    What is the input to the unit? How many burners are there? What is the outlet pressure from the gas valve? How did you come to those numbers for LP and Natural gas? Do you have a combustion analyzer? If so be sure and do an analysis after the conversion.

    Oh ! I just figured it out . The jet size is the drill size and I got the info size from the install manual on the high altitude page.
