Weber Flavorizer bars are inverted-V pieces over the burners. They catch drips and keep liquid off the ports. When they rust into lace, every steak bastes the burner. People then buy new tubes. The tubes were the victim. Ordering 310 bars for a 210 (or the reverse) is how this job goes wrong.
When they are done
- Hold a bar to the sky. Daylight in the peak over a burner → done.
- Enamel gone and steel thin at the notch ends → done.
- Surface rust on the sides is ugly and still functional.
- A warped bar that no longer sits in the notches will slide and dump fat → done.
- Cleaning can remove fat. Cleaning cannot add steel. Intact but filthy → degrease.
Measure, do not guess
- Grill cold. Lift the cooking grates. Count bars: two on E-210, three on E-310. Count is not enough — a 310 bar is longer.
- Measure length end-to-end and the width of one V. Write the numbers next to the model from the data plate.
- Search Amazon or BBQGuys for Weber Spirit E-210 flavorizer or E-310 flavorizer. Compare listed length to your tape. Older Spirit and Spirit II kits can differ. We do not print an ASIN or a price.
Forum numbers (7635 / 7636) are clues for an official diagram, not a guarantee for your serial. Wrong-length bars that “almost” sit will walk.
Swap
- Tank off if you will be leaning into the box. Gloves — rusted edges cut.
- Lift old bars straight up. If seized in the notches, work them; do not pry the firebox flange.
- Scrape the notches so the new bars sit level.
- Set new bars with the peak centered over each burner tube. A gap you can see from above is a drip path.
- Refit grates. Confirm the bars did not shift. Preheat and look: bars take the flare, not the tube.
Aftermarket versus OEM shape
- Stainless lasts longer if the gauge is honest. Thin stainless warps.
- Compare weight in product photos and the return policy. This site does not review brands.
- Porcelain-enameled bars chip if you dump them in a sink. Treat them like porcelain grates.
If you skip this job
- You will clean ports on a schedule, then replace tubes.
- Flavorizers alone do not justify a new grill. Flavorizers plus a lace firebox do. See repair versus replace.
