Replacement BBQ grill parts for Ducane Affinity S 3400 S3400-LP
On this page you'll find all of the parts that fit model Ducane S3400-LP. We might not show the part you need here but we may still have it, or a functional equivalent. In this case, try the category buttons on the right. For example, if your looking for a cooking grid and there are none here, click the cooking grids button to see all of the cooking grids we have for Ducane grills. Knowing the dimensions of your existing part will help you find the right part.

To get the correct Ducane S3400-LP BBQ parts
  • You should measure your existing parts and compare them to what we show here. This is best done with them removed from the grill.
  • Verify your Ducane model number by checking the CSA appliance tag on your grill to make sure you have the correct model number. Do not rely solely on the owners manual as these are frequently mixed up at retail stores when the grills are assembled. You'd be surprised at how many folks have the wrong owners manual.
