From the manual for your refrigerator:
"To ensure proper ventilation for your refrigerator, allow for a 1/2" (1.25 cm) space on each side and at the top. Allow at least 2" (5.08 cm) between back of cabinet and the wall. If your refrigerator has an ice maker, make sure you leave some extra space at the back for the water line connections.
If you are installing your refrigerator next to a fixed wall, leave 3 1/8" (8 cm) minimum on the hinge side (depending on your model) to allow for the door to swing open.
NOTE: This refrigerator is intended for use in a location where the temperature ranges from a minimum of 55°F (13°C) to a maximum of 110°F (43°C). The preferred room temperature range for optimum performance, which reduces electricity usage and provides superior cooling, is between 60°F (15°C) and 90°F(32°C). It is recommended that you do not install the refrigerator near a heat source, such as an oven or radiator.
