the service performed and the combustion test results.
q Replace the oil supply line filter. The line filter car-
tridge must be replaced to avoid contamination of
the fuel pump and nozzle.
q Inspect the oil supply system. All fittings should be
tight and leak-free. The supply lines should be free
of water, sludge and other restrictions.
q Remove and clean the pump strainer if applicable.
q Replace the used nozzle with a new nozzle that
conforms to the appliance manufacturer's specifi-
cations.

if tips are rounded.

or fail to seal adequately.

or foreign material.

any accumulated soot or oil stains from the sight
glass viewing window.

tion breaks.
