Introduction
The Passive Heat (PH-FRT-LINEAR, PH-SIDE-LINEAR)
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 conjunction with the appliance installation. Installation of this
kit MUST be performed by a qualied service technician.
WARNING! Risk of Fire! DO NOT install the Passive
Heat (PH-FRT-LINEAR or PH-SIDE-LINEAR) 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: PHTRIM-32LINEAR, PHTRIM-36LINEAR
or PHTRIM-42LINEAR.
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 responsibility 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 specied. 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-FRT-LINEAR or PH-SIDELINEAR), 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 SmartWall™ 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
Clearance - Sprinkler to Passive Heat
WARNING! Risk of Fire! Maintain clearances to
combustibles as specied.
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.
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 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.
