  The burner is supplied with either a one-stage 
pump or a two-stage pump based on the oil supply 
system requirements.  Consult the instructions pro-
vided with the pump for installation specifi cations.
Connect Fuel Lines
Start the Burner and Set Combustion
Do not attempt to start the burner when excess oil 
has accumulated in the appliance, the appliance 
is full of vapor, or when the combustion chamber 
is very hot.  
Do not attempt to re-establish fl ame with the 
burner running if the fl ame becomes extinguished 
during start-up, venting, or adjustment.
Vapor-Filled Appliance: Allow the unit to cool off 
and all vapors to dissipate before attempting an-
other start. 
Oil-Flooded Appliance: Shut off the electrical 
power and the oil supply to the burner and then 
clear all accumulated oil before continuing.
If the condition still appears unsafe, contact the 
Fire Department. Carefully follow their directions. 
Keep a fi re extinguisher nearby and ready for 
use. 
Failure to follow these instructions 
could lead to equipment malfunc-
tion and result in heavy smoke 
emission, soot-up, hot gas puff-
back, fi re and asphyxiation hazards.
Explosion and Fire Hazard 
WARNING
!
  The R7184 primary control with valve-on delay and 
burner motor-off delay, shown in Figure 4, requires 
a constant 120 volt AC power source supplied to 
the black wire on the control. (Refer to the appli-
ance manufacturer’s instructions. The red wire 
goes to the appliance limit circuit. Please note that 
other control manufacturers may use different wire 
colors for power and limit connections.
Start the Burner and Set Combustion
 Startup burner
The oil supply inlet pressure to the burner cannot 
exceed 3 psig
.  
Insure that a pressure limiting device is installed 
in accordance with the latest edition of NFPA 31. 
Gravity Feed Systems: Always install an anit-
siphon valve in the oil supply line or a solenoid 
valve (RWB Part # 2182602U) in the pump/noz-
zle discharge tubing to provide backup oil fl ow 
cut-off protection. 
Damage to the fi lter or pump seals could cause 
oil leakage and a fi re hazard.
Oil Supply Pressure 
Control Required
!
!
CAUTION
The burner is shipped without the by-pass plug in-
stalled.
Install the by-pass plug in two-pipe oil supply systems 
ONLY. 
Failure to comply could cause immediate pump 
seal failure, pressurized oil leakage and the po-
tential for a fi re and injury hazard. 
Do Not Install By-pass Plug 
with 1-Pipe System
WARNING
!
  When installing a one-pipe system, connect the 
inlet line to the pump inlet.  The fuel pump may be 
installed with gravity feed or lift.  The maximum al-
lowable lift for a single pipe installation is 8 ft.  
  When installing a two-pipe system, remove the 
1/16” pipe by-pass plug from plastic bag attached 
to fuel unit.  Remove 1/4” plug from return port.  
Insert and tighten the by-pass plug.  Attach return 
and inlet lines.  The return line should terminate ap-
proximately 3 to 4 inches above supply line inlet.  
Failure to do this may introduce air into the system 
and could result in loss of prime.
Wiring Connections Diagram
  Refer to the appliance manufacturer’s wiring dia-
gram prior to connecting the burner wiring. All wir-
ing must be in accordance with the latest revision of 
National Electric Code NFPA 70 and all local codes 
and regulations.
    
Open the shutoff valves in the oil supply line to 
the burner.
Open the air dial. This is an initial air setting for 
the pump bleeding procedure only. Additional ad-
justments must be made with instruments.
Set the thermostat substantially above room tem-
perature.
Close the line voltage switch to start the burner. 
If the burner does not start immediately you may 
have to reset the safety switch of the burner pri-
mary control.
Bleed air from the fuel unit as soon as burner mo-
tor starts rotating. To bleed the fuel unit, attach 
a clear plastic hose over the vent fi tting. Loosen 
the fi tting and catch the oil in an empty container. 
Tighten the fi tting when all air has been purged 
from the oil supply system.
