BURNERS

• This equipment must be used only for its expressly stated use: applied to boilers, hot air boilers, ovens or other similar equipment and not exposed to atmospheric agents. Any other use must be regarded as improper use and hence dangerous.

• The burner must be installed in a suitable room that has ventilation in

correct combustion

• Do not obstruct or reduce the size of the burner’ air intake grills or the

or dangerous mixtures of toxic and explosive gases may form.

• Before connecting the burner check that the details on the plate correspond to those of the utility supplies (electricity, gas, light oil or other

fuel).

• Do not touch hot parts of the burner. These, normally in the areas near to the  ame and any fuel pre-heating system, become hot when the equipment is working and stay hot for some time after the burner has stopped.

ELECTRICAL SUPPLY

• The equipment is electrically safe only when it is correctly connected to an ef cient ground connection carried out in accordance with current safety regulations. It is necessary to check this essential safety requirement. If in doubt, call for a careful electrical check by a quali ed technicians, since the manufacturer will not be liable for any damage caused by a poor ground connection.

• Have quali ed technicians check that the wiring is suitable for the maximum power absorption of the equipment, as indicated in the technical plate, making sure in particular that the diameter of cables is suf cient for the equipment’s power absorption.

• Adapters, multiple plugs and extension cables may not be used for the equipment’s power supply.

• According to current safety regulations, an omnipolar switch with a contact opening gap of at least 3 mm is required for the mains supply connection.

• Extract the power cable external insulation as strictly necessary for the connection, in order to avoid that the cable comes into contact with metal parts.

• An ominpolar switch in accordance with current safety regulations is required for the mains supply connection.

• The electrical supply to the burner must have neutral to ground connection. If the ionisation current has control with neutral not to ground it is essential to make a connection between terminal 2 (neutral) and the

ground for the RC circuit.

• The use of any components that use electricity means that certain fundamental rules have to followed, including the following:

- do not touch the equipment with parts of the body that are wet or damp or with damp feet

- do not pull on electrical cables

- do not leave the equipment exposed to atmospheric agents (such as rain or sun etc.) unless there is express provision for this.

- do not allow the equipment to be used by children or inexpert persons.

• The power supply cable for the equipment not must be replaced by the user. If the cable gets damaged, switch off the equipment, and call only on quali ed technicians for its replacement.

• If you decide not to use the equipment for a while it is advisable to switch off the electrical power supply to all components in the system that use electricity (pumps, burner, etc.).

GAS, LIGHT OIL, OR OTHER FUEL SUPPLIES

General warning notes

• Installation of the burner must be carried out by quali ed technicians

and in compliance with current law and regulations, since incorrect installation may cause damage to person, animals or things, for which damage the manufacturer shall not can be held responsible.

• Before installation it is advisable to carry out careful internal cleaning

of all tubing for the fuel feed system to remove any residues that could jeopardise the proper working of the burner.

• For  rst start up of the equipment have quali ed technicians carry out

the following checks:

• If you decide not to use the burner for a while, close the tap or taps that

supply the fuel.

Special warning notes when using gas

• Have quali ed technicians check the following: a) that the feed line and the train comply with current law and regulations. b) that all the gas connections are properly sealed.

• Do not use the gas pipes to ground electrical equipment.

• Do not leave the equipment on when it is not in use and always close the gas tap.

• If the user of is away for some time, close the main gas feed tap to the

burner.

• If you smell gas:

a) do not use any electrical switches, the telephone or any other object

that could produce a spark;

b) immediately open doors and windows to create a current of air that

will purify the room;

c) close the gas taps; d) ask for the help of quali ed technicians.

• Do not block ventilation openings in the room where there is gas equipment or dangerous situations may arise with the build up of toxic and explosive mixtures.

FLUES FOR HIGH EFFICIENCY BOILERS AND SIMILAR

It should be pointed out that high ef ciency boilers and similar discharge combustion products (fumes) at relatively low temperatures into the  ue. In the above situation, traditional  ues (in terms of their diameter and heat insulation) may be suitable because the signi cant cooling of the combustion products in these permits temperatures to fall even below the condensation point. In a  ue that works with condensation there is soot at the point the exhaust reaches the atmosphere when burning light oil or heavy oil or the presence of condensate water along the  ue itself when gas is being burnt (methane, LPG, etc.). Flues connected to high ef ciency boilers and similar must therefore be of a size (section and heat insulation) for the speci c use to avoid such problems as those described above.

