READ ALL THESE STEPS BEFORE STARTING
INSTALLATION. LEAVE THESE INSTRUCTIONS
WITH THE APPLIANCE.
This kit must be installed by a qualied installer,
service agency, or gas supplier at the time of the
heater installation. These instructions must be used
in conjunction with the installation and operation
manual provided with the appliance. Please read
the appliance owner’s manual completely before
performing any procedures in these instructions.
INSTALLER: Leave this manual with the appliance.
CONSUMER: Retain this manual for future reference.
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 replace
opening for locating televisions, artwork, etc.

1.1 Air Duct Pipe 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-410-6 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.
• Maximum vent run: 20' (6m)
WHEN INSTALLING AIR DUCT PIPE MAINTAIN A MINIMUM 4" VERTICAL RISE FOR EVERY 12" HORIZONTAL RUN

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.

4.0 INSTALLATION
All contents in this kit are required and must be installed.
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 (2) cover plates on top of the appliance (4 screws each).
2. Remove the convection bae from the appliance. The bae is
secured by a bae clip with (2) screws in the front center, and (2)
screws right behind the upper edge of the replace opening. See
FIGURE 4.2. Recycle this panel as it is no longer needed.
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 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 (4) plenum take o collars to all (4)
take o collars on the replace. If you are mounting the plenum
10' or less above the replace, use (1) #KZK-410-6 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-410-6 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-038DT discharge trim to the plenum after the
wall nish is completed using (2) screws. Finishing material must
not block and should run evenly along plenum opening. The
#KZK-038DT discharge trim is optional depending on nishing
material choice.
10. Continue with replace installation.

Ce kit doit être installé par un centre de service ou
un installateur qualié, ou par le fournisseur de gaz,
au moment d’installer l’appareil de chauage. Ces
instructions doivent être utilisées conjointement

Ce kit optionnel de conduits d’air de convection
redistribue 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 adja-
cents, ou même vers la pièce adjacente. Cela permet
de réduire beaucoup la température des murs au-des-
sus du foyer, pour pouvoir y installer une télévision,
des objets d’art ou autres.
