2.4 Safety Barrier Informaon

WARNING: A barrier designed to reduce the risk of

burns from the hot viewing glass is provided with this

appliance and shall be installed for the protecon of

children and other at-risk individuals.

If the barrier becomes damaged, the barrier shall be

replaced with Hussong Mfg.’s barriers for this appliance.

Please refer to Secon 5.3 Safety Barrier Installaons for

mounng and installaon opons.

IMPORTANT: Consider the height of hearth nish material

when building a replace plaorm. Proper installaon of safe-

ty barriers require the boom of the replace to be level with

nished hearth.

NOTE: The nishing trim kit is highly recommended as it en-

sures proper tment of safety screen barrier along with an

edge to stop nishing material against. This ensures proper

venlaon air ow and accessibility for replace servicing. See

Secon 5.2.

Safety Barriers Approved for All Design Opons

(Standard or Kozy Zone Kit Installaons)

3.0 Framing

3.1 Appliance Placement Consideraons

Read all documentaon for your specic installaon and

design opons prior to appliance installaon.

WARNING: Due to high temperatures, the appliance

should be located out of trac and away from furniture

and draperies.

FIRE HAZARD: Do NOT install this appliance directly on

carpeng, vinyl, or any other combusble material other

than wood.

Note: Unless otherwise noted all clearances / images in this

manual are based o of nominal 2” x 4” framing being used.

• This appliance must be installed on a level surface ca-

pable of supporng the replace and venng. If possi-

ble, place the replace in a posion where the vent

terminates between two studs, eliminang the need

for any addional framing.

• This replace may be installed in a bedroom.

• Please be aware of the large amount of heat this re-

place will produce when determining a locaon.

3.2 Appliance Installaon Opons

This appliance oers several design opons for managing

the heat produced by this replace.

Note: When deciding on which design opon suites your

applicaon please review all secons throughout this

manual as dierent design opons have dierent framing,

facing, and nishing opons and requirements.

• Standard Installaon will be outlined in this manual in

secons marked ‘standard installaon’ and must be

followed if no design opons (Komfort Zone Kit) are to

be used. The replace chamber and ceiling minimum

height must be 80” (2032mm) for standard installa-

ons. Only the safety barriers shown in Figure 2.2 are

allowed for this installaon scenario.

• Komfort Zone Kit (KZK) oers the opon to redistribute

radiant heat through a plenum. This opon allows for

combusble facing materials above the replace, heat

reducon for a TV above the replace, and lower man-

tel clearances. See secon 4.0, Heat Management on

page 21. If installing a Komfort Zone Kit (#KZK-045), the

framing requirements may be dierent than the stand-

ard dimensions listed in this secon. Please reference

the manual included with your kit before compleng all

replace framing and other installaon consideraons.

The replace chamber and ceiling minimum height

must be 86” (2184mm) for KZK opons. Safety barriers

shown in Figure 2.2 and Figure 2.3 are allowed for in-

stallaon when using an approved Komfort Zone Kit.

Safety barriers shown in Figure 2.3 are only allowed for

use with an approved Kozy Zone Kit.

• Kozy Power Vent is a fan-powered mechanical dra

vent system (horizontal terminaons only) for use with

any of the design opons listed previously in this sec-

on (Standard or Komfort Zone Kit). Reference the

#KPV manual for all system requirements. Ulizing the

Kozy Power Vent system will not change facing and

nishing requirements or safety barrier requirements

from the Standard or Komfort Zone Kit design opons.

3.3 Floor Support and Protecon

• Floor protecon in front of the replace is not required. Com-

busble material may be used if installing a hearth extension.

Consider the thickness of the hearth extension nishing materi-

al if building a replace plaorm. The boom of the replace

must be level with nished hearth extension for proper t of a

safety barrier.

• If this appliance is to be installed directly on carpeng, le, or

other combusble material other than wood ooring, this ap-

pliance shall be installed on a metal or wood panel extending

the full width and depth of the appliance.

• If the appliance is to be installed above oor level, a solid, con-

nuous plaorm must be constructed below the appliance.

