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
of
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
as suppl
pipin
to the manual
shut-off valve located at the top of the refri
erator.
Connect the 12 volt DC suppl
to the terminal block also
located at the top of the refri
erator. Connect the AC
power cord to the receptacle. Place the "O" rin
sonto
the ends of both flexible pipes. Bend the flexible pipes
so the
clear the top of the enclosure. Connect the
pipin
as follows:
Exhaust Pipe - This pipe is insulated and connects to
the flue tube of the coolin
unit. Route
and connect to the bottom openin
of
the vent terminal housin
.
Intake Pipe - This pipe is
not
insulated and connects to
the burner cover. Route and connect to the
top openin
of the vent terminal housin
.
Secure both flexible pipes to vent terminal housin
with lockin
washer and screw. Slide refri
erator com-
pletel
into enclosure.
Propane System
Testing of the Vehicle’s Gas Supply Piping
When installation is complete, the propane
as
suppl
pipin
must be inspected and tested for leaks
from the refri
erator to the main
as suppl
tank. Use
a leak detection solution.
Do not test for leaks with an
open flame.
If compressed air is used for leak testin
, the pressure
must not exceed 1/2 psi
14 inches water column
.
The appliance and its individual shutoff valve must be
disconnected from the
as suppl
pipin
s
stem durin
an
pressure testin
of that s
stem at test pressure in
excess of 1/2 psi
14 inches water column
.
The appliance must be isolated from the
as suppl
pipin
s
stem b
closin
its manual shutoff valve durin
an
pressure testin
of the
as suppl
pipin
s
stem at
test pressure less than or e
ual to 1/2 psi
14 inches
water column
.
Check the
as pressure to the refri
erator without
other
as appliances operatin
. The pressure should
not exceed 11 inches water column. With other appli-
ances operatin
the pressure should not be less than
10.5 inches water column.
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
s
stem. The correct burner
flame is dependent upon correct input
as pressure
and the burner and burner orifice bein
clean. The
propane
as pipin
and the suppl
pressure must be
inspected and tested at least twice a
ear. All inspec-
tions and tests must be performed b
the propane
as
supplier or a
ualified service a
enc
.
Avisual check of the burner flame should be made
re
ularl
. The burner flame can be observed throu
h
the air inlet
rille as shown in Fi
ure 5.
As illustrated in Fi
ure 6, the flame should be sharp
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
coolin
unit’s flue tube. Also observe the position of the
flame; it must be centered under the flue tube without
touchin
the inner wall of the tube.
