This is also the case when the heater is sold to another user. The Manual must therefore be conserved and consulted carefully before any action. In the case of damage or loss, you can at any time ask the local After Sales Service for a copy of the Manual. After removing the packaging, first make sure that the contents are complete and undamaged. If the heater does not match with the Manual in any way, contact the Agency that sold the heater. Installation of the BG series WARM AIR HEATER must be carried out by qualified companies under Law 5 March 1990 n°46. On completion of the job, they provide the owner with a declaration of conformity of the correctly carried out installation, that is according to the current applicable Norms requires and according to the indications provided by the Manufacturer in this Instruction Manual. The heaters have been manufactured for room heating and they must be used for this purpose, compatibly with their performance characteristics. The Manufacturer accepts no contractual or extracontractual responsibility for damage caused to people, animals or property, due to errors in installation, adjustment and maintenance or to improper use. Excessive temperature represents a risk for health and a waste of energy. Avoid leaving rooms closed for long periods of time. Open the windows periodically to ensure an adequate air change. During the first start-up, there may be smells and smoke due to evaporation of the liquid used to protect the heat exchanger during storage; this is a normal phenomenon that will disappear after a brief operation time. The rooms must be adequately aerated. On leaving the heater unused for a long period, you should carry out at least the following operations: • Turn off the main heater switch and the main plant switch. • Close the main fuel supply valve. All Parts available from www.sparesgiant.com 01772 329 565 If the heater is not used for a long period of time, we suggest you contact the After Sales Service or other professionally qualified personnel for restarting. All heaters must be fitted exclusively with original accessories. The Manufacturer is not responsible for any damage caused by improper use of the heater and by the use of accessories that are not original. All references to Law, standards, directives and technical rules in this manual are to be considered as informative only and valid at the date of printing of the Manual. The enforcing of new dispositions or the alteration of current ones do not create any Manufacturer obligations towards third parties. Repairs and maintenance must be carried out by the After Sales Service or by qualified personnel as specified in this Manual. Do not alter or tamper with the heater: this can create dangerous situations and the Manufacturer will not be responsible for any damage. The systems that must be installed (oil pipes, electrical supplies, etc.) have to be suitably fastened and must not represent any obstacle that could cause tripping. The Manufacturer is responsible for conformity of his product to laws, directives and instructions standards current at the date of sale. Knowledge and observation of legislative instruments and of standards for the design of systems, and for installation, operation and maintenance are the exclusive responsibility of respectively the designer, the installation personnel and the user. The Manufacturer is not responsible for failure to observe the instructions in this Manual, for the consequences of any operation carried out that is not specifically foreseen, or for any translations causing erroneous interpretations. The heater is designed for operation at the thermal power and the airflow rate as specified in the Technical Data Chapter. A thermal power that is too low and/or an airflow that is too high can lead to condensation in the flue, with consequent irreparable corrosion to the heat exchanger. A thermal power that is too high and/or an airflow that is too low cause abnormal overheating of the heat exchanger with consequent actuation of the safety systems and damage to the heat exchanger. 4 FUNDAMENTAL SAFETY RULES The use of devices that employ electrical energy and/or fuel oil requires the observance of some fundamental safety rules such as: Children ad unassisted disabled persons must not use the warm air heaters. Do not operate electrical equipment such as switches, electric household equipment etc if you can smell fuel or other combustibles. In this case: • Open the doors and windows to aerate the room. • Close the fuel supply valves. • Call in quickly the After Sales Service or other professionally qualified personnel. Do not touch the heater if you are barefoot or if parts of your body are wet. Do not carry out any cleaning or maintenance operation without first deactivating the heater by setting the main system switch to "OFF" and without first closing the fuel supply. Do not alter the safety and adjustment systems without prior authorisation and indications by the heater Manufacturer. Do not pull, detach or twist the electric cables that exit the heater, even if the heater is not connected to the electrical supply. Do not open any doors that access the inside of the heater without turning the main system switch to "OFF". Do not abandon or leave available to children the heater packing materials (cartons, nails, plastic bags, etc.), as