PUMP CONNECTIONS AND PORT IDENTIFICA-
TION
This burner is shipped with the oil pump set to oper-
ate on a
single line system. To operate on a two-line
system the by-pass plug must be installed.

CAUTION
!
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 PRES-
SURE PORT (8) 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.
NOTE: Direct connection of NPT threads to the
pump will damage the pump body.
