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

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-
