On this boiler there appears to be two live connections to the gas valve
- one presumably for the pilot and another for the main valve. The PCB
may sequence these, and possibly turn off the pilot once the ignition
electrode detects the main burner firing.


Yep, that@s exactly what seems to happen

Thanks John

In which case, I would have to concur, shagged gas valve...

(have seen this on other mexico boilers - although normally the manual
pilot type. One that failed to fire at all, and one that failed shortly
after main burner ignition as the valve warmed up).
