Hi,
I have a Ideal Mexico Super 2 on a gravity feed system. I drained down the system to change 2 radiators. Filled the system back up, bleed everything including the pump and vent valve next to the boiler.
The boiler stat is on 3.5, but will not fire up when heat is called from the room stat. When the room stat calls, the pump engages and the boiler stays at pilot.
I have changed nothing apart from the rads and the system worked perfectly fine beforehand. The system does not have a 3 port valve.
Any ideas appreciated. Thanks.
