KOMFORT ZONE KIT
#KZK-072
For use with the Callaway-72 #CLW-72
Direct Vent Gas Fireplace
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.
English and French installation manuals are available through your
local dealer. Visit our website www.kozyheat.com.

1.4 Air Duct Run
IMPORTANT: The air duct pipe cannot run horizontally without a
vertical rise.
IMPORTANT: The 1/2" clearance around the air duct pipes must be
maintained.
Use #KZK-610 UL181 Class 0 Air Duct piping to connect the plenum(s)
to the unit.
Hussong Mfg. requires pipes to be listed as UL181 Class 0 Air Duct to
connect the plenum(s) to the unit.

Figure 2.1, KZK Clearance to Sprinkler
2.1 Clearance to Sprinkler
• In a situation 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 setting so it does
not activate when the room heats up from the replace being
operated normally.
• Please follow local building codes to determine what
temperature setting is relevant for your installation.

NOTE: It is not required to use the #KZK-072 discharge trim (KZK-
072DT) if desired to run nishing material up to the nishing material
stando. Finishing material must not block the opening and must be
run evenly along the plenum opening.

3.3 Hearth and Mantel Clearances
The following drawings show the hearth and mantel clearances
allowed for the CLW-72 with no surround or optional surrounds
installed. Follow the drawings and the masonry guidelines below
for the minimum distance needed between the hearth, mantel, and
sidewall to allow for proper servicing clearances.
3.3.1 Masonry Finishing Guidelines
for Optional Surrounds
• Figure 3.7 shows where to end masonry nishing materials,
when measuring from the nishing edge, to allow installation of
any optional surround. Most masonry material will not t behind
the optional surround(s) when it is installed.
• Measurement 'A' shows the space to leave on each side.
• Measurement 'B' shows the space to leave on the top and the
bottom.

4.0 INSTALLATION
The Kozy Zone Kit requires that the convection bae, located above
the rebox inside the appliance metal cabinet, to be removed to
allow the hot airow to convect upwards into the air ducts installed
on the replace.
1. Remove the convection bae from the appliance. The bae
is secured by (2) screws right behind the upper edge of the
replace opening. Recycle this panel if it is no longer needed.
2. Remove (6) cover plates on top of the appliance (4 screws each).
3. Align the take o collars to the corresponding holes on top of
the appliance. Secure with screws previously removed. Install
the take o collars to the corresponding opening(s) on the
plenum(s). Use supplied screws.
4. Frame a rough opening at the desired location. See previous
pages of this manual for allowable plenum positions and rough
frame opening sizes.
5. Install the plenum(s) into the rough frame opening maintaining
minimum clearances to combustibles as listed (see previous
pages). Fix the plenum to the framing using nails or screw
through the top mounting bracket.

NOTE: Mounting brackets are not intended to carry the weight
of the plenum and pipes. Provide support to the underside of
the plenum and ensure the plenum is level and its outlet is not
distorted.
6. Use metal strapping (all-around, not supplied) as required to
further secure the plenum to framing.
7. Attach the piping from all (6) plenum take o collars to all (6)
take o collars on the replace. If you are mounting the plenum
10' or less above the replace, use (1) #KZK-610 kit or UL-181
Class 0 approved air duct. If you are mounting the plenum
between 10' to 20' above the replace then you will need (2)
#KZK-610 kits and #KZK-CPL6 or UL-181 Class 0 approved air
duct.
8. An upward slope must be maintained in horizontal sections of
pipes for proper convection. Support horizontal sections every
24 inches.

9. Install the #KZK-072DT discharge trim to the plenum after the
wall nish is completed using (2) screws, if using the #KZK-072
plenum. Finishing material must not block and should run
evenly along plenum opening. The #KZK-072DT discharge trim is
optional depending on nishing material choice.
10. Continue with replace installation.

KIT KOMFORT ZONE
nº KZK-072
Pour utiliser avec le foyer au gaz à évacuation
directe Callaway-72 nº CLW-72
Ce kit optionnel de conduits d’air de convection re-
distribue l’air chaud du foyer vers le (ou les) lieux
de votre choix grâce à la convection naturelle,
sans besoin de ventilateur. La sortie d’air chaud
peut être dirigée plus haut sur le mur, à travers les
murs adjacents, ou même vers la pièce adjacente.
Cela permet de réduire beaucoup la température
des murs au-dessus du foyer, pour pouvoir y in-
staller une télévision, des objets d’art ou autres.
L’utilisation de ce kit permet de réduire les dé-
gagements au manteau. Cette réduction de dé-
gagements au manteau est possible seulement
lorsque ce système de conduits KZK est in-
stallé.
