Denotes presence of a hazard which, if ignored, could 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 technician to assure continued proper operation.

Never attempt to use gasoline in your heating appliance or to store gasoline or combustible materials near the heating equipment. This could result in an explosion or fire, causing severe personal injury, death or substantial property damage.

Intended to bring special attention to information, but not related to personal injury

or property damage.

To the owner —

Never burn garbage or refuse in your heating appliance or try to light the burner by tossing burning material into the appliance. This could result in severe personal injury, death or substantial property damage.

Never attempt to use crankcase or waste oil in your heating appliance. This could damage the fuel unit or heating equipment, resulting in risk of severe personal injury, death or substantial property damage.

Never restrict air openings on the burner or to the room in which the appliance is located. This could result in fire hazard or flue gas leakage, causing severe personal injury, death or substantial property damage.

To the installer —

Read all instructions before proceeding. Follow all instructions completely. Failure to follow these instructions could result in equipment malfunction, causing severe personal injury, death or substantial property damage.

This equipment must be installed, adjusted 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. The installation must comply with all local codes and ordinances and with the National Fire Protection Standard for Oil-Burning Equipment, NFPA 31 (or CSA B139-M91).

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.

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.

50 Hz motors — The burner ratings, air settings and nozzle ratings are based on standard 60 hz motors (at 3450 rpm). Derate all ratings 20% when using 50 hz motors. Consult factory for specific application data.

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 NFP A 31 (CSA B1139M91 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.

❏ 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 CF2300A

• 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 300 psig column (high fire rate). Select the corresponding nozzle from column 1 (Rated gph @ 100 psig).

❏ 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 b urner carton to verify allowable suction pressure.

When fuel supply is level with or higher than burner 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.

• The fuel unit is shipped with the by-pass plug installed.

Leave the by-pass plug installed for all low/high firing burners, regardless whether one-pipe (with by-pass loop) or two-pipe. See Figure 8 for installation of the by-pass loop required for one-pipe fuel supply installations. See

Figure 9 for connections to the fuel unit for two-pipe fuel

supply installations.

When fuel supply is below the burner 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 — or more than 2 feet if burner is equipped with an H 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.

Note: 10% turndown indicates sufficient reserve air to reduce th e CO2 in the

Note:

The above ratings may vary 5% due to variations in actual job conditions.

❏ 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.

• Two tube arrangements are available –

Tube KG — 7.0 to 19.9 GPH per Table 2 Tube KS — 10.0 to 19.9 GPH per Table 2

• Maximum firing capacity depends on the firebox pressure. Use Table 2 to verify the correct air tube type for the firing rate required. Use Tube KS only when Tube KG cannot provide the firing rate required.

• See Figure 2 to verify the correct air tube length and air tube combination code.
