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 shall 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-FRT, PH-SIDE) Heat Manage-
ment System conveys warm air from the replace into the
same room through either a front discharge slot or two
side discharge heat registers. Installation of the Passive
Heat kit must be done in conjunction 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-FRT or PH-SIDE) Heat Management System
with models that are not approved. Overheating will oc-
cur.
The Passive Heat Trim Kit (PHTRIM-XX) is also available
for installation with the Front Discharge Passive Heat
systems and must be purchased separately. Follow in-
structions 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.

Power Vent Option
If an optional power vent will be installed in conjunction
with the Passive Heat Kit (PH-FRT or PH-SIDE), 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.
CAUTION! Risk of Burns!
• Appliance MUST be turned o and cooled before kit is
installed.
• Shut o gas supply.
Preparation
Plan the location of the appliance.
Determine whether front or side discharge is to be installed
and follow instructions for the appropriate application.

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.
• A chase ceiling is required at the top of the passive heat
discharge opening for all installations. An open space, or
“cavity,” is not allowed above the passive heat discharge
opening. Construct the false ceiling from material such
as metal, drywall or plywood.
WARNING! Risk of Fire! Maintain clearances to com-
bustibles as specied.
NOTICE: (See Through models ONLY) If Passive Heat-
Front Discharge or Open Top Chase is the selected heat
management option, consider these recommendations:
• Locate the Passive Heat discharge opening in the larger of
the two rooms served by the See-Through model installed for
optimal comfort.
• Locate the control side of the appliance and the Passive Heat
discharge opening in the same room.

Figure 3 references the clearances that must be adhered
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 inches
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 inches top, 18 inches sides and 6
inches bottom.
• DO NOT install a sprinkler head inside a chase that is
set up for passive heat.

Framing
1. Dimensions for framing using front discharge are
shown in Figure 5 using either the trim kit or using the
clean face nishing method.
2. Figure 6 shows the framing requirements for the
PH-SIDE kit using a side discharge. Do not place
combustible objects or combustible materials on the
nished wall adjacent to the non-combustible zone
(E) on either side of the appliance.
3. Dimensions for framing using the Open Top Discharge
method of installation are shown in Figure 7 using the
clean face nishing method.
4. If discharge opening (Dimension A in Figure 7) is
three inches or greater, a piece of wire mesh with 1/2
inch x 1/2 inch opening is required to be installed on
the top of the framing above the appliance.
The wire mesh will prevent objects from falling through
the opening and onto the top of the appliance. The
wire mesh may be available at a hardware or home
improvement retailer.
The wire mesh must be fastened to the top of the
framing on the bottom side of the discharge opening.
WARNING! Risk of Fire! Wire mesh required on dis-
charge opening bottom at top of framing when discharge
opening is greater than 3 inches.
NOTICE: The location of the Passive Heat discharge
opening could allow for venting and other construction
materials to be visible. It is acceptable to paint the vent pipe
and other construction materials using a high temperature
paint with a minimum of 300 °F continuous exposure rating.
Hearth & Home Technologies recommends using black
touch up paint (part number TUP-GBK-12) available from
your Hearth & Home Technologies dealer.
