In Reply to: Converting An LP Gas Grill To Natural Gas? Posted by: Timmy on June 28, 2001 at 07:06:03:

I recently received a " Sam's Member's Mark Model Y0005XC-2 LPG gas Grill". I need the instructions or Drill size for drilling the orifice and burner size holes bigger for the proper gas flow and heating of the grill.

What you need is to contact the manufacturer about obtaining an LP to NG conversion kit for safe and proper operation. One does not just simply "drill" larger holes in orifices and burners. Doing such will void any warranties.