BURNER CONNECTION TO THE BOILER

ASSEMBLING THE HEAD UNIT

Make sure that the combustion head penetrates the furnace by the amount specified by the boiler manufacturer . Prior to installing the burner in the boiler, make sure the nozzle is suitable for the power required, if this is not the case, replace it following the instructions provided in the diagram стр.15 For the handling of the burner, it is recommended to use a suitable

ENGLISH

hoisting equipment to be anchored to the eyebolts shown in figure

0002937170.

Anchor the burner to the boiler door as follows:

• Place the two insulating seals (B) on the burner connection flange (A)

• Anchor the flange (A) to the boiler (C) with the stud bolts,

washers and nuts provided (D).

Seal the space between the burner sleeve and the hole on

the refractory material inside the boiler door completely with suitable material.

ELECTRICAL CONNECTIONS

It is recommended that all connections are performed with electrical exible wires. Power lines must be outdistanced from the hot parts. Check that the power line to which the device is connected is powered with voltage values and frequency suitable for the burner. Make sure that the main line, the relevant switch with fuses (essential) and the possible limiter are suitable to stand the maximum current

absorbed by the burner.

For more details, see the relevant wiring diagrams for each single

burner.

FUEL (DIESEL) SUPPLY SYSTEM

The burner pump must receive the fuel from a suitable supply circuit featuring an auxiliary pump which may feature a pressure regulator adjustable from 0.5 to 3 bar. In this case, the fuel supply pressure to the burner pump (0.5 ÷ 3 bar) must not change both with burner off and with working burner at the maximum fuel output required by the boiler. In normal cases, this circuit can be realized without pressure regulator, abiding to the following diagram. The supply circuit must

ENGLISH

be realized according to diagram 8666/3.

The pipe dimensioning must be carried out according to the pipe length and the ow rate of the installed pump. Our instructions ensure a good operation of the product. The anti-pollution prescriptions, as well as the provisions set forth by the local authorities, refer to the specic publications.

DUAL FUEL BURNER IGNITION INFORMATION:

We recommend performing the first ignition with liquid fuel because, in this case, the output is conditioned by the nozzle that is used, whereas the output of natural gas can be varied as required by regulating the flow rate regulator.

HYDRAULIC DRAWING OF SUPPLY FOR ONE OR MORE DIESEL TWO-STAGE OR MODULATING BURNERS WITH MAXIMUM NOMINAL VISCOSITY (5°E AT 50°C)

ASSEMBLING THE GAS TRAIN

The EN 676 approved gas train is sold separately from the burner . The gas train can be assembled in different ways: A and B. Choose the most rational position for the set-up of the boiler room and the position in which the gas pipe arrives.

HINGE UNIT ASSEMBL Y

The burner hinge can be opened both ways, it is therefore possible to reverse the opening side of the ventilating body. As a standard, the burner is supplied with the hinge installed on the right side . To enable the maximum opening and so facilitate maintenance operations, it is recommended to install the hinge on the side of the burner opposite to the position where the gas train is installed. In case it is necessary to install the hinge on the left side, proceed as follows:

• After installing the burner on the boiler, loosen the N fastening

screws and open the ventilating body to the amount needed for the removal of the E centring pin (0002937220).

• Close the burner again by re-tightening the N screws and remove the two F hinges and the G pin.

• Then, remove the 3 N screws and the relevant washers on the left side of the flange and refit them on the right side T in correspondence with the holes left free after removal of the

hinges.

• Fit the hinge unit on the burner left side (0002937230).

Initially place the F hinges without tightening the 4 H screws.

First make sure that the S abutting surfaces of the two hinges are perfectly in contact with the corresponding volute sides. Prior to this, tighten the 2 M nuts and the relevant washers. Do not tighten the nuts too deeply, as this may make hinge

rotation difficult. Carry out the final tightening of the H screws

to complete the operation.

ENGLISH

• Open the ventilating body again to make sure that the hinge unit rotates correctly and re-fit the centring pin on the side of the fan flange opposite to the hinge side in order to facilitate

closing again of the burner.

