Do not remove the by-pass plug. Install Oil Supply ToSpecifications Failure to properly install the oilsupply system could cause oil leakage, equipment malfunction, puff-back of hot gases, heavy smoke, asphyxiation, explosion and fire • Carefully install the oil supply lines, fi ttings and components using the guidelines provided in this section. • The oil supply must comply with the latest edition of NFPA 31 (Canada CSA B139) and all applicable codes. • Do NOT install valves in the return line. • If the oil supply inlet pressure to the pump exceeds 3 psig or for gravity feed systems, install an oil safety or pressure reducing valve (Webster OSV, Suntec PRV or equivalent). • One-pipe oil system by-pass loop Refer to Figure 9 (item m). Note the addition of a fieldinstalled by-pass loop (use 3/8” copper tubing) from the fuel unit Return port to the Inlet port. This line is required for low/high operation. It simulates the flow of a two- pipe system at the fuel unit. Factory-Installed PumpBypass Plug Failure to follow these guidelines will causethe fuel pump seals to rupture and result in oilleakage, burner malfunction and potential fire and injury hazards. • Models CF1400 and CF2300 are shipped with the pump bypass plug installed. • Do not remove the bypass plug from the pump. It is required for step-firing (Lo/Hi) operation. • Do not operate the burner unless a return line or bypass loop is installed or the pump seal will rupture. • Carefully comply with the following instructions provided in this section of the manual. • Install the oil tank and oil lines in accordance with all applicable codes. • Size the oil supply and return lines using the guidelines given in the fuel unit literature included in the literature envelope. Oil line flow rate will equal the burner rate for one-pipe systems. For two-pipe systems, refer to Table 3 for the fuel unit gearset capacity - the rate at which fuel is recirculated when connected to a two-pipe system. Size two-pipe oil lines based on this fl ow rate. • Use continuous lengths of heavy-wall copper tubing, routed under the floor where possible. Do not attach fuel lines to the appliance or to floor joists if possible. This reduces vibration and noise transmission problems. • Install an oil filter sized to handle the fuel unit gearset flow capacity (Table 3) for two-pipe systems. However, size the filter for the firing rate for one- pipe systems. Locate the filter immediately adjacent to the burner fuel unit. • Install two high-quality shutoff valves in accessible locations on the oil supply line. Locate one valve close to the tank. Locate the other valve close to the burner, upstream of the fuel fi lter. • Burner fuel flow One-pipe systems – See Figure 9 for the fuel fl ow paths for high-fire and low-fire operation. The low-fi re by-pass regulation is done internally for type B fuel units. Oil supply connects to one of the fuel unit Inlet ports. Two-pipe systems – See Figure 10 for the fuel flow paths for high-fire and low-fire operation. The low-fire by-pass regulation is done internally for type B fuel units. Oil supply connects to one of the fuel unit Inlet ports. Oil return connects to the fuel unit Return port. Low-fire/high-fi re operation – The fuel unit nozzle port pressure is factory set at 300 psig. • At high fire, full pressure (300 psig) is applied at the oil nozzle, causing full input. • At low fire, the by-passing is done inside the fuel unit when the by-pass valve operates. • This by-passing of oil reduces the oil pressure at the nozzle (to between 125 psig and 175 psig), reducing the input.

(This may also be required to aid proper control system operation) • Perform all wiring in compliance with the National Electric Code ANSI/NFPA 70 (Canada CSA C22.1). Install the burner and all wiring in accordance with the National Electrical Code and all applicable local codes or requirements.
