6.17 Heating curve

The heating curve is used to generate the flow temperature setpoint, which is used to maintain a certain flow temperature depending on the prevailing weather conditions.

The heating curve can be adjusted with a number of settings, thus matching heat output and room temperature to individual needs.

As the heating curve slope is raised, the flow temperature increases the quicker the lower the outside temperature or, in other words, if the room temperature is not correct at low outside temperatures but correct at higher outside temperatures, the heating curve slope requires readjustment.

Increase adjustment: Raises the flow temperature, especially when outside temperatures are low.

Decrease adjustment: Lowers the flow temperature, especially when outside temperatures are low.

Default setting 1,5

Parallel displacement of the heating curve is used to change the flow temperature evenly across the entire outside temperature range or, in other words, if the room temperature is always too high or too low, a readjustment must be made with the help of the parallel displacement.

- Press the “OK-button”

- Select “Heating circuit 1” and press “OK”

- Select Menu 720 “Heating curve slope” and press “OK”

- Select setpoint and press “OK” for confirm

- Select Menu 721 “Heating curve displacement” and press “OK”

- Select setpoint and press “OK” for confirm

- Press “ESC” and “ESC” again

6.18 Flow temperature limitation

Using this limitation, a temperature range for the flow temperature setpoint can be defined. If the flow temperature setpoint demanded by the heating circuit reaches the relevant limit and the heat request increases or decreases, the flow temperature setpoint will be maintained at the maximum or minimum limit.

If you want to have floor heating in the summer for example in a basement or a bathroom you set the “Flow temp min” to a higher temperature.

Notice that the value for “Summer/winter setpoint stops the heating circuit at chosen temperature, in “Automatic mode”. So you maybe have to select a higher temperature on this as well.

To select a value for the set points do as follow:


- Press the ”i-button” for 3 seconds.

- Select “Commissioning” and press “OK”.

- Select “Heating circuit 1” and press “OK”.

- Select “Flow temp setpoint min” (Menu 740) and press “OK”

3. INSTALLATION

3.1 Oil supply

3.2 Burner installation

3.2.1 Oil pipes

E

In order to achieve good operational reliability it is important that the oil supply system is laid out correctly.

Observe the following:

- Choice of pipe diameters, pipe lengths and height differences (refer to pump instructions).

- Piping should be run with a minimum of joints/compression fittings.

- Pipework must be laid out so that oil hoses are not subjected to tension or overbending when the burner is swung out or removed for service.

- The oil filter should be installed so that the filter cartridge can easily be replaced

1. Check the oil pipe dimensions. (Refer to Pump Instructions.)

2. The oil filter should be installed in the oil supply line. If an air separator is fitted, the oil filter should be installed before the air filter to increase the life span of the filter.

3. For one-pipe systems the return plug must be removed. (Refer to

Pump Instructions.)

4. When installing oil hoses, check that the supply and return hoses are connected to the correct connections on the oil pump. The hoses must be run so that they are not bent or tensioned.

5. Purge the oil system. The oil pump will be damaged if it is run dry.

6. The vacuum should not be lower than 0.3 bar depression in the suction line at start up.

4. BASIC SETTINGS

4.1.1 Nozzle assembly adjustment

Brake plate setting

The burner is fitted with a regulator which changes the brake plate position in the blast tube. This is used to set the correct pressure drop across the combustion assembly and thereby achieve good combustion without pulsation. The setting to be chosen is dependent among other things on set output and furnace pressure.

- Less diffusion: turn screw to left.

- More diffusion: turn to right.

Setting brake plate position affects air flow. It is therefore always necessary to adjust the air with the burner air regulator afterwards.

4.1.2 Air intake adjustment

Air settings are very important for achieving good combustion with neither too much, nor too little, air. Adjustment of combustion airflow is carried out by turning the air regulator with a hex key. How far open the air regulator must be is determined by output, furnace pressure and other burner settings such as blast tube position.

4.1.3 Method of adjusting air quantity

Setting the air regulator is dependent on how the screw (with which air regulation is adjusted) is installed. If the air intake is installed underneath as shown in the illustration, turning the screw clockwise will reduce airflow, and anticlockwise increase it.

6.1.4 Function BFP 21 LE-S

6.1.5 LE-S System

6.1.6 Purging

When the pump is started, oil is drawn from the suction port (S) through the filter (H) to the suction port (C) of the gear-set.

The oil then moves to the pressure side of the gearwheel and is thus pressurised. The pressure is controlled and maintained at a constant preset level by diaphragm (D) of the control valve (P

The control valve (P

1

1

)

) distributes the oil supplied by gear-set (C) between the nozzle connection (E) and the return port of the pump (R).

The amount of oil consumed is determined by the pressure set on the control valve (P

1

) and by the size of the oil nozzle in the nozzle line.

