I had a problem with a gas-powered boiler that was not working, if that can help me I put the links of the discussion which allowed me to solve this problem
I'm very sorry,
I do not yet master all sections of this forum.
that said, I posted the same message on the steam forum, I had the opportunity to have an answer that solved my problem. I will create a topic for people who will be in the same problem.
Thanks for your help !
