Beckett CF1400 manual Oil Supply Pressure Control Required, Correct Nozzle and Flow Rate Required

‰Fuel supply

Oil Supply Pressure

Control Required

Damage to the filter or pump seals could cause oil leakage and a fire hazard.

yThe oil supply inlet pressure to the burner cannot exceed 3 psig.

yInsure that a pressure limiting device is installed in accordance with the latest edition of NFPA 31.

yGravity Feed Systems: Always install an anit-siphon valve in the oil supply line or a solenoid valve (RWB Part # 21789) in the pump/nozzle discharge tubing to provide backup oil flow cut-off protection.

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 9 for installation of the by- pass loop required for one-pipe fuel supply installations. See Figure 10 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. The return line provided by the two-pipe system is needed to minimize the effects of air-related problems during operation.

‰Nozzle pressure

Correct Nozzle and Flow

Rate Required

Incorrect nozzles and flow rates could result in impaired combustion, under-firing, over-firing, sooting, puff-back of hot gases, smoke and potential fire or asphyxiation hazards.

Use only nozzles having the brand, flow rate (gph), spray angle and pattern specified by the appliance manufacturer.

Follow the appliance manufacturer’s specifications for the required pump outlet pressure for the nozzle, since this affects the flow rate.

yNozzle manufacturers calibrate nozzle flow rates at 100 psig.

yThis burner utilizes pressures higher than 100 psig, so the actual nozzle flow rate will be greater than the gph stamped on the nozzle body. (Example: A 8.00 gph nozzle at 150 psig = 9.80 gph and at 300 psig = 13.86 gph)

For typical nozzle flow rates at various pressures see accompanying chart.

yThe fuel unit nozzle port pressure is factory set at 300 psig. Some original equipment manufacturer burner applications may call for a lower pressure to obtain a required firing rate. Do not change this pressure un- less directed to do so by the appliance manufacturer.

‰Electrical supply

Verify that the power connections available are correct for the burner. Refer to Figure 1. All power must be supplied through fused disconnect switches.
