Customer questions about this product

My business is at a high elevation; does this change anything when I order gas cooking equipment?

Many gas equipment manufacturers need to make adjustments to the equipment so it operates correctly at elevations over 2,000 feet. Sometimes we can special order from the manufacturer and have your cooking equipment delivered ready-to-go, but in cases where your unit is in stock and waiting to ship, you’ll need to have a qualified service technician come to your location and alter your unit at the time of installation so that it is compatible with a higher elevation. Contact our Special Orders team prior to placing your order, and we will let you know what will work best for the equipment you are planning to purchase.

What is the standard procedure for Alto-Shaam’s Factory Authorization install process?

To ensure Alto-Shaam’s factory authorized installation and guarantee proper function, please review the Factory Authorized Installation Program form in the resources section.

Why should I buy a water filter along with this product?

Whether you purchase the suggested water filter through this product page or acquire your compatible water filter elsewhere, be sure to consult the equipment's manual and warranty to understand the importance of correct water filter usage. Using poor quality feed water may void your equipment's warranty. Therefore, it’s important that your water be filtered to the highest quality.

Alto-Shaam CTP20-20G N208-240/1 Details

Cook a wide variety of food with the perfect cooking method using the Alto-Shaam CTP20-20G Combitherm Proformance natural gas boiler-free roll-in 40 pan combi oven! This combi oven features steam and convection cooking modes to accommodate nearly any food, while the combination setting lets you thoroughly cook food much faster than steam or convection alone. And thanks to its roll-in design, you can cook large quantities of your most popular foods using half-size sheet pans or full-size food pans in compatible carts.

To give you the best cooking performance possible, this combi oven is made according to Alto-Shaam's CT Proformance standards. The intuitive PROtouch touch-screen controls make it easy for you to adjust cooking conditions in your oven for up to 40 full size food pans filled with meats, vegetables, and more. The crystal clear readout can display messages in a variety of languages for clarity, while the on-board memory can store and organize hundreds of customizable recipes. A removable core temperature probe accurately relays the interior temperature, and the three power modes help conserve energy during your off hours. A moister injection feature helps you keep a fine sheen and curst on baked goods, and for long-term cooking, the Delta-T feature lets you cook at lower temperatures for roasts. And thanks to its CombiClean PLUS automated cleaning system, you can be sure this oven will stay clean and sanitary.

A PROrinse retractable hand shower gives you manual control over water and moisture, and the built-in SafeVent system automatically disperses built-up steam at the end of a cooking cycle. Built-in LED lighting illuminates the interior at all times, and to help keep your oven sanitary, the door has a self-draining drip tray for grease and run-off.

This combi oven's exterior is made entirely of stainless steel to ensure long-lasting durability, and the CoolTouch3 triple pane window on the door gives you the full view of your food while keeping the interior properly insulated. The Zero Clearance system maximizes your floor space while protecting sensitive temperature components and controls, and with its adjustable stainless steel legs, you can be sure this unit is reliably stable. A 208-240V, 1 phase electrical connection is required for operation.
