Summerset Infrared Sear Burner for Quest - Model IRB-QST
18,000 BTUs of Infrared Heat — Steakhouse Sear in Your Own Backyard
Drop it into your Quest grill in place of a main burner and turn one zone into a searing machine.
The Summerset IRB-QST is a drop-in infrared sear burner that upgrades your Quest Series grill with intense, even, high-heat searing power. Delivering up to 18,000 BTUs through a ceramic infrared element, it lays down restaurant-quality sear marks and locks in flavor — the easy add-on that builds a dedicated sear zone right into the grill you already own.
Why You'll Love the IRB-QST
One simple swap, and your Quest grill earns a true sear zone for the cuts that deserve it.
Steakhouse Sear at Home
Intense, rapid heat gives thick steaks and chops a deep, caramelized crust in seconds — no more gray, evenly-cooked-through meat where you wanted a sear.
Infrared Ceramic Intensity
The ceramic infrared element reaches up to about 1,600°F for fast, even, edge-to-edge searing heat that conventional burners can't match.
Swap In, No Drama
A plug-and-play design lets you remove a main burner and drop this one in its place — a straightforward upgrade, not a project.
Made for Your Grill
Designed to replace any main burner position in Summerset Quest Series grills, so it fits clean and works the way it should.
Why Infrared Searing Wins
Infrared burners heat a ceramic surface that radiates intense, direct heat straight up into the food, rather than relying on hot air that fluctuates with the breeze. The result is a blistering, even sear that builds a flavorful crust fast — perfect for finishing a reverse-seared ribeye or putting steakhouse marks on chops, while the rest of your grill keeps handling everything else.
How It Installs
- Make sure the grill is off and fully cool, with the gas supply shut off.
- Remove one of the existing main burners from your Quest grill.
- Drop the IRB-QST sear burner into that position.
- Reconnect per the instructions, check for a proper seal, and you're ready to sear.
Always follow the included instructions and your grill's manual for exact installation and gas-connection steps.
Who the IRB-QST Is For
- Summerset Quest grill owners who want a dedicated, high-heat sear zone built into the grill.
- Steak and chop lovers chasing a deep, restaurant-quality crust at home.
- Reverse-sear cooks who need a blistering finish after a slow cook.
- Grillers customizing their setup who like swapping a main burner for a purpose-built sear burner.
