Forgive me, I was addessing Mr. hooks and not the OP as the thread advanced, in conjunction with ASCO type valves using Jet style burners.This is horrible advice. The original poster is using a VR8304 Honeywell gas valve. It is rated for not more than 0.5 psig. Just for ****z and giggles I called Honeywell and the technician said if you put even 1 psig of pressure through the valve you risk damage.
What LP gas regulator delivers .5 lbs psig then , the low pressure regulator on the primary side of the HoneyWell gas valve, what pressure is delivered from the 20LP ? well that depends .....anywhere from 6psig to 200psig .
Perhaps the OP will comment on his setup and results
