KOMFORT ZONE KIT
#KZK-045
For use with the Bellingham-44
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.
English and French installation manuals are available through your

1.5 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-410-6 UL181 Class 0 Air Duct piping to connect the plenum(s)
to the unit.
Hussong Mfg. Co., Inc. requires pipes to be listed as UL181 Class 0 Air
Duct to connect the plenum(s) to the unit.
• Maximum vent run: 20' (6m)

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 normal replace
operation.
• Please follow local building codes to determine what
temperature setting is relevant for your installation.

14 INSTALLATION Hussong Mfg. Co., Inc. • Kozy Heat Fireplaces Komfort Zone Kit #KZK-045 R.1
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 a bae clip with (2) screws in the front center, and
(2) screws right behind the upper edge of the replace opening.
Recycle this panel as it is no longer needed.
2. Remove (2) 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 into the rough frame opening while
maintaining minimum clearances to combustibles as listed (see
previous pages). Fix the plenum to the framing, using nails or
screws 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 (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-410-6 kit or UL-181
Class 0 approved air duct. If you are mounting the plenum
between 10' to 20' above the replace, 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-045DT discharge trim to the plenum, after the
wall nish is completed, using (2) screws if using the #KZK-045
plenum. Finishing material must not block opening and should
run evenly along plenum opening. The #KZK-045DT discharge
trim is optional depending on nishing material choice.
10. Continue with replace installation.

Pour utiliser avec le foyer au gaz à évacuation
directe Bellingham 44 nº BHM-44
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.