The control valve (P

1

) operates as follows:

- When the oil attains opening pressure, the port to the return side opens.

- The diaphragm and the spring keep a constant pump pressure at the set value.

- If the pump becomes overloaded, i.e. if an attempt is made to take out more oil than the gear-set can deliver in the prevailing circumstances, the oil pressure will fall below the set value causing the valve to close, by diaphragm (D), to the return port (R) and return to the starting position.

This can be remedied by:

- Lowering the pump pressure.

- Reducing the amount of oil delivered, ie, changing to a smaller nozzle.

- Changing to a pump with higher capacity.

The check valve B allows the oil trapped between solenoid valve NC and the LE valve in the preheater to expand backwards in the system to the return port.

The cut-off valve does not cause any extra pressure drop, i.e. at a pump pressure of 10 bar the spraying pressure will also be 10 bar.

Note!

The LE-S pump has an integrated check-valve function at the solenoid valve, allowing the oil pressure to expand backwards during standstill.

The desired function of avoiding the formation of drops on the nozzle can only be achieved by using both the LE-S pump and the LE valve built into the FPHB-LE preheater.

The system is only used on the BFP pump fitted with a solenoid valve.

The pumps are given a different designation, e.g. BFP 21 LE-S, but do not differ on the outside from the normal BFP pump.

BFP LE-S pumps cannot be converted into standard pumps, and the standard BFP pump cannot be converted to the LE-S system.

The LE valve must be fitted when using the LE-S pump. The LE valve may not be excluded unless a BFP standard pump without the LE-S function is used instead.

Purging air is only necessary in single-pipe systems. In two-pipe systems the pump purges air automatically through the return line.

The suction line tables comprise theoretically calculated values where pipe dimensions and oil flow are adapted to prevent turbulent flows from occurring. Turbulent flows can result in pressure losses and noise in the pipework.

A typical pipe system usually comprises pipe runs with 4 bends, a nonreturn valve, a shut-off valve and a pre-filter.

The total resistance of these items is such that it can be disregarded. In the tables no run longer than 100 m is listed, as experience shows this not to be required.

The tables apply to standard heating oil of normal grade merchantable according to existing norms. When starting operations with an empty pipe system, the pump should not be run without oil for more than 5 min. (This presupposes that the pump is lubricated with oil when running.)

The tables give the total suction line length in meters with a nozzle capacity of 2.5 kg/h. Max. permissible pressure on the suction and pressure lines is 2.0 bar.

8. PREHEATER

8.1.1 Function FPHB 5-LE

8.1.1.1 LE-valve

When the boiler thermostat connects, the PTC element is energized and oil begins to preheat. When the oil has reached the correct temperature, the preheater thermostat closes and the burner receives the start signal.

During operations the PTC element compensates its output so that the temperature does not become too high. If the oil temperature is low and the oil flow high, the preheater thermostat may open owing to the PTC element’s inability to maintain oil temperature. In this case it is important to use oil burner controls with a preheater holding circuit.

FPHB 5-LE has an integrated shut-off valve which prevents oil drips at start and stop. When a normal preheater is used before start, the oil expands and a small quantity of oil flows out of the nozzle orifice and wets the outside of the nozzle. Also, when the burner stops, a small quantity of oil forces its way out after the flame has gone out, especially when there are hot components which radiate heat back to the nozzle. The cutoff valve in the FPHB 5-LE is located immediately behind the nozzle. It opens at ≈ 6.5 bar and closes at ≈ 2.5 bar.

In order to achieve the intended effect when the pressure of the trapped oil increases, it must be evacuated back to the pump. This is made possible by the pump solenoid valve’s return-valve function.

The cut-off valve can be pulled out of the preheater with the aid of an M5 screw as illustrated. When the valve is re-installed, oil pressure pushes it to a position all the way forward behind the nozzle filter so that the volume in front of the valve is as small as possible.

Operations switch ON, thermostat ON

The burner motor starts, ignition sparks initiated and pre-ventilation continues until the set pre-ventilation period is over and the solenoid valve (2) opens.

1b.

Operations switch ON, thermostat ON

The preheater is energized and the pre-heating period begins. This continues until the operating temperature is reached and the preheater thermostat closes. The burner motor starts, ignition sparks initiated and pre-ventilation continues until the set pre-ventilation period is over and the solenoid valve (2) opens.

Solenoid valve opens

The oil mist is formed and ignited. The photocell indicates flame. The ignition spark ceases 15 sec. after flame indication.

Safety period runs out

If the flame is not present before the end of this period, the oil burner control blocks further operation.

If the flame for any reason disappears after this time period, the burner will make a new start attempt.

4-5 During operation

If burner operations are interrupted via the main switch or thermostat, a new start will be initiated when conditions according to point 1 are fulfilled.

Oil burner control blocks

Red light on the oil burner control illuminates. The burner is re-started by pressing the reset button.
