Introduction

The Passive Heat (PH-LINEAR) Heat Management Sys-
tem conveys warm air from the fireplace 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 qualified service technician.
WARNING! Risk of Fire! DO NOT install the Passive
Heat (PH-LINEAR) Heat Management System with mod-
els 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-32, PH-FRTTRIM-36
or PH-FRTTRIM-48.
The Passive Heat Trim kit is required with the side dis-
charge Passive Heat system and must be purchased sepa-
rately. Contact your dealer to order the PH-SIDETRIM kit.

accordance with this installation manual. It is your respon-
sibility to read all instructions before starting installation
