Thread: Safety solenoids for gas kiln?

Safety solenoids for gas kiln?
This is not really metalworking, but I'm looking for some help with a gas burner safety setup.
I have a functioning burner witb a manual shut-off valve and a pair of gas solenoids that came of a functioning commercial kiln. The two solenoids are in series and one of them has a very small copper tube attached which I suspect goes to a pilot light. Their function would be for one to shut the main burner off if it blew out (to prevent gas entering a red hot kiln). The second one presumably to turn everything off if the pilot went out, e.g. if the gas bottle went empty during firing (again to stop gas going in when a new bottle was connected).
The solenoid coils are 240V AC.
So what is needed to switch them off when these fault conditions arise? What can sense them and what controls the coil power?
Lastly, there are two separate insulated spark electrodes on the end of the burner (I assume for safety/redundancy). Is an ignition spark kept going all the time on a kiln to ensure any gas is ignited before entering the kiln? If so, how is that done?
I asked a friendly gas installer, but he said he would rather a) not enlighten me and b) also not install anything for me because his insurace won't allow him to do anything other than domestic heating and hot water...

You might want to find a potter. They know bits and pieces from this stuff. (I can't really remember ) Some have been forced, like you, to learn about this stuff cos the plumber won't tell them. You can't find anything with trusty google?

I'm working on the controls with and for a potter friend of mine.... he has enlisted my help with the research and installation. The burner and solenoids were sourced by my father-in-law potter who passed away about 15 years ago... he knew what to do, alas...
Reading myself into the topic, but had hoped someone here could speed up the process..
Here are a couple of photo of a burner and solenoids, they look no different to lawn sprinkler or washing machine solenoids....

Have you this company before to make up two gas burners with auto shut off swithches if the gas flame went out.
