Back cover Before you begin . . . The following resources will give you additional information for your installation. We suggest that you consult these resources whenever possible. Pay particular attention to the appliance manufacturer’s instructions. Appliance manufacturer’s instructions — Always follow the appliance manufacturer’s instructions for burner installation, equipment and setup. 1–800–OIL–BURN — Beckett’s technical services hot-line. — Beckett’s website. Form 6104 BCF-23-R0399 Instruction Manual – Model CF2300A Oil Burner Pre-installation checklist o 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 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. o 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. o 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. 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. o Vent system • The flue gas venting system must be in good condition and must comply with all applicable codes. o Electrical supply • Verify that the power connections available are correct for the burner. All power must be supplied through fused disconnect switches. o 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 pattern 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).
