Beckett Burner ADC Manual De Usuario

12 Vdc ADC Burner Manual

 

y

Do not attempt to start the burner when excess oil has 

accumulated in the appliance, the appliance is full of 

vapor, or when the combustion chamber is very hot.  

 

y

Do not attempt to re-establish fl ame with the burner 

running if the fl ame becomes extinguished during 

start-up, venting, or adjustment.

y

Vapor-Filled Appliance: Allow the unit to cool off 

and all vapors to dissipate before attempting another 

start. 

y

Oil-Flooded Appliance: Shut off the electrical power 

and the oil supply to the burner and then clear all 

accumulated oil before continuing.

 

y

If the condition still appears unsafe, contact the Fire 

Department. Carefully follow their directions. 

 

y

Keep a fi re extinguisher nearby and ready for use.

Igniter with Interrupted Duty Ignition - This optional 
control circuit is available to reduce current draw on the 
charging system by turning the igniter off after a fl ame has 
been established. This option controls igniter operation 
based on a signal from a light sensing cad cell. When light 
hits the cell the control will sense a decrease in resistance 
across the sensor. A few seconds delay will occur prior 
to the igniter switching off. As long as suffi cient light is 
reaching the cell eye, the igniter will remain off. If light is 
removed from the sensor, the igniter will turn on until light 
is again sensed by the cad cell.

With 7556 Primary Safety Control - The 7556 control 
provides the same benefi ts as the ignition control board 
as described above as well as added safety, convenience, 
and performance features. It adds a valve on delay and 
motor-off delay to the burner’s operation sequence that 
promote clean burner operation. It has a lock-out function 
that shuts the burner down if it is not operating properly. 
The control adds fusing at the burner to protect against 
component failures. The control also has redundant motor 
relays that are checked for proper operation every heat 
cycle.

Variations to the burner circuits may occur due to optional 
temperature, pressure, and vacuum switches that control 
burner operation. Note that when external switches 
are used to control motor operation they must be sized 
correctly for the rated current or a relay should be installed 
to isolate the switches from the motor’s full load current.

As soon as burner motor starts rotating bleed all the air 
from the pump. (Required with single-pipe systems.)

To bleed the pump, attach a clear plastic hose over the 
vent fi tting. Loosen the fi tting and catch the oil in an empty 
container. Tighten the fi tting when all air has been purged 
from the supply system. Note: If the burner stops after a 
fl ame is established, the unit probably requires additional 
bleeding. Continue to bleed the system until the pump is 
primed and a fl ame is established when the bleed valve 
is closed.

1.  Allow the burner to run for approximately 5 to 10 

minutes.

2. 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. 

3.  This procedure provides a margin of reserve air to 

accommodate variable conditions.

4.  Once the combustion level is set, tighten the fasteners 

on the air band and air shutter.

5.  Start and stop the burner several times to ensure 

satisfactory operation. 

6. Test the equipment safety controls to verify 

they function according to the manufacturer’s 
specifi cations.
