Introduction
The Passive Heat (PH-FRT, PH-SIDE) Heat Manage-
ment System conveys warm air from the fireplace 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 qualified 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 specified. If you modify it or any of
its components you will void the warranty, and you may
possibly cause a fire 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 off and cooled before kit is
installed.
• Shut off 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.
