Operation
The HEAT-ZONE-PRIMO PowerFlow™ Heat Management
System is powered by a thermo switch. The system will
turn on approximately 10 minutes after the appliance is
turned on. The HEAT-ZONE-PRIMO accessory is tested
and safe when installed in accordance with this installa-
tion manual. It is your responsibility to read all instructions
before starting installation and to follow these instructions
carefully during installation.
Installation of this kit MUST be performed by a qualied
service technician.
The HEAT-ZONE-PRIMO 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.
WARNING! Risk of Fire! Either the HEAT-ZONE-PRIMO
or the HEAT-OUT-PRIMO PowerFlow™ Heat Manage-
ment System must remain ON during operation of the ap-
pliance. Overheating will occur. Appliance will shut down.
Introduction
The HEAT-ZONE-PRIMO PowerFlow™ Heat Management
System conveys warm air from the replace through air
ducts to remote locations in the same room or other rooms
in the building. Two HEAT-ZONE-PRIMO’s must be installed
with the PRIMO appliance or the appliance will overheat.
Two HEAT-ZONE-PRIMO’s are included in the kit.
This appliance comes standard with patented
SafeSurfaceTM Glass which keeps the surface temperature
of the barrier glass at a safe level and will still be hot to
the touch when operated for long periods of time.
If the barrier glass is removed, the inner glass temperature
will be very hot and cause burns.
Note: A minimum clearance of 18 inches to any com-
bustible materials or combustible surfaces such as room
furnishings, furniture, curtains, etc., is required from the fan
housing air outlet. Plan for this clearance prior to installation
of the Heat-Zone-Primo kit. See Figure 6 and Figure 7.
Approvals
The exible duct used with the HEAT-ZONE-PRIMO is
manufactured and marked to the requirements of UL-181,
Class I air duct.

Note: The brackets can be rotated 180º and mounted to
the back side of the 2 x 4 if necessary. See Figure 7.
If the fan housing is installed in a 2 x 4 wall, the front of the
housing will protrude approximately 1/2 in. (13 mm) out of
the wall. See Figure 7.

Electrical Connections
Wire 110-120 VAC service from the appliance to the junction
box. See Figure 9. Use wire nuts to secure the 110-120 VAC
service wires to the hot and neutral fan wires and screw the
110-120 VAC ground wire to the fan box. See wiring diagram
in section 8 of the appliance manual.
Place rheostat assembly into appliance to the right of the
valve component tray as shown in Figure 10. Use included
one inch square hook and loop fastener included in kit to
retain the rheostat.
Unplug one of the wires that is currently supplying power to
the thermodisc from the electrical junction box. Plug one
wire from the rheostat assembly into the same location on the
junction box and the other wire from the rheostat assembly
to the wire still attached to the thermodisc. See Figure 12.
Ground the rheostat to the chassis of the appliance with the
included sheet metal screw.
Screw the duct cover to the fan box.
Screw the register adapter frame and the air register to
the fan housing.
Complete the replace installation per instructions.
Other Duct Options
Metal Oval Air Duct: Attach the round-to-oval adapter to
the HEAT-ZONE-PRIMO collar with screws. Attach the 6"
oval duct to the adapter with screws. Complete the duct
run and attach the oval duct to the fan housing. Note: 6
in. metal oval duct is NOT provided with the HEAT-ZONE-
PRIMO kit, but can be purchased from an HVAC supplier.
Metal Round And Oval Duct: A combination of 6 in.
round and 6 in. oval air duct can be used in the duct run.
