Initial start−up, inspection and maintenance

Further details regarding the individual steps

To obtain optimum combustion values, the burner must be adjusted with the

boiler heated to operating temperature (min. 60ºC).

Also carry out measurements at base load.

Starting the heating system

Boiler control unit service

instructions

1. Check the heating system pressure

and the oil level in the tank.

2. Open the shut−off valves in the oil

supply lines on the oil tank and on

the filter.

3. Fill the oil suction line and the

filter with fuel oil using a manual

oil suction pump before switching

the burner ON.

4. Switch ON the mains switch

(outside of the boiler room).

5. Switch ON the system ON/OFF

switchBat the control unit.

If fault indicator lampAon the

control unit illuminates, press

reset buttonCon the burner.

5692623GB

Initial start−up, inspection and maintenance

Further details regarding the individual steps (cont.)

Checking the adjustment of the air damper servomotor

The burner is equipped with an air

damper servomotor with adjustable

switch cams used to position the air

damper plus a solenoid valve

control.

During a controlled shutdown, the

burner air damper moves to the

"closed" position, which reduces

cool−down losses.

The switch cams are located under

the cover of the air damper

servomotor. A scale ring is located

adjacent to each switch cam, where

the selected angle of the air damper

can be checked.

The switch cams have the following

function:

ST0 Air damper closed (0º)

Never alter the factory

settings of ST0.

ST1 Air damper position stage1

ST2 Air damper position stage2

MV Solenoid valve stage2

The switch cams for stage1 and 2

are set at the factory.

For factory setting values, see

page38.

The switch cams are adjusted via the

slotted screws in the cams.

Initial start−up, inspection and maintenance

Further details regarding the individual steps (cont.)

Adjusting the oil pressure and checking the vacuum

The oil pressure is preset at the factory according to the oil throughput.

Readjust the oil pressure, if required.

1. Switch OFF the mains isolator and

safeguard against unauthorised

reconnection.

2. Unscrew plug"P"Afrom the oil

pump.

3. Unscrew plug"V"Bfrom the oil

pump.

This allows the oil to drain from

the oil pump.

4. Insert a pressure gauge (range

040bar) and a vacuum gauge

(range 01bar).

Seal the pressure and vacuum

gauges only with copper or

aluminium gaskets or Orings.

Never use tape to seal these

joints.

5. Start up the burner.

The solenoid valve opens.

6. Read off the oil and vacuum

pressures of the pump on the

relevant gauge (vacuum should be

max. 0.35bar given a height

differential of 3m between the oil

pump and the bottom of the tank).

Where vacuum measures higher

than 0.35bar, check the filter for

contamination or check the pipe

run.

Initial start−up, inspection and maintenance

Further details regarding the individual steps (cont.)

7. If required, adjust the oil

pressure at pressure adjusting

screwCfor stage1 andDfor

stage2.

Clockwise ³pressure rises

Anti−clockwise ³pressure falls.

For standard burner settings,

see page38.

8. Check the emission values by

taking an actual measurement

after adjusting the oil pressure.

9. Switch OFF the mains isolator

and safeguard against

unauthorised reconnection.

10. Remove the pressure and

vacuum gauges.

11. Insert plug"P"Aand "V"B.

Check the plug seals for damage

and replace, if required.

12. Start the burner and check the

plugs for leaks.

5692623GB

Initial start−up, inspection and maintenance

Further details regarding the individual steps (cont.)

Adjusting the air volume

The air volume is preset at the factory. If required, adjust the air volume; for

this, first adjust the air volume for stage2 at the blast tube connection.

Starting up the burner may require a fine adjustment.

Readjusting stage2

1. Release locking screwB.

2. Change the position of sensor

plateDinside flame tubeC; for

this, turn knurled nutA:

HClockwise

³greater cross−section

³more air,

HAnti−clockwise

³smaller cross−section

³less air.

Note

For standard burner settings, see

page38.

3. Tighten locking screwB.
