Step 1 Understand the basic electrical circuit. Source > Control > Load > Return path to source

This is a basic electrical circuit.

1. Source = two 1.5 volt batteries
2. Load = light bulb
3. Control = manual switch
4. Return path to source

Note that the load and control can be reversed. The load can be on the Source side or the Return Path side of the circuit.

From that basic understanding of electricity, you can build any analog electrical control circuit to operate a boiler.

Go very slowly and know when you need to bring in help. It takes years to get really good. Mad Dog

what 3rd pipe? i think that contraption is screwed in to the manifold of the convector.

His CO2 is 5.42 %

C0=4

O2 is 10.2%

How is this grossly rich?

Its the opposite he is short of gas and the fire is too lean.
