1. General information
The installation of an oil-fired system must conform to extensive regulations and requirements. It is there-
fore the duty of the installer to be familiar with all applicable regulations and requirements. Installation,
start-up and maintenance must be performed with utmost care. Fuel oil type EL to DIN 51603 must be
used.
The burner must not be operated in rooms with high levels of air humidity (laundry rooms), dust or corro-
sive vapours.
2. Standard Specifications
Before installing the GIERSCH Series M3 oil burner, please check that al items included in the standard
specifications are present.
Items included in supply:
burner, fixing unit, separate operating instructions, technical information leaflet, flange gasket, one 7-pin
and one 4-pin connector (Wieland connector).
Oil nozzles are not included
in the items supplied.
3. Maintenance and customer service
The complete system should be checked once a year for correct functioning and leaks in accordance
with DIN 4755 by a representative of the manufacturer or other suitably qualified person.
According to DIN EN 267, the repair of components with safety-related functions is not permitted. On the
other hand, parts may be replaced with genuine, equivalent – and where necessary tested – components.
We accept no liability for consequential damage in cases of incorrect installation or repair, the fitting of
non-genuine parts or where the equipment has been used for purposes for which it was not intended.
4. Operating instructions
The operating instructions together with this technical information leaflet must be displayed in a clearly
visible position in the boiler room. It is essential that you enter the address of the nearest after-sales ser-
vice centre on the back page of the operating instructions.
5. Instruction of operating personnel
Faults are often caused by operator errors. The operating personnel must be properly instructed in how
the burner works. In the event of recurring faults, Customer Service should be notified.

9. Installation of flange
The boiler connection plate must be prepared for the connection dimensions specified in "Boiler Connec-
tion Dimensions". The flange gasket can be used as a marking template.
First of all, loosen the size 17 nuts (2) and the cap
nuts on the guide rods. The burner flange complete
with burner pipe can now be pulled forwards over
the guide rods.
If the door opening on the boiler is smaller than the
diameter of the burner blast tube, the burner blast
tube can be removed by rotating the bayonet fixing
after releasing the securing screw (1).
The threads of the fixing screws should be brushed
with graphite before fitting. Align flange and burner
blast tube assembly and tighten screws.
Important:
Boiler designs with a very low front plate or door, or boilers with inverted-flame burners require a
suitably extended mixer. If the oil burner was ordered with an extended mixer, this will already be
fitted.
Otherwise the short burner blast tube and nozzle assembly must be replaced with longer versions. The
standard extension is 200 mm.
10. Service position
The burner can now be fastened to the flange. To do
so push the gasket and burner over the guide rods
and secure by means of cap nuts at the end of the
guide rods.
The burner is now in the service position.
11. Nozzle selection
In the case of two nozzle burners the entire output is distributed via two nozzles. As a rule nozzle 1 assu-
mes the basic load (starting output).
At peak demand nozzle 2 is switched on with the remainder of the oil volume. A different load division may
be required depending on the heat requirement and design of the warm air heater.
Max. control ratio 1 : 2.5
For selection of the correct nozzle size relative to the relevant burner type and boiler output we refer you
to the nozzle selection tables on page 13.

12. Inserting the nozzles
After removing the two M10 nuts (spanner size 17) the
burner can be drawn back on the guide rods. It is now in
the servicing position. Undo the screw and withdraw the
flame ring forwards.
Unscrew the plastic dust screw from the nozzle holder.
When doing so, it is essential to ensure that the sealing
face is not damaged.
Screw in the selected nozzles using a wrench (size 16).
Brace with an open-ended spanner. The flame ring is then
refitted and secured with the screw.
On burner type M 3 the nozzle for start output (1st level)
resides under the ignition electrodes.
13. Ignition electrode
The following spacing dimensions should be maintained
between the nozzle and ignition electrode:
The specified dimensions are for the purpose of control in
the event of any correction being necessary or after an
electrode change.

