Combustion Air Supply
Fuel Supply
Figure 1 – Typical Nameplate
The burner requires combustion air and ventilation air 
for reliable operation. Assure that the building and/or 
combustion air openings comply with National Fire 
Protection Standard for Oil-Burning Equipment, NFPA 31. 
For appliance/burner units in confi ned spaces, the room 
must have an air opening near the top of the room plus 
one near the fl oor, each with a free area at least one 
square inch per 1,000 Btu/hr input of all fuel burning 
equipment in the room. 
For other conditions, refer to the latest edition of NFPA 31 
(CSA B1139-M91 in Canada).
If there is a risk of the space being under negative 
pressure or of exhaust fans or other devices depleting 
available air for combustion and ventilation, the appliance/
burner should be installed in an isolated room provided 
with outside combustion air.
Clearances
With the burner installed in the appliance, there must be 
adequate space in front of and on the sides of the burner 
to allow access and operation. Verify that the clearance 
dimensions comply with all local codes and with the 
appliance manufacturer’s recommendations.
The fuel supply piping and tank must provide #1 or #2 
fuel oil at pressure or vacuum conditions suitable for 
the fuel unit (oil pump) on the burner. Refer to fuel unit 
literature in the literature envelope in the burner carton to 
verify allowable suction pressure.
If fuel supply is level with or higher than fuel unit —
When the fuel unit is not required to lift the oil, the 
installation is usually suitable for either a one-pipe or 
two-pipe oil system. The oil pressure at the inlet of 
the fuel unit must not exceed 3 psig.
The fuel unit is shipped with the by-pass plug 
installed. Leave the by-pass plug installed for all 
low/high fi ring burners, regardless whether one-
pipe (with by-pass loop) or two-pipe. See Figure 
9
 for installation of the by-pass loop required for 
one-pipe fuel supply installations. See Figure 10 for 
connections to the fuel unit for two-pipe fuel supply 
installations.
When fuel supply is below the burner fuel unit —
Use a two-pipe oil system when the fuel unit must lift 
the oil more than 8 feet. The return line provided by the 
two-pipe system is needed to minimize the effects of air-
related problems during operation.
Adequate Combustion and 
Ventilation Air Supply Required
Failure to provide adequate air supply could 
seriously affect the burner performance and result in 
damage to the equipment, asphyxiation, explosion or 
fi re hazards.
The burner cannot properly burn the fuel if it is not 
supplied with a reliable combustion air source.
Follow the guidelines in the latest editions of the 
NFPA 31 and CSA-B139 regarding providing 
adequate air for combustion and ventilation.

Oil Supply Pressure 
Control Required
Damage to the fi lter or pump seals could cause oil 
leakage and a fi re hazard.
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. 
Do not install valves in return line.
Gravity Feed Systems: Always install an anti-siphon 
valve in the oil supply line or a solenoid valve (RWB 
Part # 21789) in the pump/nozzle discharge tubing 
to provide backup oil fl ow cut-off protection.
