Combined with five sealed gas burners and a spacious 4.5 cubic foot convection oven, the COS-EPGR304 provides the cooking performance serious home cooks need wrapped in sophisticated styling that makes your kitchen look intentionally designed.
Why Black Porcelain Cooktops Stand Out
Black porcelain cooktops represent a departure from traditional stainless steel cooking surfaces, offering distinctive aesthetic and practical benefits that make them increasingly popular in contemporary kitchens.
The glossy black surface creates dramatic visual impact that serves as a focal point in your kitchen design. The deep, rich color adds sophistication and modern appeal that works particularly well in kitchens featuring clean lines and contemporary styling.
Stain resistance of porcelain enamel surpasses many other cooktop materials. The non-porous surface doesn’t absorb spills or stains, keeping the cooktop looking clean and new even with daily cooking. Food residue and grease wipe away easily without leaving permanent marks.
Scratch resistance provides long-term durability that maintains the cooktop’s appearance over years of use. While no surface is completely scratch-proof, porcelain enamel resists scratching better than many alternatives when used with appropriate cookware and cleaning tools.
Heat distribution characteristics of porcelain-coated surfaces help diffuse heat evenly across the cooktop, contributing to consistent cooking results. The material’s thermal properties work well with gas burners to create predictable heating patterns.
Easy cleaning becomes possible with smooth porcelain surfaces that don’t have texture or grain to trap food particles. Most spills wipe away with damp cloths, while tougher residue responds well to standard cooktop cleaners designed for enamel surfaces.
The timeless appeal of black cooktops means they won’t look dated as kitchen trends evolve. Black works with virtually any cabinet color, countertop material, or design style, providing flexibility that helps your range remain attractive through future kitchen updates.

The knob indicator lights on the COS-EPGR304 represent a thoughtful design feature that combines safety, convenience, and visual appeal in one elegant solution. These illuminated knobs set this range apart from standard models while providing practical benefits.
Visual confirmation shows at a glance which burners are currently active. The illuminated knobs make it immediately obvious which controls are turned on, preventing accidentally leaving burners running after cooking ends.
Safety benefits come from the clear indication of active burners, particularly valuable in busy kitchens where multiple people cook or when distractions occur during meal preparation. The lights help prevent accidents and wasted gas from forgotten burners.
Modern aesthetic appeal comes from the sleek look of illuminated controls that add sophisticated visual interest to the range’s design. The lights create an upscale appearance that suggests attention to detail and quality engineering.
Low-light visibility makes the controls easy to locate and operate even in dimly lit kitchens. Evening cooking becomes more convenient when you can easily see which knobs control which burners without turning on bright overhead lights.
The mirror-finished knobs reflect and enhance the indicator lights while providing attractive hardware that complements the black porcelain cooktop and stainless steel body beautifully.
Five Sealed Gas Burners for Cooking Versatility
The COS-EPGR304 features five sealed gas burners arranged to provide maximum cooking flexibility while maintaining efficient workflow patterns. This configuration handles complex meal preparation that requires multiple dishes cooking simultaneously at different temperatures.
Sealed burner design contains spills within the burner area, preventing liquids from dripping into the range interior where they create cleaning challenges and potential odors. This containment makes cleanup significantly easier while protecting internal components.
Varied BTU outputs across the five burners accommodate different cooking tasks effectively. High-output burners excel at boiling water quickly or searing proteins at high heat, while lower-output burners provide gentle heat for delicate sauces or maintaining warm temperatures.
The five-burner layout provides more cooking capacity than standard four-burner ranges, allowing you to prepare complete meals with multiple components without waiting for burner availability. This extra capacity becomes particularly valuable during holiday cooking or dinner parties.
Even burner spacing prevents crowding and allows use of multiple large pots and pans simultaneously. You can position cookware without interference, making cooking more efficient and less frustrating than ranges with tight burner arrangements.
Instant heat control comes from gas burners that respond immediately to adjustments. Turn the knob and flames adjust instantly, giving you precise temperature control that makes cooking techniques like sautéing and stir-frying much easier to execute successfully.
4.5 Cubic Foot Convection Oven Capacity
The generous 4.5 cubic foot oven provides ample space for family meals and entertaining while incorporating convection technology that improves cooking results across various dishes.
Convection cooking uses a fan to circulate heated air throughout the oven cavity, creating more even temperatures and faster cooking times. This technology eliminates hot spots and produces more consistent results than conventional ovens.
The spacious interior accommodates large roasts, multiple casserole dishes, or several sheet pans of cookies. Holiday meals and dinner parties become more manageable when you have adequate oven space to work with multiple dishes.
Four oven functions provide cooking options that optimize performance for different types of food. Each function adjusts heating patterns and fan operation to create ideal conditions for specific cooking tasks.
Multiple rack positions allow flexible arrangement of dishes based on size and cooking requirements. The convection system maintains consistent temperatures throughout the oven, making all rack positions equally effective for most cooking tasks.
Interior oven lighting lets you monitor cooking progress without opening the door and losing heat. This visibility helps you check doneness and make timing decisions without interrupting the cooking process.
304-Grade Stainless Steel Construction
