Summerset Side Burner Installation (Single and Double)
Summerset single and double side burners are built-in accessories that drop into a dedicated cutout beside the main grill. Install is about 40 minutes once the cutout is framed and gas is stubbed. Both the Single Side Burner and Double Side Burners manuals use the same install envelope — the double just has two cutout widths.

Step by step
Verify cutout width per model
Single Side Burner cutout is approximately 12" W x 19" D x 8" H. Double Side Burner cutout is approximately 24" W x 19" D x 8" H. Confirm against the current Single or Double Side Burner manual PDF at summersetgrills.com before cutting.
Frame ventilation below the burner
Side burner cavities need the same below-cavity ventilation as the main grill — vented panel or open cavity. Heat from the burner builds in a sealed cavity and discolors the stainless over time.
Rough-in gas
The side burner shares the main grill's gas line in most installs. Confirm total simultaneous BTU load — single side burner adds ~15,000 BTU, double adds ~30,000 BTU to whatever the grill draws. A 1/2" line is often adequate; a 3/4" line is needed for TRL Pro 40 + double side burner running together.
Drop the burner into the cutout
The side burner seats flush on the island top with its rolled edge. One person can usually manage the lift. Verify level front-to-back.
Connect gas, leak-test, first-fire
Pipe thread sealant on NPT. Soapy water on every union. Open the valve, ignite each burner, confirm blue flame.
Common mistakes
- Undersized gas line for simultaneous operation. A 1/2" line that works for the grill alone may starve when the side burner runs at the same time. Verify total BTU and line sizing BEFORE the cutout.
- Installing too close to combustible countertop material. Side burners need the same non-combustible surround as the main grill. Butcher block, laminate, or wood directly adjacent to a side burner is a fire hazard and voids the warranty.
Hands-on tips
- If you plan to use the side burner for wok cooking, size up to the double even if you think single is enough. Wok heat loves BTU and the double's combined output is closer to the output of a dedicated wok burner.
- Keep a windguard on hand. Open-flame side burners are more wind-sensitive than main burners, and the windguard pays for itself in propane and cook times.
Questions people ask
Can I use the side burner as a sear burner?
Not as effectively as the TRL Pro's built-in dual-position infrared sear. The side burner is an open-flame burner designed for pots and pans, not direct-sear cooking.
Is the side burner warranty the same as the main grill?
The Gold Standard Lifetime Warranty applies to the side burner's main burner tube. Other parts (regulator, valves) carry standard warranty terms. The warranty document shipped with the side burner has specifics.
