It seems to be leaking from a brass cylinder about 1 inch in diameter with a small diameter (circa 4mm) brass oil feed pipe running to it. On the right hand side of the burner there's a spring loaded iron air flap plate and this had a mist of oil on it with a little accumulated on the base plate of the boiler casing below.
Sod all to go wrong or that's what I'd been hoping anyway since I moved in here in 2012. Can anyone suggest a logical sequence of checks to make? I have a DMM and all necessary tools and it looks fairly simple in there compared to modern boilers. Too late to do anything tonight but tomorrow I must get the tools out. It would help if it said a bit more about where they are! Alternatively maybe the photo resistor is not detecting the flame properly. Looking at the fairly vague manual there are electrodes which should be adjusted to a 3-4mm gap. My first thought is that as the boiler has tried to fire then the water thermostats and zone valves must be ok and this is an ignition problem. Pressing the reset to try again had no better effect.ĬH pump is running and everything else looks normal.
The reset button has a red lockout light which glows if the burner has tried to fire but failed and this was indeed glowing. It failed to light this evening for the first time. Oil Ch boiler, Boulter Camray 2 model 51/67 circa 1990 vintage with a RielloĤ0/3BM burner.
