Just curious what this is and what it does.

in Gas Heating
Hello all, first time posting here. I was wondering if any pro could tell me what this is and what it does.
It's just screw on to pipe and its wired to a carlin 60200-02fr relay T T screws .
Does anyone know what it is and what it does for I never seen it before.
Thank you for your time with any insight you can give.

You can choose to do what you want, but you cannot choose the consequences.
If you have the free time could you explain what its purpose is and why its used (either a manual reset limit switch or a draft spill switch). I understand if you dont have the time I do appreciate your first response. I just like to learn new things and this one puzzles me.
Thank you again for your time

Certainly a good idea.
Often seen on a small angle bracket so the spilled gases would get to it quicker.
Does anyone know what the limit settings should be for the various fuels?
I see some old equipment that should have this safety added.
Thank you 👍👍

If so- whoever installed the burner did not change the barometric to the proper double-swing gas type. And that blocked-flue switch is the wrong part.
Field Controls makes the MG1 gas-type barometric for smaller units:

and the M+MG2 for larger ones:

and the blocked-flue switches that go with them. The GSK-3 is most commonly used on smaller units:

If you tell us where you're located, we might know someone who can straighten that mess out, and test it with a digital analyzer to make sure it's running safely. Or, have your friend post here.

Yes it is a gas fired burner with a carlin burner. He was having problems with his system today and asked for help. I know a little about oil fired burners due to the class I took. I know nothing about gas (except similarity of some parts) I told him he would have to contact a professional because I dont know enough of gas system or want to be responsible for mishaps. His one question was about that part and I never seen it before. So curiosity got the best of me. That is the only reason I asked.
The good news is he had someone come today and found out what was wrong with his system.....his relay was bad and needed to be replaced.
