Annual Professional
Service Required
Annual service — by qualifi ed service techni-
cian
Have the burner inspected, tested and started at least annually
by a qualifi ed service technician. This annual test/inspection
should include at least the following:
Replace the oil supply line fi lter. The line fi lter cartridge
must be replaced to avoid contamination of the fuel unit
and nozzle.
Inspect the oil supply system. All fi ttings should be leak-
tight. The supply lines should be free of water, sludge and
other restrictions.
Remove and clean the pump strainer if applicable.
Replace the nozzle with the exact brand, pattern, gph, fl ow
rate and spray angle.
Clean and inspect the electrodes for damage, replacing
any that are cracked or chipped.
Check electrode tip settings. Replace electrodes if tips are
rounded.
Inspect the igniter spring contacts.
Clean the cad cell lens surface, if necessary.
Inspect all gaskets. Replace any that are damaged or would
fail to seal adequately.
Inspect the combustion head and air tube. Remove any
carbon or foreign matter. Replace all damaged units with
exact parts.
Clean the blower wheel, air inlet, air guide, burner hous-
ing and static plate of any lint or foreign material.
If motor is not permanently lubricated, oil motor with a
few drops of SAE 20 nondetergent oil at each oil hole.
DO NOT over oil motor. Excessive oiling can cause mo-
tor failure.
Check motor current. The amp draw should not exceed the
nameplate rating.
Check all wiring for secure connections or insulation
breaks.
Check the pump pressure and cutoff function.
Check primary control safety lockout timing.
Check ignition system for proper operation.
Inspect the vent system and chimney for soot accumula-
tion or other restriction.
Clean the appliance thoroughly according to the manufac-
turer’s recommendations.
Check the burner performance. Refer to the section “Set
combustion with test instruments”.
It is good practice to make a record of the service per-
formed and the combustion test results.
