Gas Connection
NOTE: ALL GAS FITTING MUST ONLY BE CARRIED OUT BY A QUALIFIED PERSON.
1. The Gas Ovens do not require an electrical connection, as they function totally on the as
supply only.
2. It is essential that the as supply is correct for the appliance to be installed and that
adequate supply pressure and volume are available. The followin checks should
therefore be made before installation:-
a. Gas Type required for the appliance is shown in the ratin label. Check that this is correct for
the as supply the appliance is bein installed for. The as conversion procedure is detailed
in this manual.
b. Supply Pressure required for this appliance is shown in the ‘Gas supply requirements’ section
of this manual. Check the as supply to ensure adequate supply pressure exists.
c. Input Rate of this appliance is stated on the Ratin label .The input rate should be checked
a ainst the available as supply line capacity. Particular note should be taken if the appliance is
bein added to an existin installation.
NOTE: It is important that adequately sized pipin runs directly to the connection joint on the
appliance with as few tees and elbows as possible to ive maximum supply volume.
NOTE: Ensure the re ulator is converted to the correct as type that the appliance will operate on. The
re ulator outlet pressure is fixed ex-factory for the as type .
3. Correctly locate the appliance into its final operatin position and usin a spirit level, adjust
the le s so that the unit is level and at the correct hei ht.
4. Connect the as supply to the appliance throu h the re ulator. A suitable jointin compound

Operation
WARNING:
SURFACE TEMPERATURE OF THE GRIDDLE CAN REACH OVER 300°C WHEN THE APPLIANCE IS OPERATED
AT FULL SETTING.
1. Lighting the Top Burners
The burners are fitted with individual standin pilots which allows the main burners to be turned ON-
OFF without the need to manually re-li ht the burner each time that it is turned ON, as the burner
will be automatically lit itself by the pilot burner.
Flame Failure Protection is incorporated for each burner by way of a thermo-electric system which will
shut off the as supply to that burner in the event that the burner oes out, so that un-burnt as is not
expelled.
1. Select the burner required, depress and turn the correspondin as control knob anti-
clockwise to the ‘PILOT’ position.
2. With the as control knob depressed, manually li ht the pilot burner or use the piezo i niter
provided (optional).
3. Release the as control knob after approximately 10-20 seconds after li htin the pilot
burner.
4. The pilot burner should stay ali ht - if not, repeat Steps (b. to c. above.)
5. ‘Full Flame’ can now be achieved by depressin and rotatin the as control knob anti-
clockwise to the first stop 'HIGH' flame position.
6. Low flame can be achieved by depressin the as control knob and rotatin fully anti-
clockwise to the ‘LOW' flame position.
7. To achieve simmer control, depress the as control knob and rotate between the ‘HIGH’
and ‘LOW’ positions to achieve the temperature required.
2. Turning 'OFF' the Main Burners / Pilots
1. To turn off the main burner, but keep the pilot burner ali ht, rotate the as control knob to the
'PILOT' position. The main burner will extin uish and the pilot will remain ali ht.
2. To turn off the 'PILOT', depress and turn the as control knob clockwise back to the ‘┃’
position. The 'PILOT' burner will extin uish.
3. Lighting Oven
The oven is controlled by a knob on the front control panel.
To li ht the pilot of an oven, do the followin :
1. Turn oven thermostat to “Pilot” position.
2. Depress the as control knob.
3. Li ht the pilot.
4. Hold in the as control knob for approximately 10-15 seconds, then release. The pilot flame will
established.

13
Operation (Continued)
Main burner air supply:
1. For efficient burner operation, a proper balance of as volume and primary air supply must
be maintained which will result in complete combustion. Insufficient air supply results in a
yellow streamin flame. Primary air supply is controlled by an air shutter on the front of the
burner.
2. Loosen the screws on the front of the burner and adjust the air shutter to just eliminate
the yellow tips of the burner flame. Lock the air shutter in place by ti htenin the screws.
CAUTION
The space between the le s at the bottom admits combustion air. DO NOT BLOCK THIS SPACE.
All burners are lit from constantly burnin pilots. Turnin the valve to the desired flame hei ht is all
that is required to put the unit in service.
Do not permit fans to blow directly at the unit. Wherever possible, avoid open windows next to the
units' sides or back. Avoid wall type fans which create air cross-currents within a room.
It is also necessary that sufficient air should be allowed to enter the room to compensate for the
amount of air removed by any ventilatin system. Otherwise, a subnormal atmospheric pressure
will occur, affectin operation and causin undesirable workin conditions.
A properly desi ned and installed hood will act as the heart of the ventilatin system for the room
or area in which the unit is installed, and will leave the unit independent of chan in draft
conditions.
All valves must be checked and lubricated periodically. This must be done by an authorized service
representative in your area.
Note:
Please wait at least 15 seconds to restart the main burners to maintain the best function of the
thermostat valve after turnin off the main burners.
IMPORTANT
Should any abnormal operation like;
- i nition problems,
- abnormal burner flame,
- burner control problems,
- partial or full loss of burner flame in normal operation, be noticed, the appliance requires IMMEDIATE
service by a qualified service person and should not be used until such service is carried out.

