Pipe length

To correct length of pipes is

calculated by summing up the

length of all vertical and hori-

zontal right sections and bends.

The static suction head will be

the distance between the non-

return valve and the burner’s

pump axle. The depression

must not be greater than 0.45

bar; should it be higher, some

damages could occur to the

pump, with consequent increa-

se in mechanical noises and

,eventually, a failure.

Use only the suitable box wrench provided for this operation to remove the nozzle, taking care to not damage

the electrodes. Fit the new nozzle with the same care.

Note: Always check the position of electrodes after having replaced the nozzle (see illustration). A wrong posi-

tion could cause ignition troubles.

6 - TO NOZZLE

VERIFY:

- That piping system is perfectly sealed;

- That the use of hoses is avoided whenever is possible (use copper pipes preferably);

- That depression is not greater than 0,45 bar, to avoid pump’s cavitation;

- That check valve is suitably designed for the duty;

The pump pressure is set at a value of 12 bar (13 bar Maior P 300.1) during the testing of burners. Before

starting the burner, bleed the air in the pump through the gauge port. Fill the piping with light-oil to facilita-

te the pump priming. Start the burner and check the pump feeding pressure. In case the pump priming does

not take place during the first prepurging, with a consequent, subsequent lock-out of the burner, rearm the

burner’s lock-out to restart, by pushing the button on the control box. If, after a successful pump priming,

the burner locks-out after the prepurging, due to a fuel pressure drop in the pump, rearm the burner’s lock-

out to restart the burner. Do never allow the pump working without oil for more than three minutes. Note:

before starting the burner, check that the return pipe is open. An eventual obstruction could damage the

pump sealing device.

Once having installed the burner, check the following items:

- The burner power feeding and the main line protection fuses

- The correct length of pipes and that the same are sealed.

- The type of fuel, which must be suitable for burner.

- The connection of boiler’s thermostats and all the safeties.

- The motor rotation direction.

- The correct calibration of the motor’s thermal protection.

When all the above mentioned conditions are checked and accomplished, it is possible to go on with burner’s

tests. Power the burner. The control box feeds the ignition transformer and the burner’s motor at the same

time, which will run a prepurging of the combustion chamber for about 20 sec.

At the end of prepurging, the control box opens the fuel pump and the 1st stage (Low flame) solenoid valves,

the ignition transformer produces a spark and the burner ignites. After a safety interval of 5 seconds and a

correct ignition, the control box turns off the ignition transformer and, 10 seconds later, sets the motorised

air damper to its maximum opening and opens the 2nd stage solenoid valve and 3rd stage solenoid valve

(High flame). In case of faulty ignition, the control box switches the burner into safety condition. In such a

case, the manual rearming of the burner shall not take place before 30 seconds have elapsed from the burner’s

safety shutdown. In order to obtain an optimal combustion, it is necessary adjust the LOW - HIGH flame air

flow, according to the instruction given further on. During such a phase, it will be possible to manually swit-

ch between HIGH ( II ) and LOW ( I ) flame and viceversa, through the High/Low flame switch. At the end

of the adjusting phase, leave the switch in position II (HIGH flame).

The fuel pump feeding pressure, must remain around 12 bar.

LANDIS LMO 44 CONTROL INFORMATION SYSTEM

In case of burner lockout, it is possible to read which cause originated it. Proceed as follows: with the burner in lockout

mode (red LED switched on) keep pressed the lockout button for more than 3 sec. then release it. The red LED will blink

according to the following error code list:

Error Code Possible cause

2 blinks No establishment of flame at the end of «TSA»

- Faulty or soiled fuel valves - Faulty or soiled flame detector - Poor adjustment of burner,

no fuel - Faulty ignition

3 blinks Free

4 blinks Extraneous light on burner start-up

5 blinks Free

6 blinks Free

7 blinks Too many losses of flame during operation (limitation of the number of repetitions)

- Faulty or soiled fuel valves - Faulty or soiled flame detector - Poor adjustment of burner

8 blinks Time supervision oil pre-heater

9 blinks Free

10 blinks Wiring error or internal error, output contacts

COMBUSTION AIR FLOW ADJUSTMENT (HIGH-LOW FLAME)

Air flow adjustment in Low Flame (1st Stage):

1 – Open thermostats TAB1 and TAB2 (see wiring diagram).

2 – Start the burner (while checking that air damper is partially open).

3 – Loosen locking screw D.

4 – Manually turn the air dampers until to obtain a correct combustion.

5 – Tighten locking screw D.

Air flow adjustment in High Flame (2nd Stage):

WARNING: When the burner is working in High Flame, the presence of oil under pressure in the hydraulic jack could make difficult the tur-

ning of the adjusting screw 1. As a consequence, the adjustment of fuel flow rate shall be made through said screw with the burner in

Low Flame, whilst the combustion control shall be carried out once switched to High Flame.

1 – Open thermostats TAB1 and TAB2 (see wiring diagram).

2 – Loosen locking ring nut 2.

3 – Increase or decrease fuel flow rate through the adjusting screw 1 (turn clockwise to increase and counterclockwise to decrease).

4 – Tighten ring nut 2.

5 – Manually switch to High Flame by closing thermostat TAB1 and check combustion values.

Air flow adjustment in 3rd Flame (3rd Stage):

WARNING: When the burner is working in 3rd Flame, the presence of oil under pressure in the hydraulic jack could make difficult the tur-

ning of the adjusting screw 3. As a consequence, the adjustment of fuel flow rate shall be made through said screw with the burner in

Low Flame, whilst the combustion control shall be carried out once switched to 3rd Flame.

1 – Open thermostats TAB1 and TAB2 (see wiring diagram).

2 – Loosen locking ring nut 4.

3 – Increase or decrease fuel flow rate through the adjusting screw 4 (turn clockwise to increase and counterclockwise to decrease).

4 – Tighten ring nut 4.

5 – Manually switch to 3rd Flame by closing thermostats TAB1 and TAB2 and check combustion values.

All burners are factory tested at 400V - 50Hz 3-phase for motors, and 230V - 50Hz single phase with neutral

for auxiliary equipments. Should it be necessary to power the burner with 230V - 50Hz, modify the connec-

tions on motor and the terminal board as shown in the picture. Protect the burner supply line with suitable

fuses and/or other safety devices as required by the local regulations on the matter.
