leakage of oil, or unusual noises from the pump or motor.
Check the commissioning list if it is your 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.CO2, Smoke No. and flue gas temperature, and a check on
the oil pressure, prior to carrying out maintenance work.
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 used.
FILTERS
Inspect and clean all oil filters. Change paper elements for new.
BOILER
This boiler is serviced from the front.
Remove flue inspection cover, and baffles, and clean all heat transfer surfaces and baffles. Replace any
damaged or unserviceable parts with manufacturers proprietary parts.
FINAL CHECKS
Check lockout function, either remove photocell and cover it, or remove solenoid coil, to simulate flame
failure. Reinstate components and press lockout reset button.
Check that the control thermostat is operating when the set temperature is reached.
Check the operation of the limit thermostat if possible.
Reset Limit Thermostat once appliance temperature has dropped sufficiently.
Complete a maintenance report and give the customer
BURNERS
Turn off the oil cock and disconnect the flexible oil hose from the oil cock.
Remove burner and clean thoroughly, the burner draught tube, the electrodes and generally the head
assembly. CHANGE the nozzle for one with the specified make, oil rate, spray pattern and angle.
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. Use only replacement flexible oil hoses that are detailed
in the spare parts section of this manual.
