Introduction

The Passive Heat (PH-FRT-LINEAR, PH-SIDE-LINEAR)
Heat Management System conveys warm air from the
fireplace into the same room through either one front dis-
charge 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 qualified service technician.
WARNING! Risk of Fire! DO NOT install the Passive
Heat (PH-FRT-LINEAR or PH-SIDE-LINEAR) Heat Man-
agement 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 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.