Each time the burner has to be opened, first disconnect the

connectors to the gas butterfly servomotor, to the diesel pressure regulator, to the gas solenoid valves and to the

diesel circuit.

DIAGRAM ILLUSTRATING GAS TRAIN PRINCIPLE

Install a manual on/off valve upstream of the gas valve and

a vibration-proof joint according to the layout shown in the diagram illustrating the principle.

To ensure optimal functioning of the pressure control, it should be applied to the horizontal pipe after the filter. The gas pressure regulator must be adjusted while operating at the maximum flow rate actually used by the burner. The outgoing pressure must be adjusted to a value slightly below the maximum possible

ENGLISH

value (the value obtained by screwing in the adjustment screw almost completely); in this case, the outgoing regulator pressure increases as the adjustment screw is tightened, and decreases as it is slackened.

DIESEL IGNITION AND REGULATION

• Turn the switch on the control panel to the “O” position (open).

• Turn the switch “fuel change-over” to the “OIL” position.

• Close the auxiliary air to the head unscrewing the pawl (A)

and pulling the rod (B) down to its end of stroke. Retighten the pawl (A).

• Close the gate and open the shut-off elements.

• Check that there is water in the boiler and that the gates on the

system are open.

• Make sure that the products of combustion can be released freely (boiler and chimney dampers open).

• Check that the voltage of the electric line the equipment must be connected to, complies with the manufacturer prescriptions, and that the motor electric connections are properly set for the available voltage. Also check that all electric connections made on-site are performed correctly as shown in our wiring diagram.

• Start the fuel supply auxiliary circuit and check for its correct operation, then set pressure to nearly 0,5÷3 bar if such circuit features a pressure regulator.

• Remove the vacuum gauge connection plug from the pump and open the gate on the fuel pipe. Wait for the fuel to flow out of the hole without air bubbles and close the gate. In case no supply circuit under pressure is available, fill the pump by pouring fuel into the supply hose.

• Fit a pressure gauge (full scale approx. 4 bar) to the pump vacuum gauge connection point to check the pressure value at which the fuel reaches burner pump. Fuel pressure must remain within 0,5÷3 bar also when the burner is off.

• Open the gates placed on the diesel pipes.

• Power the electric line to which the burner is connected. Manually

press the specific remote control switches to check that the fan and pump motors turn in the correct direction. If necessary, change the position of the two cables of the main line to reverse

the rotation direction.

• Start the burner pump by manually pressing the relevant remote

control switch until the pump pressure gauge detects a slight pressure. A slight pressure in the circuit indicates that it has been filled up.

• Connect (pos. I) the switch (1) on the control panel to power the equipment and close the thermostat line turning the selector (2) in the "closed" position. If thermostats or pressure switches (safety and boiler) are closed as well, the operating cycle will start. The equipment turns on. For the regulation of the burner, see la “RAPID GUIDE TO PROGRAMMING” and the specific instruction manual for the “BT 340” electronic cam .

• Check that the flame detector is triggered.

• FLAME SENSOR

If the flame is detected by the UV photocell remember what specified below. A slight amount of grease will strongly compromise the passage of the light radiations, preventing the internal sensitive element from receiving the quantity of radiations required for proper operation. If the bulb is fouled, it must be properly cleaned. Even the simple contact with your fingers can leave a slight amount of grease that is enough to compromise the

operation of the photocell. The photocell does not "detect" daylight or the light from a common lamp. Its sensitivity can be tested using a flame (lighter, candle). To ensure a proper operation, the cell voltage value must be sufficiently stable and not go below the minimum value required for the specific equipment. The check is performed between the terminals of the electric panel as shown in the wiring diagram.

• When the burner is working at its "minimum" output, adjust the air and diesel in the proper quantities to ensure a good combustion.

ENGLISH

• After adjusting the air for the operation at the "minimum" output, increase the power and proceed to define the operating curve as described in the equipment manual. It is recommended to check combustion using the specific instrument at all intermediate points on the modulation curve. The maximum output is obtained with a return pressure of approx. 17 - 18 bar at a pump pressure of 25 bar (0002922840 стр. 15). It is recommended not to exceed the value of 13 %

of CO

GAS (METAL GAS) IGNITION AND REGULATION

• Turn the switch on the control panel to the “O” position (open).

