Passive Heat Kit Installation Instructions
Leave this manual with party responsible for use
and operation.
CAUTION! Risk of Cuts, Abrasions or Flying Debris.
Wear protective gloves and safety glasses during instal-
lation. Sheet metal edges are sharp.
DANGER
HOT GLASS WILL
CAUSE BURNS.
DO NOT TOUCH GLASS
UNTIL COOLED.
NEVER ALLOW CHILDREN
TO TOUCH GLASS.
A barrier designed to reduce the risk of
burns from the hot viewing glass is provided
with this appliance and must be installed for
the protection of children and other at-risk
individuals.
CAUTION! Do not install damaged components.
If any parts are missing or damaged, contact your dealer before
starting installation. DO NOT install a damaged kit.
Introduction
The Passive Heat (PH-LINEAR) Heat Management Sys-
tem conveys warm air from the replace into the same room
through either one front discharge slot, two side discharge
heat registers or an open top discharge.
Installation of the Passive Heat kit must be done in con-
junction with the appliance installation. Installation of this
kit MUST be performed by a qualied service technician.
WARNING! Risk of Fire! DO NOT install the Passive
Heat (PH-LINEAR) Heat Management System with mod-
els that are not approved. Overheating will occur.
The Passive Heat Trim Kit is also available for installation
with the Front Discharge Passive Heat systems and must
be purchased separately. Contact your dealer to order
the appropriate kit: PH-FRTTRIM-32, PH-FRTTRIM-36
or PH-FRTTRIM-48.
The Passive Heat Trim kit is required with the side dis-
charge Passive Heat system and must be purchased sepa-
rately. Contact your dealer to order the PH-SIDETRIM kit.
Follow instructions included with the trim kit to complete
installation of the Passive Heat system.
The Passive Heat kit is tested and safe when installed in
accordance with this installation manual. It is your respon-
sibility to read all instructions before starting installation
and to follow these instructions carefully during installation.
The Passive Heat kit is carefully engineered and must
be installed only as specied. If you modify it or any of
its components you will void the warranty, and you may
possibly cause a re hazard. Installation must be done
according to applicable local, state, provincial, and/or
national codes.

Preparation
Plan the location of the appliance.
Determine whether front, open top or side discharge is
to be installed and follow instructions for the appropriate
application.
CAUTION! Risk of Burns!
• The replace should be turned o and cooled before
kit is installed.
• Shut o gas supply.

Power Vent Option
If an optional power vent will be installed in conjunction
with the Passive Heat Kit (PH-LINEAR), Hearth & Home
Technologies recommends the PVLP-SLP power vent
option. If the application does not allow for the PVLP-SLP
to be used, the PVI-SLP-B may be used. The PVI-SLP-B
must be mounted outside the chase due to the higher noise
level created.
The Passive Heat Kit is not compatible with a Smart-
Wall™ TV Kit , GFK-160A, GFK-240 or other fan.
For AU models, PVLP-SLP-AU is approved to be used in
conjunction with the Passive Heat Kit.

Clearances
Ensure all clearances are maintained.
• Maintain minimum distance from top of appliance
opening to the room ceiling. Refer to the gures in the
Framing section of this instruction.
• An open space, or “cavity,” is allowed up to three inches
above the top of the passive heat discharge opening. A
chase ceiling is required when the open space “cavity”
exceeds three inches above the discharge opening.
Construct the false ceiling from material such as metal,
drywall or plywood.
WARNING! Risk of Fire! Maintain clearances to
combustibles as specied.

to when installing a sprinkler head near a passive heat
discharge opening.
* If the distance from the top of the passive heat front
discharge opening to the ceiling is 36 in. (914 mm) or
greater, then there is no 36 in. (914 mm) clearance
requirement. This is for a ceiling sprinkler head
installation only.
Note: When installing a sprinkler head near a heat
discharge opening, it is recommended to use
a sprinkler head with an Extra High sprinkler
activation temperature rating.
• When installing a sprinkler head exterior of the chase,
maintain the following clearances to discharge openings
(convection slots, passive heat registers, heat zone
registers, etc.): 36 in. (914 mm) top, 18 in. (457 mm)
sides and 6 in. (152 mm) bottom.
• DO NOT install a sprinkler head inside a chase that is
set up for passive heat.

