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.

KOMFORT ZONE KIT

#KZK-1510

For use with replaces #CLW-72 and #BHM-52

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.

The tubing that connects the plenum to the replace must be UL181 Class 0 approved air duct.

If you are mounting the plenum above the replace 10’ (3m) or less, use (1) #KZK-610 kit.

If you are mounting the plenum above the replace between 10’ (3m) to 20’ (6m)

you will need (2) #KZK-610 kit and (1) #KZK-CPL6 coupler kit.

1.5 Air Duct Pipe Run

IMPORTANT: The air duct pipe cannot run horizontally without a

vertical rise.

IMPORTANT: The 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.

IMPORTANT: The specied clearance around the air duct pipes must

be maintained for each unit.

CLW-72: 1-1/2" (38mm) around the air duct pipes. See Figure 1.7 on

page 6.

BHM-52: 1/2" (12mm) around the air duct pipes. See Figure 1.8 on

page 7.

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.

3.3 Hearth and Mantel Clearances

The following drawings show the hearth and mantel clearances

allowed for the BHM-52 and CLW-72 with no surround or optional

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

minimum distance needed between the hearth and mantel to allow

for proper servicing clearances.

3.3.1 CLW-72 Finishing Guidelines

for Optional Surrounds

• Figure 3.8 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.