14
Cleaning and Maintenance
INITIAL CLEANING:
Prior to operatin your new oven, thorou hly wash the exterior with a mild deter ent or soap
solution. Do not use abrasive cleaners, since this mi ht dama e the cabinet finish. If the stainless
steel surfaces become discolored, scrub by rubbin only in the direction of the finished rain.
When the oven is first heated, it will smoke until oil used in manufacturin , preservation and dust
from stora e and shippin are burned off. An hour at "max." on all burners is usually sufficient.
DAILY CLEANING:
Remove, empty, and clean rease drawers and dirt trays.
Clean riddle drain chutes.
VENT SYSTEM
At least twice a year the unit ventin system should be examined and cleaned.
Followin daily and periodic maintenance procedures will enhance lon life for your equipment. Climatic
conditions (such as salt air) may require more thorou h and frequent cleanin or the life of the
equipment could be adversely affected.
STAINLESS STEEL SURFACES
1. To remove normal dirt, rease and product residue from stainless steel that operates at LOW temperature,
use ordinary soap and water (with or without deter ent) applied with a spon e or cloth. Dry thorou hly with
a clean cloth.
2. To remove rease and food splatter, or condensed vapors, that have BAKED on the equipment, apply
cleanser to a damp cloth or spon e and rub cleanser on the mental in the direction of the polishin lines will
not mar the finish of the stainless steel. NEVER RUB WITH A CIRCULAR MOTION. Soil and burnt deposits
which do not respond to the above procedure can usually be removed by rubbin the surface with SCOTCH-
BERITE sourcin pads or STAINLESS sourcin pads. DO NOT USE ORDINARY STEEL WOOL, as any particles
left on the surface will rust and further spoil the appearance of the finish. NEVER USE A WIRE BRUSH,
STEEL SOURCING PADS (EXCEPT STAINLESS), SCRAPPER, FILE OR OTHER STEEL TOOLS. Surfaces which
are marred collect dirt more rapidly and become more difficult to clean. Marrin also increases the possibility
of corrosive attack. Refinishin may then be required.
To remove heat tint- Darkened areas sometimes appear on stainless steel surfaces where the area has
been subjected to excessive heat. These darkened areas are caused by thickenin of the protective surface
of the stainless steel and are not harmful. Heat tint can normally be removed by the fore oin , but tint
which does not respond to this procedure calls for a vi orous scourin in the direction of the polish lines,
usin SCOTCH-BRITE sourcin pads or a STANILESS sourcin pad in combination with a powered cleanser.
Heat tint action may be lessened by not applyin , or by reducin heat to equipment durin slack periods.
BURNERS- GENERAL
Little attention is needed, but if spilla e should occur, it may be necessary to clean around pilot areas, air
mixer and under burners. Use a wire brush if necessary.
Periodically, burners (particularly open top type) should be removed and cleaned. Allow interior to drain. Dry
thorou hly before replacin .
HOT TOPS
Allow ran e to cool. If water is used on tops while still hot, they may crack. Avoid this practice. Remove tops
from ran e and clean surfaces with hot water and deter ent. A wire brush may be used on the underside of
the hot pot plate. It is recommended not to clean tops while still on ran e, even if cooled, as excessive
water will drip into the burner box and deteriorate the metal.

