KOMFORT ZONE KIT

#KZK-1510A

For use with the #BHM-44 and #CLW-50 (Starting

Serial Number: 19 501780 50)

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

local dealer. Visit our website www.kozyheat.com.

1.1 Kit Contents

ALL kit contents must be installed.

• (2) 15" plenum kit: #KZK-1510A

• (2) air grilles

• (8) 6" collars - (4) to attach to the bottom of the plenum; (4) to

attach to the unit where the cover plates are removed.

(1) KZK-410-6 is used for a 10' vent run. If you are mounting the

plenum above the replace 10' (3m) or less, use (1) #KZK-410-6 kit.

KZK-CPL6 is (6) 6" couplers that connect (2) KZK-410-6. You will only

need (4) 6" couplers for installation. If you are mounting the plenum

above the replace between 10' to 20', you will need (2) KZK-410-6 kit

and (1) #KZK-CPL6 coupler kit.

1.2.1 BHM-44 Requirements

For ease of installation, the header heat shield may be removed.

The stand-o assembly still must be installed. To install stand-o

assembly,

1. Locate the stand-o assembly and header heat shield on top of

the replace, as shipped.

2. Discard header heat shield.

3. Attach the stand-o assembly pieces as shown below and secure

with (4) screws.

1.3 Suggested Congurations

When installing the #KZK-1510A, take in consideration the replace

venting and the plenum tube conguration.

The (2) plenums and the (2) air grilles in this kit are required and both

must be installed.

1.5 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)

2.0 FRAMING AND CLEARANCES

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.

3.2 Combustible Finish

NOTE: If you desire to run nishing material up to edge of the discharge

opening, see drawing below. Finishing material must not block the air

discharge grille 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 AND the convection

bae is removed when using these combustible clearances.

3.2.1 Drywall Finish

IMPORTANT: Additional 1" (25mm) combustible trim on top of

existing materials is NOT allowed inside the side shelf enclosure

(Section 2.3 Shelf Requirements on page 12.)

1" (25mm) combustible material goes on top of any required non-

combustible material required on the replace as shown in Figures

3.1 and 3.2 on page 10 for CLW-50 and Figure 3.3 on page 11 for

3.3 Hearth and Mantel Clearances

The following drawings show the hearth and mantel clearances

allowed for the CLW-50 and BHM-44 with no surround or optional

surrounds installed (if applicable). Follow the drawings for the

minimum distance needed between the hearth and mantel when

installing an optional surround to allow for proper servicing

clearances.

3.3.1 CLW-50 Finishing Guidelines

for Optional Surrounds

• Figure 3.7 shows where to end nishing materials, when

measuring from the nishing edge, to allow installation of any

optional surround. Most nishing 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.
