I have read countless threads and now I have contacted the company with no luck. I really need some advice on which burner to use for low pressure propane. I am not confused on the pressures. I fully understand the 11" water column or .5 psi for low pressure. 1)What I would like to know is who uses the 23 tip jet burners for this application and more specifically what are the size of the jet orifice for low pressure application.
I bought one from Thunder group and they could not tell me if it could be used for LP LP or what the orifice size are. I tried on low pressure and it seems like it works well but its a beast on high. Is there a difference in the sizes? When on low pressure I had a little yellow in the tips and it left no soot behind.
Next question is I have the Blichmann floor burner and wanted to convert that to low pressure. I drilled out the jet 3/32 but get a really yellow flame that leaves a lot of soot behind. Should I fill the whole and go smaller? I have looked at the chart that compares (Low Pressure Orifice Chart
) orifice to BTU output. Is it better to start small and work my way up? Also this burner has been used for high pressure many times so I don't think it's burning any paint/oil off.
Thanks ahead of time for some help.
