Installation

For best performance at high ambient temperatures, there must be free air
circulation over the cooling unit at the rear of the refrigerator.

Ensure that there is a free air space above the refrigerator and that the flue
(chimney) on top of the cabinet is not covered in any way. Do not place the
refrigerator in a space where air circulation is restricted. Follow “clearance”
instructions.

This free-standing refrigerator requires accessibility to the back for servicing the
gas equipment, which can be obtained by using a certified Flexible Metal
Connector to allow the refrigerator to be withdrawn without disrupting the gas
supply. “Where a flexible metal connector is used, it must comply with local
authorities and in Canada with the provisions of the current Standard CAN 1-

6.10, Metal Connectors For Gas Appliances”. However, if the Local Authorities
require a rigid gas supply connector, the refrigerator should be located with
sufficient space at the back for servicing or, if located against a wall a removable
panel of a minimum size of 16” x 20” should be provided in the wall to allow
access to the rear of the refrigerator. If you purchased a CM (CO Monitor model)
you must follow instructions in Section 6 - 5.0 onward.

Heat Shield

The heat shield must be installed before
operating the appliance. This is a CSA
requirement.

Un-wrap the heat shield (located inside
the box along with the appliance). Mount
heat shield with the screws (supplied) to
left side of the fridge. See diagram.

Clearances

Minimum clearances to combustible materials are:
Top – 6”
Sides – 2”

Rear – 0” with left hand side rear sheild mounted
as shown in Figures. 1, 2 & 3.

Note: DO NOT install the appliance directly on carpeting. Carpeting must
be removed or protected by a metal or wood panel beneath the appliance,
which extends at least the full width and depth of the appliance.

ir Flow - to release heat trap

• Fig#1 - This is ideal as both top and sides are open

• Fig#2 – During hot/humid weather this confined area will become very

warm. To reduce heat build-up, we recommend providing an area for two air
vents to circulate the air. One placed 6” off the floor and the other at or above
the appliance top. Cold air return vents with adjustable louvers, works very
well. This will allow hot air to evacuate the area and assist in air flow across the
fins (similar to air passing across a radiator) – See Fig #4

• Fig#3 – If this is your opening you only need to stay the diagramed distance

from the wall and ceiling. There is no need for additional circulation.

UGP 10

Gas Connection

Hook-up to the gas supply line: 3/8” SAE (UNF 5/8” - 18) male flare connection. A
backup wrench must be used when tightening gas supply fitting. All completed
connections should be checked for leaks with a non-corrosive leak detector and/or
soap and water for a bubble check..

WARNING – DO NOT USE FLAME TO CHECK FOR GAS LEAKS

The gas supply system must incorporate a pressure regulator to maintain a supply
pressure of not more than 12” water column and no less than 11” water column. (max
setting)

Make sure the refrigerator and any other high BTU appliances on your line are turned
on when checking the gas pressure. The appliance and its individual shut-off valve
must be disconnected from the gas supply piping system during any pressure testing of
that system at pressures in excess of ½” psig.

In case detailed instructions on the installation and connection of the gas supply are
required, contact your dealer or distributor.

Lev eling

Ensure the fridge is level by using a 2ft level, this is accomplished by adjusting the
feet at the front, underneath the fridge.

General Operating Instructions

Importance of Leveling a Refrigerator

The refrigerator must be adjusted to a vertical position in both directions. In an
absorption refrigeration system, ammonia is liquefied in the finned condenser coil at
the top rear of the refrigerator. The liquid ammonia then flows into the Evaporator
(inside the freezer section) and is exposed to circulating flow of hydrogen gas, which
causes the ammonia to evaporate, creating a cold condition in the freezer.

When starting this refrigerator, the cooling cycle may require up to four hours of
running time to begin cooling before the cooling unit is fully operational, you can then
begin slowly loading the compartment.

The tubing in the evaporator section is specifically sloped to provide a continuous
movement of liquid ammonia, flowing downward by gravity through this section. If
the refrigerator is operated when not level, 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. Warranty will not
cover recharge/rebuild if caused by not running the fridge level.

This refrigerator operates only on LP Gas (Propane)

Note: After changing an LP tank, or after a long shut off period, the gas line is likely to be filled with
air. You may have to repeat the lighting procedure several times to purge the air out of the gas lines.We
suggest first turning off gas at the control panel, then the tank,this will reduce an air trap in the gas line.

Gas Operation

1. To start the refrigerator, turn the thermostat knob B to maximum setting (fully

clockwise).

2. Turn button C to Gas “on” position, then push same button in and hold.

3. Immediately push button A repeatedly for the piezo igniter to light the burner.

Continue to hold the C button until you see the flame at the burner head . This
can be observed looking thru the control panel area at the rear left corner . Hold in
the C button for 20 seconds then release pressure. Burner should remain on.

4. Adjust the thermostat knob to desired temperature setting after 4 to 8

hours of operation.

“Shut Down” Procedure

1. Turn knob C to Gas “Off” position.

Note: If using CO-Monitor, the monitor must be hooked up and be reset with
the battery installed for the flame to stay on – Refer to Chapter 6

CONTROLS – See Fig 5. for description of controls

Figure #5

Thermostat

The refrigerator cooling temperature is controlled by a combination thermostat that
can be adjusted by turning knob B to different settings to maintain the desired
refrigerator temperature. Knob C also incorporates a safety device which automatically
shuts off the supply of gas if the flame goes out. The piezo electric igniter discharges
sparks onto the burner when the button is pushed. See Figure #5

1. “DEF” Defrost Setting on the Gas Thermostat: In gas operation, the thermostat
closes its main valve and the burner runs continuously at the bypass rate or pilot
flame.(turn fully counter clockwise)

2. “MAX” Setting of the Thermostat: In gas operation, the thermostat allows the
burner to remain on high flame continuously. (turn clockwise)

3. The thermostat can be adjusted between “Max” and “Defrost” to obtain the desired
fridge temperature.

When the thermostat reaches the set temperature, it will reduce the burner back to
bypass operation.

