Connect fuel line(s)

• Install the oil lines using the following
guidelines. Failure to comply could lead
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

does not exceed the fuel unit manufacturer's
recommendation.
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,
pass plug must be left in the fuel unit
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.

for the fuel unit gearset capacity - the rate at which fuel is
recirculated when connected to a two-pipe system. Size
