General Information

This refrigerator is not intended to be operated as a

Free-Standing refrigerator (i.e. the products of combus-

tion must be completely isolated from the living area)

or installed in such a way as to conflict with these

installation instructions. Unapproved installations could

result in safety risks or performance problems.

The model 3163 is desi

ned for built-in installation and

operates on propane

as, 120 volts AC, or 12 volts DC.

The propane

as mode of operation is that of a sealed

combustion unit. A sealed combustion installation util-

izes a sin

le fresh vent-air intake/exhaust assembl

suppl

fresh air to the burner and to remove the prod-

ucts of combustion. This insures the products of com-

bustion are isolated from the livin

area of the vehicle.

The vent-air intake/exhaust assembl

is routed throu

the vehicle’s outside wall and is connected to the

refri

erator’s burner assembl

and exhaust flue tube b

flexible pipin

. The vent-air intake/exhaust assembl

used for this installation has been certified for this

refri

erator and

must not

be modified.

Direct Vent Requirements

Interior Ventilation

The refri

erator’s coolin

stem re

uires a continual

air flow to maintain proper refri

eration. An inlet and

exhaust vent is re

uired to insure ade

uate air flow.

The refri

erator is e

uipped with an inlet vent located

at the bottom front of the refri

erator. The installer is

uired to provide the exhaust vent. The exhaust vent

must have a cross sectional area of 30 s

uare inches

minimum. The exhaust vent is to be installed above the

top surface of the refri

erator so as not to trap hot air

enerated b

the coolin

unit. The refri

erator is

uipped with a DC ventilation fan to assist the air flow

across the refri

erator’s coolin

stem while operatin

the refri

erator in the Gas mode.

Ventilation Fan

A thermostat controlled mechanical fan is used to

move air across the refri

erator’s coolin

stem. The

thermostat is calibrated to activate the fan whenever

the vehicle’s interior temperature reaches 85 de

rees

or hi

her.

When leavin

the vehicle unattended, it is advisable

to leave windows or roof exhaust vents open to main-

tain the vehicle’s interior temperature below 85 de-

rees. This will allow the refri

erator to operate

efficientl

, minimize fan operation, and limit current

draw from the batter

Installing the Vent-Air Intake/Exhaust Assy

Improper location and installation can cause injury or

property damage. This refrigerator and it’s vents are

design certified by the American Gas Association and

the Canadian Gas Association. Any deviation or sub-

stitution will void the agencies’ certifications and the

Norcold warranty. Refer to this manual for proper in-

structions. Install the refrigerator and vents as directed

by Norcold without modification.

The clearance from the refri

erator’s left side

(

facin

the front of the refri

erator

)

to the vehicle’s exterior wall

is important. This is the area in which the inlet and outlet

flexible pipin

will be connected to the vent terminal

housin

durin

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

will

accommodate is .030" minimum to 1.250" maximum.

ure 2 illustrates the confi

uration of the openin

for

the vent terminal housin

Do not make the opening in

the vehicle wall larger than required.

The clearance

should be enou

h for the terminal housin

to pass

throu

h the openin

. If the openin

is too lar

e, the

outer

asket will not cover the vent housin

openin

It is imperative that the wall openin

for the vent

terminal housin

not be too low. The flexible pipin

(

inlet and outlet pipes

)

must rise from the refri

erator to

the terminal housin

. There are two specific vent-air

intake assembl

kits available to accommodate most

installations.

Insulating the Flexible Exhaust Piping

The flexible exhaust pipe must be insulated prior to

installation into the vent terminal housin

. The flexible

exhaust pipe connects to the flue tube of the refri

era-

tor’s coolin

unit and routes to the bottom openin

the vent terminal housin

. Use the non-combustible

insulation material supplied with the vent-air intake/ex-

haust kit.

Do not insulate the Air Intake pipe.

Installing Refrigerator into the Enclosure

Set the refri

erator into the enclosure and slide it back

enou

h to connect the

Gas Burner Flame

The

as operation of the refri

erator is controlled b

the correct burner flame which supplies the heat input

to the refri

erator’s coolin

stem. The correct burner

flame is dependent upon correct input

as pressure

and the burner and burner orifice bein

clean. The

propane

blue with a stable burnin

appearance. If there is a

constant

ellow component observed or if the flame

appears erratic and unstable, perform the followin

inspection. Check the

as suppl

pressure to insure the

pressure is between 10.5" W.C. min. - 11" W.C. max..

Inspect the Air Intake pipe between the burner and the

vent terminal housin

for obstructions. If the

as suppl

pressure is within specifications, and the Air Intake pipe

is clear of obstructions, clean the burner, orifice, and

Diagnosing Cooling Problems

Read this information before attemptin

to perform

service on this refri

erator. Understand the service

procedures before performin

the service.

Always apply the safety precautions on page 1 and the

precautions listed below. Failure to follow these safety

precautions can result in substantial property damage,

severe personal injury, or death.

•

Never bend, drop, drill, weld, or hammer the

coolin

unit. Doin

so can cause the coolin

unit

to rupture, releasin

chemicals under hi

h pres-

sure. Contact with these chemicals ma

cause

severe burns to the e

es or skin.

•

Never attempt to repair or rechar

e the coolin

unit. A defective coolin

unit must be replaced.

Diagnostic Procedures

1. Make sure the coolin

problem occurs while op-

eratin

the refri

erator in each mode of opera-

tion. If not, the coolin

problem is not the coolin

unit. Refer to Trouble Shootin

sections to deter-

mine cause for insufficient coolin

on identified

mode of operation.

2. Make sure the interior ventin

is not obstructed

and is providin

air circulation across the coolin

unit’s absorber coils and condenser fins.

3. Make sure the 12 VDC ventilation fan is func-

tional. The fan will operate whenever the vehi-

cle’s interior temperature reaches 85

or hi

her.

See pictorial and trouble shootin

uide on

es 17 & 18.

4. An off-level situation, if the infraction is mar

inal,

will allow the refri

erator to continue to operate

at a reduced level of coolin

until the refri

erator

is leveled. Greater off-level situations will stop the

refri

erant circulation and cease coolin

. Normal

vehicle levelin

to provide comfort for the occu-

pants is within the refri

erator’s operatin

limits.

The refri

erator’s operatin

limits are 3 de

rees

off-level front-to-back and 6 de

rees off-level

side-to-side. Operatin

the refri

erator outside of

these operatin

limits for an extended time will

cause irreparable dama

e to the coolin

unit.

5. Check the input volta

es and

as pressure to

insure correct heat input and volta

e limits.

The specifications are as follows:

a. 120 VAC - 108 VAC min. to 132 VAC max.

b. 12 VDC - 11.5 VDC min. to 15.4 VDC max.

c. Gas - 10.5" W.C. min. to 11" W.C.

Correct input volta

es and propane

as suppl

are critical for the coolin

unit to function properl

6. Check the area of the coolin

unit for refri

erant

leaks. The smell of ammonia is a positive si

n of

a refri

erant leak.

When an ammonia smell is

detected, the cooling unit must be replaced.

An-

other si

n of a refri

erant leak is the appearance

of a

ellow powder in the vicinit

of the coolin

unit.

When this powder is observed, the cooling

unit must be replaced.

7. Check the absorber coils; the bottom coil will be

warm and the top coil will be cooler.

If the coils

are cold and the cooling units flue enclosure is

too hot to touch, there is a blockage in the cooling

unit and the cooling unit must be replaced.