7

UGP 10

The setting of the thermostat is critical and recommend it be adjusted to maintain a
dry frost on the cooling fins (approx 38° Freinhight or 3° Celcius) . Adjust the

thermostat knob closer to “Max” (clockwise) when the ambient temperature rises.

How T o Use The Refrigerator

FOOD STORAGE COMPARTMENT

The food storage compartment is completely closed and unventilated, this is necessary
to maintain the required low temperature for food storage. The coldest areas in the
refrigerator are under the cooling fins and at the bottom of the refrigerator. The
warmer areas are on the upper door shelves. This should be considered when placing
different types of food in the refrigerator.

FROZEN FOOD STORAGE COMPARTMENT

Quick freeze soft fruits and ice cream should be placed in the coldest part of the
compartment which is at the bottom of the aluminum liner. Frozen vegetables, may be
stored in any part of the compartment.

This compartment is not designed for deep or quick freezing of food. Meat or fish,
whether raw or prepared, can be stored in the frozen food storage compartment
provided they are pre-cooled in the refrigerator. To prevent food from drying out,
keep it in covered dishes, containers, plastic bags or wrapped in aluminum foil.

Defrosting

Frost will gradually accumulate inside the refrigerator and freezer surfaces. It must not
be allowed to grow too thick as it acts as an insulator and adversely affects the
refrigerator performance. Check the formation of frost every week and when it
exceeds 1/16” thick, defrost the refrigerator.

Shut off and empty the refrigerator, leaving the fridge and the freezer doors open.
Defrosting time can be reduced by filling the ice tray with hot water and placing it in
the freezer compartment.

DO NOT USE A HOT AIR BLOWER, PERMANENT DAMAGE

COULD RESULT

OR ANY OTHER SHARP TOOLS TO REMOVE FROST

FROM THE FREEZER COMPARTMENT

FRIDGE SECTION

, DO NOT USE A KNIFE, AN ICE PICK,

.

UGP 10

Inside the refrigerator compartment, the defrost water runs from a collector channel to
a drip tray/cup at the rear of the refrigerator where it normally evaporates. If heavy
frost has built up on the cooling fins creating a lot of defrost water, Beware your water
reservior may overflow, we suggest you inspect reservoir before/after cycle.

FREEZER SECTION

This area must be wiped down with cloths to remove water after defrosting, there is no
drain for this compartment

When all frost is melted in the freezer compartment & interior of the refrigerator it
should be wiped up with a clean cloth. Replace all food and set the thermostat to its
normal position.

Cleaning

Cleaning the refrigerator is usually done after it is defrosted or put into storage. To
clean the interior liner of the refrigerator, use a lukewarm water and weak soda
solution. Use only warm water to clean the finned evaporator, gasket, ice trays and
shelves.

Never use strong chemicals or abrasives to clean these parts as the

protective surfaces will be damaged. It is important to always keep the

refrigerator clean. Dishwasher detergent is recomended

Interior Light

The interior light is located inside the fridge compartment, at the upper right hand side.
To gain access to the light bulb you must first remove the cover, this is done by pulling
the cover toward you, this will pop the cover off. Once the bulb is exposed you can
replace it by unscrewing counter clockwise.

4 x “D” size batteries operate the interior light, the battery compartment is located on
the exterior back of the fridge, approx 7” above the floor.

Shut Down Procedure

A. Turn gas valve knob “C” to the “off” position
B. If the refrigerator will not be in operation for a period of weeks, it should be

emptied, defrosted, cleaned and the doors left open. The ice tray should also be
dried and kept outside the cabinet, also turn off gas at gas control then the main
supply source.

the refrigerator operating properly. Installation must be by a licensed gas fitter in
accordance with local codes or must comply with Propane Installation Code
CAN/CGA-B149.2 (latest edition)

REFRIGERATOR REMOVAL

Before working on the refrigerator, shut off the gas supply. Disconnect the gas supply
line at the rear of the refrigerator. Always use a back up wrench when loosening and
tightening this connection. Cap the gas supply line and remove the refrigerator.
Replacement is the reverse of removal. Check all connections for gas leaks.

Refer to Chapter 2 INSTALLATION

PERIODIC MAINTENANCE

Before working on refrigerator, shut off the gas supply. Disconnect the gas line at the
rear of the refrigerator. Always use a back up wrench when loosening and tightening
this connection. Cap the gas supply line and remove refrigerator. Replacement is the
reverse of removal. Check all connections for gas leaks. Refer to Chapter 2,
Installation.

To keep your refrigerator operating effectively and safely, periodic inspection and
cleaning of several components is recommended once or twice a year, sometimes more
often depending on environment.

• It's important to keep the area at the back of the refrigerator clean. Clean the coils

on the back of the refrigerator. Use a soft bristled brush to dust off
the coils.

• Check all connectors in the complete refrigerator LP gas system for gas leaks.

Note:

The following maintenance is required at least once or

twice a year at least, more often based upon usage/environment.

The LP gas supply must be turned on. Apply a non corrosive bubble solution
