Preparation

• 1). Have a licensed plumber install a natural gas line where you want to set up the grill, if one does not already exist.
  
  
• 2). Obtain a conversion kit from your grill's manufacturer.
  
  
• 3). Combine 1/4 cup dish soap with 1/4 water in bowl and set aside.
  
  
• 4). Remove grates and burners in order to access connections.
  
  
• 5). Turn off the gas at the meter.
  
  

Installation

• 1). Disconnect the existing LP gas regulator from the grill.
  
  
• 2). Unscrew the old burner orifices, which control the flow of gas to the grill. Connect the new orifices according to the manufacturer's instructions included with the conversion kit.
  
  
• 3). Connect the gas line to the grill, using thread tape on the connections for a good seal.
  
  

Test for leaks

• 1). Apply the soap and water solution you prepared to all the connections, using a paint brush.
  
  
• 2). Turn on the gas.
  
  
• 3). If you see bubbles at any connection, you'll need to reseal that connection, as the bubbles indicate gas is escaping.
  
  
• 4). Clean the soap solution off the connections with clean water, as some dish soaps can corrode pipes. Dry with clean rags.
  
  
• 5). Reassemble the grill, replacing the grates and burners.
