INTRODUCTION
In your own interest of safety, gas appliances should be installed by competent persons.
Failure to install the appliance correctly could invalidate any warranty or liability claims.
This appliance shall be installed in accordance with the manufacturers installation
instructions, local gas fitting regulations, municipal building codes, AG5601 and any other
relevant statutory regulations.
Data Label
The data label is located on the bottom right hand side panel near the front of the cooker.
A duplicate data label is supplied to adhere to an accessible area next to the
appliance.Ensure that the gas supply is Propane. This appliance is designed for use with
Propane Gas and should not be converted for use with any other gas.
Ventilation
The use of a gas cooking appliance results in a production of heat and moisture in a room
in which it is installed. Ensure that the kitchen is well ventilated and in accordance with
AG601 Installation Code. In general, the appliance should have adequate ventilation for
complete combustion of gas, proper flueing and to maintain temperature of immediate
surroundings within safe limits.
Location
Chose a location free of draughts and open doors and clear of combustible materials or
other fire hazards. The location should ensure convenience of operation and service. Any
adjoining wall surface situated within 200mm from the edge of any hob burner must be a
suitable non-combustible material for a height of 150mm for the entire length of the
hotplate.
Any combustible construction above the hotplate must be at least 600mm above the top of
the burner and no construction shall be within 450mm above the top of the burner. All
combustible materials such as curtains or shelves should be kept well clear of the cooker.

INSTALLATION
This cooker is designed for use in a marine environment and can be used as either a free-
standing appliance or can be mounted on built in gimbals. Used in its free-standing state,
the appliance must be placed on a firm, flat and stable structure and secured as shown in
Fig. 3.
Where the appliance is mounted on gimbals, there must be a minimum space of 50mm
behind the appliance. However, we recommend a space of 205mm behind the appliance,
allowing a 30°swing when in use at sea. The gimbals should be securely fixed to a
substantial surrounding structure as shown in Figs. 2 and 4.
The appliance must be positioned free from draughts, which may affect the combustion,
and in a manner that will prevent the accumulation of unburned gas. When in use ensure
that air vents are not inadvertently blocked or shut off.
Fitting the cooker
1. Remove the two screws towards the rear top of the cooker.(fig 5)
2. Replace the two screws with the addition of the fiddle rail.(fig 6)
3. Remove the two screws towards the front of the cooker and fit the front fiddle
rail.(fig 7)
4. Insert the pan holders and hold them in place with the pan holder knobs.
5. Inside the grill compartment you will find four small holes in the base. Take the grill
pan cradle with the double bars positioned towards the front and align the legs of
the cradle with the holes in the grill compartment base, then simply push the cradle
into the holes. The cradle is fitted in this way to enable easy access to clean
the grill compartment base.
Connection
Refer to the diagrams for its location. The appliance can be installed either fixed or
‘gimballed’ it is important to adhere to the instructions for the type of installation chosen.
Gimballed installation:-
A flexible hose must be used for connection to the gas supply and adhere to the
following requirements.
•Use a hose certified to AS/NZS 1869, Class D.
•A ¼” BSP female connection is provided at the rear to connect the hose
•The hose length MUST not exceed 1.2m.
•Hose is of adequate diameter for maximum gas consumption of appliance
•Ensure the hose will not kink or squash when using the gimbal.
•Ensure the hose is not likely to be damaged or cut.
•The hose should not come into contact with hot surfaces.
Fixed installation:-
All fixed installations must be connected by copper tubing, a ¼” BSP female
connection is provided at the rear.
This appliance is suitable for use on –
Propane Gas Only 2.75 Kpa.
It is important that the regulator should be set to the correct pressure for the type of gas
being used. Excessive pressure must not be permitted.
6

INSTALLATION
If the flame on either the top burners or the grill show a tendency to lift, it is probable that
the line pressure is too great. Should there be excessive yellow tips (resulting in sooting)
then it is probable that the line pressure is too low and, in either case, the burners should
not be used until the line pressure has been checked.
This appliance is fitted with the following injectors:-
BURNERS 0.62mm 5.4 MJ/h
GRILL 0.62mm 5.4 MJ/h
OVEN 0.59mm4.8MJ/h
The burners on this appliance have fixed aeration and no adjustment is necessary.
IMPORTANT
•After installation the appliance MUST be tested for soundness
•Test ALL burners on high and low flame for flame stability.
•The gas supply input pressure MUST not rise or fall significantly from
nominal when ALL appliances connected to the supply are operated
simultaneously. If NOT installed to the manufacturers instructions detailed
herein, we the manufacturer can not be held responsible for any problems
that occur, or poor performance that is perceived/witnessed.
When satisfied with the appliance, please instruct the user on the correct method of
operation. If the appliance fails to operate correctly after all checks have been made, refer
to the authorised service provider in your area.

