Beckett 24 VDC Manuel D’Utilisation

24 Vdc SDC Burner Manual

Have your equipment inspected at regular intervals 
by a qualifi ed service agency to assure continued 
proper operation. The burner should be adjusted using 
dedicated combustion test equipment. Failure to properly 
set the burner could result in ineffi cient operation, and/or 
conditions that could potentially cause severe personal 
injury, death or substantial property damage.

Properly installed and maintained, your SDC burner will 
provide years of effi cient, trouble-free operation. Please 
take care of your equipment by following the warnings 
provided and by immediately contacting your qualifi ed 
service agency, if your burner is not operating properly. 
This equipment should be serviced only by a qualifi ed 
service agency. The appropriate test instruments must be 
used. 

Check the area around your burner/equipment to make 
sure: 

Nothing is blocking the burner inlet air openings.
Air ventilation openings are clean and unobstructed 
and the exhaust is not crusted.
No combustible materials are stored near the 
equipment.
There are no signs of oil or water leakage around 
the burner or equipment.

If the equipment will be stored for an extended period of 
time, ensure the fuel tank is full and add a fuel stabilizer 
to the tank.

Use only Beckett replacement parts 

for continued safe operation of the 

burner.

Have your burner, serviced annually by your qualifi ed 
service agency. The following components/assemblies 
should be checked/adjusted/replaced on a regular basis. 

Refer to the Replacement Parts exploded view for part 
locations.

Replace the oil supply line fi lter,  if  applicable. 

The line fi lter cartridge must be replaced to avoid 

contamination of the pump and nozzle.
Inspect the oil supply system. All fi ttings should be 

leak-tight. The supply lines should be free of water, 

sludge and other restrictions.
Remove and clean the pump strainer.
Verify the nozzle is the one originally specifi ed by the 

appliance manufacturer and replace the nozzle with 

one having the exact specifi cations from the same 

manufacturer.
Clean and inspect the electrodes for damage, 

replacing any that are cracked or chipped.
Check electrode tip settings. Replace electrodes if 

tips are rounded.
Inspect the igniter spring contacts. Clean or replace 

if corroded.
Clean the cad cell, if applicable.
Make sure Low Firing Rate Baffl e is in place, if 

required, for the burner application.  Omitting the baffl e 

can result in unacceptable burner combustion.
Inspect all gasket including the igniter base plate 

gasket.  Replace any that are damaged or missing.

Allow the burner to run for approximately 5 to 10 
minutes.
Follow these four steps to properly adjust the 
burner:

Step 1: Adjust the air until a trace smoke level is 

achieved.

Step 2: At the trace of smoke level, measure the 

CO

2

 (or O

2

). This is the vital reference 

point for further adjustments.

Step 3: Increase the air to reduce CO

2

 by 1 

percentage point (O

2

 will be increased by 

approximately 1.4 percentage points).

Step 4: Recheck the smoke level. It should be zero.
 
This procedure provides a margin of reserve air to 
accommodate variable conditions.
Once the combustion level is set, tighten the fasteners 
on the air band and air shutter.
Start and stop the burner several times to ensure 
satisfactory operation. 
Test the equipment safety controls to verify that 
they function according to the manufacturer’s 
specifi cations.
