Location
This appliance has a cool outer casing that allows it to 
be installed in a recessed application consisting of 
combustible materials such as wood and plaster. 
The location needs to have a level surface that allows 
the appliance to be rolled in or out of the enclosure. 
If the surface is elevated and there is not enough 
room for it to be rolled out then a base and joists may 
be used as shown. 
The appliance will have to be rolled out for 
maintenance. After installation do not place any 
permanent fixtures that would prevent pulling the 
appliance out for access. To pull the appliance 
completely out of the enclosure a minimum of 15 
inches from the front panel would be needed.