• Turn the switch “fuel change-over” to the “GAS” position.

• Open the auxiliary air to the head unscrewing the pawl (A)

and pulling the rod (B) down to its end of stroke. Retighten the pawl (A)

ENGLISH

• Close the gate and open the shut-off elements.

• Check that there is water in the boiler and that the gates on the system are open.

• Make absolutely sure that the products of combustion can be released freely (boiler and chimney gates open).

• Check that the voltage of the electrical line to which the equipment has to be connected is appropriate for the burner and that the electrical wiring (engine or main line) are appropriate for the available voltage. Check that all electrical connections made on-site are performed correctly as shown in our wiring diagram.

• It is essential to bleed air out of the pipes, if this has not already been done when connecting the burner to the gas pipe, taking all necessary precautions and leaving all doors and windows open. Open the union on the pipe near the burner and then open the gas on/off cocks a little way. Wait until you smell gas, close the cock. Wait long enough for the gas in the room to disperse, depending on local conditions, then connect the burner to the gas pipe again.

• Apply a pressure gauge of appropriate scale (if the amount of pressure to be used permits, it is preferable to use a water column instrument; do not use instruments with indicator hands for low pressures) to the pressure intake on the gas pressure switch.

• With burner switch to “O” and main switch turned on, manually close the remote control and check that the motor revolves in the correct direction. If necessary, change the position of the two cables in the line that feeds the motor in order to reverse the direction of revolution.

• Connect (pos. I) the switch (1) on the control panel to power the equipment and close the thermostat line turning the selector (2) in the "closed" position. If thermostats or pressure switches (safety and boiler) are closed as well, the operating cycle will start. The equipment turns on. For the regulation of the burner, see “RAPID GUIDE TO PROGRAMMING” and the specific instruction manual for the “BT 340” electronic cam .

• Check that the flame detector is triggered (UV cell) with the burner on, remove it from its housing in the burner and check that it shuts down.

• Check the efficiency of the thermostats or boiler pressure switches (they should shut down the burner when triggered).

properly cleaned. Even the simple contact with your fingers can leave a slight amount of grease that is enough to compromise the operation of the photocell. The photocell does not "detect" daylight or the light from a common lamp. Its sensitivity can be tested using a flame (lighter, candle). To ensure a proper operation, the cell voltage value must be sufficiently stable and not go below the minimum value required for the specific equipment. The check is performed between the terminals of the electric panel as shown in the wiring diagram.

• When the burner is working at its "minimum" output, adjust the air and gas in the proper quantities to ensure a good combustion.

• Once the regulation of air and gas is complete, check the amount of gas actually delivered by reading the meter. Do not permit the burner to operate if the combusted thermal flow rate exceeds the maximum one permitted for the boiler, to prevent it from being damaged. Upon defining the modulation curve, it is possible to have an approximate estimate of the thermal flow rate delivered at the intermediate points be measuring the gas pressure in the combustion head. Connect a pressure gauge with scale appropriate to the port (G) (see picture) and measure the gas pressure. From diagram (0002922850 стр. 17) obtain the thermal flow rate delivered, depending on the value of the pressure measured without the back pressure in the furnace.

This method permits only an approximate estimate of

the combusted thermal flow rate delivered, for a precise measuring, refer to gas meter.

Example:

• Burner TBML 800

• Pressure measured on port G: Ptc=48 mbar

• Back pressure measured in the furnace: Pcc=10 mbar

• Head pressure value without the back pressure in the furnace:

P=48-10=38 mbar

• From the diagram, in correspondence of pressure P=38 mbar, a

combusted thermal flow rate of about 7300 kW can be inferred.

AIR PRESSURE SWITCH FUNCTIONAL DESCRIPTION

The air pressure switch is used to lock the equipment if air pressure is not at the expected value. The pressure switch must be set to trigger when the air pressure in the burner does not reach the sufficient value. To ensure the air pressure switch correct operation, with burner at the minimum output, increase the adjustment value until reaching the triggering value which must be followed by the immediate burner

ENGLISH

shut-down. Press the release button to resume the burner operation, and set the pressure switch to a sufficient value to detect the air pressure during the first phase of pre-ventilation.

