Hi
What is the make/model of the boiler (about a year or so old) that has a small plastic cover (2 screws) on the back of pcb case which contains a short plastic stick, which is then used to adjust the CO2 level for combustion through a potentiometer?
It's a premix burner
I think it might be a Glow Worm but just can't remember
Long story .... but it's been bugging me!....
