Norcold 442 - Ventilation Requirements; Certified Vent Kits and Dimensions

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
g
is re
q
uired in an R.V. refri
g
erator installa-
tion to remove the products of combustion, to isolate
the livin
g
space of the vehicle from the combustion
s
y
stem of the refri
g
erator, to remove the excess heat
from the
g
enerator area of the refri
g
erator’s coolin
g
s
y
stem, and to remove the heat that is extracted
from the refri
g
erator cabinet.
Certified installation re
q
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
g
throu
g
h the roof or throu
g
h an up-
per side wall vent. Whether roof or side wall exhaust
ventin
g
, the specified vent kit must be installed as
directed b
y
this manual. To insure ade
q
uate refri
g
-
erator performance, a continuous air flow is re
q
uired
across the refri
g
erator’s coolin
g
s
y
stem.
The air passa
g
e from the intake vent to the refri
g
era-
tor coils and from the refri
g
erator coils throu
g
h the
exhaust vent
must be unobstructed
.

for Vent Kits 2, 3, and 4
The vents for these refri
g
erators are certified b
y
A.G.A. and CGA and must be installed as directed
b
y
this manual
without modification
.
Any deviation
or substitution:
* Can result in carbon monoxide levels in the livin
g
space of the vehicle.
* Will void the a
g
encies’ certification.
* Will void the refri
g
erator warrant
y
.
* Will effect refri
g
erator performance.
The intake vent
(
lower
)
also serves as a access
(
service entrance
)
door. The bottom of the intake
vent openin
g
must be flush with the surface on which
the refri
g
erator is mounted. This confi
g
uration allows
an
y
leakin
g
propane to ventilate to the outside.
A.G.A. And CGA certification permits installin
g
the
refri
g
erator with zero
(
0
)
inches minimum clearance
between the refri
g
erator and an
y
ad
j
acent walls. This
certification does not specif
y
an
y
maximum clear-
ance. However, to insure ade
q
uate air flow across
the coolin
g
s
y
stem, the clearance must be mini-
mized. The combination of the two vents and the
minimum clearances provide the necessar
y
air flow
throu
g
h the creation of a natural draft, or "chimne
y
effect" across the coolin
g
s
y
stem.
