INSTALLATION INFORMATION
INSTALLATION INFORMATION
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 ttings must be
air tight. To assure this, oil-resistant pipe joint compound may be
applied to both the used and unused inlet and both return ttings.

Please read and understand the manual supplied with this equip-
ment. This equipment must be installed, adjusted and put into
operation only by a quali ed individual or service agency that is:
Licensed or certi ed to install and provide technical service
to oil heating systems.
Experienced with all applicable codes, standards and ordi-
nances.
Responsible for the correct installation and commission of
this equipment.
Skilled in the adjustment of oil burners using combustion
test instruments.
The installation must strictly comply with all applicable codes,
authorities having jurisdiction and the latest revision of the Na-
tional Fire Protection Association Standard for the installation of
Oil-burning Equipment, NFPA 31 (or CSA-B139 and CSA-B140
in Canada).
Regulation by these authorities take precedence over the general
instructions provided in this installation manual.

WARNING
!
Oil Leak & Fire Hazard
WARNING
!
The inlet and return line pressures must not exceed 3 psig,
or pump seal damage and oil leaks could result! See NFPA
31-25, 8.6.3.
Do not use a check valve in the inlet line of a 1-pipe system
(with or w/o a boost pump), or in the return line of a 2-pipe
system.
NFPA 31-25, 8.5 states that ‘A return line from a burner or
pump to a supply line shall have no valves or obstructions
and shall enter the top of the same tank.’
Check valve ow restriction in a return line can elevate
pressures and damage the fuel unit seals.
Dangerous thermal expansion of oil trapped by an inlet
line check valve can create extreme pressures that damage
fuel unit seals, line ttings, inlet lters, gauges and other
components. A properly installed vacuum safety valve, such
as Suntec PRV-38, having accumulator effect and pressure
relief to tank is acceptable in the inlet line.
Do not use te on tape or compression ttings.

CAUTION
MOUNTING POSITION Beckett CleanCut fuel unit may be
mounted in any position (except upside-down during single pipe
installation).
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.
