Page 7: Principles Of Operation
PRINCIPLES OF OPERATION The ALM Series burners receive the air for combustion via the air suction chamber. After passing through this air suction chamber, the combustion air enters into the burner and reaches the combustion head mixing point via a fan operating in the volute shaped casing. The mixing point consists of the air diffuser and the combustion head. -

The boiler connection flange (4) may be used a template for the M10 holes. Figure 2 The top view of the burner is shown in Figure 3. In order to connect the burner to the boiler, remove the nut (1) first.

Page 10: Pushing Forward And Pulling Back
Fix the burner by pushing its diffuser group (10) through the boiler connection flange (4) Then loosely fix the nut (1) on the stud (8). (See figure 6). The hinge piece (2) on the burner is coupled with the hinge on the connection flange (4) by aligning with the hinge rod (3).Then nut (1) is tightened (See figure 7). -
Page 11: Electrode Adjustments
Following the connection to the boiler and the pushing forward and pulling back operations, the burner is pulled back from the nozzle holder onto which the nozzle is to be installed is reached. The plastic plug on the nozzle holder is removed and nozzles supplied accessories bag are fitted. -
Page 12: Combustion Head-Diffuser Adjustment
COMBUSTION HEAD-DIFFUSER ADJUSTMENT The combustion head and the diffuser must be properly adjusted in order to ensure efficient combustion. The adjustment values shown below represent average values obtained during testing to the EN 267 requirements. Depending on the different boiler room conditions, the combustion values attained by these adjustments may be improved. - Page 13 Select “Combustion Head-Diffuser Adjustment value” corresponding to the capacity value required. Combustion Head- Diffuser Adjustment Curve is also Based on Capacity. Remove the diffuser group (10) of burner (See figure Figure 13 13)from boiler (See figure 14) with the help of the hinges (2).
- Page 14 Measure the distance between diffuser disc and combustion head (See figure 17), after assembling the combustion head onto the diffuser group, this group removed with the help of hinges. In order to adjust the desired distance, move the combustion head (14) over to the combustion head connecting piece (13) and adjust its distance.

Page 15: Combustion Airflow Adjustment With Air Damper (Lks 160)
COMBUSTION AIRFLOW ADJUSTMENT BY DAMPER MOTOR The combustion air enters in the burner via air suction chamber. A flap in the air suction chamber adjusts this airflow. The air damper actuator in two stage burners operates this air flap. The system consists of a 1 stage airflow adjustment cam, stage airflow adjustment cam and 1 stage to 2... -
Page 16: Airflow Adjustment
COMBUSTION AIRFLOW ADJUSTMENT WITH AIR DAMPER (LKS 160) During operation of the burner, the first stage operation is performed with a reduced air supply. Any airflow adjustment should be made at the start of combustion airflow trial. Check the burner for correct operation at this time. The curves below show the air flap adjustment points as a function of boiler capacity. -

COMMISSIONING Remove the electrics panel cover to allowing access to the power supply cables and boiler thermostat cables via the cable entry unions. Connect the cables as per the wiring diagram (see page 21 and 22). These connections are of split type, and will allow you to connect the phase leads to terminals L1, L2 and L3 and the ground lead to terminal N. -

PUMP PRESSURE REGULATION A pressure gauge is connected at the connection point No. 5 for pressure monitoring. A vacuum gauge is connected at the connection point No. 3 for vacuum monitoring. Any bleeding operation must be performed during the burner operation until the fuel flows without any air bubbles being observed from the pressure gauge connection point when it is loosened slightly. - Page 19 One pipe siphon feed system Nozzle (US GPH) d (mm) H (m) E max. = 20m (E-H) max. = 4,5 m One pipe lift system Nozzle (US GPH) d (mm) H (m) H max. = 4,5 m Two pipe siphon feed system Pump AJ4/J4/E4 AJ6/J6/E6...

MAINTENANCE All adjustments of the burner may be easily made in that part of the burner. This is because the burner can be taken out of the boiler with the help of the hinge system. It can then be re-assembled back into the boiler and fixed (See figure 1). - Page 26 Figure 5 Figure 6 The control unit, contactor, fuse and the LED button may easily be reached (See figure 5) by removing three M5 bolts on the electric panel cover (See figure 6).
