24 Vdc SDC Burner Manual
A. Connect Fuel Lines
For oil supply system specifi cations for tanks not mounted 
on machines, carefully follow the pump manufacturer’s 
literature and the latest edition of the National Fire 
Protection Association (NFPA) 31 standard.  
B. Fuel Supply Level with or Above Burner
Section: Fuel Supply
Do Not Install Bypass Plug 
with 1-Pipe System
Failure to comply could cause Immediate pump seal 
failure, pressurized oil leakage and the potential for a 
fi re and injury hazard. 
The burner is shipped without the bypass plug installed.
Install the bypass plug in two-pipe oil supply systems 
ONLY.

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 the return line. (NFPA 31, 
Chapter 8.)
Gravity Feed Systems: Always install an anti-siphon 
valve in the oil supply line or a solenoid valve (RWB 
Part # 22246U) in the pump/nozzle discharge tubing 
to provide backup oil fl ow cut-off protection.

Do Not Use Tefl on Tape
Damage to the pump could cause impaired burner 
operation, oil leakage and appliance soot-up.
Never use Tefl on tape on fuel oil fi ttings. 
Tape fragments can lodge in fuel line components 
and fuel unit, damaging the equipment and preventing 
proper operation.
Use oil-resistant pipe sealant compounds.

The burner may be equipped with a single stage pump. 
If a one-pipe system is installed, verify a bypass plug is 
not installed in the pump, then connect the fuel supply 
to the burner with a single supply line Note that manual 
bleeding of the pump is required on initial start-up or 
when the equipment runs out of fuel. When connecting 
a two-pipe fuel system, install the pump bypass plug.
C. Fuel Supply Below Level of Burner
When the fuel supply is more than eight feet below 
the level of the burner, a two-pipe fuel supply system 
is required. Depending on the fuel line diameter and 
the horizontal and vertical length, the installation 
may also require a two-stage pump. Consult the 
fuel unit manufacturer’s literature for lift and vacuum 
capability. 
D. Fuel Line Replacement (Remote Tank Only)
When replacing fuel lines, continuous lengths of heavy 
wall copper tubing is recommended. To ensure a tight 
seal, always use fl are fi ttings. Never use compression 
fi ttings. Always install fi ttings in an accessible location. 
To avoid vibration noise,  fuel lines should not run 
against the appliance or the ceiling joists.
E.  Fuel Line Valve and Filter
Shutoff valves should be located in the oil supply line. 
Do not install valves in the return line.
Fuel Supply
Pumps with automatic bypass do 
not require a bypass plug. Verify 
by referring to the pump manufacturer’s instructions.
