SECTION A. INSTALLATION

1.GENERAL INSTRUCTIONS

This appliance is designed for storage of foods and
storage of frozen foods and making ice.

The refrigerators outlined herein have been design certi­fied by A.G.A. under ANSI Z21.19 Refrigerator Standard
for installation in a mobile home or recreational vehicle and
are approved by the Canadian Gas Association. The
certifications are, however, contingent on the installation
being made in accordance with the following instructions
as applicable.

In the U.S.A., the installation must conform with:

1.National Fuel Gas Code ANSI Z223.1-(latest edition)

2.Manufactured Home Construction and Safety Stan­dard, Title 24 CFR, Part 3280

3.Recreational Vehicles ANSI A119.2-(latest edition).
The unit must be electrically grounded in accordance with

the National Electric Code ANSI/NFPA 70-(latest edition)
when installed if an external alternating current electrical
source is utilized.

4.Any applicable local code.

The lower side vent is fitted with a panel which provides an
adequate access opening for ready serviceability of the
burner and control manifold of the refrigerator. This should
be centered on the back of the refrigerator.

3.CERTIFIED INSTALLATION

Certified installations require one roof vent and one lower
side vent.

For certified vent system kits, see Section B.

For further information, contact your dealer or distributor.

4.METHOD OF INSTALLATION

The method of installation is shown in FIG. 1. It is essential
that all maximum or minimum dimensions are strictly
maintained as the performance of the refrigerator is depen­dent on adequate flow of air over the rear of the refrigerator.

NOTE: The upper vent should be
centered over the condenser coil
at the back of the refrigerator.

In Canada, the installation must conform with:

1.Current CGA B 149 Gas Installation Codes

2.Current CSA Standard Z 240.4 GAS-EQUIPPED REC­REATIONAL VEHICLES AND MOBILE HOUSING

3.Any applicable local code

The unit must be electrically grounded in accordance with
the CANADIAN ELECTRICAL CODE C 22 Parts 1 and 2.

2.VENTILATION

The installation shall be made in such a manner as to
separate the combustion system from the living space of
the mobile home or recreational vehicle. Louver openings
for air supply or for venting of combustion products shall
have a minimum dimension of not less than 1/4 inch.

Proper installation requires one fresh air intake and one
upper exhaust vent. The ventilation kits shown in this
instruction manual have been certified for use with the
refrigerator model listed in the Table. For "Certified Vent
System Kits" see Section B. The ventilation kits must be
installed and used without modification. An opening toward
the outside at floor level in the refrigerator compartment
must be provided for ventilation of heavier-than-air fuel
gases. The lower vent of the recommended kits is provided
with proper size openings. The flow of combustion and
ventilation air must not be obstructed.

The refrigerator is equipped with a three-prong (grounded)
plug for protection against shock hazards, and should be
plugged directly into a properly grounded three-prong
receptacle. DO NOT cut or remove the grounding prong
from this plug. The power cord should be routed to avoid
direct contact with the burner cover, flue cover or manual
gas shutoff valve knob. The free length of the cord is two
feet and therefore recommended that the receptacle be
located to the left side of the refrigerator (viewed from the
rear) and approximately six inches from the floor (see FIG.

7). This allows easy access through the vent door.

In an absorption refrigerator system, ammonia is liquefied
in the finned condenser coil at the top of the refrigerator.
The liquid ammonia then flows into the evaporator (inside
the freezer section) and is exposed to a circulating flow of
hydrogen gas, which causes the ammonia to evaporate,
creating a cold condition in the freezer.

The tubing in the evaporator section is specifically sloped
to provide a continuous movement of liquid ammonia
downward by gravity through this section. If the refrigera­tor is operated when it is not level and the vehicle is not
moving, liquid ammonia will accumulate in sections of the
evaporator tubing. This will slow the circulation of hydro­gen and ammonia gas, or in severe cases, completely
block it, resulting in a loss of cooling.

Any time the vehicle is parked for several hours with the
refrigerator operating, the vehicle should be leveled to
prevent this loss of cooling. The vehicle needs to be
leveled only so it is comfortable to live in (no noticeable
sloping of floors or walls).

When the vehicle is moving, the leveling is not critical as
the rolling and pitching motion of the vehicle will pass to
either side of level, keeping the liquid ammonia from
accumulating in the evaporator tubing.

The GAS mode indicator lamp (C) will illuminate. After
45 seconds the burner should be ignited and operating
normally.

On the initial refrigerator start-up, it may take longer
than 45 seconds to allow air to be purged from the gas
line. If the gas does not ignite within 45 seconds, the

C. THERMOSTAT

The thermostat on the refrigerator controls both the
gas and electric operation, thereby eliminating the
necessity of resetting each time a different energy
source is employed.

