INSTRUCTIONS FOR TROUBLE - SHOOTING AND REPAIRING OPERATING
PROBLEMS WITH HEAVY OIL BURNERS
PROBLEM
Nois burner pump
Fuel oil heats up too slowly, or
doesn't heat up at all.
Burner does not start when the
minimum preheating temperatu-
re for the fuel oil is reached.
Burner does not start
Poor fl ame, with sparks
POSSIBLE CAUSE
1) Fuel oil in the tank too viscous
2) Pipeline diameters too small
3) Air entering into the pipelines
4) Dirty fi lter
5) Too great a distance between tank and
burner, or meny accidental load lossen
(curves, elbows, pinches, etc.)
6) Worn hoses
7) Fuel oil too viscous in some part of the
intake pipeline
1) Mains voltage too low
2) One or more heating coils burned out
3) Defective or mistaken electrical con-
nections
4) Total heating coil power lower than
nozzle capacity requirements
1) Thermostats (boiler or room) or pres-
sure switches are open
2) Short - circuit photoresistance
1) No current, either main switch is open,
or meter circuit breaker open or mains
failure
2) Thermostat line is not made accor-
ding to the diagram, or a thermostat
is open
3) Breakdown inside the appliance
1) Fuel oil too cold
2) Atomozing pressure too low
3) Excess combustion - supporting air
4) Dirty or worn nozzle
5) Water in the fuel

REMEDY
1) Preheat in the tank or replace with a more
fl uid oil
2) Replace pipelines, in accordance with instal-
lation instructions
3) Find and eliminate any infi ltrations
4) Dismantle and clean
5) Straighten out the path travelled by the intake
pipeline, reducing the distance
6) Replace hoses
7) Properly insulate the pipeline
1) Speak with the electric Company
2) Replace
3) Check
4) Decrease fl ow rate, insofar as is possible
with the plant's heating requirements
1) Raise their settings, or wait until pres-
sure or temperaturevalues naturally
decrease to close them
2) Replace
1) Close switches or wait until power
returns
2) Check connections and thermostats
3) Replace
1) Increase temperature using the prehea-
ter control thermostat
2) Reset at proper value
3) Reduce combustion - supporting air
4) Clean or replace
5) Drain water from the preheating tank
and the mesh fi lter through the drain
plugs. Drain water, if necessary, from the
fuel tank as well, using a suitable pump
(never use the burner pump to do this)