these are a potential source of danger. All Parts available from www.sparesgiant.com 01772 329 565 Do not install the heater near flammable material, or in areas where there is a corrosive atmosphere. Do not place any object on the heater or push anything through the grilles in the casing nor in the flue ducts. Do not touch the flue ducts as during normal operation these can reach high temperatures and represent a risk. Do not use any adapters, multiple sockets and cable extensions for the electrical connection of the heater. Do not install the heater in the open air nor where it could be subject to atmospheric events. Do not install the heater directly in limited spaces without adequate ventilation, as the burner air suction can create a pressure drop in the room and consequently cause serious problems. 5 DESCRIPTION OF THE HEATER The warm air heater with fuel oil burner is a device that heats ambient air using thermal energy produced by combustion. An airflow produced by a centrifugal fan is in contact with the heat exchanger wall, so heat is exchanged with no intermediate fluid. The combustion products, after losing heat, are expelled. This system allows considerable reduction of installation and operating costs, and is particularly well suited to applications where use of the heater is intermittent or occasional. During the summer, the heater can also provide ventilation only. GENERAL CONSTRUCTION FEATURES The most important parts of the heater are: • • • • • • • Combustion chamber with flame inversion in stainless steel type AISI 430 resistant to high temperatures, with low thermal loading, of appropriate shape and volume. Tube bundle with oval section fire tubes and turbulence imprints to offer maximum heat efficiency. Flue collector at the rear. Plenum for direct air diffusion with horizontal guide vanes, each separately adjustable, on four sides. Outer casing consisting of removable panels in painted steel sheet. Heat insulation, anti-radiation, for the surfaces exposed to radiation from the heat exchanger. Centrifugal fan, high performance, with double air intake and low sound emission level. The electrical system comprises: Double thermostat Fan-Limit adjusted and electrically connected to offer the following functions: • Function “FAN” (25-35°C), controls the fan start up approximately 60 seconds after ignition of the burner, and stops the fan at approximately four minutes after the burner stops. This avoids the emission of cold air on start-up, and allows the accumulated heat in the heat exchanger to be removed, guaranteeing complete recovery before stopping. • Function “LIMIT” (100°C), with Manual reset, stops burner operation if the air is overheated. • All Parts available from www.sparesgiant.com 01772 329 565 Three way switch to allow heating, ventilation only in summer, and plant stoppage.

The following points are compulsory: • • • • • Use a multi-pole automatic circuit breaker conforming to CEI-EN norms (contact aperture at least 3mm). Respect the connection L (Phase) - N (Neutral). Protect and fasten adequately the electric cables. Avoid direct contact with hot surfaces on the heater. Make an effective earthing connection, making sure the earthing cable is slightly longer than the line cables so that in the case of an accidental pull, the earthing cable will be the last to be detached. The manufacturer cannot be considered responsible for any damage caused by failure to connect the heater to earth ground) and/or by failure to observe the prescriptions in the wiring diagrams. 17 DISCHARGE OF COMBUSTION PRODUCTS The flue ducts and the connection to the chimney must be built in conformity with current applicable Norms and legislation, using rigid ducting, being resistant to high temperature and to mechanical loads, and gas tight. The correct position for the flue sampling take-off is shown in the drawing. COMBUSTION Punto diPRODUCTS prelievo SAMPLING POINT prodotti combustione Ø 2Ø H TYPE DIMENSIONS Ø H 1 120 1175 1 120 1175 1 All Parts available from www.sparesgiant.com 01772 329 565 Ø H Ø H 120 1175 1 Ø H 120 1175 The chimney must ensure the minimum depression foreseen by current Technical Standards, considering zero pressure at the connection between ducting and chimney (see table page 8). Non insulated flue ducts are a potential source of danger. Chimneys or flue ducts that are inadequately or badly dimensioned can amplify combustion noise levels and have a negative influence on combustion parameters. Joint seals must be made with materials that withstand temperatures of at least 350°C (for example sealants, mastics, silicone products). Avoid or at least limit horizontal ducts that must in all cases be sloped upwards. Use ducts with smooth internal surfaces, in materials that can withstand high temperatures and chemical corrosion by combustion products, of diameter equal to or greater than the flange on the heater. Avoid sharp bends and section reductions. Provide for a stub pipe to allow flue sampling. 18 INSTALLATION OF THE BURNER For installing the burner, making the electrical connections and carrying out the necessary adjustments, refer to the instruction manual supplied with the burner. We suggest that the fuel supply lines be built according to the figures here beside. For oil versions an adequate filter must be provided in the fuel suction line.

