Norcold 3163 - Installing the Vent-Air Intake;Exhaust Assembly

The clearance from the refri
g
erator’s left side
(
facin
g
the front of the refri
g
erator
)
to the vehicles exterior wall
is important. This is the area in which the inlet and outlet
flexible pipin
g
will be connected to the vent terminal
housin
g
durin
g
installation. Provisions must be made
to access
g
as burner observation port for service and
for visual check of the burner flame.
Refer to Figures 3
and 4 for maximum clearances from refrigerator cabi-
net to vehicles exterior wall.
The wall thickness the vent terminal housin
g
will
accommodate is .030" minimum to 1.250" maximum.
Fi
g
ure 2 below illustrates the confi
g
uration of the open-
in
g
for the vent terminal housin
g
.
Do not make the
opening in the vehicle wall larger than required.
The
clearance should be enou
g
h for the terminal housin
g
to
pass throu
g
h the openin
g
. If the openin
g
is too lar
g
e,
the outer
g
asket will not cover the vent housin
g
openin
g
.
It is imperative that the wall openin
g
for the vent
terminal housin
g
not be too low. The flexible pipin
g
(
inlet and outlet pipes
)
must rise from the refri
g
erator to
the terminal housin
g
. There are two specific vent-air
intake assembl
y
kits available to accommodate most
installations.
Figures 3 and 4 illustrate two installations
with the maximum flexible piping lengths and the vent
terminal housing locations.
