1. Introduction
The Side Discharge Ducted Passive Heat (PHSI-MCE)
System conveys warm air from the replace into the same
room through a front discharge slot connected to the ap-
pliance heat management knock outs with the provided
ex ducting. Installation of the Ducted Passive Heat kit
must be done in conjunction with the appliance installation.
Installation of this kit MUST be performed by a qualied
service technician.
WARNING! Risk of Fire! DO NOT install the Ducted
Passive Heat (PHSI-MCE) Heat Management System
with models that are not approved. Overheating will occur.
The Side Discharge Passive Heat Kit is not approved for
use on 60 or 72 sized appliances.
The Ducted 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 Ducted Passive Heat kit is carefully engineered and
must be installed only as specied. 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.

5. Installation Instructions
PHSI-MCE kits must be installed on the two inside
passive heat knockouts unless a HEAT-OUT-GAS or
HEAT-ZONE-GAS will also be installed. Outer knockouts
may be used for additional heat management systems
(HEAT-OUT-GAS, HEAT-ZONE-GAS). Do not remove
the outer knockouts if they will not be used.
Only one passive heat option may be installed on a single
appliance. Passive Heat kits without ducts may not be
used in conjunction with the Ducted Passive Heat kit.
1. Remove the two inner heat management knockouts
from the top of the appliance by dislodging them with
a hammer and then using a screwdriver to remove
from the holes. See Figure 5.1 and Figure 5.2. Install
collars over the openings using hurricane screws
provided in the kit.
WARNING! Risk of Overheating! Both passive heat
side discharge assemblies included with kit MUST be
installed and operational. Overheating of appliance and
combustible materials will occur.
Install Assemblies and Flexible Duct - Side Discharge
CAUTION! Risk of Cuts, Abrasions or Flying Debris.
Wear protective gloves and safety glasses during
installation. Sheet metal edges are sharp.
WARNING! Risk of Fire! Remove ONLY the knockouts
required for the specic heat management kits being
installed. Appliance and combustible materials will
overheat.
REMOVE ONLY TWO INNER KNOCKOUTS
Figure 5.1 Remove Knockouts
3. Set a collar in each of the holes where the knockouts
were removed. See Figure 5.3.
4. Remove the screws from the heat shield as shown in
Figure 5.7. Quantity and location of screws will vary
between models.

2. Place the side discharge assembly into the wall with
the arrows on the nailing tabs facing upward.
See Figure 5.13. The height of the side discharge
assembly is denoted by the notches in the nailing tabs
that are to be lined up with the edge of the header
closest to the side discharge assembly. Ensure
the side discharge assembly is centered in the wall.
Mount side discharge assemblies into wall using
drywall framing screws or nails.
3. Repeat Step 2 to install the second side discharge
assembly on the other side of the appliance.

4. Cut ex venting to appropriate length to run from
top of the appliance to the back side of the side dis-
charge assembly ensuring there are not any kinks.
Be sure that the ex venting is not so tight as to col-
lapse where attached to the side discharge assembly
and restrict airow. Refer to Section 3 and Figure 3.1
regarding length and pitch requirements.
