Where grease goes in a pellet grill

If grease is pooling somewhere odd, you need to know where it was meant to go. Start there, then look for what's in the way.

Parts and names change from one model to the next. What follows draws on two makers' own cleaning guides, so treat it as a general picture and check your manual for your layout.

The path, top to bottom

Fat comes out of the food as it cooks and drips off the rack. Traeger puts it plainly: grease is bound to accumulate when you cook.¹

Camp Chef describes the next layer. The drip tray sits below the bottom rack and above the heat deflector plate.² So the tray is the first thing that catches the drips, and the plate sits under it.

From the tray, grease is meant to run to a catch point. Weber says the bottom tray on its own grills is designed to maximise the flow of grease to the catch pan.³ Camp Chef points to a grease channel in the drip tray.²

The last stop is a bucket. Camp Chef describes a small bucket that hangs off the back of the grill and catches drippings.² Some Traeger models use other names for this chain. Their guide lists a grease governor (a cap), a grease tube and a grease and ash keg.¹

If grease is pooling on the tray

Work through these in order.

1. Look at the channel first. Camp Chef says the grease channel is the spot that tends to collect the most buildup, and it tells owners to clean every crevice, the channel included.²
2. Check the liner. Weber says creases in foil can create barriers to the flow of grease.³ The page on foil and drip trays goes through what two makers say.
3. Check that every part is back where it belongs. Traeger's cleaning steps end with putting the heat baffle, drip tray, liners or foil, bucket liners and grates back in.¹
4. Check the bucket. A full bucket has nowhere left to take the fat. See Grease buckets and liners.

If the bucket fills faster than you expect

Camp Chef tells owners to keep an eye on the grease level in the bucket.² Traeger says high-fat foods mean the grill needs cleaning sooner.¹

Emptying a bucket is a hot, messy job if it's rushed. Wait until the grill and the grease have cooled. How to get rid of the contents is covered in Disposing of used grease safely.

Why the path matters

Traeger lists spilled grease and an unclean grill among the possible causes of a grill fire.⁴ Why grease fires start on a pellet grill goes into it.

Some things are model-specific. Which part hangs where, whether there's a chimney or a downdraft, how the drain is fitted: your owner's manual is the source to trust for all of it. Camp Chef itself says to read the manual that came with the grill.²