GAS PRESSURE SWITCH FUNCTIONAL DESCRIPTION

The gas pressure switches (minimum and maximum) prevent the burner from operating when gas pressure is not between the expected range. The specific function of the pressure switches clearly reveals that the pressure switch for controlling minimum pressure uses the NO (normally open) contact which closes when the pressure switch detects a pressure value above the value it is set to, while the pressure switch for controlling maximum pressure uses the NC (normally closed) contact that is closed when the pressure switch detects a pressure lower than the value it is set to. The minimum and maximum gas pressure switches must be set when testing the burner, on the basis of the pressure measured in each case. The pressure switches are connected in a way in which the triggering (i.e. circuit opening) of the pressure switch controlling the maximum pressure produces the immediate locking of the burner; whereas, when the pressure switch controlling the minimum pressure is triggered, the burner stops and remains in the stand-by status until the pressure within the values needed for the operation is restored. After that, the burner re-starts in an autonomous way following the

ignition sequence.

Regulation prior to burner ignition: regulate the pressure switch for minimum pressure at the minimum value of the scale, regulate the pressure switch for the maximum value at the maximum value of the scale. Regulation after the burner regulation : With the burner at the maximum delivery, regulate the pressure switch for minimum pressure by increasing the regulation value until the burner shuts down, read the value on the regulation ferrule and set it to a value diminished by 5 mbar. With the burner at the minimum delivery, regulate the pressure switch for maximum pressure, diminishing the regulation value until the NC (normally closed) contact opens. Read the value on the regulation ferrule and set it to a value increased by 5 mbar.

in case only one pressure switch is installed on the gas trainit

must be a pressure switch for minimum pressure.

MAINTENANCE

The burner does not require any particular maintenance, it is recommended at least to carry out the following operations at the end of the heating season:

• Clean air dampers, the air pressure switch with pressure port and the relevant pipe.

• Clean the photocell.

• If necessary, have the burner and the chimney cleaned by

ENGLISH

specialized personnel (stove repairer); a clean burner is more

efficient, lasts longer and is quieter.

• Periodically check that the gas filter is clean for gas burners.

• In order to clean the combustion head, its components

must be disassembled. Be careful during the reassembly operations to exactly centre the gas diffuser with regard to the electrodes, making sure that they are not earthed, which would result in the locking of the burner. After regulating the two electrodes as described at diagram

0002937182. Make sure that the ignition spark occurs only between the two electrode ends.

• Analyse combustion gases and check emissions values.

• Check that all components of the combustion head are in good

condition, have not been deformed by high temperatures and are free from impurities or deposits deriving from the installation environment or from poor combustion. If it is necessary to clean the combustion head, take out its components according to the procedure described below:

- remove the UV photocell

- Disconnect the connectors of gas and diesel solenoid valves,

the gas servomotor and of the pressure regulator.

- unscrew the anchoring screws (N), and open the ventilating

body;

- pull out the ignition cables (I) from their ignition electrode

terminals (L);

- Unscrew the caps (O), on one of which the pressure gauge

indicating the pressure in the return circuit is installed, to enable the draining of the residual diesel still present in the atomization unit. Disconnect the unit connection pipes, unscrewing the nuts (M) of the "T" -shaped unions.

- Loosen the nut (A) and the pawl (B), turn the rod (C) to

unscrew it from the piston (D), then remove it completely from the burner body.

- Unscrew the screw (R) and the screw (S) from the lung (P);

- pull out the entire mixer unit in the direction shown by the

arrow. When you have finished maintenance work, proceed to reassemble the combustion head, following the same procedure in reverse, after checking the correct position of the ignition electrodes (0002937182стр. 19).

BURNER USE

Burner's operation is fully automatic; it starts up by enabling the master and the control panel switch. Correct burner operation is regulated by command and control devices, as described in the chapter "Operation description". The "lock" position is a safety position that the burner automatically assumes when a burner or system component is not working properly. It is recommended before starting again the burner "by releasing it" to check for faults in the heating plant before restarting the burner. The burner may stay in the lock position without any time limits. To release it, press the red flashing button on the display of the BT 340 equipment ("ENTER" button). Locking may also be caused by temporary faults; in these cases if it is released, the burner will start up again in a regular way. If locking continue to occur (3-4 times), do not continue with the operation and, after having checked that the fuel arrives to the burner, ask the intervention of the after-sales service in your area.
