  Install two high quality oil duty rated shutoff valves 

in accessible locations on the oil supply line. Locate 
one close to the tank and the other close to the 
burner, upstream of the fi lter.

  Also install a generous capacity fi lter, rated for 50 

microns or less, inside the building between the 
fuel tank shutoff valve and the burner. Locate both 
the fi lter and the valve close to the burner for ease 
of servicing. 

  When installing an NX outside air adapter (Beck-

ett Part Number 5199OU), refer to the instruction 
sheet supplied with the adapter. This kit allows 
combustion air to be piped directly to the burner. 
The NX outside air adapter  kit may also be used 
for chimney vent applications that require outside 
combustion air.

  Route the fuel line through the opening in the bottom 

of the burner cover. Continuous lengths of heavy 
wall copper tubing are recommended. Always use 
fl are fi ttings. Never use compression fi ttings.

 Always install fi ttings in accessible locations. To 

avoid vibration noise, fuel lines should not run 
against the appliance or ceiling joists.

The outside air adapter must be installed by strictly
following the kit installation instructions. Do NOT attempt to
install outside air piping without using the outside air
adapter and instructions provided. Abundant fresh air is
required for proper combustion.

!

Never use Teflon tape on any fuel fitting. Tape
fragments can lodge in fuel line components and fuel
unit, damaging the equipment and preventing proper
operation.

S111

!

  For protection in the event of fi re, some states 

require the shutoff valves to be a fusible-handle 
design. R.W. Beckett Corporation recommends 
this design as good industry practice for all in-
stallations.
