Installation Guidelines (continued)
Heater Wiring
Regardless of the model chosen, there are 5 wires inside the base of the heater which
must be wired correctly. Three wire contacts are required to obtain the power source.
The wiring code is the same for 120 volt units.
The heater must be provided disconnect device (switch/breaker) from the supply mains
having a contact separation in all poles that provide full disconnection with a contact
separation of at least 3 mm.
On the large in‐wall unit the black is hot, the red is neutral, and the green is ground. On
the small in‐wall unit the black is hot, the blue is neutral and the green is ground. On
both units the yellow and white wires go directly to the thermostat.
No external power supply is needed. Any attempt to attach an external power supply
will cause damage to the internal components and will result in product failure.
When connecting multiple units to a single thermostat, the units must be connected in
parallel with all yellow and all white wire leads connected to their same respective
terminals on the thermostat.
Failure to follow these guidelines will result in internal transformer failure and product
failure.
The figures below depict a typical wiring procedure using conventional 12/2 wire on a large heater.
Thermostat Wiring
Use any conventional thermostat or doorbell wire to route the thermostat to the
heater. Unless the thermostat is diode protected or voltage sensitive to DC (positive
and negative), it doesn't matter which heater thermostat wire goes to the respective
contacts on the back of thermostat.
Consult the wiring instructions that are included with the thermostat to make sure that
the low voltage thermostat being used is compatible with the 12 volt DC voltage
originating from the yellow and white thermostat wires from the heater. The
thermostat should be located at least 5 feet from the location of the in‐wall heater.

Mounting Guidelines (CZ-1000F)
CZ‐1000F Existing Construction Installation

SITE
Use the following
mounting brackets
for heater installation
in existing construction.
Use the retrofit brackets as shown. Attach the heater unit to the wall, 6 ft.
(1.8 m) or higher above the floor to the bottom of the heater unit. The higher
the better. The higher location of the heater insures that obstacles in the room
such as furniture will not encumber the circulation of the infrared heat waves
being generated from the heater. This assures even heat distribution and
prevents cold‐pockets of air.
