Oil Supply Pressure Control Required | Beckett 800, CF500 manual

Fuel supply

Oil Supply Pressure

Control Required

Damage to the pump, ﬁlter or other compo- nent seals could cause possible oil leakage and potential ﬁre hazard.

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

yDo NOT install valves in return line.

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

yThe 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.

If fuel supply is level with or higher than fuel unit —

yWhen 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.

yRefer to the Mount the Burner Section of this manual for one-pipe or two-pipe fuel supply installation instructions.

If fuel supply is below the fuel unit —

yUse 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.

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 4.00 gph nozzle at 140 psig = 4.70 gph.

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

yThe fuel unit nozzle port pressure is factory set at 140 psig. Some original equipment manufacturer burner appli- cations may call for a lower pressure to obtain a required ﬁring rate. Do not change this pressure unless directed to do so by the appliance manufacturer.

Electrical supply

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

Vent system

y The ﬂue gas venting system must be in good condition and must comply with all applicable codes.
