Saf et y Hi nt s When using this unit make sure always to observe the applicable building- and fire-protection regulations as well as the rules of the trade cooperative association. The unit may be operated only by those persons who have been instructed accordingly. The unit is to be installed and operated in such a way as to ensure that the employees are not endangered by waste gases and radiation heat and that no fire can break out. The unit may only be installed and operated in rooms, when the air-rate fed to the unit is sufficient for combustion. Mobile fuel reservoirs may be installed only when the technical rules for combustible liquids TRBF 210 and 280 are observed. Units without waste gas pipes my be operated only in well aerated rooms. Persons are not allowed to stay permanently in the room where the unit has been installed. Relevant prohibition signs are to be fastened to the entrances. The unit is to be installed only on a non-combustible ground. The unit may not be installed and operated in inflammable and explosive surroundings. A safety zone of 1.5 m around the unit and a minimum distance of 3 m at the unit s waste gas opening are to be observed, even regarding non-combustible objects. The protective air suction lattice is always to be kept free from dirt and loose objects. Make sure not to introduce foreign matters into the unit. Make sure not to expose the unit to direct water jets. All electric cables outside the unit are to be protected from damage (e.g. caused by animals, etc.). Make sure always to pull the mains plug out of the mains socket when maintenance and repairs are carried out. An operation or use other than that indicated in these operating instructions is prohibited! In case of non-observation we will not be held responsible and our guarantee will become void. I nst allat ion Requir e- ment s The heaters may only be installed and operated in compliance with the relevant regulations, especially regulations governing the installation and operation of fireplaces and furnaces. Operators The units may be operated only by persons who have been trained in this field. Installation Install the heaters in a stable position. Install and operate the heaters so as to avoid any hazard to the personnel by fumes and radiation heat, well as to avoid any risk of fire. The heaters may only be installed and operated inside rooms if they are supplied with sufficient air for combustion and if the flue gases escape into the open through flue-pipes. The air supply is sufficient for combustion when, for example, the cubic capacity of a room is at least ten times the nominal thermal load of all heaters in the room, and a natural exchange of air is ensured by means of windows and doors. Heaters without waste gas pipe may be used in rooms, provided that these are well aerated and the percentage of substances which are injurious to health in the breathed in air do not reach inadmissible concentrations. The airing is sufficient when, for example, 1. the room capacity in m³ is at least 30 times the nominal thermal load in kw of all heaters in the room, and a natural exchange of air is ensured by means of windows and doors, or 2. there are air inlet and outlet openings, which cannot be closed, near the ceiling and the ground; the size of which in m² must be at least 0.003 times the nominal load in kw of all heating devices in the room. Do not install or operate the heaters in rooms or areas exposed to fire or explosion hazards. Room Drying The heaters may be operated in order to dry rooms without evacuating the generated gases through waste gas pipes outside, if the air supplied to those rooms is sufficient for combustion. Persons are not allowed to stay permanently in those rooms. Relevant prohibition signs are to be fixed at the entrances. Test The units are to be tested depending on the operational conditions when necessary, but a least once a year as to their operational reliability. These tests are to be carried out by an expert. 3
The burner is to be tested to determine its waste gas values. Supervision The persons charged with the operation of the units have to control the units before starting to work to make sure that there are no visible defects on the control and safety devices and that all the protection devices have been correctly set. If defects are detected, the supervisor is to be informed. If the detected defects jeopardize the unit s operational safety, the unit is to be put out of action. Open-air Installation Heaters operated in the open air must be so installed and protected against atmospheric influence that they do not cause any hazards or inacceptable annoyance. We recommend that a burner cover (REMKO accessories) is used. Installation in closed, well aerated rooms without connection to a chimney The operation of the units is admissible when the minimum air quantity needed for combustion is supplied. A safe exhaustion of the waste gases is to be ensured to exclude inadmissible pollution. Fresh air is fed from below; waste gases are exhausted towards the top. Room Heating Wast e Gas Pipes When the units are operated outside or in open rooms you do not need a waste gas pipe. However, we recommend that you use a waste gas pipe of 1 m length ( see example 2 ) with a rain hood on top of it to prevent the penetration of rainwater and dirt. If the units are used as room heaters, it will be necessary to guide the waste gases outside. The waste gas pipe components are to be laid in such a way as to ensure that a minimum draft of 0.1 mbar is guaranteed. Make absolutely sure not to generate counterpressure by inadequately laid waste gas pipes. Generally a trouble-free operation can be ensured when the waste gas pipes have been laid in an ascending manner and assembled with vertical end pipes. The waste gas pipes must reach at least beyond the eaves but preferrably above the roofridge to avoid counterpressure due to bad weather conditions (e.g. wind). All the waste gas pipe components are to be fastened reliably. Their diameter may not be smaller than that of the unit s waste gas connection piece. A minimum distance of 0.6 m must be kept from inflammable objects. Waste gas components incl. fastening materials can be supplied as accessories. For room heating, hot air generators may only be operated with a room thermostat (accessories). Make sure that sufficient fresh air is fed to ensure perfect combustion. Fresh air is to be fed preferrably through windows and doors or through sufficiently dimensioned openings in the outer wall. Attention! Avoid under- or overpressure in the room where the unit is installed, as this would result in combustion troubles. Please make absolutely sure that the suction and outgoing air opening is adapted to the fan power concerned (see rating plate). If this is not possible, the burner has to be equipped with a separate air supply device to ensure perfect combus-tion. Safety Distances Make sure to observe the following safety distances to ensure a safe operation of the unit: - towards the top, without waste gas pipe 3,0 m - towards the top, fire-retarding ceiling 1.5 m - towards the sides, non-burning objects 0.6 m - blow-off side, non-burning objects 3.0 m - suction side, for perfect air supply 1.0 m The floor and the ceiling must be from fire-retarding materials. Suction and blow-off cross sections may not be reduced. Hint! Example 1 Heater with waste gas pipe leading outside. Example 2 Heater without waste gas pipe leading outside. Example 3 Inadmissible arrangement; see hint. Make sure that the waste gas pipes are correctly installed with a condensate trap (see example 1), to avoid damage to the combustion chamber through humidity deposits (condensate) (see example 3). 4
