A boiler fired with Class C2 Oil should only require attention once a year.
8:1.1 General Inspection
With the Boiler operating, inspect for signs of unsatisfactory operation, i.e. leakage of combustion products,
leakage of oil, or unusual noises from the pump or motor.
Check the commissioning list if it is your first attendance to the appliance. Is there a reason why the Boiler
might fail after you leave?
It is useful to measure the combustion data, i.e. C02; Smoke No; the flue gas temperature and a check on the
oil pressure prior to carrying out any maintenance work.
8:1.2 Maintenance Procedure
Switch off electrical supply at the MAINS ISOLATING SWITCH.
OIL TANK
De-sludge oil tank (if necessary), and draw of any accumulated water. Check the correct grade of oil is being

Inspect the ignition electrodes for crazing in the porcelain. Replace if here are signs of deterioration.
A dirty fan impeller can impair the performance of a burner, inspect and clean if necessary.
Inspect photocell, if badly discoloured, change it.
Inspect the flexible oil hose for leaks or discoloration. Uses only replacement flexible oil hoses that are
detailed in the spare parts section of this manual.
