KOMFORT ZONE KIT
#KZK-1510
For use with replaces #CLW-72 and #BHM-52
This optional convection duct kit redistributes the
warm air ow away from the replace opening to
a more desirable location using natural convection
without the use of a fan. The warm air ow may be
relocated to a position higher up the wall, out the
sidewalls, or even to an adjacent room. The result
is much cooler wall temperatures above the re-
place opening for locating televisions, artwork, etc.
The use of this kit will permit lower mantel clear-
ances to be used. These lower mantel clear-
ances must be only used when the KZK Duct
system is installed.
