Gas Connection
The refri
g
erators are desi
g
ned to operate on pro-
pane
g
as at a suppl
y
pressure of 11 inches water
column. A pressure re
g
ulator is re
q
uired between the
refri
g
erator and the main
g
as tank.
Do not connect
the refrigerator directly to the main propane tank
without a pressure regulator.
Use suppl
y
pipin
g
and fittin
g
s that compl
y
with local,
state, and national codes

overnin

pe and size.
These components should also compl
y
with NFPA
501C. Flexible metal connectors must compl
y
with
the current CAN 1-6.10 Standard. To prevent
g
as
pressure loss to the refri
g
erator, the propane should
be supplies b

a 3/8 inch diameter copper pipin

.

Route the
g
as suppl
y
pipin
g
to limit vibration and
abrasion. The
g
as suppl
y
pipin
g
should enter the re-
fri
g
erator enclosure near the
g
as connection at the
rear of the refri
g
erator. The hole throu
g
h which the
g
as pipin
g
enters should be of sufficient size
(
ap-
proximatel
y
1/2 inch diameter
)
to provide ade
q
uate
clearance for the pipin
g
. Once the
g
as pipin
g
is in
place, appl
y
a sealant around the pipin
g
at its point
of entr
y
to minimize abrasion and vibration, and to
serve as a barrier to external moisture.
CAUTION: Use two wrenches when ma-
nipulating the gas inlet fitting. Failure to
use two wrenches can over stress the pip-
ing and create gas leaks.
The
g
as suppl
y
is connected to the refri
g
erator at
the inlet to the manual
g
as valve located at the bot-
tom rear of the refri
g
erator. Access to this area is
obtained throu
g
h the vehicle’s lower vent door. Care
must be taken when connectin
g
the
g
as pipin
g
to the
refri
g
erator to insure the fittin
g
s are secure.
120 Volt AC Connection
WARNING: The refrigerators are designed
to operate on a 120 volt, 60 Hertz
grounded AC circuit. The refrigerator’s AC
power cord is equipped with a three-prong
grounding plug which must mate with a
three-prong grounded receptacle to protect
against possible electrical shock hazards.
Operating the refrigerator without proper
ground can cause property damage, se-
vere personal injury, or death. It is the in-
staller’s responsibility and obligation to
provide a properly grounded electrical cir-
cuit to the refrigerator accordance with lo-
cal codes, or in the absence of local
codes, the National Electrical Code,
ANSI/NFPA 70. Do not cut or remove the
round grounding prong from the refrigera-
tor’s AC power cord. Do not use a two
prong adapter or an extension cord.
The free len
g
th of the refri
g
erator’s AC power cord
is 24 inches. It is recommended that the three-pron
g
g
rounded receptacle be located to the left side of the
refri
g
erator
(
viewed from rear
)
and approximatel
y
12
inches from the floor
(
see Fi
g
ure 9 above
)
. The AC
power cord must be routed so as not to contact the
refri
g
erator’s burner, flue pipe, or an
y
other compo-
nent which could dama
g
e the cord insulation.
12 Volt DC Connection
A 12 volt DC suppl
y
is re
q
uired to maintain the
flame i

nition circuit in the
