Hi There, We ran out of oil....more or less. I believe the oil boiler now needs bleeding, as it will only come on for a minute or two, often less, then it turns itself off. Pressing the reset button means it lights again for anywhere between 30 seconds and 2 minutes, but no more. There's mild heat in the radiator, but very mild. Because of having the tank refilled today, I presume this is a bleed issue, but I may be wrong. It was serviced only a fortnight or so ago. I have taken some photos of the boiler - it says the make is Beta (it's old!). 1. Can anybody point me to where I would find the bleed valve? 2. Can anybody remind me what the red dial is for? I remember being told by our original heating engineer, before he retired. Have had issues with the motor in the 2-way valve in recent times which was causing house and system to trip, but have mostly resolved that without replacing it. The last thing the heating did, though, when the oil ran out, was trip the circuit... Any help greatly appreciated. Would prefer to learn to bleed this myself.