After the initial start-up, the thermostat should be
moved from "COLDEST" to the desired temperature
setting, usually about mid-setting.

MODES

A. AUTO MODE

When operating in the AUTO mode, the AUTO mode
indicator lamp (B) will illuminate. The control system
will automatically select between AC and GAS opera­tion with AC having priority over GAS. Either the AC
indicator lamp (A) or the GAS indicator lamp (C) will
illuminate depending on the energy source selected
by the control system. If the control system is operat­ing with AC energy and it then becomes unavailable,
the system will automatically switch to GAS. As soon
as AC becomes available again, the control will switch
back to AC regardless of the status of GAS operation.

B. GAS MODE

When operating in the GAS mode, the AUTO mode
indicator lamp (B) will be off and the GAS mode indicator
lamp (C) will be illuminated. This mode provides LP gas
operation only. The control system will activate the
ignition system and will attempt to light the burner for a
period of approximately 45 seconds. If unsuccessful,
the CHECK indicator lamp (D) will illuminate and the
GAS mode indicator lamp (C) will turn off.

To restart GAS operation, press the main power ON/
OFF button (1) to the OFF and then ON position. The
control system will attempt a new 45 second ignition
sequence.

If the refrigerator has not been used for a long time or
the LP tanks have just been refilled, air may be trapped
in the supply lines. To purge the air from the lines may
require resetting the main power ON/OFF button (1)
three or four times. If repeated attempts fail to start the
LP gas operation, check to make sure that the LP gas
supply tanks are not empty and all manual shutoff
valves in the lines are open. If the problem is still not
corrected, contact a service center for assistance.

C. STANDBY MODE OF OPERATION

This control system contains a feature where it will
continue to operate the cooling system in the event of a
failure of a major operating component. Two different
modes of operation can occur in this category.

If for some reason the display module becomes non­functional, the control system will revert to fully auto­matic operation – selecting the best energy source
available with AC and GAS priority. The temperature of
the refrigerator will be maintained at the MID position
within normal temperature tolerances. The power mod­ule will continually attempt to reestablish operation of
the display module.

The second standby mode of operation will execute
when a failure of the temperature sensing device or
associated electronic circuitry occurs. If this should
occur, the control system will operate on the energy
source selected via the control panel. The cooling unit
will run continuously on the selected energy source. The
refrigerator will continue to operate in this mode indefi­nitely or until a new sensor is installed and the system

Ice cubes can be made in the ice tray placed in the freezer
compartment. The tray should be filled with water to within
1/4" (5mm) from the top. For faster ice making, the tray
should be placed in direct contact with the freezer shelf.

To release the ice cubes, seize the tray with both hands
and twist the tray. Cubes not required should be replaced
in the tray. Refill the tray with water and replace the tray on
the freezer shelf.

Ice will be made more rapidly if the thermostat is set at its
highest position. It is a good idea to do this a few hours
before the anticipated need for ice, but be sure to move the
thermostat back to normal setting, usually about mid­setting when the ice is formed. Food in the lower compart­ment may be frozen if the setting is left on "COLDEST"

E. Inspect the flue baffle. It should be reasonably clean

and free of soot. Heavy soot formation indicates im­proper functioning of the burner. The flue and burner
both require cleaning in the following manner:

1) Unplug the refrigerator power cord from the 120 volt
AC outlet (see FIG. 6).

2) Disconnect or shut off the 12 volt power to the
refrigerator.

3) Turn manual shutoff valve to OFF. (See FIG. 6 &

12).

4) Remove cover from the burner housing. (See FIG .

6).

5) Disconnect the wire from the high voltage electrode.

6) Remove the burner mounting screws and remove
the burner assembly.

7) Remove the flue cap from top of flue tube and lift out
the wire and spiral baffle. Clean the flue from the top
using a flue brush. Blowing compressed air into the
flue will not properly clean soot and scale out of the
flue tube. Replace spiral baffle and flue cap.

8) Clean burner tube with a brush. Blow out burner with
compressed air.

9) Before removing burner jet, clean burner area of
soot and scale that fell out of flue tube. Remove the
burner jet. Soak the jet in wood alcohol and blow it
out with compressed air. Reinstall and tighten burner
jet.

10) Reinstall burner, being careful that the end of the
burner fits into the slot on the burner bracket.
Check to make sure slots are centered under the
flue tube and the thermocouple is positioned prop­erly (tip of thermocouple extends over two slots of
burner).

11) Be sure to reconnect the wire to high voltage
electrode. Check the electrode for proper location
and gap. (See FIG. 13).
