Re: Orifice size for natural gas burners?

Quote from: Pizza_Not_War on Yesterday at 06:33:08 PMYou need to know what gas pressure is coming in , what the desired output is, etc. I advise hiring a gas filter, plumbing person.

I am a retired Plumber/General Contractor, but I haven’t found any charts to recommend jet/orifice sizes.  My running pressure at this outlet with the old “holes drilled in a 1/2″ pipe” is 5.5″ WC. Is there a chart I can select jets from or can anyone look at or can anyone read what their jet sizes are?

Thanks!
