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 would be relocated to a posion higher up the
wall. The result is much cooler wall temperatures above the replace opening for locang televisions, artwork, etc.

IMPORTANT: The air duct pipe cannot run horizontally without a vercal 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.

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.

2.2 Framing
Shown in this secon are the rough opening dimensions and
clearances for the plenum, unit installaon, and unit installa-
on with a TV recess construcon.
Rough opening framing dimensions should allow for wall cov-
ering thickness and facing materials. Please refer to Secon 3.0
for specic facing and nishing opons.
Figure 2.3 show the minimum height of plenum framing from
the base of that specic replace.

3.0 Facing and Finishing
See below for some replace specic nishing material informaon:
Nordik 36 DV
The Nordik 36 DV is supplied with a “Finishing Trim Kit”. It is highly recommended that this kit is installed and used with the
replace. The nishing trim kit provides a nishing edge for material to bu up against while providing the necessary clear-
ance for the safety screen barrier to be removed.
IMPORTANT: The B36-PSF2 and B36-FRSF2 (Figure 3.1) are ONLY approved for use when the Nordik 36 DV is installed with
the #KZK-036. The other (4) safety barriers shown in Figure 3.2 are approved in all installaon scenarios.
KZK Plenum
Secon 3.2 will provide informaon about nishing material around the KZK plenum.

IMPORTANT: When using the #B36-FRSF2 or #B36-PSF2 with the Nordik 36 DV the rope on the back of the safety barrier must be
removed before installing the safety barrier.

3.2 Finishing Requirements
3.2.1 Finishing Opons - Plenum Air Discharge
NOTE: It is not required to use the discharge trim (#KZK-036DT). You are allowed to run non-combusble nishing material
up to the air discharge opening. See Figure 3.5 for nishing opons. Finishing material must not block the opening and must
be run evenly along the plenum opening.
WARNING! RISK OF OVERHEATING AND FIRE! Ensure the KZK duct system is installed in accordance to this manual

KZK-036 15 Rev. 1 - July 2023
3.2.2 Combusble Wall Finish Requirements
• Figure 3.6 shows installaon of combusble wall nish up to 1" thick for the Nordik 36 DV. This combusble material
goes on top of any required non-combusble materials as required in Figure 3.4.
• This 1" (25mm) combusble material is able to go down to the replace nishing edge.
• See Figure 3.5 on page 14 for up to 1" (25mm) thick combusble material installaon around the KZK air discharge
trim.

3.3 Hearth and Mantel Clearances
• Figure 3.7 shows the mantel and hearth projecons for the Nordik 36 DV allowed when using this KZK-036. The image
below shows the mantel projecon starng at the top replace nishing edge.
• Combusble ooring can run underneath this appliance which would then allow an unlimited combusble hearth
projecon. The hearth projecon cannot be elevated (vercally) past the base of the replace / enclosure oor.

4.0 Fireplace Preparaon & Installaon
4.1 Nordik 36 DV
All contents in this kit are required and must be installed.
The Kozy Zone Kit requires that the convecon plates, and
insulaon blanket to be removed to allow the hot airow
to convect upwards into the air ducts installed on the re-
place.
See addional requirements and installaon informaon in
the appliance manual.
1. Remove the (11) sheet metal screws that secure the
top outer shell assembly. Pull this assembly straight up
around the exhaust stack to remove it from the appli-
ance. See the rst image in Figure 4.1.
2. Remove the (4) cover plates where each cover plate is
secured with (4) sheet metal screws. See the second
image in Figure 4.1. Discard these cover plates.
Figure 4.1 - Nordik 36 Convecon Plates and Insulaon Removal
3. Remove (3) sheet metal screws from the top of the assembly
(see close up in Figure 4.2) and (2) sheet metal screws on the
side of the assembly (one screw on each side shown in the
second image of Figure 4.1). You are now able to seperate the
two secons of the top outer shell assembly. Remove and dis-
card both the insulaon and the boom secon of the top
assembly.
4. Reinstall the top outer shell assembly on the appliance with
the previously removed (11) sheet metal screws.
5. 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.
6. Frame the rough opening of the replace and KZK plenum.
Refer to all pages of this KZK-036 manual and the Nordik 36
DV manual. See previous pages of this manual for allowable
plenum posions and rough frame opening sizes.

Figure 4.5 - Trim Installaon
Figure 4.4 - Nordik 36 Stand-O Installaon
7. Install stand-o assembly on top of the appliance. See Figure
4.4. Remove and save (4) screws securing stand-o heat
shields and stand-o brackets on top of the replace.Form
each top stand-o bracket by bending at perforaons, as
shown. Align the holes in the formed top stand-os with the
holes in the replace top. Secure with the (4) screws previ-
ously removed along with (4) screws located on top of the
replace.
8. Discard the (2) horizontal heat shields.
9. Install the plenum into the rough frame opening maintaining
minimum clearances to combusbles as listed (see previous
pages). Fix the plenum to the framing using nails or screw
through the top mounng bracket.
NOTE: Mounng 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 dis-
torted.
10. Use metal strapping (all-around, not supplied) as required to
further secure the plenum to framing.
11. Aach the piping from all (4) plenum vent collars to all (4)
replace vent collars. If you are mounng the plenum 10' or
less above the replace, use (1) #KZK-410 kit or UL-181 Class
0 approved air duct. If you are mounng the plenum be-
tween 10' to 20' above the replace then you will need (2)
#KZK-410 kits and #KZK-CPL or UL-181 Class 0 approved air
duct.
12. An upward slope must be maintained in horizontal secons
of pipes for proper convecon. Support horizontal secons
every 24 inches.
13. Install the plenum discharge trim provided with the kit using
(2) screws.
If desired, the air grille may be painted. Use high temperature
paint (250°F).
Connue with replace installaon.
IMPORTANT: The B36-PSF2 and B36-FRSF2 (Figure 3.1) are ONLY
approved for use when the Nordik 36 DV is installed with the
#KZK-036. The other (4) safety barriers shown in Figure 3.2 are
approved in all installaon scenarios.
