Connect fuel line(s)

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 B fuel unit, or 2 feet with H fuel unit. On two-pipe oil systems, verify that the suction line vacuum does not exceed the fuel unit manufacturer’s recommendation.

The fuel unit is shipped without the by-pass plug installed for CF1400 ON/OFF burners. You must install this plug on two-pipe systems. DO NOT install the by-pass plug in the fuel unit if connected to a one-pipe oil system. Failure to comply could cause fuel unit seal failure, oil leakage and potential fire and injury hazard.

Fuel unit by-pass plug

The CF1400 burner is shipped without the by-pass plug installed in the fuel unit.

The by-pass plug must not be installed in the fuel unit for one-pipe oil systems.

You must install the by-pass plug if using on a two-pipe oil system.

Oil supply/return lines

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
