Propane System - Norcold 3163 Service Manual

Insulating the Flexible Exhaust Piping
The flexible exhaust pipe must be insulated prior to
installation into the vent terminal housin g . The flexible
exhaust pipe connects to the flue tube of the refri g era-
tor's coolin g unit and routes to the bottom openin g of
the vent terminal housin g . 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 g erator into the enclosure and slide it back
enou g h to connect the g as suppl y pipin g to the manual
shut-off valve located at the top of the refri g erator.
Connect the 12 volt DC suppl y to the terminal block also
located at the top of the refri g erator. Connect the AC
Testing of the Vehicle's Gas Supply Piping
When installation is complete, the propane g as
suppl y pipin g must be inspected and tested for leaks
from the refri g erator to the main g as suppl y tank. Use
a leak detection solution. Do not test for leaks with an
open flame.
If compressed air is used for leak testin g , the pressure
must not exceed 1/2 psi g ( 14 inches water column ) .
The appliance and its individual shutoff valve must be
disconnected from the g as suppl y pipin g s y stem durin g
an y pressure testin g of that s y stem at test pressure in
excess of 1/2 psi g ( 14 inches water column ) .
The appliance must be isolated from the g as suppl y
pipin g s y stem b y closin g its manual shutoff valve durin g
an y pressure testin g of the g as suppl y pipin g s y stem at
test pressure less than or e q ual to 1/2 psi g ( 14 inches
water column ) .
Check the g as pressure to the refri g erator without
other g as appliances operatin g . The pressure should
not exceed 11 inches water column. With other appli-
ances operatin g the pressure should not be less than
10.5 inches water column.
Gas Burner Flame
The g as operation of the refri g erator is controlled b y
the correct burner flame which supplies the heat input
to the refri g erator's coolin g s y stem. The correct burner
flame is dependent upon correct input g as pressure
and the burner and burner orifice bein g clean. The
propane g as pipin g and the suppl y pressure must be
inspected and tested at least twice a y ear. All inspec-
tions and tests must be performed b y the propane g as
supplier or a q ualified service a g enc y .
A visual check of the burner flame should be made
re g ularl y . The burner flame can be observed throu g h
the air inlet g rille as shown in Fi g ure 5.
power cord to the receptacle. Place the "O" rin g s onto
the ends of both flexible pipes. Bend the flexible pipes
so the y clear the top of the enclosure. Connect the
pipin g as follows:
Exhaust Pipe - This pipe is insulated and connects to
Intake Pipe - This pipe is not insulated and connects to
Secure both flexible pipes to vent terminal housin g
with lockin g washer and screw. Slide refri g erator com-
pletel y into enclosure.

Fi g ure 5
As illustrated in Fi g ure 6, the flame should be sharp
blue with a stable burnin g appearance. If there is a
constant y ellow component observed or if the flame
appears erratic and unstable, perform the followin g
inspection. Check the g as suppl y 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 g for obstructions. If the g as suppl y
pressure is within specifications, and the Air Intake pipe
is clear of obstructions, clean the burner, orifice, and
coolin g unit's flue tube. Also observe the position of the
flame; it must be centered under the flue tube without
touchin g the inner wall of the tube.