All Parts available from www.sparesgiant.com 01772 329 565 20 mm mm FIRST START-UP PREPARATION Before starting and testing warm air heaters, check that: • The protective film has been removed from the heater walls. • The air guide-vane orientation has been adjusted according to the position of the heater and to the needs of the room. 45° mimino Use adequate safety equipment (gloves etc.). You must open the air deflectors before installation. Open the deflectors by taking hold of the ends. • The heater is correctly positioned and the distances around the heater have been respected (see page 12). • There is fuel available and the supply valves are open. • The electrical connections to the supply and to the components (burner, thermostats, etc) have been made. All Parts available from www.sparesgiant.com 01772 329 565 The phase - neutral connection must be absolutely respected. The earthing connection is obligatory. 21 FIRST START-UP After carrying out the preparation operations for the first start-up, to start the warm air heater you must: Position the plant main switch to “ON”. • Activating the “VENTILATION” function – Set the function switch (1) to “VENTILATION” ¤. The burner remains off and only the centrifugal fan will start to circulate the room air at the inlet temperature. During the first start-up there might be the presence of odours and smokes caused by the evaporation of the fluid used to protect the heat exchanger during the storage period. It is a normal condition that will disappear after a short period of operation. It is recommended to air the served rooms. • Disabling the “VENTILATION” function – Set the function switch (1) to “0” (OFF). The centrifugal fan switches “OFF”. • Activating the “HEATING” function – Adjust the room thermostat temperature (e.g. 18°C). to the – Set the function switch (1) to “HEATING” required . All Parts available from www.sparesgiant.com 01772 329 565 The heater will go through the first stage of start-up and approximately one minute after flame ignition, the fan will start, delivering warm air to the room to be heated. The heater will remain in operation until the required temperature is reached; then, the contact on the room thermostat opens, the burner stops and after a few minutes (approximately four) the fan also stops. Successive re-starts and stops are automatic according to the temperature set, with no need for further action. 1 • Disabling the “HEATING” function – Act on the room thermostat or position the function swtich (1) on “0” (OFF). The burner stops immediately and after about 4 minutes the fan stops too. Never turn off the heater by removing the electrical supply before the fan stops; this to avoid dangerous overheating and actuation of the LIMIT thermostat. 22 0 In case of wrong switching on or working the generator will be able to make two different stop: 1. “BLOCK”, signalled by the luminous red push-button on the burner. After a “BLOCK” wait approximately 30 seconds before resetting starting conditions. To reset the starting conditions press the luminous burner push-button and wait for the flame to ignite. If restarting fails, this operation can be repeated 2-3 times at most, then check: • • • The instructions contained in the burner manual. The Chapter “Preparation for the first start-up”. The electrical connections. 2. “OVERHEAT SAFETY STOP” After an “OVERHEAT SAFETY STOP” wait approximately 10 minutes before resetting the starting conditions, or turn on the ventilation function (page 21) to reduce the waiting time. All Parts available from www.sparesgiant.com 01772 329 565 – Press the reset button (1) on the LIMIT thermostat. Or – If the fan motor cut-out switch RTV has actuated, reset by pressing the specific button inside the control panel switchboard (only on types 5÷7). If this action fails, the operations can be repeated 2-3 times at most; then check: • • • The Chapter “PREPARATION FOR THE FIRST START-UP”. The electrical connections. The Chapter “CHECKS”. 23 CONTROLS ROOM THERMOSTAT This must be installed in the room to be heated at a height above floor level of 1.5 m approximately, in a position protected from currents of hot or cold air. The thermostat controls start-up and stoppage of the heater to maintain the temperature near the value set. The thermostat is not supplied with the heater but must be requested as an accessory. OPERATION SWITCH HEATING/STOP/VENTILATION Placed on the heater control panel, this switch allows selection of the operation cycle: • • • Set to the symbol “heating", it programmes the heater so that the fan and the burner operate automatically according to the heat demand. Set to the symbol “ventilation", it controls the heater excluding operation of the burner thus, operating with the fan only, it allows summer cooling. Set to the symbol “stop”, it stops the warm air heater. The fan operates for a certain time to remove the heat accumulated in the heat exchanger. CHECKS To ensure correct operation of the heater, some fundamental parameters must be checked. Switch on the heater and: • Check that the fan unit starts approximately one minute after burner ignition. All Parts available from www.sparesgiant.com 01772 329 565 With the warm air heater in steady state (after approximately 20 minutes of continuous operation) carry