10. Oil burners maintenance instructions 

General information

Keep the boiler room clean. Ensure that the boiler 

room has permanent fresh air intake. Switch off before 

dismantling the oil burner. 

At hinged mounting, make sure that an automatic safety 

switch is fitted, so that the burner cannot start when 

theswing door is open. 

Don´t use the oil fired boiler to burn paper or 

rubbish,unless the boiler is especially fitted with a hinged 

door tomake this possible. 

Don´t fill tank while burner is working.

Starting precautions

Make sure that the oil tank is not empty 

Make sure that the valves on oil and water supply pipes 

areopen. 

Make sure that the boiler flue damper is open. 

Make sure that the boiler thermostat is set at the correct 

temperature. 

Switch on the current. Most relay systems have a 

delayed action so that the burner will not start for 

perhaps 20 seconds. 

With heavy oil the delay will be longer as the burner 

will notstart until the oil in the preheater reaches the 

requiredtemperature.

If the burner will not start

Press the reset button on the relay. Check that the 

thermostats are correctly adjusted. 

Don´t forget the room thermostat, check that any 

fusesare intact and main switch is on. 

If the burner starts but does not ignite

Make an attempt to start the burner. 

Never make close repeated start attempts. 

Don´t restart the burner until the boiler is free from oil 

gases. 

If the burner still does not ignite send for the service 

engineer.

When switching off during summer

Always use the main switch to cut out the burner even 

when adjusting the burner or cutting off the heating for 

ashort time. For longer periods of shut down, close all 

valves and the oil supply stop-cock. 

Clean the filter and nozzle by washing in petrol or 

paraffin. 

Make sure the filter medium is not damaged or defective. 

Protect electrical gear from damp.

Warning

Never stand too near or put your face to the inspection 

or fire door, when the burner is about to start. 

Never use a naked flame to ignite oil if the electrical 

ignition fails. 

Always wait for about 10 minutes for the unburnt gases 

to disperse before restarting the oil burner if it has failed 

to ignite previously.