CAUTION! Risk of Cuts, Abrasions or Flying Debris.
Wear protective gloves and safety glasses during instal-
lation. Sheet metal edges are sharp.
1. Remove rear stando󰀨s and discard. See Figure 7.
2. Remove both top knockouts from outer wrap as
shown in Figure 7. Discard knockout piece and
ensure no other material or debris is blocking the hole
created by removing the knockout.
3. Center adapter over opening with the solid portion
facing the front of the appliance. Attach both adapters
to appliance by installing three screws per adapter.
See Figure 8.
Note: If installing an additional Heat Management
System, refer to the instructions included with the kit for
further installation instructions.

Passive Heat Template - Front and Side
Discharge
Install the passive heat templates to prevent nishing
material from being installed over passive heat discharge
openings. Use two templates for front discharge and four
templates for side discharge.
1. Hand bend templates as shown in Figure 9.
2. Place one template into the top left corner of the
discharge opening as shown in Figure 10. Align the
outside edge of the framing with the notch in the
template as shown in Figure 11. Attach to framing
using wood screws.
3. Place the second template into the bottom right
corner and attach using the same method as in
Step 2. If installing templates on framing for a side
discharge kit, repeat the process for the additional
two templates on the other side discharge opening.
4. Once the wall nishing material has been installed,
remove the templates and discard. After the
templates have been removed, the trim kit, register,
or other nishing options may be installed.

Painting
Side Discharge:
If desired nishing includes painting of the side discharge
register covers, Hearth & Home Technologies recom-
mends using high temperature paint with a minimum of
300 °F (149 °C) continuous exposure rating.
Finishing
1. Apply wall sheathing material, such as drywall up to
1/2 in. (13mm) thick up to the edge of the discharge
opening.
WARNING! Risk of Overheating! DO NOT apply wall
sheathing past the edge of discharge opening or nishing
templates. Remove nishing templates before appliance
operation. Overheating of appliance and combustible
materials will occur.
Front Discharge and Open Top Discharge:
The location of the Passive Heat discharge opening could
allow for venting and other construction materials to be
visible. It is recommended to paint the vent pipe, restop,
and other visible construction materials, as shown in Fig-
ure 12 using a high temperature paint with a minimum
of 300 °F (149 °C) continuous exposure rating. Hearth
& Home Technologies recommends using black touch
up paint (part number TUP-GBK-12) available from your
Hearth & Home Technologies dealer.
2. Facing Material with Front Trim Kit (PH-FRTTRIM)
1 Inch Thick or Less: When using Non-Combustible fac-
ing material in this thickness range, the Overlap Fit meth-
od may be used. Place facing materials up to the edge of
the discharge opening and install trim kit as instructed.
Facing must not interfere with the air ow through the trim
kit.
Greater than 1 Inch: Non-Combustible facing material
in this thickness range must use the Inside Fit method.
Place facing materials up to ½ in. (13mm) away from the
edge of the trim kit to allow for proper removal of the vent
cover. Install trim kit as instructed. Consult the appliance
Installation Manual to determine maximum facing mate-
rial thickness.
3. Facing Material with Side Discharge (PH-SIDETRIM)
1 Inch Thick or Less: When using Non-Combustible
facing material in this thickness range, the Overlap Fit
method may be used. Place facing materials up to the
edge of the discharge opening and install register covers
as instructed. Facing must not interfere with the air ow
through the trim kit.
Greater than 1 Inch: Non-Combustible facing material
in this thickness range must use the Inside Fit method.
Place facing materials up to the edge of the register cov-
ers. Install register covers as instructed. Consult the units
Installation Manual to determine maximum facing mate-
rial thickness.
4. Install trim kit (PH-FRTTRIM or PH-SIDETRIM) as in-
structed.
Side Discharge: The PH-SIDETRIM kit is required to
complete installation.
Front Discharge: The PH-FRTTRIM kit is an optional
nishing method. Other standard nishing methods may
be used as well.
