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-CERONA) Heat Management
System conveys warm air from the replace into the same
room through either one front discharge slot, two side dis-
charge 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-CERONA) Heat Management System with
models that are not approved. Overheating will occur.
Side Discharge Passive Heat systems require the use of
the Register Cover Kit (PH-SIDETRIM), which must be
purchased separately, to complete the installation. Contact
your dealer to order the kit.
Passive Heat Trim Kits are also available for installation
with the Front Discharge Passive Heat system which must
be purchased separately. Contact your dealer to order
the appropriate kit: PH-FRTTRIM-36 or PH-FRTTRIM-42.
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 appliance 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-CERONA), Hearth & Home
Technologies recommends the PVLP-SLP or PVV-SLP
power vent options. If the application does not allow for the
PVLP-SLP or PVV-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.

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.

* If the distance from the top of the passive heat front
discharge opening to the ceiling is 36 inch or greater,
then there is no 36 inch 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 inch top, 18 inch sides and 6 inch
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 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.
2. Remove both insulation plugs from insulation blanket
visible through top knockout openings. Discard
insulation plugs and ensure no other material or
debris is blocking the hole created when removing
insulation plug.
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.

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.
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.

WARNING! Risk of Overheating! Be sure the venting
does not extend past the rib on Passive Heat adapter. If
venting or insulation is blocking holes in the Passive Heat
adapter overheating of chase could occur.
• Remove cap from the Passive Heat adapter and dis-
card the cap. The venting for the Heat-Out-Gas kit will
attach directly on top of the Passive heat adapter. See
Figure 16.
• Refer to the instructions included with the HEAT-OUT-
