BECKETT CLEANCUT INSTALLATION INFORMATION
SINGLE STAGE FUEL UNIT
Part No. 21844
GENERATION INFORMATION - ALL SYSTEMS
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 gearset. Under lift conditions, lines and fittings must be air tight. To assure this,
! WARNING Professionalquired Service Re-
Incorrect installation, adjustment, or mis- use of this burner could result in severe personal injury, death, or substantial prop- erty damage from fire, carbon monoxide poisoning, soot or explosion.
Please read and understand the manual supplied with this equip- ment. This equipment must be installed, adjusted and put into operation only by a qualified individual or service agency that is:
yLicensed or certified to install and provide technical service to oil heating systems.
yExperienced with all applicable codes, standards and ordi- nances.
yResponsible for the correct installation and commission of this equipment.

Regulation by these authorities take precedence over the general instructions provided in this installation manual.
!WARNING Oil Leak & Fire Hazard
yThe inlet and return line pressures must not exceed 3 psig, or pump seal damage and oil leaks could result! See NFPA
yDo not use a check valve in the inlet line of a
yNFPA
yCheck valve flow restriction in a return line can elevate pressures and damage the fuel unit seals.
yDangerous thermal expansion of oil trapped by an inlet line check valve can create extreme pressures that damage fuel unit seals, line fittings, inlet filters, gauges and other components. A properly installed vacuum safety valve, such as Suntec
yDo not use teflon tape or compression fittings.

MOUNTING POSITION Beckett CleanCut fuel unit may be mounted in any position (except
VACUUM CHECK A Vacuum Gauge may be installed in either of the 1/4” NPT inlet ports. The Beckett CleanCut pump should be used where the vacuum does not exceed 6” hg. single pipe and 12” hg. two pipe. The Beckett CleanCut XL pump should be used where the vacuum is less than 17” hg. Remember, running vacuum is the total of all pressure drops (eP) in the system from tank to inlet of pump.
PRESSURE CHECK When a pressure check is made use either the BLEED PORT OR NOZZLE PORT.
CUTOFF CHECK To check cutoff pressure, dead head a pres- sure gauge in nozzle port. Run burner for short period of time. Shut burner off. The pressure will drop and hold above zero.
MOUNTING PUMP (If the shutter screw interferes with the solenoid on the fuel unit)
To install a CleanCut fuel unit on chassis with existing shutter tab see Figure 2 and follow these steps:
Remove existing fuel unit and solenoid valves, if applicable, and appropriately dispose of them.
Note the air setting of the shutter, then remove the air shutter, set the shutter aside to be reinstalled.
