boiler fires up for a few seconds then goes off, continues to spark. After a few attempts the lock out led comes on. Works when the combustion chamber is off.
check flue was fitted correctly as the white seal bends when pushing the elbow into the flue and doesn't sit right.
Fault only starts after the warrenty period is over
Remove the complete flue clean and pour water in the top of the boiler to clean out the heat exchanger. Done 3 of these in the past year.
Here's 1 for commercial oil burners. I'd say Croppie's seen this. Have seen this happen a couple of times on Riello RL burners.
If the plant room door is open on a sunny day, sun shining in can make d burner go to lock out.
Photocell can pick up light shinning down boiler sight glass, say when boilers up to temperature, photocell picks up some light, the panel thinks there's a flame like a big lump of carbon on d head burning, and locks panel out.
You'll go out on call, Murphy's law it'll be a dull day and there'll b no apparent fault.
You wanna read that again!
You're advising for a expansion vessel to be fitted on the return yet you had a nightmare when you fitted it on the return!!
