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.
