This burner is shipped with the oil pump set to
operate on a single line system. To operate on a
two-line system the bypass plug must be
installed.
WARNING : DO NOT operate a single line system
with the by-pass plug installed. Operating a
single line system with the by-pass plug installed
will result in damage to the pump shaft seal.
Note:
Pump pressure was factory pre-set but must
be checked at time of burner start-up. A
pressure gauge is attached to the
PRESSURE/
BLEEDER PORT
(7) for pressure readings.
Two
PIPE CONNECTORS
(4) are supplied
with the burner for connection to either a single
or two-line system. Also supplied are two
ADAPTORS
(3), two female ¼” NPT to adapt
oil lines to burner pipe connectors. All pump
port threads are
British Parallel Thread
design.
Direct connection of NPT threads to the pump
will damage
the pump body.
Riello manometers and vacuum gauges
DO
NOT
require any adapters, and can be safely
connected to the pump ports. An NPT x metric
adapter
must
be used when connecting other
gauge models.
