The LG CBGJ3023S is a premium 30-inch gas cooktop featuring five sealed burners with a powerful 20,000 BTU UltraHeat burner. For fabricators working with granite, quartz, marble, or solid surface countertops, precise cutout dimensions are critical to ensure proper fit and professional installation. This template provides manufacturer-verified specifications for creating accurate cutouts in natural stone and engineered materials.
Installation Overview
The LG CBGJ3023S requires a cutout opening of 28.5 inches wide by 19.625 inches deep with a 0.5-inch corner radius. The cooktop itself measures 30 inches wide by 21 inches deep with an overall height of 3.75 inches. Total weight is 45 pounds. The unit features continuous cast-iron grates that provide a stable cooking surface across all five burners. Installation requires standard 120V electrical connection for the electronic ignition and a gas supply line. The UltraHeat burner delivers 20,000 BTU for rapid boiling, while precise simmer burners provide low-heat control. Auto reignition safety feature prevents gas leakage by automatically relighting burners if flames extinguish.
CNC Cutting Notes
When programming your CNC router or water jet for the CBGJ3023S cutout, critical tolerances must be maintained. The 28.5-inch width and 19.625-inch depth dimensions allow for proper support while preventing gaps. Corner radius of 0.5 inches prevents stress concentration in brittle materials like granite or quartz. For granite and natural stone, use diamond-tipped bits and maintain feed rates appropriate for material hardness. Quartz and engineered stone require similar tooling but may cut faster. Always create the cutout slightly undersized and test-fit before final sizing. Support the cutout piece from below during the final pass to prevent cracking or dropping. Edge polishing is essential after cutting - use progressive grits from 50 to 3000 for a professional finish. The LG CBGJ3023S has a flat bottom rim that seats directly on the countertop, so ensure the cut edge is smooth and level around the entire perimeter.
Material Compatibility
This template is suitable for all common countertop materials including granite, marble, quartzite, quartz composite, solid surface (Corian), concrete, and laminate. Granite fabricators will appreciate the standard rectangular cutout with minimal corner radius, which reduces cutting time compared to complex curved cutouts. The 0.5-inch corner radius is large enough to prevent crack initiation in natural stone while maintaining a clean aesthetic. For quartz countertops like Caesarstone, Silestone, or Cambria, the cutout dimensions work perfectly with standard fabrication practices. Solid surface materials can be cut with standard woodworking tools, though the same dimensional accuracy applies. Always verify material thickness meets the cooktop installation requirements - most installations work with standard 3cm (1.25-inch) granite or 2cm quartz with build-up.
Where to Buy
The LG CBGJ3023S gas cooktop is available through major appliance retailers including Home Depot, Lowes, Best Buy, and specialized appliance dealers like AJ Madison, Abt Electronics, and Designer Appliances. Professional fabricators can direct customers to these retailers or provide appliance sourcing as part of a complete kitchen installation package. MSRP typically ranges from $800-$1,200 depending on retailer and promotional periods. Many retailers offer delivery and installation services, though professional countertop fabricators often coordinate the complete installation including cooktop placement and gas line connection through licensed contractors.
