Allow a minimum of 1½ inches of clearance from the sides and back of the heater and a minimum of 3 inches from the top of the heater. The factory supplied wall mounting bracket, located on the heating unit's shipping pallet, will provide the correct wall-to-back-of-heater clearance. If the heater is a 120V plug-in model with a security base, the base will provide the proper wall-to-back-of-heater clearance. The base is packaged inside the shipping box on the back side of the heater.
If enclosing the room heating unit in a wooden cabinet or recessing the room heating unit into a wall, allow 2 inches clearance on sides and 4 inches on top. Do not enclose or otherwise obstruct access to the heater's front panel and grill. Objects such as curtains, furniture, or bed covers must be kept a minimum of 4 inches from all room heating unit surfaces and 15 inches from the grill.
NOTE: If there is less than a 12 inch clearance on the right side of the room heating unit, Steffes recommends installing a remote wall mounted room temperature sensor.