3.4 Seng the Appliance

• This secon outlines informaon on seng the appliance in the

framed opening and starng the installaon process.

• Decide on your appliance installaon opon menoned in Sec-

on 3.2 before seng the appliance. Your framing require-

ments, clearance to combusbles, and vent conguraon will

depend upon this decision.

IMPORTANT: If you are using a KZK appliance installaon opon

refer to Secon 2.4 for important safety barrier informaon and

Secon 4.0 for addional preparaon steps that must be completed

before seng the appliance in the framed opening.

General Procedure

 Frame your opening based on your selected appliance installa-

on opon. Refer to Secon 3.8 for informaon for the framed

opening of the standard installaon opon. If you are using a

KZK installaon opon refer to the KZK manual for framing.

 Lay out the path for your vent run before installing appliance.

 We recommend installing the nishing trim kit. This provides a

shadow box around the required safety barrier. Your nishing

material will bu up against the nishing trim. Refer to Secon

5.2 for installaon of nishing trim kit. If you are using the n-

ishing trim kit, this must be installed before the following steps.

 Install the nailing anges on the appliance. Refer to Secon 3.6

for assembly and installaon. The nailing anges are where you

secure your appliance to the framed opening. The framing will

be ush with the appliance when it is installed.

 Assemble and install the top stand-o assembly. Refer to Sec-

on 3.5 for more informaon on the top stand-o assembly.

This stand-o assembly provides the necessary thermal protec-

on of the header.

 Place the replace inside the framed opening and secure the

appliance into the framing. The replace will be ush with the

framing. If you use the nishing trim kit, the trim kit will sck

3.8 Wall Enclosure Rough Framing

Note: Unless otherwise noted all clearances / images in this

manual are based o of nominal 2” x 4” framing being used.

3.8.1 Rough Framing

WARNING: Provide adequate clearances around air openings

into the combuson chamber. Provide adequate clearance in

front of the replace for barrier removal, component access,

gas line installaon, service access, etc.

CAUTION: Cold air transfer area. The surround replace

chase must comply with all clearances as outlined in this

manual, and be constructed in compliance with local

building codes. Outside walls should be insulated to prevent

cold air from entering room.

Rough-in dimensions outlined in FIGURE 3.4 below are the

same for all design opons and must be followed.

• Floor protecon in front of the replace is not required.

Combusble material may be used if installing a hearth

extension. Consider the thickness of the hearth

extension nishing material if building a replace

plaorm. The hearth may be ush with the boom

nishing edge of the replace.

• The boom of the replace must be placed directly on a

wood or non-combusble surface (not linoleum or

carpet). If this appliance is to be installed directly on

carpeng, le, or other combusble material other than

wood ooring, this appliance shall be installed on a

metal or wood panel extending the full width and depth

of the appliance.

• Framing dimensions should allow for wall covering

thickness and replace facing materials.

• If masonry (oponal) is to be used, prepare the foundaon

necessary for the full masonry load. A lintel must be used

over the top of the appliance to support the added weight

of the masonry construcon above the replace.

3.8.2 Mounng a Television Above a Fireplace and

Television Recess Construcon

WARNING: All clearances to venng must be maintained.

• Mounng a television above a replace is a common

pracce. Mantel depth, ceiling heights, and wall and mantel

construcon material all aect television surface tempera-

tures. Most television manufacturers specify in their

instrucons that a television should not be installed on,

near, or above a heat source.

• If you want a Television above a replace it is highly

recommended install the replace with the KZK installaon

design opon. Refer to Secon 3.2 for more informaon on

the KZK design. Install the plenum discharge above the

locaon of a television. This will help distribute heat from

below the TV to above the TV. We also recommend the use

of a mantel to deect heat away from the television.

• Television locaon rests solely on the homeowner. It is the

home owner’s responsibility that the preferred TV

mounng and mantel design will not exceed the listed

maximum operaon temperature of their electronic goods.

• The allowed TV recess of 4-1/4” (108mm) measures from

the front of the nominal 2x4 framing to the backside of the

nishing material of the pocket.
