Summerset Grill Liner for Double Side Burners: heat protection for a wood framed island
The Summerset Grill Liner for Double Side Burners is a stainless steel sleeve that lines the island cutout for a Summerset double side burner. It is for an island framed in wood or any other material that can burn, because the heat from the burner would otherwise reach the framing. A side burner throws heat down into the cabinet under it, not just up at the pot. Liner means a double walled stainless steel box, one inch thick, that goes into the cutout first, and the burner drops into it. It fits only the Summerset double side burners. Each appliance in the island needs its own liner. It is built from 304 stainless steel, the grade that holds up best outdoors, and Summerset backs it with a lifetime warranty.
An island built entirely of block, metal studs, and cement board does not need one. Frame the opening to the liner size in the burner manual, not to the burner itself. Building around a power burner instead? See the Summerset Grill Liner for the Power Burner. The Summerset Grill Liner for Double Side Burners ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
FAQ
Why would a double side burner need its own insulated liner?
Side burners throw heat downward into the cabinet beneath them, not just upward at your pots. The GL-SB2 wraps that cutout in 1-inch thick double-walled #304 stainless steel so the flame chamber never transfers enough heat to ignite wood or plastic framing. If your burner station is built into anything combustible, this liner is the piece that makes it safe.
Which burners does the GL-SB2 liner actually fit?
It is fitted specifically for Summerset Double Side Burners, so the cutout dimensions match that appliance rather than a generic opening. If you are pairing a side burner with a grill in the same island, remember each appliance in a combustible enclosure needs its own correctly sized liner.
My island is concrete block – do I still need this liner?
A fully masonry or steel-framed burner station does not require insulation, since there is nothing combustible for heat to reach. The GL-SB2 exists for wood, plastic, or composite construction. Many builders still like the tidy stainless sleeve it gives the opening, but for genuinely noncombustible islands it is optional rather than mandatory.
When does the liner go in during installation?
Set the GL-SB2 into the finished cutout first, then drop the double side burner into the liner. Treat it like a sleeve: liner in the opening, appliance in the liner, gas connection last. Getting that sequence right means you never have to pull a plumbed burner back out after the countertops are set.
What is the liner made of?
Weather-resistant #304 stainless steel, the same premium grade Summerset uses on its top-line grills. The GL-SB2 panels are double-walled at 1 inch thick, and that twin-wall construction is what creates the insulating barrier between the burner box and your island framing.
How much upkeep does an insulated liner need?
Almost none. The GL-SB2 has no moving parts – wipe the visible stainless edge down whenever you clean the burner itself, and the #304 steel shrugs off rain and humidity on its own. It is designed to sit inside the island untouched for the life of the outdoor kitchen.
Is the liner covered by a warranty?
Yes. The GL-SB2 carries Summerset’s Gold Standard Lifetime Warranty, the same industry-leading coverage as their grills. For a part that gets built permanently into your island, lifetime coverage means you will never be cutting counters open to replace it on your own dime.
