I'm looking for help in figuring out how to automate my 1.5 bbl propane fired system. I'm using BG14 burners with 30 psi regulator. I have a PID temperature controller to activate the gas valve, but I haven't had success getting auto-ignition to work reliably.
Attempts so far:
* pilot light - blows out when the valve is shutoff
* 12v hot surface igniter - worked for a few minutes, but the longer it ran, the less reliable the auto-ignition.
Any ideas would be appreciated.
