Hazard definitions
The following will be used throughout this manual to bring attention to hazards and their risk factors, or to special information.
Denotes presence of a hazard which, if
ignored, will result in severe personal injury,
death or substantial property damage.
Denotes presence of a hazard which, if
ignored, could result in minor personal injury
or property damage.
To the owner —
Installation and adjustment of the burner
requires technical knowledge and the use of
combustion test instruments. Do not tamper
with the unit or controls. Call your qualified
service technician. Incorrect operation of the
burner could result in severe personal injury,
death or substantial property damage.
Have your equipment inspected and adjusted
at least annually by your qualified service

and started only by a qualified service
technician—an individual or agency, licensed
and experienced with all codes and
ordinances, who is responsible for the
installation and adjustment of the equipment.

To the installer —
Concealed damage - If you discover damage
to the burner or controls during unpacking,
notify the carrier at once and file the
appropriate claim.
Contacting Beckett for service information
or parts - Please record the burner serial number
(and have available when calling or writing).
You will find the serial number on the
Underwriters Laboratories label, located on
the left rear of the burner.
High altitude installations — Accepted
industry practice requires no derate of burner
capacity up to 2,000 feet above sea level. For
altitudes higher than 2,000 feet, derate burner
capacity 4% for each 1000 feet above sea
level.

Pre-installation checklist
❏ Combustion air supply
• The burner requires combustion air and ventilation air for
reliable operation. Assure that the building and/or combustion air openings comply with National Fire Protection
Standard for Oil-Burning Equipment, NFPA 31. For appliance/burner units in confined spaces, the room must have
an air opening near the top of the room plus one near the
floor, each with a free area at least one square inch per
1,000 Btu/hr input of all fuel burning equipment in the
room. For other conditions, refer to NFPA 31 (CSA B139M91 in Canada).
• If there is a risk of the space being under negative pressure
or of exhaust fans or other devices depleting available air
for combustion and ventilation, the appliance/burner
should be installed in an isolated room provided with outside combustion air.
❏ Clearances
• With the burner installed in the appliance, there must be
adequate space in front of and on the sides of the burner to
allow access and operation. Verify that the clearance dimensions comply with all local codes and with the appliance manufacturer's recommendations.
❏ Fuel supply
• The fuel supply piping and tank must provide #1 or #2
fuel oil at pressure or vacuum conditions suitable for the
fuel unit (oil pump) on the burner. Refer to fuel unit literature in the literature envelope in the burner carton to verify
allowable suction pressure.
❏ Vent system
• The flue gas venting system must be in good condition
and must comply with all applicable codes.
❏ Electrical supply
• Verify that the power connections available are correct for
the burner. All power must be supplied through fused disconnect switches.
❏ Verify burner components —
• Burner box, Model CF500 and CF800
• Air tube assembly (selected per following)
• Mounting flange kit
• Pedestal mounting assembly kit (recommended)
• Oil nozzle, per Table 1 — Use only 45° to 70° solid pat-
tern nozzles unless otherwise shown by appliance manufacturer.
Find the required firing rate in the 150 psig column (factory-set fuel unit pressure).
Select the corresponding nozzle from column 1 (Rated
gph @ 100 psig).
Table 1 - Nozzle capacities
The fuel unit is shipped without the by-pass
plug installed for CF500/CF800 ON/OFF
burners. You must install this plug on twopipe systems. DO NOT install the by-pass plug
in the fuel unit if connected to a one-pipe oil
If fuel supply is level with or higher than fuel unit —
• When the fuel unit is not required to lift the oil, the installation is usually suitable for either a one-pipe or two-pipe
oil system. The oil pressure at the inlet of the fuel unit must
not exceed 3 psig.
• See Figure 7 for one-pipe fuel supply installations. See
Figure 8 for two-pipe fuel supply installations.
If fuel supply is below the fuel unit —
• Use a two-pipe oil system when the fuel unit must lift the
oil more than 8 feet if burner is equipped with a B fuel unit.
The return line provided by the two-pipe system is needed
to purge the air from the fuel lines and minimize the
likelihood of air-related problems during operation.
system. Failure to comply could cause fuel
unit seal failure, oil leakage and potential fire
and injury hazard.

❏ Verify firing rate
• Refer to appliance manufacturer’s instructions (if available) for firing rate and nozzle selection. Otherwise, the
maximum recommended firing rate for the burner depends
on the length of the firing chamber and the distance from
the burner center to the chamber floor. Verify that the chamber dimensions are at least as large as the minimum values
given in Figure 1. If the appliance dimensions are smaller
than recommended, reduce the firing rate accordingly.
❏ Verify air tube
• The information in this section may be disregarded if the
air tube is supplied by the appliance manufacturer.
• Tube arrangements available:
CF500: 1.75 to 5.50 GPH
CF800: A Tube — 3.00 to 7.00 GPH
B Tube — 5.00 to 8.00 GPH
• Maximum firing capacity depends on the firebox pressure.
Use Table 2 to verify the correct air tube for the firing rate
required.
• See Figure 2 to verify the correct air tube length and air
tube combination code.
