Oil Burner Maintenance
The following preventative maintenance items should be
performed annually, preferably prior to the heating season.
A. Oil Burner Motor
Add 2--3 drops of non--detergent electric motor oil to each oil cup
located at front and rear of motor. Excessive oiling will shorten
the life expectancy of motor.
B. Fuel Filter
This should be replaced so as to prevent contaminated fuel from
reaching the nozzle. A partially blocked fuel filter can cause
premature failure of fuel pump unit.
C. Fuel Pump Unit
Replace pump screen and clean pump unit to maintain reliable
fuel delivery to nozzle.
D. Ignition Electrods
Clean and adjust as per manufacturer’s recommendations so as to
maintain reliable ignition of oil.
E. Nozzle
Replace so as to maintain safe and reliable combustion efficiency.
Always replace with the exact nozzle as required in Table 7.
These must be kept clean and free of dirt, lint, and oil so as to
maintain proper amount of air the fuel requires to burn.
NOTE
: If any component parts must be replaced, always use
parts recommended by burner manufacturer.
F. Fan and Blower Housing
Check burner blower wheel for dirt, grease and grime. Clean as
necessary. Check motor is attached to burner housing and wheel
is attached tightly to motor shaft. Check pump coupling for wear
and damage.
