GENERAL NOTES This Instruction Manual is an integral part of the device and as such must always be kept with the device. 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.
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.
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.

RECEIPT OF THE PRODUCT The warm air heaters are supplied on wooden pallets (bolted to the heater) and are protected by a carton packaging (type 1÷4) or a bubblewrap (for type 5÷7). The following items complete the supply: A plastic envelope (A) containing: • Instruction manual for the plant owner, installation personnel and for the After Sales Service. • Guarantee certificate. • Label with bar code. B A Further and only for type 5÷7: • Diffusion plenum (B) to be assembled and fastened to the heater.
HANDLING AND TRANSPORT Handling must be done by personnel with suitable equipment that has a lifting capacity adequate for the weight of the heater. If a forklift truck is used, widen the forks as far as possible. If a crane is used, hooking points are the eyes placed at the top of the heat exchanger. Type 1÷4 Type 5÷7 ATTENTION Transport and handling must be done very carefully to avoid damage to the heater and danger to persons. All Parts available from www.sparesgiant.
Safe distance Installing examples In the middle of the room – 4 sides outlet On a wall 3 sides outlet On a corner 2 sides outlet All Parts available from www.sparesgiant.com 01772 329 565 1 SIDE OUTLET NOT ALLOWED! MOUNTING THE DISTRIBUTION PLENUM The heater is supplied with a distribution plenum that is fitted with adjustable guide vanes. The vanes should be adjusted so that they can ensure a good air distribution: • • • Allow adequate air distribution. Do not create excess resistance to air flow.
On models type 1÷4 the plenum is already fitted on the heater. For transport reasons and/or for stacking, on models type 5÷7 the distribution plenum is supplied with the heater but completely dismantled. For assembly and installation, proceed as follows: • After positioning the heater at the area selected for installation, remove the bubble wrap layer. • Remove the supports (1). • Dismantle the grille panel and take out from the fan space the lateral distribution elements of the plenum.
FITTING THE DOUBLE THERMOSTAT On models type 1÷4 the double thermostat is already fitted to the heater. Models type 5÷7 are supplied with the double thermostat inserted in the seat of the burner plate and electrically connected, to guarantee integrity during transport of the heater with the plenum dismantled. For assembly after installing the plenum, proceed as follows: • 1 Take the double thermostat out of the burner plate by unscrewing and sliding it out.
SETTING THE DOUBLE THERMOSTAT The heater is supplied with the double thermostat already adjusted according to the following table: FAN Function LIMIT Function 25 – 35°C 100°C If you need to check or re-adjust the thermostat operation settings, observe the following notes. Legend: Type 1÷4 1. White push-button for Automatic-Manual ventilation (if present). 2. Electric connections for FAN function. 3. Graduated scale. 4. Holes for fastening. 5. Fan unit stop temperature indicator. 6.
DUCTING A part of the heated air can be sent via ducting to other rooms using the pre-cut hole (ø 150 for type 1÷2; ø 300 for type 3÷7) at the top of the distribution plenum. 1. Pre-cut hole. 2. Fitting with flange (not supplied). 3. Ducting (not supplied). All Parts available from FIXED PROTECTIONS www.sparesgiant.com 01772 329 565 In order to avoid accidental contact with moving parts, the heater must not be started without any one of the fixed protections, which are: • • • • Lower front panel.
ELECTRIC CABLE ENTRY The electric cables connecting the heater must be adequately protected. To access the switchboard of the control panel, proceed as follows: • Remove the lower front panel (1) of the heater by slackening the fastening screws. 1 • Remove the electric junction box cover (2) by slackening the fastening screws. All Parts available from www.sparesgiant.com 01772 329 565 • Insert the connection cables in the specific grommets.
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.

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.
IMPORTANT If the heater is replaced, but the existing burner continues to be used, make sure that: • The performance of the burner is coherent with that required by the heater. • The length and diameter of the burner sleeve correspond to the dimensions shown in the Table. DIMENSIONS P Ø max TYPE 1 80 120 2 80 120 3 80 220 4 80 170 5 150 170 6 130 220 7 130 220 If the length is greater, the length must not be more than 20% greater than the value shown. All Parts available from www.sparesgiant.
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.
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.
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.
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.
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.
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.
