White Glove Delivery - Available -

What is White Glove service?

Standard common carrier delivery options cover the cost of getting an item to your shipping address but our White Glove delivery service does that and more!

The White Glove agent will call to schedule a delivery appointment within a four hour window, which gives you the flexibility to work around your busy schedule and to prepare the space where your item will be placed. Upon delivery, trained professionals will unload your item from the truck, bring it into the room of choice, unpack the item and remove all packaging debris from the premises.

Please note that White Glove delivery will typically add 5 - 7 business days to your order's transit, and only includes 30 minutes of on-site time. If on-site time beyond 30 minutes is required, you may be responsible for additional fees. Additionally, this service does not include set-up of the items being delivered.

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 other cases, 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.

Designed for maximum versatility, this Cleveland Convotherm OGS-12.20 combination convection oven / steamer lets you grill, roast, steam, and even make baked goods in one, convenient unit, while its wide array of automatic features makes operation easy! This combi oven features programmable controls for cooking with hot air, convection steam, and both, while its 8 "Press & Go" cooking modes and a stored recipe library allow customizable cooking and repeatable results.

A patented, "Advanced Closed System +3" automatically controls moisture levels inside the cooking compartment based on the food, in addition to also reducing cooking times and saving energy. The Convotherm OGS-12.20 also boasts a unique "Disappearing Door" that swings open and slides back along the side, saving valuable aisle space. This unit also comes with a trolley and six 26" x 20" wire shelves to easily wheel your meals in and out of the oven. This trolley can hold up to six full size sheet pans or twenty four full size 2 1/2" deep steam table pans (sold separately).

The Cleveland OGS-20.20 combination oven-steamer is UL and UL Sanitation Listed. Made in America. It requires a 3/4" NPT gas inlet, two 3/4" GHT-F water connections, and a 2" drain connection. It also requires a 120V electrical connection and must be hard wired; it does not come with a cord and plug. Please consult the Specification Sheet for additional details and installation requirements. Choose fuel type.

See Companion Items for the ConvoClean built in automatic washing system. Because it is factory-installed, it must be ordered at the same time you order your combi oven.
