Westlake GCO613S 39 In. Double Stack Natural Gas Convection Oven, 120,000 BTU, Double Circulating Fans, Dual Pane Glass Windows

The Westlake GCO613S Gas Convection Oven

The Westlake GCO613S is a 39 in. wide double stacked gas convection oven: two complete ovens on one footprint, each firing 60,000 BTU/hr of natural gas for 120,000 BTU/hr in total. Each deck has its own burners, double circulating fan, thermostat, and timer, so you can run dinner rolls at one temperature up top while sheet pans of roasted chicken finish at another below. That is the difference from a single deck, where everything in the oven shares one setting. It keeps pace when a banquet for 200 and regular dinner service land on the same night. It fits a high-volume restaurant, bakery, or catering kitchen that fills two cavities most days; a kitchen that bakes a few pans a shift will be paying to heat a deck it rarely loads. The stack stands 70.7 in. tall on casters, it takes gas through a 3/4 in. NPT rear connection, it comes set up for natural gas, and it needs electrical power for the fans, timers, and lights.

120,000 BTU/hr Stainless Steel Tube Burners

Stainless steel tube burners deliver 60,000 BTU/hr per deck on natural gas, 120,000 BTU/hr for the stack, or 52,000 BTU/hr per deck on LP. Because each deck fires on its own, loading cold pans of bone-in chicken into the bottom oven does not pull heat away from the pastry baking above it. An automatic ignition system lights the burners, so your opener is not reaching in with a lighter.

Double Circulating Fan in a 25-3/8 In. Deep Cavity

Each oven has a double circulating fan that drives heated air around the load. Still heat browns the top rack and leaves the bottom pale. Moving air evens that out, which is why you can fill the racks and skip the mid-bake pan shuffle. The cavities run 25-3/8 in. deep, and the porcelainized interiors give spatter a smooth surface to wipe from instead of bare metal to bond to.

11-Position Rack Guides with Chrome Plated Racks

Heavy duty chrome plated racks sit on removable 11-position guides. Set them tight for sheet pans of cookies or spread them out for turkey breasts and deep hotel pans of baked ziti. The guides lift out, so cleaning the cavity walls at close is a wipe-down and not a reach around fixed rails.

167 °F to 563 °F Thermostat and 60-Minute Timer

Temperature adjusts from 167 °F to 563 °F. Hold cooked product warm at the low end, or roast hard at the top of the range. The 60-minute electric timer rings a bell when the batch is done, so your line cooks can stay on their stations through the rush. A cooling down function is also included.

Dual Pane Thermal Glass Windows and Door Shut-Off Switch

Dual pane thermal glass windows and an interior chamber light show you the color of the bake without opening the doors. When you do open one, a micro switch shuts that oven off completely, so no hot air is blowing at the cook reaching in. The front is stainless steel, and the sides are galvanized with robust support.

    The Westlake GCO613S Gas Convection Oven

    About Convection Ovens

    Commercial convection ovens are a standard in professional kitchens for a reason. They circulate hot air evenly throughout the oven cavity, which means faster cook times, more consistent results, and better use of every rack. Whether you're running a restaurant, a bakery, or a high-volume foodservice operation, a commercial convection oven handles everything from roasting and baking to reheating and finishing dishes.

    Common Types and Configurations

    • Gas convection ovens: Lower gas costs and quick heat recovery. Standard in high-volume kitchens.
    • Electric convection ovens: Precise temperature control and simple installation. Best for kitchens without a gas line.
    • Countertop convection ovens: Compact units for prep counters. Good for small operations or tight spaces.
    • Half size convection ovens: Built for half size sheet pans. Fit well in bakeries, cafes, and smaller kitchens.
    • Full size convection ovens: Take full size sheet pans and handle higher volume. Standard in full service kitchens.

    What to Look at Before You Buy

    • Gas or electric: Gas ovens cost less to run but require a gas line and licensed installation. Electric ovens are easier to install and offer more precise control.
    • Size: Match the oven size to your pan size and volume. Half size ovens work for lower output. Full size ovens are better for high-volume kitchens.
    • Number of racks: More racks mean more capacity. Check the rack spacing to make sure it fits your pans and menu items.
    • Temperature range: Most commercial convection ovens run between 150°F and 500°F. Make sure the range fits your menu.
    • Controls: Manual controls are simple and reliable. Digital controls allow programmable settings for consistency across staff.
    • Steam injection: Some models include humidity or steam injection, useful for bakery items that need moisture during the bake.
    • Installation: Gas units need a licensed installer and proper ventilation. Electric units require the correct voltage and amperage. Confirm your kitchen's power capacity before ordering.

    Frequently Asked Questions

    What is a commercial convection oven?

    A commercial convection oven uses a fan to circulate hot air throughout the oven cavity. This produces faster, more even cooking than a standard oven. The moving air eliminates hot spots and reduces cook times, which makes convection ovens a standard choice in restaurant, bakery, and foodservice kitchens where consistency and speed both matter.

    What type of oven do professional chefs use?

    Most professional kitchens use convection ovens as their primary workhorse oven. They're faster than conventional ovens, produce more consistent results, and work well across a wide range of menu items. Bakeries often pair convection ovens with deck ovens for items that need direct heat from a stone surface. High-volume operations sometimes use combi ovens that combine convection heat with steam.

    What is the difference between a commercial convection oven and a commercial air fryer?

    Both use circulated hot air to cook food, but they are designed for different purposes. A commercial convection oven is a full size cooking unit built for baking, roasting, and high-volume output across multiple racks. A commercial air fryer is a smaller, countertop unit designed to crisp food quickly with high heat and rapid air circulation. For most restaurant kitchens, a convection oven offers more versatility and capacity.
