by Norcold without modification.
The clearance from the refri g erator's left side ( facin g
the front of the refri g erator ) to the vehicle's 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. Refer to Figures 3 and 4 for
maximum clearances from refrigerator cabinet to vehi-
cle exterior wall.
The wall thickness the vent terminal housin g will
accommodate is .030" minimum to 1.250" maximum.
Fi g ure 2 illustrates the confi g uration of the openin 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.
