• The oil supply inlet pressure to the fuel unit cannot exceed 3 psig. • Do NOT install valves in return line. • Ensure that a pressure-limiting device is installed in accordance with the latest edition of the NFPA 31. • 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. 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. • Refer 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 — • 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. • Nozzle pressure Correct Nozzle and Flow Rate Required Incorrect nozzles and flow rates could result in impaired combustion, underfi ring, 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 specifi cations for the required pump outlet pressure for the nozzle, since this affects the fl ow rate. • Nozzle manufacturers calibrate nozzle flow rates at 100 psig. • This 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. • For typical nozzle flow rates at various pressures see accompanying chart. • The fuel unit nozzle port pressure is factory set at 140 psig. Some original equipment manufacturer burner applications 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 • Verify 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 • The flue gas venting system must be in good condition and must comply with all applicable codes. Figure 1.

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 fl oor. Verify that the chamber dimensions are at least as large as the minimum values given in Figure 2. 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 – CF500 1.75 to 5.50 GPH CF800 Tube A — 3.00 to 7.00 GPH Tube B — 5.00 to 8.00 GPH Maximum firing capacity depends on the fi rebox pressure.
