Summerset IRB-SZR Infrared Sear Burner for Sizzler Grills
15,000 BTUs of Focused Infrared Heat — Drop One In and Your Sizzler Becomes a Steakhouse Searing Station
The Summerset IRB-SZR replaces a standard main burner in any Sizzler gas grill to deliver intense, even ceramic infrared heat — the kind that builds a deep crust without overcooking the center.
The Summerset IRB-SZR Drop-In Infrared Sear Burner is a ceramic infrared upgrade burner designed specifically for Summerset Sizzler gas grills. It drops directly into any main burner slot in minutes, replacing a standard tube burner with a 15,000 BTU ceramic infrared element that radiates intense, even heat across the searing zone. Infrared burners work differently from conventional gas burners — instead of heating the air around the food, they radiate heat directly at the grate surface, reaching high temperatures faster and holding them more consistently. The result is the kind of crust formation that separates a properly seared steak from one that's merely cooked through. Backed by Summerset's Gold Standard Lifetime Warranty.
What the IRB-SZR Does That a Standard Burner Can't
Infrared heat works fundamentally differently from a conventional tube burner — and that difference shows up directly in the quality of the sear you get at the grill.
Intense, Focused Heat — Crust in Seconds, Not Minutes
15,000 BTUs radiating directly from the ceramic surface hits the grate hard and fast, generating the high surface temperatures needed to caramelize meat proteins and build a deep crust before the center overcooks. The sear you want from a steakhouse, from your own backyard.
Ceramic Infrared Surface — Even Heat Across the Full Searing Zone
The ceramic infrared element radiates heat evenly across its surface rather than concentrating it in hot spots above burner tubes. Every square inch of the searing zone gets the same intense heat — no cold patches where the sear doesn't form, no flare-up hot spots that char the outside before the inside is ready.
Replaces Any Main Burner Slot — No Modifications, No Tools
The IRB-SZR is sized to replace a standard main burner in any Summerset Sizzler grill. Lift out the existing burner, drop in the infrared element, and your dedicated searing zone is ready. No drilling, no adapters, no permanent modifications — and the remaining burner slots stay exactly as they were for standard grilling.
Why Infrared Searing Produces a Better Crust Than a Standard Gas Burner
A standard tube burner heats the air inside the grill hood, which then convects heat toward the food. Infrared burners skip that step entirely — the ceramic element converts gas energy into radiant heat that transfers directly to the grate and the food surface without heating the surrounding air first. This means faster surface temperature rise, less moisture loss from the meat during the sear (steam from the cooking air is reduced), and more consistent contact heat across the zone. The result is a harder crust, more Maillard reaction, better flavor development — and it happens in a shorter time window, which protects the interior temperature of your cook.
Who the IRB-SZR Is For
- Summerset Sizzler owners who want steakhouse sear quality — the IRB-SZR adds a dedicated high-heat infrared zone to any Sizzler grill without buying a new grill.
- Cooks who regularly do thick-cut steaks, pork chops, or fish — cuts that need intense surface heat to form a proper crust before the interior overcooks benefit most from infrared searing temperatures.
- Grillers frustrated by uneven sear results from standard burners — the ceramic element's even radiant heat eliminates the cold patches between burner tubes that prevent consistent crust formation across a large piece of meat.
- Sizzler owners who want to expand cooking versatility — keeping standard burners in the other slots alongside the infrared zone lets you sear on one end and finish or hold on the other in the same session.
- Buyers who want a performance upgrade without a full grill replacement — the drop-in installation means you get infrared capability from your existing Sizzler without any permanent modifications or additional purchase complexity.

Summerset IRB-SZR — Frequently Asked Questions
Which Summerset grills is the IRB-SZR compatible with?
The IRB-SZR is compatible with both the Summerset Sizzler Series (SZR32, SZR40) and the Summerset Sizzler Pro Series (SZPRO32, SZPRO40), including all LP variants. It is not compatible with the TRL, TRL Pro, or Quest Series — those grills use separate infrared sear burner SKUs (IRB-TRL and IRB-QST respectively). Note: installation on newer Sizzler Pro models may require professional assistance as the burner retention system differs from older models — confirm the installation method for your specific grill before ordering.
How does the drop-in installation work?
The IRB-SZR replaces a standard main burner in any compatible burner slot — no orifice change, adapter, or valve modification is required. Remove the existing burner from the slot you want to convert, drop the infrared element into position, and connect it to the existing valve. No drilling, cutting, or permanent grill modifications are needed. Note: some owners of newer Sizzler Pro models have reported that physically removing the existing burner can be more involved than older models due to changes in the burner retention system — if you are unsure about the process for your specific grill, contact Summerset or a qualified technician before attempting the swap.
Can I still use my other burners normally after installing the IRB-SZR?
Yes. The IRB-SZR replaces one main burner slot; the remaining standard burners in your Sizzler operate exactly as before. You get a dedicated infrared searing zone on one part of the grill while using the remaining burners for standard grilling, roasting, or holding temperature. This is how most cooks use the setup — sear on the IR zone, finish on a lower-heat standard burner.
Which burner slot should I put the IRB-SZR in?
Most cooks install it in one of the outer burner positions so the searing zone is at one end of the grill and the remaining standard burners are available for lower-heat cooking on the other end. This gives you a clear separation between the high-heat sear zone and the rest of the cooking surface. The specific slot is ultimately a matter of your cooking workflow — there is no wrong position functionally, but the outer slot is the most common preference.
How is infrared searing different from a standard gas burner?
A standard tube burner heats the air inside the grill, which then convects heat toward the food. An infrared burner converts gas energy into radiant heat that transfers directly to the grate and food surface without heating the surrounding air first. This produces faster surface temperature rise, more consistent heat across the zone (no cold spots between burner tubes), and less ambient moisture from steam — all of which contribute to more consistent crust formation and better Maillard reaction on the surface of the meat.
Can I use the IRB-SZR for slow cooking or low-and-slow barbecue?
No — an infrared burner is a high-heat searing tool, not a low-temperature cooking zone. It is designed to run at intense temperatures for fast crust formation. For slow cooking, roasting, or holding temperature, use the remaining standard burners in your Sizzler with the infrared zone off or on its lowest setting.
What foods work best with infrared searing?
Thick-cut steaks, pork chops, lamb chops, and large fish fillets are the most common applications — cuts where you want maximum surface browning with a controlled interior temperature. Infrared searing is also useful for finishing a reverse-seared roast (cook low and slow first, then hit the IR zone for the crust) or for quick vegetable charring. Thinner cuts can be done on the infrared zone but require shorter contact times to avoid overcooking.
How do I clean the ceramic infrared element?
Run the infrared burner on high for 10–15 minutes after cooking to burn off any residue — the intense heat of the element will incinerate most grease and food debris. Once cooled, use a soft brush to remove any remaining ash. Do not use water or liquid cleaners directly on the ceramic element, as thermal shock from cold water on a hot ceramic surface can crack it.
What is Summerset's warranty on the IRB-SZR?
The IRB-SZR is covered by Summerset's Gold Standard Lifetime Warranty on burners as a gas grill component. Warranty covers replacement parts only — labor is not included. Must be registered within 30 days of purchase with proof of purchase and photo documentation; valid for the original purchaser at the original delivery site only.
