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
(6) 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 (metric) adapter
must
be used when connecting other gauge models.
SINGLE LINE (GRAVITY FEED SYSTEM)
A) The burner is shipped configured for use in single line applications. No changes to the oil pump are required for use
in single line applications.
NOTE:
If the
pump cover
(1) is removed for any reason, be sure the O-ring (2), is properly seated in the pump cover
(1) before re-attaching the pump cover to the pump housing.
B) Connect the pipe connector to the SUPPLY PORT(5) of the pump. Attach the NPT adapter to the pipe connector.
Attach the required piping to this pipe adapter. Be sure that the plug in the RETURN PORT (7) is tightened securely.
