Thermocoupling on a Honeywell Economy Plus EP50B Boiler

Hi. I am trying to replace the Thermocoupling on this above boiler but in all the confusion of cleaning the unit, i forgot where to plug the other end with the stub on it,i believe its the switch part which is supposed to screw into somewhere. I have a Corgi registered friend coming in 3 nights to check it all but i wish to put the new thermocoupling in to see if it fixes the problem, but i cannot find any online diagrams to show where to plug the other end into.
If i could be sent a picture of the boiler without the cover on or a diagram showing how and where to plug the honeywell/ Glow worm thermocoupling in,that would be awesome!
Hope to hear back soon.
Best Regards
Matt Garner

The thermocouple most likely plugs into the gas valve, the box with the gas control on it.

Boiler ignition failer


Try adjusting the gas to air mixture and flow rate. I don't work well in very cold weather, either. I think that's fairly typical. Even a diesel engine is difficult to start in cold cold weather. Perhaps heating the room where the boiler is would help or at lest insulate the room well. Including stopping any drafts that may be causing a windy condition in or around the combustion chamber.

There is a flow sensor in the circuit and it is not sensing the lower flow from just the hot water. When you put it on heat though it does.

Check voltage at the gas valve and at the thermocoupling. If you are reading more then 24 volts at the gas valve then replace it, or less then replace it also
