Beckett CF 2300A Connect fuel lines, Fuel unit by-pass plug, One-pipe oil system by-pass loop

Instruction Manual – Model CF2300A Oil Burner

Connect fuel line(s)

• Install the oil lines using the following

guidelines. Failure to comply could lead

Figure 8a – One-pipe oil flow, low fire,“H” pump

to equipment damage and present a risk of

severe personal injury, death or substan-

tial property damage due to leakage of oil

and potential fire hazard.

• Use only flare fittings at joints and con-

nections. Never use compression fittings.

• Install fittings only in accessible locations

to assure any leak will be detected.

• Where joint sealing is needed, use only

pipe dope. Never use Teflon tape. Tape

strands can break free and damage the fuel

unit.

• Never use a one-pipe oil system with a lift

in excess of 8 feet with a B fuel unit, or 2

feet with an H fuel unit. On two-pipe oil

systems, verify that the suction line vacuum

❏ Fuel unit by-pass plug

•The CF2300A burner is shipped with a by-pass plug in- stalled in the fuel unit. For low/high operation, the by- pass plug must be left in the fuel unit, regardless of the fuel system used (one-pipe with by-pass loop or two- pipe). Do not remove the by-pass plug.

Do not operate the burner unless a return line or by-pass loop is installed. Failure to follow this guideline will cause damage to the fuel unit seals and consequent fuel leakage. This could result in severe personal injury, death

or substantial property damage.

❏One-pipe oil system by-pass loop

•Refer to Figure 8 (item m). Note the addition of a field- installed 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. Figures 8a and 8b are for type H fuel units. Figure 8c is for a type B fuel unit.

•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 flow rate.
