Beckett Burner ADC Manual De Usuario

General Pump Information
Important information - Long or oversized inlet lines may 
require the pump to operate dry during initial bleeding 
period. In such cases, the priming may be assisted 
by injecting fuel oil in the pump gear set. Under lift 
conditions, lines and fi ttings must be air tight. To assure 
this, “Pipe Dope” may be applied to both the used and 
unused inlet and return fi ttings. Do NOT use Tefl on tape 
or compression fi ttings
Mounting Position - Beckett CleanCut pump may be 
mounted in any position (except upside-down in a  single 
pipe installation).
Vacuum Check - A Vacuum Gauge may be installed in 
either of the 1/4” NPT inlet ports.
Pressure Check- When a pressure check is made, use 
the nozzle port. If the bleed port is used, the reading on 
the gauge should be approximately 5 psig higher than the 
pressure reading on the nozzle port. See Figure 8.
Cutoff Check - To check cutoff pressure dead head a 
pressure gauge in the nozzle port. Run the burner for a 
short period of time. Shut the burner off. The pressure 
will drop and hold above zero. Pressurized or gravity feed 
installations must not exceed 3 psig on inlet line or return 
line at the pump per NFPA 31. A pressure greater than 10 
psig may cause damage to the shaft seal.

To determine if the valve coil requires replacement perform 
the following steps.

1.  Remove the cord set from the valve.
2.  Place the leads from an ohmmeter across the coil.
3.  A 12Vdc volt coil should measure between 15 and 

25 ohms.

4.  If the meter indicates an open circuit, replace the coil.

To check pump operation perform the following.

1.  Check the operating pressure by removing the copper 

tubing from the nozzle line and installing a pressure 
gauge in the line. With the motor running and the coil 
energized, check the gauge. The pressure should read 
100 psig unless otherwise stated.

2.  To check the cutoff function, deadhead the pressure 

gauge onto the copper connector tube attached to the 
nozzle port. Run the burner for a short period of time. 
Shut the burner off; the pressure should drop and hold.

To replace the coil and/or pump assembly perform the 
following steps.

1.  Before servicing, turn off and/or disconnect all power 

to the burner.

2.  Remove the copper tube assembly when replacing 

the pump or when removing the coil and the tube 

blocks the coil.

3. Using a fl at tip screwdriver, press the fl at tip into the 

spring washer to prevent it from rotating.

4.  Using a 10mm wrench or adjustable wrench, remove 

the nut and spring washer.

5.  Remove the coil by lifting it straight up.
6.  Remove the two base plate screws, then the base 

plate by lifting straight up.

7.  Remove valve stem assembly by pulling straight up.
8.  To install the new stem and coil assemblies, follow 

the above steps in reverse order, tightening each 

part as you go.

9. Restore power, start the burner and perform 

the combustion test described previously in this 

manual.

Typical Constant Duty Ignition Confi guration - With 
this Beckett ADC oil burner confi guration, the motor 
and igniter operate continuously while the valve that 
controls oil fl ow is cycled by the switches on the power 
washer.  The motor is used to drive the blower and pump. 
The rotational speed of the motor is determined by the 
voltage supplied and the load placed on the motor.  Pump 
pressure and air settings are the main factors affecting 
the motor load. The igniter converts battery DC voltage 
into a high voltage spark to ignite the oil. The igniter is 
capable of running continuously as long as the blower 
wheel is circulating air across the igniter base.  The pump 
and solenoid valve are used to control the fl ow of oil from 
the reservoir to the nozzle.