USER'S INSTRUCTIONS
Each burner is controlled individually and is monitored by a flame failure sensing device, if
for any reason the flame goes out, the gas supply to the burner will shut off.
Using the Hob
To light the burner, depress and turn the knob anti-clockwise to the full rate position, apply
a light to the burner or press the ignition button if fitted. It is necessary to hold the knob
depressed during ignition and for approximately fifteen seconds after the burner has lit to
allow the flame failure sensing probe to reach temperature. Should the flame go out when
the knob is released, the procedure should be repeated holding the knob depressed for
slightly longer. If required the knob can be turned further anti-clockwise to the simmer
position – see Fig. 8 for knob positions.
To turn the burner off, rotate the knob fully clockwise until the dot on the knob lines up with
the dot on the fascia.
Using the Grill
Control of the burner is identical to the hob burners. Although the grill does heat up
quickly, it is recommended that a few minutes preheat be allowed. The grill pan should be
left in position to protect the base lining and the grill door MUST be left open while the grill
is in use.
A reversible grill pan trivet enables the correct grilling height to be achieved.
Fast Toasting Trivet in high position
Grilling Sausages Trivet in high position
Grilling Steak/Bacon Trivet in high position
Grilling Chops, etc Trivet in low position
Slow Cooking Trivet removed
Using the Oven
1. Ensure gas cylinder is connected and turned on. In the event of the smell of gas, turn
off at the gas cylinder and contact supplier.
2. Remove all accessories and packing that may be in the oven and clean the interior
before using it for the first time. Use soap and water and rinse carefully.
3. To light: Open door, push in control knob and turn to gas mark 9. Hold a lighted match
or taper to the burner and push and hold the control knob in. The burner should ignite
and the control knob should be held in for 10-15 seconds before release. If the burner
goes out, repeat the procedure, holding the control knob in for slightly longer.
4. For models fitted with spark ignition, the procedure is similar except that the burner can
be ignited by depressing the ignition button located on the fascia. Ignition must be
carried out with the oven door open and if the burner has not lit within 15 seconds the
control knob should be released and the oven left for at least one minute before a
further attempt to ignite the burner.
5. Place the oven shelf in the required position and close the door. Set the control knob to
approximately gas mark 5 and heat the oven for about 20 minutes to eliminate any
residual factory lubricants, which may impart unpleasant smells to the meals being
cooked.

6. To turn off: Turn the control knob until the dot on the control knob is aligned with the
dot on the control panel.
7. Flame Failure Device (FFD): The oven burner is fitted with a flame sensing probe
which will automatically cut off the gas supply in the event of the flame going out.
8. Oven shelves: The oven shelf has been designed to allow good circulation at the rear
of the oven and are also fitted with a raised bar to prevent trays or dishes making
contact with the back of the oven. To remove a shelf, pull forward until it stops, raise at
the front and remove.
Temperature Control
The temperature in the oven is controlled by a thermostatic gas tap and is variable over
the range 130 ºC to 240ºC. Approximate temperatures for the settings on the control knob
are shown in the table below. The temperatures indicated refer to the centre of the oven,
and at any particular setting the oven will be hotter at the top and cooler towards the base.
The variation between top to centre, and centre to bottom is approximately equivalent to
one Gas Mark. Good use can be made of the temperature variation in that several dishes
requiring different temperatures may be cooked at the same time. In this way maximum
benefit can be obtained from the gas used to heat the oven. Care should be taken not to
overload the oven; allow adequate spacing for free circulation of heat.

Cooking Guide
The baking tray and roasting tin provided are the largest that should be used in this size
oven. Larger items may well affect the circulation and heat distribution. Best results will be
obtained by following the shelf position in this guide
For best results preheat for 10 - 15 minutes. Most cookery books give detail of the shelf
positions and gas mark settings for each recipe. If in doubt about a recipe you intend to
use, study the recipe carefully, then find a similar dish in our guide and use our shelf
position and gas mark setting recommendation. Shelf positions are from the top down.
When roasting with aluminium foil care must be taken that the foil does not impair
circulation or block the oven flue outlet.
DO'S AND DON'TS
DO Read the user instructions carefully before using the appliance
for the first time.
DO Allow the oven to heat before using for the first time, in order to
expel any smells before the introduction of food.

Leaks
If a smell of gas becomes apparent, the supply should be turned off at the cylinder
IMMEDIATELY.
•Extinguish naked lights including cigarettes and pipes.
•Do not operate electrical switches.
•Open all doors and windows to disperse any gas escape.
•Propane gas is heavier than air, any gas escaping will therefore collect at low level.
The strong unpleasant smell of gas will enable the general area of the leak to be
detected. Check that the gas is not escaping from an unlit appliance.
•Never check for leaks with a naked flame, leak investigation should be carried out
using a leak detector spray.
Maintenance
This appliance needs little maintenance other than cleaning. All parts should be cleaned
using warm soapy water.
Do not use abrasive cleaners, steel wool or cleansing powders. When cleaning the burner
ring it is essential to ensure that the holes do not become blocked.
The control knobs are a push fit and can be removed for cleaning. They are
interchangeable without affecting the sense of operation.
On units fitted with battery spark ignition, when the time taken for spark generation
becomes extended, the battery should be renewed with a suitable make of long life
battery.
