To the Owner:

 

Thank you for purchasing a Beckett NX burner 

for use with your heating appliance.  Please pay atten-
tion to the Safety Warnings contained within this in-
struction manual.  Keep this manual for your records 
and provide it to your quali

fi

 ed service agency for use 

in professionally setting up and maintaining your NX 
burner.

  Your NX burner will provide years of ef

fi

 cient operation 

if it is professionally installed and maintained by a quali-

fi

 ed service technician.  If at any time the burner does 

not appear to be operating properly, 

immediately con-

tact your qualifi ed service agency

 for consultation.

 

We recommend annual inspection/service of your 
oil heating system by a qualifi ed service agency. 

 

Daily 

– Check the room in which your burner/appliance 

is installed.  Make sure:

 Air ventilation openings are clean and unobstructed
 Nothing is blocking burner inlet air openings
 No combustible materials are stored near the heating 
appliance
 There are no signs of oil or water leaking around the 
burner or appliance

 

Weekly  

Check your oil tank level.  Always keep your oil tank 
full, especially during the summer, in order to prevent 
condensation of moisture on the inside surface of the 
tank.



Contact a professional, qualified service agency for the 
installation, adjustment and service of your oil heating 
system.  This work requires technical training, trade 
experience and the proper use of special combustion test 
instruments.

instructions:
