This oponal convecon duct kit redistributes the warm air ow away from the replace opening to a more desirable
locaon using natural convecon without the use of a fan. The warm air ow may be relocated to a posion higher up the
wall, out the sidewalls, or even to an adjacent room. The result is much cooler wall temperatures above the replace
opening for locang televisions, artwork, etc.

2.0 Framing and Clearances
2.1 Clearance to Sprinkler
• In a situaon where a sprinkler head is installed within the proximity to a #KZK discharge opening, the diagram below
MUST be followed.
• The distance between a sprinkler head and discharge opening cannot be less than 60" (1524mm) in length at every
point from the origin of the discharge opening. You must also verify the sprinkler head sensor is set to the proper heat
seng so it does not acvate when the room heats up from the replace being operated normally.
• Please follow local building codes to determine what temperature seng is relevant for your installaon.