E. 30.05.01 • G.06.08.07
14. Adjustment of the nozzle assembly (dimension "A“)
The dimension "A" indicates the position of the
nozzle assembly and flame ring in the burner blast
tube taper. With the aid of the presetting table the
burner can be set to the relevant output.
In the case of boilers with a higher/lower furnace
pressure, dimension "A" has to be slightly
increased/decreased.
The position of the cam on the air valve positioning
motor also has to be adjusted.
Higher resistance çhigher setting
Lower resistance çlower setting
Precise adjustment to suit the specific system concerned is essential!
15. Oil connection
The oil line must end close enough to the burner to ensure that the flexible oil hose is not under tension
when connected. Care should be taken to ensure that the burner can easily be moved into the servicing
position.
It is essential that an oil filer is fitted upstream of the oil pump.
The tables for dual/single-pipe installation show the maximum possible piping lengths
dependent upon 3 factors assuming use of fuel oil type EL 4.8 cST.
• Height difference between pump and tank
• Nozzle flow rate or pump type
• Pipe diameter
The calculated resistance for the supply lines include allowance for 4 elbows, 1 valve and 1 check valve
for the resistance.
The measure "X" should not exceed a length of 4 m, because of eventual degasifications of the oil.

16. Oil pump
The pumps are intended for installation in a dual-pipe system (factory setting).
The pump pressure must be set for the output required (see Adjustment Table, page 13).
The specified pump pressures are only guide values and may deviate depending on plant conditions.
For this:
• Unscrew pressure testing connection 6.
• Screw in pressure gauge
Set the pump pressure by adjusting the pressure in accordance with the tables.

Remove the return pipe and connection fitting. Uns-
crew the bypass plug from the return pipe connec-
tion and seal off with a plug. The intake volume of the
pump is then the same as the nozzle flow rate.
1 = feed line
2 = return line
3 = nozzle output
4 = pressure adjuster
6 = pressure meter connection
7 = vacuum meter connection
For conversion to a single-line system we recom-
mend the use of a heating oil filter with return line
feed. In this way the pump is left in two-line mode. Fit
the feed and return line burner hoses to the filter.
Open the oil cock on the filter. Put the plant into ope-
ration.
17. Electrical connection
The burner must be connected to the electricity supply in accordance with the wiring diagram. This wok
must be performed by trained, qualified electricians. The supply cable to the burner must be of the flexible
type. Circuit diagram on pages 15-16.
To get to the control elements the cover hood has to
be removed and placed in the servicing position. Re-
move the 4 securing screws in the sides and engage
the cover in the long thread above the flange faste-
ners for the burner motor.
Caution !When performing any connection
work or removing electrical parts
always turn the main switch to “Off” and remove the fuse.

Upon completion of the connection work check the
wiring and briefly actuate the motor contactor with an
electrician's insulated screwdriver to check the direc-
tion of rotation of the burner motor (not on the star-del-
ta version, though).
The direction of rotation is correct if the fan turns to-
ward the boiler (see the arrow on the motor flange).
Information !
The cable for the external burner connections (mains
cable, control and safety thermostat) can be routed
through the cable leadthroughs behind the mounting
plate and wired to the connector block (see Circuit
diagram on pages15-16).
Make sure that the outer sheaths of the cables are
stripped back at least as far as the rear edge of the
mounting plate.
IMPORTANT !
The motor protection relay is set ex-factory to 7.2 A (M3.12) and with a star-delta circuit to 5-5.7 A
(M3.12, M3.22, M3.32).
During commissioning ensure that this value is actually set.
18. Air flap positioning motor
The air valve positioning motor adjusts the air valve
position or trips the solenoid valve on two-level bur-
ners with air shut-off. Adjustment is via limit switch
cams on the positioning drive roller.
You can refer to the presetting table for the cam posi-
tions for adaptation of the burner to the requisite boiler
output.
To do so:
Remove cover from air valve positioning motor. Chan-
ge cam positions with aid of adjusting key. The adju-
sting key is located on the side of the air flap
positioning motor.
If necessary, switching cams can be adjusted when
setting the burner.
Higher setting = More air, pressure increases
Lower setting = Less air, pressure decreases
Star-delta circuit version

