I have just had oil delivered to an empty tank and the central heating won't work. I opened the back of the boiler to press the red reset button and it started but turned off after about 10 seconds. I tried this several times with the same result. How can I get the boiler to function properly?Can you help with an oil-fired central heating problem?
ARGHHH. Do NOT disconnect any lines as the other yahoos suggest.
If your boiler is in the basement your anti-siphon device would prevent that from bleeding out the air anyway.
Gizmoe is right, I do not think I have seen him steer anybody wrong.
The bleeder valve on the burner pump is used to bleed out the air.
But you should never run your tank to empty. Nine times out of ten that sucks crud or water off the bottom of the tank and plugs up the filter and nozzle. Then when they fill it also stirs the junk up and you should let it settle for a day before trying to start it after filling an empty tank.
Oil floats on water so the water goes to the bottom. The feed line is not completely down on the bottom to prevent picking that up. But a single drop of water will block the nozzle as it won't pass through the oil soaked ceramic filter on it.
That is also why you should always keep your tank full. The more air space the more condensation you get and the more times you will need a service call or your tank cleaned.
I have little doubt you need a service call. And do not push the reset button more than a couple times before calling for service because if you have an ignition problem and not an oil problem, you load the chamber full of unburnt fuel and if it fires up it will fill the house with smoke.
Sorry, but I have little doubt you need a tuneup service call for at least a filter and nozzle.
And be sure to tell the service guy you pushed the reset several times so if it has unburnt fuel in the chamber he can soak it up or burn it off slowly.
Good Luck.Can you help with an oil-fired central heating problem?
you have an airbound situation at the fuel pump. whether you have a buried tank or an above gound tank the procedures are similar. on the oil burner there is the oil pipe coming from the oil tank. now where it connects to the oil burner that part is called the oil pump. looking at the pump from the face side there is a bleeder valve. most pumps have this device at the 4 oclock position. it looks like a bleeder on car brakes. it is usually a3/8 size wrench. put a little container under it then hit the reset button while opening this bleeder. air will stsrt gushing out. once you get a good flow of oil shut it and the burner will fire up. you may have to repeat this procedure a second time.
The fuel pump will need to be bled. The pump is located on the burner where the fuel line connects.
A port resembling a brake bleeding port needs to be opened while the burner is operating until a steady stream of fuel is observed.
Use a small piece of tubing on the port to direct it into a container.
This may take a few tries as the control will lock out if no flame is detected after about 10 seconds.
on the burner there is an oil pump usually on the left if European manufacture .As you look at it there will be 2 nuts facing you . slacken the Bottom nut 15mm spanner usually until oil flows. Tighten and push reset. Ps ensure that all valves are on, fire valve opposite thread to open . turn anti clock
Be sure the valve from tank to furnace is open, and replace the filter, usually located either after the shutoff valve on the tank or just before the line goes into furnace
Nosdas right, but when purging the air you must disconnect from boiler end and bleed the oil into a bucket,as there will be oil in the line before the air lock.
You have an air lock in the oil pipe line to your boiler. Loosen the connection at the boiler and let the air out.
Was the tank completely empty before the fill?? i'm wondering if you have crud from the tank bottom in there??
Hows your pressure bar gauge??
