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.

Installation
The
heater
cutout
should
have
a
minimal
size
of
16
1
/
2
(h)
x
12
3
/
4
(w).
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.
