Unfortunately the ECO is a one shot device........when they open it's permanent and part of the gas valve.
Pushing knob in at pilot position would allow gas to pilot.
Pilot flame heats thermocouple which sends mV signal to magnet which lets gas control continue to send gas to pilot....then a mV signal goes thru ECO back to thermocouple which completes the circle.
Magnet only needs 12 mV or more to stay open.
If you heat thermocouple with a BBQ lighter can you get any gas flow?
If not then suspect ECO tripped.....new gas valve!
Is it time for your medication or mine?
