How large should the orifices on my 52,000 BTU (4 burner) natural gas BBQ be? How long should it take to heat up to 500F?
I know you may not be a gas fitter and you are definitely not my gas fitter, but I am trying to convert my new propane Broil King Sovereign XLS 90 (http://www.broilkingbbq.com/grills/series_15.html
) to natural gas. Google has told me that the orifices on the valves need to be widened, since NG is regulated at a much lower pressure than liquid propane. I've had a gas fitter friend of my dad come and swap the propane regulator for a NG hose and hook it up to my supply, but he only widened the orifices from a #57 bit size to a #55 bit size.
Each of the main burners are rated to output 13,000 BTUs, while the side burner is rated at 10,000 BTUs and the rear is rated at 18,000 BTUs. What bit size should I use so that I get the proper power out of my shiny new toy?
Finally, I came across this semi-helpful chart on the web (http://www.joppaglass.com/burner/lowp_chrt.html
) but I believe my gas line (Toronto, Ontario) is regulated at 2.5" WC.
So, is there anybody knowledgeable with gas and BBQs that can help me crank the power of my grill without melting the entire box?
