RWB 6104 BAFG R02

  The burner may be equipped with a single-stage 

fuel unit for these installations. Connect the fuel 
supply to the burner with a single supply line if you 
want a one-pipe system (making sure the bypass 
plug is NOT installed in the fuel unit.) Manual bleed-
ing of the fuel unit is required on initial start-up. If 
connecting a two-pipe fuel supply, install the fuel 
unit bypass plug.

Turn off power to burner before proceeding.
Disconnect oil connector tube from nozzle line.
Loosen the two screws securing igniter retain-
ing clips and rotate both clips to release igniter 
baseplate. Then tilt igniter back on its hinge.
Remove splined nut.
“F” head air tube. - Remove nozzle line assem-
bly from burner, being careful not to damage the 
electrodes or insulators while handling. To ease 
removal of long assemblies (over 9 inches), ro-
tate assembly 180° from installed position after 
pulling partially out of tube.
“L1”, “L2”, and “V1” head air tubes. -   S l i d e 
nozzle  line  assembly  forward  (further  into  air 
tube) so the head clears the venturi opening. 
Then rotate the nozzle line assembly 90° so the 
nozzle line end points up. Pull the nozzle line 
assembly toward you and remove assembly 
from burner.
To replace the nozzle assembly, reverse the 
above steps.

Mount burner on appliance

Bolt the burner to the appliance using the fac-
tory-mounted fl ange or an adjustable fl ange.

When using the Beckett universal adjustable 
fl ange, mount the air tube at a 2° downward 
pitch unless otherwise specifi ed by the appli-
ance manufacturer.
Verify that the air tube installed on the burner 
provides the correct insertion depth. See Fig-
ure 6.
The end of the air tube should normally be ¼” 
back from the inside wall of the combustion 
chamber. Never allow the leading edge of the 
head assembly to extend into the chamber, un-

WARNING

less otherwise specifi ed by the heating appli-
ance manufacturer. Carefully measure the in-
sertion depth when using an adjustable fl ange. 
Verify the insertion depth when using a welded 
fl ange.

  Carefully follow the fuel unit manufacturer’s litera-

ture and the latest edition of NFPA 31 for oil supply 
system specifi cations.

If space between burner 

air tube and opening 
exceeds 1/2 inch, pack 
burner opening with ce-
ramic fiber refractory.

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.
