refer to Figure 9.
This burner is shipped with the oil pump set
to operate on a single line system. To operate
on a two-line system the bypass 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 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.
h. Replace Burner Cover and Tighten Burner
Cover Screws.

INSTALL WATER BOILER TRIM AND CONTROLS,
(see Figures 1A and 1B)
1. Install return piping supplied with boiler. Apply
Teflon or Sealant to all joints prior to assembly.
Thread 1½" NPT x 5" Lg. return nipple into 1½"
NPT tapping located in lower left corner of front
section. Thread 1½" x ¾" x 1½" NPT tee onto
5" nipple. Thread ¾" drain valve into ¾" NPT
connection on tee. Tighten all joints with wrench
Figure 9: Riello Pump Connections and Port Identification
until water tight and 1½" NPT return connection on
tee is facing away from boiler horizontally to allow
for proper burner swing door clearance, see Figures
1A, 1B, 11A and 11B.
Note:
Vertical piping will prevent door from opening
fully for service and cleaning of boiler.
2. Thread relief valve onto factory installed ¾" NPT
x 7¼" nipple located in left rear corner on top
of boiler as shown in Figures 1A and 1B. Valve
spindle must be in vertical position. Tighten with
wrench. Pipe discharge as shown in Figures 11A
and 11B. Installation of the relief valve must be
consistent with ANSI/ASME Boiler and Pressure
Vessel Code, Section IV.
3. Connect Field Wiring
Connect the field wiring to the Warm or Cold Start
Intelligent Oil Boiler Control (Boiler Control).
Make the wiring connections as shown in Figures 20
and 21.
a. On water boilers without rear tankless heater,
connect the field wiring from the circulator to
the Cold Start Boiler Control and from the Cold
Start Boiler Control to the Burner Oil Primary
Control. Make the wiring connections as shown
on Figure 20.
