1. Introduction
The Ducted Passive Heat (PHFR-MCE-XX) System conveys
warm air from the replace into the same room through
a front discharge slot connected to the appliance 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 (PHFR-MCE-XX) Heat Management Sys-
tem with models that are not approved. Overheating will
occur.
See Table 1. Follow instructions included with the trim kit
to complete installation of the Passive Heat system.
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 Passive Heat kit is carefully engineered and must be
installed only as specied. If you modify it or any of its com-
ponents 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.

3. Preparation
Plan the location of the appliance and the warm air duct
runs. See Table 3.1.
WARNING! Risk of Fire!
• DO NOT fold/kink/pinch/obstruct 6 inch exible ducts.
Appliance could overheat.
• Maintain 1 inch clearance around all sides of exible duct.
*Size 60 And 72 appliance models must use all 4 heat
management knock outs unless the addition of 1 alternate
heat management system is used (HEAT-OUT-GAS, HEAT-
ZONE-GAS) in conjuction with the ducted passive heat.
If alternate heat management systems are used with the
Ducted Passive Heat Kit (PHFR-MCE-XX), they must use
an outside heat management knockout location on the far
left or right of the appliance.

above, 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.
REMOVE ALL 4 KNOCKOUTS FOR 60 AND 72 INCH MODELS
REMOVE ONLY TWO INNER KNOCKOUTS
FOR 36 AND 48 INCH MODELS
2. Remove the insulation plug from each knockout.
Discard. See Figure 5.2.
3. Set an inner ue in each of the holes where the
knockouts were removed. See Figure 5.3.

CAUTION! Risk of Cuts, Abrasions or Flying Debris.
Wear protective gloves and safety glasses during
installation. Sheet metal edges are sharp.
5. Installation Instructions
PHFR-MCE-36 and PHFR-MCE-48 kits must be
installed on the two inside passive heat knockouts. Outer
knockouts may be used for additional heat management
systems (HEAT-OUT-GAS, HEAT-ZONE-GAS). Do not
remove the outer knockouts if unused.
PHFR-MCE-60 and PHFR-MCE-72 kits must be installed
on all four passive heat knockouts unless a HEAT-OUT-
GAS or HEAT-ZONE-GAS will be installed.
One additional heat management system may be used
in conjunction with the Ducted Passive Heat kit. If an
additional heat management system (HEAT-OUT-GAS,
HEAT-ZONE-GAS) is installed, that system must use one
of the outer (left or right) knockouts. The other three must
be maintained for connection to the Ducted Passive Heat
kit.
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.
Note: For 36 and 48 sized models the kit will include two
collars. The two inside knockout locations are the only
ones used.
WARNING! Risk of Fire! Remove ONLY the knockouts
required for the specic heat management kits being
installed. Appliance and combustible materials will
overheat.

9. Install collars over the openings using hurricane
screws provided in the kit. PHFR-MCE-36 and PHFR-
MCE-48 kits must be installed on the two inside pas-
sive heat knockouts. Outer knockouts may be used
for alternate heat management systems. See Figure
5.10 and 5.11.
PHFR-MCE-60 and PHFR-MCE-72 kits must be in-
stalled on all four passive heat knockouts. One ad-
ditional heat management system may be used in
conjunction with the Ducted Passive Heat kit. If an
additional heat management system (HEAT-OUT-
GAS, HEAT-ZONE-GAS) is installed, that system
must use one of the outer (left or right) knockouts
while the other three must be maintained for connec-
tion to the Ducted Passive Heat kit.
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 Pas-
sive Heat kit.