out these operations: • • • • • • • • • • • • Check that there are no fuel leaks. Check the correct flow rate of the fuel measured at the counter (where possible). Check that the settings of the double thermostat are as indicated in the Chapter TECHNICAL DATA. Check that the flue temperature is as shown in the Chapter TECHNICAL DATA, with a tolerance of +/-10°C. Check that the double thermostat adjustments are as shown in the Chapter TECHNICAL DATA. Check that the graduated dial of the double thermostat indicates 50-60°C and that the LIMIT switch does not operate. Check that the temperature difference Dt between air delivered (Tm) and air returned (Tr) corresponds to that indicated in the Chapter “TECHNICAL DATA” with a tolerance of ± 5°C. Turn the double thermostat dial by hand to simulate action of the LIMIT thermostat and check that the burner switches off. Open the contact in the room thermostat and check that this acts on the burner only and that the fan unit does not stop at the same time. Check that the current taken by the main motor does not exceed nominal value on the number plate. Check that the setting of the cutout protection relay is adjusted to the nominal current value of the motor (only for types 5÷7). Check that the fan operates for approximately four minutes after the burner is switched off, before stopping. IMPORTANT 24 • An excessively low thermal power and/or an excessively high airflow rate can cause condensation of the flue, with consequent irreparable corrosion of the heat exchanger. • You MUST check for the absence of condensation within the heat exchanger during operation. This check is done by switching the burner off after approximately ½ hour of continuous operation, at the same time checking via the chimney connection that there is no trace of humidity in the flue collector and in the fire tubes. MAINTENANCE For good heater operation and conservation, we recommend you carry out periodical cleaning and maintenance operations. Any operation of this type must be carried out by specialised personnel qualified for the function. The operations must be done when the heater has cooled down, turning off both the electrical and the fuel supplies. HEAT EXCHANGER CLEANING Cleaning the heat exchanger must be done by qualified personnel, and is regulated by specific prescriptions. The operation should be done at least once a year, at the start of the winter season, proceeding as follows: Type 1÷2 Type 1÷4 – – Clean the internal surfaces of the heat exchanger (3) using brushes or other tools of suitable shapes and sizes. – Remove the deposits that accumulate in the combustion chamber (8) using a vacuum system through the burner opening (9). – Remove the deposits accumulated in the rear fluegas collector (4) using a vacuum system through the chimney connection (5) (only for models type 1÷2). Type 5÷7 2 5 1 8 All Parts available from www.sparesgiant.com 01772 329 565 – Remove the inspection panel (1), the inspection door (2), and the burner following the indications in the specific manual. – Clean the internal surfaces of the heat exchanger (3) using brushes or other tools of suitable shapes and sizes. – Remove the deposits accumulated in the combustion chamber (8) using a vacuum system through the burner opening (9). – 3 4 Remove the inspection panel (1), the inspection door (2) and the burner following the indications in the specific manual, and extract the diaphragm (only for models type 1÷2). Type 3÷4 2 1 3 9 Type 5÷7 Remove the deposits accumulated in the rear flue collector (4) using a vacuum system through the lateral inspection openings (10). 7 4 3 6 10 6 We suggest the use of protective gloves; when using ladders or other means of access, all operations must be carried out using suitable systems, in conditions of complete safety. 1 2 25 2 9 8 7 PERIODICAL FAN MAINTENANCE Type 1÷4 The motor is connected directly to the fan shaft. The fan motor does not need any maintenance, but only periodical cleaning. Type 5÷7 Cleaning the centrifugal fan requires mechanical removal of dust and of any extraneous bodies deposited on or near the rotor. Periodically check the transmission belt tension. When pressing at the centre, it should deflect by approximately 20mm. Adjust if necessary as follows: • • • • • Turn the generator off by setting the main switch on the control panel to “OFF”. Remove the protection grille. Slacken the four nuts (3) that fasten the motor support. Tighten the belt (1) by acting on the screws (2), until, when pressing at the centre, the belt deflects approximately 20mm. Tighten the four nuts (3) to fasten the motor support. Check that the motor and fan pulleys are aligned correctly. For these models too the fan motor does not require maintenance but only periodical cleaning of the protective cover of the cooling fan. THERMOSTATS Type 5÷7 All Parts available from www.sparesgiant.com 01772 329 565 The thermostats do not require maintenance save normal cleaning of the external parts of the sensitive elements. The LIMIT thermostats have fixed settings and must not be tampered with. The FAN thermostats are pre-set during manufacture and we suggest you do NOT adjust their settings. The manufacturer is not responsible for any damage caused by improper actions on the thermostats.
