The steps for converting a Home Depot Ducane Stainless steel grill, from LP to natural gas,are as follows. 
 

1. Purchase or borrow numbered drill bits(you can use the conversion chart to just buy the drill bits you need) You’ll need a hand held bit driver or you could use a pair of vise grips to hand drill the orifice.. An electric drill could easily break the small bits or damage the orifice.
2..Use the LP-Natural gas BTU to numbered drill conversion chart to determine which drill bits you’ll need for each orifice. If the grill spec plate doesn’t show the individual BTU output per burner you’ll have to do more research or guess using the total output of the grill. The spec plate for the Home Depo Ducane grill shows each burner rating.You’ll have to use the drill bit that gets closest to the BTU output listed.

3. Starting with the front control panel remove the two screws on each side and pull the panel carefully away from the front of the grill. Remove the burners form the main cooking area of the grill. You can actually drill out each orifice by placing the hand held drill bit holder with the correct bit from the inside of the grill through the burner hole to drill the orifice.

It is possible to drill the orifices without detaching the control panel but you can’t easily see the orifice and you can’t remove the burners in the Ducane without removing the control panel.
