Note: Pump pressure must be set at time of burner start-up. A pressure gauge is

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 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 adaptors, and can be safely
connected to the pump ports. An NPT (metric) adapter must be used when connecting
other gauge models.
