First, the burner starts up and after heating up the combustion chamber and heat exchanger, the ventilator is also switched on and conveys hot air.

• A room thermostat that is possibly attached later on has to be set higher than the ambient temperature, otherwise the device will not start up, since there will be no electricity supply.

• The main switch is switched on to position –I- “ventilate” on the switch cabinet for ventilation. Only the ventilator is running now. The device is now functioning as
  a ventilation device.

• The main switch is set to position -0- to switch off the device.

Connections

• Power supply connection
• The device is operated with 230V alternating current, 50 Hz. The K 30 T 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 mm² or. 5 x 2.5 mm² 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.

Commissioning/start up

Heating

1. Connect the device to the oil supply lines through the flow connection and return port.
2. Plug in the mains plug in the appropriate mains supply socket.
3. If prescribed by the construction regulations, connect the chimney, else 1 m smoke tube with rain hood.
4. Turn on the main switch to position -II- “heating.” The burner will start up in the pre-ventilation mode. After approx. 45 sec. the flame will ignite.
5. If the device and/or oil are cooled off, you will have to wait for 15 – 20 minutes depending on the temperature until the oil pre-heating has pre-heated sufficiently. Only turn the main switch on to the heating mode after this and, if it is being used, set the connected room thermostat above ambient temperature.
6. Switching off: Turn off the main switch on the switch cabinet – do not pull out the mains plug -since the ventilator must keep running for a short while after switching off to cool. The temperature regulator will switch the ventilator off automatically with a delay of 2 -3 minutes. This process can repeat itself a few times. Do not, therefore, pull out the mains plug to switch the device off for any reason. If the device is turned off by pulling its plug or by pulling at the main switch, the device cannot cool off afterwards and this can lead to damages to the combustion chamber and to flame monitoring.

In certain circumstances, the safety temperature limiter can switch itself off and lock automatically. The device will then only start up again after unlocking the safety temperature switch.

Ventilation

1. Turn the main switch on to position –I- “ventilate.”
2. To switch off ventilation: Set main switch to position -0- “Off.”

Troubleshooting

**** Room thermostat (if being used) has been set too low

**** Room thermostat is defective

**** Automatic oil lighting device indicates disturbance (Lamp indicating disturbances lights up).

****The safety temperature limiter has interrupted the power supply, blow-out temperature is too high, air input and air output have been

narrowed down or device could not cool off afterwards: device was

switched off by pulling out the plug, instead of by switching off.

| Check with a voltage tester or lamp, turn on the main switch, change the fuse, check the supply line for loose contacts.

**** If device is being operated without room thermostat: check whether the cap of the room thermostat connection is on, since the heater will not start up without the cap, if necessary, place the cap on (the cap contains a power supply bridge).

**** Set room thermostat above room temperature

**** Examine room thermostat (can only be carried out by an expert). Change it or bridge it over at the fastening clamp on the device in emergency cases and switch it on manually.

**** Unscrew the switch cabinet covering. After waiting for approx. 1 minute, activate the lit up button for removing disturbances on the control unit of the burner. The indication of a disturbance on the control unit and signal should go off. The burner then attempts to start up again.

**** When starting up initially, it is possible that the button for removing disturbances has to be pressed so often, until the burner has sucked in oil that is free of air. Check that the oil in the reverse flow pipe is free of bubbles. Heating up will only be possible after this.

**** Further details on burner malfunctioning (LED code) can be found in the enclosed burner operating instructions.

**** Turn the black protective cap to the left and remove it. Press the button for removing disturbances on the STB. This can be found above the entry point for the device cable. Get rid of the cause for overheating (resistance to suctioning-in or blowing out).

**** Oil pipe is not connected or main tap is closed

**** Oil filter is dirty

**** Oil suctioning pipe is not hermetically sealed, pump sucks in air with it

**** Oil pump is not producing any pressure

| Fill up with oil

Check pipeline and/or main tap

Clean nozzle filter, pump filter, pre-filter, if necessary, change nozzle

Seal off oil suctioning pipe. The oil in the reverse flow pipe should be free of bubbles.

Set the pressure correctly. Change the coupling or pump (can only be carried out by an expert).

Activate button for removing disturbances on the control unit (see section describing burner not starting up)

Burner starts up but does not ignite, indicates malfunctioning| No ignition spark.

Carbon deposits on ignition electrodes or they are displaced.

**** Burner nozzle is blocked

| Check the tuyere connection. Pull out the mains plug or switch off the power supply and check the tuyere connection.

Unscrew the burner nozzle. Change the nozzle for a new one. Do not attempt to clean the nozzle! Keep changing the nozzle, opened, cleaned nozzles never burn flawlessly.

Flame goes out after starting up or burns intermittently| The photo conductive cell is dirty

Oil filter is dirty

Oil suctioning pipe is not hermetically sealed, pump sucks in air with it: air bubbles in the oil in the reverse flow pipe.

**** Burner nozzle blocked

**** Combustion air is not properly set

| Pull out the photo conductive cell and wipe it with a clean cloth. This cleaning should take place often in very dusty rooms.

**** Check and clean all oil filters: pre-filters, pump filters, nozzle filters.

Seal off the oil suctioning pipe, tighten all screws. Let the oil in the reverse flow pipe flow into a pot of oil. It must be free of bubbles.

Set the pump pressure correctly (can only be done by an expert).

**** As in “Burner starts up, but does not ignite”, dismantle the burner nozzle and exchange for a new one (do not clean).

**** Adjust combustion air (can only be done by an expert).

Burner does not switch off| Room thermostat has been fitted in an inappropriate place.

**** Defective room thermostat

| Fit the room thermostat at another place. It is important, for proper controlling, that the room thermostat if fitted in the room to be heated, should be fitted in such a way that no flow of cold air from windows, doors etc. comes into contact with it. If appropriate, move the room thermostat to another place.

**** Examine the room thermostat (can only be done by an expert), change it in emergency cases.
