Installation planning
- Cut-out: 23-1/4" W x 20-3/4" D x 8" H. Overall size: 25" W x 25-3/4" D x 21" H.
- Build it into a non-combustible island (cement board on steel studs is Summerset's recommendation). For a combustible island, fit the grill liner.
- Clearances: at least 2" from a non-combustible wall or backsplash at the sides and rear; at least 10" from a protected combustible wall.
- Ventilation openings in the island must give a combined free area of at least 40 sq. in.
- Natural gas models use the supplied regulator set to 4" water column; propane needs a regulator set to 11" water column. Have a licensed gas fitter make the connection.
- Outdoors only. Summerset counts a space as outdoors if it has no roof and walls on up to three sides; a roof and no more than two walls; or a roof and three walls with at least 30% of the perimeter permanently open (sliding doors, windows and screens don't count). Never use it in a garage, building, shed or breezeway.
- Overhead construction: keep at least 5 feet between the countertop and anything overhead, and never install under unprotected combustible overhead construction. Under any overhead cover, the cooking area needs an exhaust hood larger than the cooking area, moving at least 1,000 CFM, and the hood and overhead materials must be non-combustible.
- Place the island vents for your gas: natural gas rises, so vents go near the top of the enclosure; propane sinks, so vents go near the floor (both, if the fuel might change). Openings sit 1" to 5" from the countertop or floor, ideally on opposite sides, with 6" kept clear in front of each vent outside the island and 2" inside.
- Propane: it runs on a standard 20 lb tank with a Type 1 valve (not included), about 12" across and 18" tall. Never fill a tank past 80%, never keep a spare tank under or near the appliance, and store tanks outdoors, upright. Summerset does not recommend connecting to a home bulk propane tank.
- Keep the gas line as short as possible: pressure drops with distance and with every elbow or tee. Running a grill and side burner from one line takes a 3/8" tee fitting (not supplied). Summerset recommends a licensed gas technician for all gas lines.
- Level it in every direction. An appliance out of level burns erratically and heats unevenly.
- Leak-test every connection with 1 part soap to 3 parts water before first use and after every tank change. Growing bubbles mean a leak: turn off the gas and fix it before use.
- Keep it away from construction dust (stone dust, stucco, lime) and pool chemicals, which can permanently discolor stainless steel. Note visible box damage on the delivery receipt; report hidden damage to the carrier within 5 days and keep the carton.
- Wind: the grill draws air in at the front and vents out the back of the hood, so don't grill with wind blowing into the rear. A wind guard behind the grill needs 3" of clearance to non-combustible or 18" to combustible materials. Summerset excludes wind damage (melted knobs or igniter wires, a discolored control panel) from the warranty.
Use and care
Preheat with all burners on high and the hood closed for 10 to 15 minutes (about 450°F on the hood gauge), then turn off the burners you won't cook on; the grates can run up to 200° hotter than the gauge reads. After each cook, burn off debris and brush the grates. Once a month: run it on high for 15 minutes with the hood closed, let it cool for about 90 minutes, soak the grates in warm water with Simple Green, scrape the drip tray, brush the flame tamers and burners, clear any clogged burner holes, and vacuum the basin. Check the burner and venturi tubes for insect nests, which can start a fire under the grill. Wash the stainless steel with warm soapy water along the grain, rinse, and dry with a microfiber towel. Never cover it while damp, and use a rust inhibitor near pools or salt air. Heat discoloration after the first use is normal.
