This burner is fitted to trianco eurostar wm 50 in the wall boiler
Serviced a month ago and keeps locking out at the control box, the boiler will run for a few days then lock out at any time in the day.It will restart after pressing the reset button. carried out another combustion test today c02 10.6% fgt171c ratio0.004 smoke zero and the pump pressure 110psi steady.
Replaced the control box,coil,photocell and another nozzle.
Upon inspection the blast tube had slight sooting and there was dark staining around the nozzle.
I am oftec registered and this is the first time in many years I cant nail this problem!
any help will be very welcome
Thanks
Steve
