VENTILATION REQUIREMENTS
WARNING: Carbon Monoxide can cause
nausea, fainting, or death. Inadequate ven-
tilation or partial blockage of the refrigera-
tor’s flue can result in increased carbon
monoxide emissions when operating in the
gas mode. To prevent the emission of lev-
els of carbon monoxide, installation must
assure complete isolation of the living
space of the R.V. from the refrigerator’s
combustion system. Follow Norcold’s Ven-
tilation and Installation recommendations
explicity.
Ventin
is re
uired in an R.V. refri
erator installa-
tion to remove the products of combustion, to isolate
the livin
space of the vehicle from the combustion
s
stem of the refri
erator, to remove the excess heat
from the
enerator area of the refri
erator’s coolin
s
stem, and to remove the heat that is extracted
from the refri
erator cabinet.
Certified installation re
uires that one intake
lower
and one exhaust
upper
be used. For the models
6052, 6053, 652, and 653, the installer has the op-
tion of exhaustin
throu
h the roof or throu
h an up-
per side wall vent. Whether roof or side wall exhaust
ventin
, the specified vent kit must be installed as
directed b
this manual. To insure ade
uate refri
-
erator performance, a continuous air flow is re
uired
across the refri
erator’s coolin
s
stem.
The air passa
e from the intake vent to the refri
era-
tor coils and from the refri
erator coils throu
h the
exhaust vent
must be unobstructed
.

The vents for these refri
erators are certified b
A.G.A. and CGA and must be installed as directed
b
this manual
without modification
.
Any deviation
or substitution:
* Can result in carbon monoxide levels in the livin
space of the vehicle.
* Will void the a
encies’ certification.
* Will void the refri
erator warrant
.
* Will effect refri
erator performance.
The intake vent
lower
also serves as a access
service entrance
door. The bottom of the intake
vent openin
must be flush with the surface on which
the refri
erator is mounted. This confi
uration allows
an
leakin
propane to ventilate to the outside.
A.G.A. And CGA certification permits installin
the
refri
erator with zero
0
inches minimum clearance
between the refri
erator and an
ad
acent walls. This
certification does not specif
an
maximum clear-
ance. However, to insure ade
uate air flow across
the coolin
s
stem, the clearance must be mini-
mized. The combination of the two vents and the
minimum clearances provide the necessar
air flow
throu
h the creation of a natural draft, or "chimne
effect" across the coolin
s
stem.
