Read the manual. Read it again.

Use coloured wires, and use them with the colours the manual suggests.

Use the correct types and sizes of wires.

Keep it neat.

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.
