Boulter Camry 2 Boiler Manual
Hi,Was wondering if anyone could offer some advice on a lockout problem I have with my Camray 2 oil boilerDescription of problem is as follows.From a cold start The fan runs. The ignition system sparks. The burner ignites.
I can now play with the thermostat and switch the boiler on/off (before it has a chance to heat up too much)At some point the boiler will switch off when the water is hot enough. It will now not reignite till allowed to rest for a long period of time.From a warm start The fan runs. The ignition system sparks. The burner does not ignite.
Motorola manual download. The lockout activates after the ignition runs for several seconds. There is a bi-metalic strip that heats up and activates the lockout. I have verified this is happening every time it fails to ignite.There is a second bi-metalic strip and magnet in the control box that, from what i can tell, serves to speed up a warm start by firing the ignition spark immediately upon pressing the reset button. I have reset this manually to prevent this from happening when the system is warm to see if this is the cause, but it had no effect.I believe i have plenty of oil pressure - no real way of checking, but symptoms do not seem to indicate this to be the problem.What seems to be happening is the solenoid controlling the oil flow is sticking. Is this a known issue?
My reasons for this are based on: I have probed (with a multimeter) the solenoid control in both the working and not working conditions and the voltages are identical. I have watched the burner output and see no oil being vaporised from the burner when the ignition spark is firing.Is there any way to test this i.e to force open to valve. So far this is only a theory and I don't know any way to verify this. Any ideas greatly appreciated.Thanks Steve.
Srf,Most un-lightly that the solenoid is sticking, as both measured voltages are the same, but will go along with your assumption that the valve is not releasing any oil as no vaporisation is occuring at ignition. Can you trace where the 'Open Sol.' Signal is coming from? As you have measured the supply voltage to the sol. You could force the issue by disconnecting the sol. Feed supply and connect a separate supply to the sol.
And check it operates (little click), with the oil supply off, but take CARE. Some good news, some bad.1st the good.The boiler is now working2nd the badI don't know why!!Thats not completely true. I removed the control box to measure the resistance of the solenoid coil and to make sure I was measuring the correct leads I moved them around. I then measured the resistances and reassembled.

It has not failed since then and I'm not about to touch it again to verify this is what fixed itSo it was most likely a open circuit in the leads connecting the solenoid coils.Out of curiosity, can anyone tell me what the 3 connections to the solenoid coil are - labelled A, D and C - I guess C is common, but what are the other 2?thanks.
Originally established in 1970, Boulter Boilers were acquired by Buderus Heitztechnic, a member of the Buderus Group in 2003. Boulter boilers was a recognised brand in the UK oil heating industry and ironically, as Boulter's operations were being integrated into the Buderus group, Buderus were acquired by Robert Bosch GmbH - represented in the UK by Worcester Bosch - one of Boulters competitors.As well as stocking detailed ranges of Boulter boiler spares indluding baffles, thermostats and divertor valves for the popular Camray boilers, PHC carry vast stocks of Riello spare parts, the pressure jet burners utilised on the majority of Boulter oil fired boilers.
