GUIDELINES FOR INSTALLING A TV/ARTWORK ABOVE THE UNIT

Note: All wiring should stay free and clear of the vent system to avoid damage 

due to heat. We recommend using a metal receptacle box and BX cable (120 

volt wire protected by metal sheathing) if located directly in front of the vent 

system. Ensure wiring is secured without any sag.

ZERO CLEARANCE TO TV:

 While most consumers prefer to centrally locate 

a wall mounted TV, the “Cool-Touch Wall Technology” means that the bottom 

edge of the TV can be installed flush with the bottom edge of the ventilated 

fireplace chase opening.

The TV may be recessed into a wall as shown below.

This can only recess into the chase opening a maximum of 3-1/2 inches 

and must be a minimum of 12 inches from the fireplace lip to the first stud.

To achieve a maximum of 3-1/2" recess, the wall must be of a maximum 

of 2" as shown.
