Island mount, Cavaliere range hoods are made out of 19 gauge stainless steel that comes in a satin finish. The range hoods are electronically controlled with multiple, pre-programmed functions and they are equipped with dimmable halogen lights. They can be vented through ducts to the outside or with a use of a recirculation kit and a set of charcoal filters, the hoods can recirculate air within the room. The standard ceiling height for installation is a maximum of 9 feet, however there are extension kits available for 10, 11, and 12 foot high ceilings. The extension kits are specific to particular types of the hoods, thus they cannot by mixed and matched freely. A potential buyer needs to pay a close attention to the model number of the range hood and the extension kit designed for it, especially while buying the extension kit separately from the range hood. The pictures of the extension kits are deceivingly similar to one another, thus a mistake can be easily made. That's why it is advisable to check the model number with a technical support before a purchase is made directly on-line. The range hood models on Warehouse USA website are paired together with extension kits, so finding the right extension for the range hood on-line is a fairly easy process. In order to determine if an extension is needed, the distance between the cooktop and the bottom of the hood needs to be calculated and it should stay between 28" and 31" for an optimal range hood operation.
