I am replacing a gas burner assembly on a Brinkman 4 burner propane grill.

After receiving the part, I went online to download a manual.

All I could find is lighting and maintenance instructions, but no
exploded diagram showing how the parts fit together.

Any ideas how to find out that information ?

Thanks.

Ordinarily, people replace parts in the reverse older in which they
came apart.

Try searching using the specific Model number?
