Below is some emergency advice on how to isolate your fuel tank, restart your boiler.
Only carry out if you feel comfortable in doing so, otherwise ring me.
My Boiler will not start
If you can, access the burner, usually behind a casing door. Is there a red/orange light on at the control box? If there is then the burner has shut down safely because something is wrong. First check to see if you have oil in your fuel tank and that the outlet valve is turned ON. Return to your boiler and press/release the illuminated lock-out button, the burner should start and run through its start-up procedure. Sometimes you can get a random lock-out that happens for no reason, so pressing the lock-out button may restart the burner and it may run fine again. If your burner goes to lock-out again after the second attempt, then this is the time to call me.
I have run out of oil, had a refill and cannot now restart my boiler
If you have run out of oil and have had a refill do not try and restart your boiler until a good 30 minutes after delivery, this time will allow the sediment that the refill stirred up to settle and not get drawn through to your filters if it has already not done so. After this time you can try and press/release the lock-out button on the burner control box to restart, you can try this a MAXIMUM of three times, further “trying” may damage your ignition transformer, it is designed to operate ONCE on start up to ignite the burner, continuous operation will overheat it and could damage it. After a run-out there is a good chance that you will not be able to restart your boiler even after the three “tries” as air will have been drawn into your fuel line, also there is a chance that debris has blocked/restricted your fuel filters. This is the time to call me to restart your boiler.
If you have an Oil Leak
If you have an oil leak in or around your boiler or between the boiler/fuel tank and it is more than a weep/drip that you can catch in a container until an engineer can come out to you, then it is best that you turn off the supply from your fuel tank. Remember also to turn off your boiler, either via the programmer or at the spur.
Types of isolation valves
If you have this type of valve on your fuel tank, then to turn OFF, turn the wheel CLOCKWISE until the wheel becomes loose, you may have to PULL the wheel when loose to help to stop the supply. This valve/filter should be serviced when your boiler is serviced so that it is able to be shut off when required. Also there is a lead insert in the wheel that is designed to shut off the fuel supply in the event of a fire, another reason for it to be serviced.
If you have this type of valve on your fuel tank, then to turn OFF, turn the wheel CLOCKWISE until it becomes tight. This type of valve must also be checked for free operation when your boiler is serviced.
