OIL LINE CONNECTIONS
This burner is shipped with the oil pump set to operate on a single line system.
To operate on a two line system the by-pass 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 must be set at time of burner start-up. A pressure gauge is attached to the PRESSURE PORT (8)
for pressure readings. Two PIPE CONNECTORS (5) are supplied with the burner for connection to either a single or a
two-pipe system. Also supplied are two ADAPTORS (3), two female 1/4" NPT, to adapt oil lines to burner pipe connec-
tors. All pump port threads are British Parallel Thread design. Direct connection of NPT threads to the pump will dam-
age the pump body.
Riello manometers and vacuum gauges do not require any adaptors, and can be safely connected to the pump ports.
An NPT (metric) adapter must be used when connecting other gauge models.
