Introduction
The Passive Heat (PH-MR) Heat Management System
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-MR) Heat Management System with models
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-36
PH-FRTTRIM-42
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.
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.

If an optional power vent will be installed in conjunction
with the Passive Heat Kit, 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.
For AU models, PVLP-SLP-AU is approved to be used in
conjunction with the Passive Heat Kit.

Painting
Side Discharge:
If desired nishing includes a painted register cover,
Hearth & Home Technologies recommends using high
temperature paint with a minimum of 300 °F (149 °C) con-
tinuous 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.
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 acceptable to paint the vent pipe and other
construction materials 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) avail-
able from your Hearth & Home Technologies dealer.
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. See Figure 12. 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. See
Figure 12. Place facing materials up to ½ in. (13mm)
away from the edge of the trim kit to allow for proper re-
moval of the vent cover. Install trim kit as instructed. Con-
sult the appliance Installation Manual to determine maxi-
mum facing material thickness.
3. Facing Material with Side Discharge (PH-SIDETRIM)
1 Inch Thick or Less: When using Non-Combustible fac-
ing material in this thickness range, the Overlap Fit meth-
od may be used. See Figure 12. 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. See
Figure 12. Place facing materials up to the edge of the
register covers. Install register covers as instructed. See
Figure 14. Consult the appliance Installation Manual to
determine maximum facing material 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 trim kit (PH-FRTTRIM-36 or PH-
FRTTRIM-42) is an optional nishing method. Other stan-
dard nishing methods may be used as well.
