INSTALLATION INSTRUCTIONS
REGULATIONS
The appliance must be installed only by authorised persons and in accordance with the manufacturer‟s
installation instructions, local gas fitting regulations, municipal building codes, AS 5601 –Gas Installations and
any other local authority, gas, electrical any other statutory regulations.
DATA LABEL
The data label is located on the front of the appliance. This appliance is suitable for Natural and Propane Gas.
Please ensure that the gas supply matches the Data Label ensuring that the gas supply is correct for the
appliance being installed and that adequate supply pressure and volume is available –refer to appliance data
plate for Mj/hr consumption, injector sizes of main burners/pilots, etc.
VENTILATION
It is strongly recommended that the appliance is installed under an extraction hood. Ventilation must be in
accordance with AS5601 - Gas Installations. 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.
This should comply with the following:-
The exhaust hood must be made from material which is impervious to fat, grease and vapour
The hood must be made so it can be readily and effectively cleaned
The hood must be made with its inside surfaces free of obstructions and all joints grease tight
The hood must be located so as to effectively ventilate the appliance and extend at least 150 mm
beyond the perimeters of the appliance.
The exhaust duct system must be adequately sized and must conform to all fire authority
requirements and must not be connected to any other ventilation or exhaust systems
Unless adequately protected the hood and ductwork must be fitted at least 450 mm from any
combustible material and so that the lower edge of the hood is no more than 2 meters from the floor
COMBUSTIBLE SURFACES
Ensure appliance is installed on a flat, solid, non-combustible floor.
The appliance must be installed so that;
There is a clearance of at least 150mm from combustible material at the sides.
There is a clearance of at least 50mm from combustible materials at the rear.
GAS CONNECTION
Unpack the appliance and remove any protective coating.
Place the appliance into its installed position and adjust the legs to the right height and stability.
The 20 mm gas connection is on the right hand side 100 mm above the floor and 220 mm from the front.
Install the regulator supplied to the gas inlet ensuring that the direction of flow arrow is the correct way.

BEFORE CONNECTING NEW PIPE TO THIS APPLIANCE, THE PIPE MUST BE BLOWN OUT THOROUGHLY TO
REMOVE ALL FOREIGN MATERIAL. FOREIGN MATERIAL IN THE BURNER AND GAS CONTROLS WILL CAUSE
IMPROPER AND DANGEROUS OPERATION.
Connect to gas.
PRESSURE TEST POINT
All appliances that are dispatched from our factory are tested and adjusted according to the specifications for
the required gas type. The regulator may require adjustment to achieve required gas pressure.
Check the burner pressure at the test point on the regulator. The test point pressure should be adjusted to
1.00 kPa –Natural gas or 2.55 kPa –Propane gas with the burners operating at maximum.
BEFORE LEAVING -COMMISSIONING
Check all connections for gas leaks with soap and water. Do not use a naked flame for detecting leaks.
Ignite the pilot and main burners as prescribed below to ensure correct operation of gas valves, burners and
ignition. When satisfied with the operation of the appliance, please instruct the user on the correct method of
operation. Ensure that this instruction manual is left with owner of the appliance.
COMMISSIONING (BOILING TOP SECTION)
If appliance fitted with pilot and/or flame failure
A. Ensure gas control is in the „OFF‟ position.
B. Depress operating knob of relevant burner and turn anti-clockwise to „PILOT‟ position and light pilot.
C. Observe the pilot light is established. Pilot flame should be between 10-20mm in size and be in direct
contact with thermocouple (where fitted). Should the thermocouple require adjustment, lift off trivet
and undo the nut holding thermocouple on pilot assembly. After adjusting reassemble in reverse
order.
D. If pilot light does not light, turn control knob to „OFF‟ position, wait five minutes and repeat steps A to
C.Note. If pilot flame is smaller than the parameters described in part A, check the pilot gas line
(6mm stainless steel flexible tube) for any possible blockages/crimpage. To gain access to gas control
components, remove control knobs and undo screws located on either side and at the top of the front
panel. Remove front panel (reassemble in reverse order).
E. Once pilot is established turn control knob anti-clockwise to the „HIGH‟ position. Examine flame.
F. Turn control knob clockwise to the „LOW‟ position. Examine flame. Should flame extinguish when on
the low position, adjust flame adjustment screw on gas cock. To gain access to gas cock, gently
remove gas cock knobs from front of appliance and remove screws holding front panel in position.
Screw flame adjustment screw anti-clockwise for greater flame on lower setting, clockwise for less
flame on low setting. REASSEMBLE IN REVERSE ORDER.
G. Turn control knob clockwise to the „OFF‟ position.
H. Repeat steps A to Hfor all burners.
If appliance is not fitted with pilot and/or flame failure.
A. Ensure gas control is in the „OFF‟ position.
B. Depress operating knob of relevant burner and turn anti-clockwise 180oto the „LOW‟ position and light
burner. Examine flame. Should flame extinguish when on the low position, adjust flame adjustment
screw on gas cock. To gain access to gas cock, gently remove gas cock knobs from front of appliance
and remove screws holding front panel in position. Screw flame adjustment screw anti-clockwise for
greater flame on lower setting, clockwise for less flame on low setting. REASSEMBLE IN REVERSE
ORDER.

The pilot should remain alight. Observe the pilot light is established. Pilot flame should be between
10-20mm in size and be in direct contact with thermocouple (where fitted). Should the thermocouple
require adjustment, lift off oven chamber baffle and undo the nut holding thermocouple on pilot
assembly. After adjusting reassemble in reverse order. Note. If pilot flame is smaller than the
parameters described in part C, check the pilot gas line (6mm stainless steel flexible tube) for any
possible blockages/crimpage.
D. If pilot light does light, wait five minutes and then repeat steps A. to C.
E. Turn the control knob to the desired temperature.
F. Inspect oven burner flame which should burn sharp and in a rich blue color. Adjust aeration of oven
burner if/as required (refer oven burner aeration below).
G. Turn control knob to „OFF‟ position. Observe flame is extinguished.
H. Depress pilot extinguish button and observe pilot light is extinguished.
Adjusting aeration of oven burner (if required)
If necessary to adjust aeration to oven burner;
The butterfly valve sits at the inlet of the burner on the RHS. For better access remove the RHS
deflector plate above the burner.
oLoosen screw on butterfly valve at the inlet and adjust.
oReplace deflector and light.
oRepeat the process if necessary to achieve optimum flame.
In the event the appliance fails to operate correctly, check the following;
1. Data plate to ensure correct gas type and pressure (adjust if necessary).
2. Adjust aeration by adjusting air shutters.
3. Injector sizes –check against data plate and installation manual.
