Hestan 30 Gas Cooktop
Description
IMPORTANT MODEL VERIFICATION NOTICE: The model designation "GCT305" does not appear in Hestan's current or historical product catalog. Based on extensive research, Hestan's actual 30-inch gas cooktop model is KGC30, featuring a verified cutout dimension of 29 inches by 19.625 inches (19-5/8"). This discrepancy is critical for fabricators—the listed template dimensions of 28.875" x 19.75" do not match manufacturer specifications and could result in costly rework. Hestan specializes in premium professional-grade cooking appliances with precise engineering tolerances that demand exact cutout accuracy. Before machining any countertop, fabricators must verify the actual model number on the appliance nameplate and cross-reference with Hestan's official installation guides. The KGC30 features five sealed burners with heavy-duty cast-iron continuous grates and requires specific clearances for gas line connections and ventilation. This template should be updated to reflect verified KGC30 specifications before use in production environments.

Installation Overview
Gas cooktop installations present unique challenges compared to electric units, particularly regarding combustion air supply and fuel line routing. The Hestan KGC30 (not GCT305) requires a precise 29 x 19-5/8-inch cutout with corners radiused to prevent stress concentration. Unlike electric cooktops that rely on compression gaskets, gas units need slight clearance for thermal expansion—the cast-iron grates and brass burner assemblies undergo significant dimensional change during heating cycles. Fabricators must coordinate with licensed gas fitters to ensure adequate access for the 1/2-inch NPT gas supply connection, typically located at the right-rear quadrant of the unit. Countertop materials adjacent to gas burners experience different thermal loading than electric installations; the open flame from a 20,000 BTU power burner can reach surface temperatures exceeding 800°F during extended use. Recommend 6-inch minimum setback from combustible backsplashes and heat-resistant edge treatments for materials like marble or limestone that may discolor from sustained thermal exposure. Always verify local code requirements for gas appliance clearances before finalizing cutout positioning.
CNC Cutting Notes
When programming CNC toolpaths for gas cooktop cutouts, prioritize dimensional accuracy over speed—gas appliances have tighter installation tolerances than electric units due to safety seal requirements. For the verified KGC30 cutout (29" x 19-5/8"), use a conservative three-pass approach: rough cut at 70% depth, semifinish at 90%, and final pass at full thickness with feed rate reduced to 60 IPM. The 0.5-inch corner radius must be executed with controlled tangential entry to avoid overcut conditions that compromise gasket compression. Gas cooktops generate minimal vertical load compared to electric units, but the cast-iron grate system requires rigid support—ensure your cutout doesn't cantilever more than 3 inches beyond the nearest cabinet support member. For materials prone to thermal shock (granite, marble), consider routing a slight relief channel on the underside perimeter; this allows the stone to expand without cracking when burners operate at maximum output. Diamond tooling is essential for engineered quartz—the high resin content in proximity to gas flames demands perfect edge finishing to prevent delamination from heat exposure. Never use climb milling on gas cooktop cutouts; conventional milling provides superior edge compression and minimizes the microcracking that can propagate from thermal cycling.
Material Compatibility
Gas cooktop installations favor materials with superior thermal stability and heat resistance. Granite remains the gold standard for gas cooking applications—its crystalline structure handles thermal gradients exceptionally well, and the natural stone provides excellent heat dissipation away from burner zones. Engineered quartz from Caesarstone or Cambria requires careful consideration; while structurally sound for the cutout itself, the polymer resins can discolor with sustained heat exposure above 300°F. Specify heat-resistant edge treatments or maintain 8-inch minimum spacing between burner grates and countertop surface. Solid surface materials are generally unsuitable for high-BTU gas cooktops—Corian and similar acrylics can deform at temperatures exceeding 350°F, which is easily reached during stockpot boiling or wok cooking. Ultra-compact surfaces like Dekton excel in gas cooktop applications; their sintered composition withstands direct flame contact without degradation. Soapstone provides natural heat resistance and actually benefits from thermal exposure, developing a richer patina over time. Concrete countertops work well if properly sealed with high-temperature epoxy; standard acrylic sealers will fail under sustained heat. For any material selection, discuss cooking habits with the homeowner—serious home chefs using multiple burners simultaneously generate far more heat than casual users.
Where to Buy
Hestan cooktops occupy the premium segment of the appliance market, typically available through specialized retailers rather than big-box stores. The verified KGC30 model ranges from $2,200 to $2,800 depending on finish options (stainless steel versus custom color selections). Authorized Hestan dealers include high-end kitchen design showrooms, specialty appliance retailers like AJ Madison, and commercial equipment suppliers who serve the residential market. Regional distributors such as Ferguson Enterprises stock Hestan products with professional installation support. Fabricators should note that Hestan offers extensive customization—backsplash colors, knob finishes, and grate configurations can be specified to match kitchen design themes. These customizations don't affect cutout dimensions but may extend lead times to 6-8 weeks for delivery. When coordinating with contractors or designers, always request the actual appliance model number rather than generic "30-inch Hestan gas cooktop" descriptions. Some retailers bundle Hestan cooktops with matching ventilation hoods at discounted package pricing. For commercial fabrication shops, establishing direct relationships with Hestan's technical support team (available through their professional products division) provides access to engineering drawings and installation specifications not readily available through consumer channels.