15
Cleaning and Maintenance (Continued)
Do not waste as and abuse equipment by leavin all burners “FULL ON”, if not required. Durin idlin
periods, adjust burner valves to keep top warm. Re-adjust burner valves as required for periods of heavy
loads.
CARE OF GRIDDLES
New riddles should be carefully tempered and cared for in order to avoid possible dama e. To break in a
new riddle, first wipe it clean. Next, li ht all the riddle burners and turn them to low for one hour. Then
radually brin each riddle up to fryin temperature. Next, spread three or four ounces of beef suet, or as
a substitute, bakin soda, to season it. Never allow water on a hot riddle and never wash it with soap and
water.
Use a Norton Alundum Griddle Brick to clean the riddle. Always remember to heat riddle slowly because
quick heat may cause costly dama e. Griddle plates cannot be uaranteed a ainst dama e due to
carelessness. Never place utensils on riddle. Do not overheat riddle above 575F (300℃), as this will
cause warpa e or breaka e.
Do not use any type of steel wool. Small particles may be left on the surface and et into food products. Do
not clean spatula by hittin the ed e on the riddle plate. Such action will only cut and pit the riddle plate,
leavin it rou h and hard to clean.
Do not waste as or abuse equipment by leavin valves at “FULL ON” position or thermostat at hi h
temperature if not required. Durin idle periods, set valves at “LOW” position or thermostat to low
temperature settin s to keep riddle warm. Reset valves or thermostats, as required, for periods of heavy
load. Turn valves or thermostat to “OFF” at the end of daily operation.
OPEN TOP PLATE
Remove enameled top plate and spiders, clean with a solution of hot water and stron soap or deter ent.
The area around the char e port, where the splash tube is attached to the burner, must be free from any
spilla e or residue, or other obstructions.
The splash tubes must be clean and properly ali ned with the pilot housin to insure ood top burner
i nition. Pilot should be 12 to 15mm blue flame. Avoid carbon producin tip or unstable blowin or liftin of
flame.
OVEN INTERIOR
Allow oven to cool. Remove porcelain enameled oven bottom. Clean by rubbin with stron deter ent and
Brillo pad or similar scrubber. “Spill-over” should be cleaned from the bottom as soon as possible to prevent
carbonizin and a “burnt-on” condition. For stubborn accumulations, commercial oven cleaners are
recommended.
The porcelain oven door linin can be cleaned in a similar manner.
The side, rear and top linin should be wiped only with a cloth dampened with a mild deter ent and water.
Avoidin usin excessive amounts of water, as this may drip into burner compartment and deteriorate the
metal in that area. Do not use stron commercial cleaners or abrasive pads on the side, rear or top linin s, as
they may dama e the finish or leave ray residue.
NOTE:
•
If the as Oven usa e is very hi h, we recommend that the weekly cleanin procedure is carried
out on a more frequent basis.
•
Ensure that protective loves are worn durin the cleanin process.
•
DO NOT use harsh abrasive deter ents, stron solvents or caustic deter ents as they will dama e
the rate and burners.
•
DO NOT use water on the cookin rid while they are still hot as warpin may occur.
Allow these items castin s to cool and remove for cleanin .
•
Parts protected by the manufacturer or his a ent are not to be adjusted by the installer, unless the
installer is an authorized service a ent Weekly

All open-top burners are primarily adjusted by means of an air shutter on the mixer face.
To adjust a burner, loosen the screw that holds the air shutter in position and rotate the mixer cap until a
clear, stable blue flame is obtained. The flame should not be yellow tipped nor should it blow off the burner
ports.
All orifice sizes and burner rate are properly set at the factory and should not be altered.
Over-rated burners cause poor burner and pilot performance, resultin in less heat, and wasted as.
OVEN BURNER FLAME
The oven burner orifice is of the fixed type, sized for the specified as supply. The burner flame
characteristics are controlled by varyin the primary air mixer cap. There should be a clear blue flame with a
distinct inner cone at each port. Excessive primary air can result in "blowin " or the flames leavin the ports.
Lack of primary air causes soft or yellow tipped flame.
OVEN LOW FLAME LEVEL SETTING
When the oven reaches the temperature at which the dial is set, the oven thermostat reduces the flow of as
to the amount required to keep the oven at that temperature. However, the thermostat must always supply
enou h as to keep the entire burner li hted. To maintain this minimum flame, the low flame settin must be
set carefully and accurately usin the followin procedure:
1. Turn on the oven and set the oven thermostat to 200°C.
2. When the oven reaches this temperature, the flame will reduce to the low flame settin .
3. Open the kick panel and look throu h the pilot hole to see if the flame is even and minimal alon the entire
len th of the burner. Also open and close the oven door to ensure the low flame does not extin uish. If the
flame is even and minimal and the flame does not extin uish then, the low flame settin level does not need
adjustment. If the flame extin uishes, then continue with this procedure to adjust the low flame settin .
4. Remove the control knobs, thermostat dial (usin an allen key to loosen a screw on the side) and the front
panel.
5. Usin a screwdriver, turn the low flame settin adjustor on the stem of the thermostat counterclockwise to
increase the flame or clockwise to decrease the flame until the flame is even and minimal alon the entire
len th of the burner.
6. Replace the front panel, control knobs, and thermostat dial. Turn all control knobs to the OFF position.
