PH-MR

Introduction

The Passive Heat (PH-MR) Heat Management System
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-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 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.

Preparation

Determine whether front, open top or side discharge is
to be installed and follow instructions for the appropriate
application.
CAUTION! Risk of Burns!
• The fireplace should be turned off and cooled before
kit is installed.
• Shut off gas supply.
NOTICE: A mantel is required if a fan is installed. Damage
to TV could occur.