11
E. 30.05.01 • G.06.08.07
Please note the following when adjusting the switch cams:
– Do not set cam position for ST1 higher than ST2.
– Set cam position MV2 roughly 10°-20° above cam position ST1.
– Check cam position for MV2 after correcting cam position for ST1.
– After adjusting ST1 and ST2 you have to switch to the next level in order to activate the new setting.
– When adjustment of the burner is complete, refit positioning motor cover and set switch on cover to position
for level 2.
19. Automatic oil firing control device
The automatic oil firing control devices are designed for the control and monitoring of the burners.
The function of the automatic control device is effected via a control program.
– Automatic oil firing device Landis&Gyr LAL 1.25 for all burner types M 3.
20. Functional diagram
1= waiting time 2= preflushing time 3= pre-ignition time 4= safety time 5= post-ignition time
21. Flame failure controller
The flame sensors indicate to the control device the presence of a flame.
The flame failure controller QRB 3 complete with protection pipe must be inserted into the fastening flange
provided for this purpose – Take heed of the guide groove ! In addition the correct position is defined by
a metal clip.
22. Operability check
A safety check of the flame failure system must be carried out when the appliance is first commissioned
and after any inspections or long periods of inactivity.
Start-up test with flame detector covered:
After expiry of the safety period, the burner should perform a safety cut-out.
Start-up test with flame detector illuminated:
After approx. 20 s of pre-aeration the burner must go over to fault.
Standard. Startup; if burner in operation, darken the flame sensor:
Attempt startup again, at the end of the safety time the burner must go over to fault.

23. Start-up
• Screw in oil pressure gauge for measuring pump pressure.
• Preset the burner in accordance with the nozzle selection table on page 13 to the appropriate boiler out-
put.
– Nozzle size
– Dimension "A“
– Air valve position for level 1/level 2
• Connect burner to boiler interface.
• Switch on burner.
• Burner starts up with open air flap (pre-aeration Position 2nd level) .
• Upon completion of pre-aeration the air flap runs to 1st level position and opens solenoid valve 1.
• The burner ignites in level 1.
• Set the burner by means of the switch on the hood to the 2nd level and check the pump pressure.
Then set it again, if necessary.
• Carry out check of CO2content, flue gas temperature and sooting characteristics.
• Correct the blower air via the air valve positioning motor, see page 10
• After regulation of level 2, set the switch to level 1.
• Carry out check of CO2content, flue gas temperature and sooting characteristics.
• Correct the blower air via the air valve positioning motor, see page 10
• When burner adjustments are complete, re-fix cover on air valve positioning motor.
• Switch off burner and remove oil pressure gauge.
24. Faults
Burner faults are signalled by the fault lamp lighting up. If a fault cut-off occurs during burner operation,
check the following first of all:
• Is fuel present
• Are the control and safety devices such as
temperature controller
safety thermostat
water deficiency safety device and
limit switch correctly set and operable ?
Should the fault cut-off still be pending, the functions on the burner must be precisely checked.
Apart from the possible defects already mentioned, burner faults can also have the following causes:
• Ignition spark not in the right place.
• Oil cock closed.
• Oil pump defective or oil filter blocked.

25. Control device Landis&Gyr LAL 1.25
In the event of faults the programming mechanism always stops. The symbol above the indicator's read-
off mark identifies the type of fault:
3No start, e.g., because the CLOSED signal from the end changeover switch «Z» (or auxiliary switch
«M») is missing at terminal 8 or because contact has not been made at terminals 4 and 5.
tAborted startup because the Open signal from the end changeover switch «A» is missing at terminal
8. Terminals 6, 7 and 15 remain live until the fault is rectified !
■Fault cutoff on account of a defect in the flame failure control circuit.
6Aborted startup because the position signal of the auxiliary switch «M» is missing at terminal 8 for the
small flame position. Terminals 6, 7 and 15 remain live until the fault is rectified !
1 Fault cut-off because no flame signal has registered when the safety time expired.
|Fault cut-off because the flame signal has failed during burner operation.
3Fault cut-off upon or after expiry of the control program on account of extraneous light (e.g., non-ex-
tinguished flame, leaking fuel valves or shut-off elements on the nozzle rod, defect in the flame monito-
ring circuit or suchlike).
Unlocking of the automatic control device following a fault cut-off can be effected immediately. After un-
locking, the programming mechanism always runs first of all to its starting position, only terminals 7, 9, 10
and 11 thereby receiving a voltage in compliance with the control program.
Not until after this does the automatic control device effect the programming for putting the burner back
into operation.
Important:
Confirm unlocking for a max. of 20 s !

Example: M3.22
Output: 960kW
Pump pressure: 20bar
Nozzle 1 assumes 2/3 of the total output.
960 x 0.66 ≈640kW ≈54 kg/h
960 x 0.33 ≈320kW ≈27 kg/h
Nozzle 1 = 10.0gph
Nozzle 2 = 5.0gph
By constraint the points of intersection and nume-
rical values differ slightly in practice.
In our example the output of nozzle 1 is therefore
somewhat smaller than calculated.