Saf et y Faci l i t y St ar t ing Triple combination control according to DIN 3440 The device has 3 functions: 1. Fan Control (TR) The tripping point is set with the adjusting lever (fan). Rated value approx. 35 to 40 C. 2. Burner Temperature Monitor (TW) The tripping point is set with the adjusting lever (burner). Rated value approx. 110 to 115 C. 3. Safety Temperature Limiter (STB) The tripping point is fixed according to DIN 3440. After tripping, a burner restart is prevented. The reset button is operated from outside. Before a reset, check the operating conditions of the device to ensure that the STBtemperature is not exceeded again. TR Switching lever Switching Lever "AUTO" Automatic control of the air supply fan via fan control (TR) depending on the temperature of the air. "MAN" The fan works independent of the temperature of the air and can be used for continuous ventilation. Note! The device is equipped with a sensor monitoring feature and is cold-resistant down to -20 C; below -20 C the device switches off; when the temperature rises above this temperature, it switches on again. When the sensor or the capillary tube is damaged, or when an overtemperature of approximately 220 C is reached, the filling medium is emptied and the device performs a safety switch-off operation. The device is no longer operable and must be replaced. When the safety facility has to be replaced, take care not to damage or excessively bend the capillary tubes. Use only the original spare part, reference no. 1102561. Do not bend the sensor spirals near to solder points. When mounting, the sensor spirals may not be damaged or bended sharply edged. The sensors must be fixed in the mounting brackets provided by the factory. The sensors must always be free from dust and dirt. STB TW Make sure to charge a person with the operation and supervision of the unit who has been instructed sufficiently regarding the handlings concerned. Prior to starting, the unit is to be checked to make sure that there are no visible defects on the control and safety devices, that the unit has been installed correctly and that it has been properly connected to the mains. Install unit in a stable position. Make sure that air is supplied for combustion. Make sure that the air can be sucked in and be exhausted freely. Avoid overpressure and underpressure in the room where the unit has been installed. Make sure that enough fuel is supplied. (only use clean fuel oil EL and diesel, respectively) Attention! A sufficient quantity of free-flowing fuel oil must be available even with low outside temperatures. Paraffine formation can start even at a temperature of 5 C. Adequate measures are to be taken to avoid this. Hint! Any additional clauses of the relevant building regulations and technical rules for combustible liquids (TRBF 210 and 280 ) are to be observed. The waste gas values of the oil- or gas-burner are to be checked and adjusted properly by authorized experts in accordance with the local conditions. Connection to the Mains The units are operated with alternating current of 230 V. Connection to the mains is carried out by means of an installed mains cable with earthing-contact plug. Possibly required extension cables must be selected according to the existing cable length, the unit s connecting line and the intended purpose. All extension cables are to be used only after having been removed from the roller. 1 Put operating switch (1) into 0 position ( = OFF). Do not jumper or obstruct the safety features while the heater is in operation! 5

Plug the supplied bridge circuit plug (3) into the thermostat socket (4) of the switch box. Put the operating switch (1) into 1 position. Fully Automatic Heating With Room Thermostat Remove the bridge circuit plug (3). Plug thermostat plug (5) of the room thermostat (accessories) into the thermostat socket (4) of switch box. Hot Air Distribution All the units are equipped with silent and nearly maintenance-free axial fans. Hot air may be distributed only in accordance with the fan capacity of the units concerned. The possible hose/pipe lengths depend on the resistance on the air side of the used air ducts. Air is preferrably distributed through pipings or special hot air and sheet hoses, respectively. Please observe the following instructions when hot air hoses are to be fitted: Please use exclusively those hot air hoses (accessories) which have been approved by our company. The inside overlappings on the seams of the hot air hoses must run with the air current direction. Make sure that the hoses and pipes, respectively, are safely fastened to the unit s outgoing air connection piece. The pipes and hoses may not have sharp kinks and bends in order to avoid heat accumulation. In the case of increased suction temperatures or resis-tance on the unit s outgoing air side, the burner can be switched off by the temperature controller (TW) during the heating operation for a short time. When the temperature has fallen the burner is restarted automatically. 6 Put room thermostat (6) in a suitable place. The thermostat feeler may not be exposed directly to the hot air current. Preselect desired room temperature on the room thermostat (accessories). While the unit is operating, frequent startings of the burner should be avoided. When the temperature is too high on the unit s outgoing air side, the heating-operation is interrupted automatically for a longer period by the STB! Shut dow n 1 Put the operating switch (1) into 1 position. 1 Attention! Put operating switch (1) into 0 position. ( = OFF) Close fuel supply. 6 The unit runs fully automatically with the temperature which has been preselected on the room thermostat. Hint! When the oil burner has been installed by our works, the heater is equipped with a the standard oil preheating. The fan continues running to cool down the combustion chamber and then stops later. Never interrupt the connection to the mains before the end of the whole after-cooling phase (except in emergency situations). The fan can start several times before final switching off! Our guarantee does not cover damages caused to the unit by overheating! The connection to the mains of the units is to be carried out in accordance with the VDE 0100 regulations to a special supply point with protection device against faulty current.
