Summerset Infrared Sear Burner for Sizzler Grills: A steak searing spot in your existing grill
The Summerset Infrared Sear Burner for Sizzler Grills is a drop in burner that replaces one main burner. Infrared means it heats the food with direct radiant heat instead of hot air. The grate over that one spot gets much hotter, and a steak gets a dark crust in about a minute per side. It fits every Sizzler and Sizzler Pro grill, in any burner position. It runs at 14,000 BTUs in a Sizzler Pro and 12,000 in a Sizzler, matched to each grill’s gas system. Summerset backs it with a lifetime warranty.
You lift out one main burner and set this one in its place, with no tools and no cutting. Sear on it first, then move the meat over the regular burners to finish. It is the cheapest way to get a steakhouse crust on a value grill. Have a TRL Pro instead? See the Summerset Infrared Sear Burner for TRL Pro Grills. The Summerset Infrared Sear Burner for Sizzler Grills ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
FAQ
Which grills does the IRB-SZR fit?
Every grill in the Sizzler and Sizzler Pro series. The same drop-in burner works across both lines: in a Sizzler Pro it runs at 14,000 BTUs, and in a standard Sizzler it runs at 12,000 BTUs, matching each grill’s gas system. If you own either series, this is the sear upgrade made for it.
What is an infrared sear burner, exactly?
Instead of heating air like a standard flame burner, an infrared burner focuses intense radiant heat directly at the food — the same principle steakhouses use to crust a steak in minutes. Dropping the IRB-SZR into your Sizzler creates a dedicated high-heat zone; see our infrared gas grill category for grills with infrared already built in.
Is installing the Sizzler sear burner difficult?
No — Summerset calls it plug-and-play for a reason. The IRB-SZR simply takes the place of any one main burner in your Sizzler or Sizzler Pro: lift out the original, seat the sear burner in its position, and you are grilling. No cutting, no rewiring, no professional installation required.
Why does the listing show two different BTU ratings?
Because output depends on the host grill: the burner performs at 14,000 BTUs installed in a Sizzler Pro and 12,000 BTUs in a standard Sizzler, reflecting each platform’s gas delivery. Either way you get concentrated radiant heat that sears far more aggressively than the raw number suggests on paper.
How do I get a steakhouse crust with it?
Preheat the infrared zone for several minutes until it glows, pat the steak dry, and sear 60 to 90 seconds per side before finishing over your Sizzler’s standard burners at medium. A dry surface plus the IRB-SZR’s radiant intensity is the entire steakhouse secret — browning happens before the interior overshoots.
Do I lose normal grilling ability by adding it?
Only the single burner position you replace — the rest of the grill cooks exactly as before. Most Sizzler owners put the IRB-SZR at one end, creating a sear station beside their conventional zones, and you can always lift it out and reinstall the original burner whenever you want the grill stock again.
Is this accessory covered by a warranty?
Yes — the IRB-SZR carries Summerset’s Gold Standard Lifetime Warranty, the same industry-leading coverage as the grills it drops into. For a component that spends its whole life over open flame, lifetime coverage is a meaningful difference from generic aftermarket sear burners sold on spec alone.
