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 ﬁ 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 ﬁ ttings.

WARNING

Incorrect installation, adjustment, or mis-

use of this burner could result in severe personal injury, death, or substantial property damage from ﬁ re, 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 qualiﬁ ed individual or service agency that is:

Licensed or certiﬁ ed to install and provide technical service to oil heating systems.

Experienced with all applicable codes, standards and ordinances.

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 National 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.

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.

WARNING

The inlet and return line pressures must not exceed 3 psig, or pump seal damage and oil leaks could result! See NFP A 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 ﬂ 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 ﬁ ttings, inlet ﬁ lters, gauges and other components. A properly installed vacuum safety valve, such as Suntec PRV-38, having accumulator ef fect and pressure relief to tank is acceptable in the inlet line. Do not use teﬂ on tape or compression ﬁ ttings.

CUTOFF CHECK To check cutoff pressure, dead head a pressure 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.

Remove the shutter tab by using a pair of side cutter pliers and ﬁ le sharp edges ﬂ ush with burner surface. This will permit the shutter to be locked securely.

Install the air shutter using the screw located below the pump. Adjust the shutter to the original air setting and tighten screw securely.

NOTICE

screw, it will interfere with the solenoid on the fuel unit. To install a CleanCut fuel unit on a housing that has two top shut-

ter mounting screw holes, make sure the screw is installed in the hole on the left that is closest to the front of the burner (air tube side).

Other Mounting Installations: The CleanCut Pump with a standard cord set or a PD Timer can be installed on the following burners: Carlin EZ-1, Wayne ’M’, Wayne ’E’, Wayne ’HS’, Ducane ’DM’, or Aero. Ducane ’DR’: 5/16” diameter hole will have to be drilled into the housing through the wire cavity. Weil ’QB’: The valve coil blocks the air shutter screw. Allow enough slack in the cord set in order to pivot the valve coil away from the housing.

On older burners, do not install the top shutter

SYSTEM INSTALLATION REQUIREMENTS

ONE-PIPE SYSTEM

DO NOT Install bypass plug - the shaft seal will rupture!

Connect inlet line to pump inlet. Start burner. Arrange primary burner control for continuous operation during purging. Open bleed valve 1 turn CCW. Bleed unit until all air bubbles disappear. Notice: Hurried bleeding will impair efﬁ cient operation of unit. Tighten bleed valve securely.

The Clean Cut fuel unit may be installed with a Gravity or Lift Oil Supply System. The maximum allowable lift is 8 ft.

IMPORTANT: One pipe installations must be absolutely air tight or leaks or loss of prime may result. Bleed line and fuel unit completely. Bleed for 15 seconds after last air is seen from bleed / gauge port to be certain lines are air free.

WIRING INSTRUCTIONS

SOLENOID WIRING Disconnect power supply before wiring to prevent elec-

trical shock or equipment damage.

Lead wires on these devices are long enough to reach the junction box on most burner installations. Note: check the burner manufacturer’s installation sheets for correct solenoid wiring. (See Figure 5). All electrical work must be done according to local and national codes. (Solenoid 115V, 0.1 amp, 60 HZ)

MAXIMUM 1 PIPE (H)

LIFT: 8FT

TWO-PIPE SYSTEM

Remove 1/16” pipe bypass plug from plastic bag attached to unit. Remove 1/4” plug from return port. Insert by-pass plug. Attach return and inlet lines. Start burner – Air bleeding is automatic. Opening air bleed valve will allow a faster bleed if desired. Return line must terminate 3-4” above supply line inlet. Failure to do this may introduce air into the system and could result in the loss of prime.
