INTRODUCTION

GOLDSTEIN CHINESE WOK GAS RANGE ALL MODELS

GOLDSTEIN WOKS are designed to give long and satisfactory service and

incorporate the best possible materials and workmanship. Proper
installation, adjustment and preventative maintenance are vitally important if
efficiency and appearance are to be maintained.

Read these instructions carefully as they contain important safety
information regarding the installation, use and maintenance of the appliance.

RECEIVING INSPECTION

•

Check crates for handling damage. After carefully uncrating, check for
“concealed” damage. Report any damage immediately to carrier and to dealer.

•

Remove check all loose items from unit and check contents as found on back of
warranty cards.

•

Check type and capacity of gas supply.

•

The type of gas for which this Wok Series is factory adjusted can be seen on
the rating plate, e.g. Approval No. Serial No, mj/M, Model, Test pressure point,
kPa and injector sizes located on the bottom front panel of the Wok.

“THE EQUIPMENT MUST BE INSTALLED BY A

LICENSED GASFITTER

2. INSTALLATION INSTRUCTIONS

PRE-INSTALLATION OF THE WOK

•

Check that there is sufficient clearance between doors and passageways to
move equipment into the cooking area.

•

Lift off wooden base.

•

Lay the Wok back on its back.

•

Place a piece of timber under the body of the Wok not on the Upstand to allow
clearance for your hand.

•

Attach the legs using bolts and washers provided and tighten them.

•

Then lift the Wok off its back being sure to lift on the body by placing hands
under space provided by timber.

•

Single hole Woks mount directly on the stand provided.

•

Peel off all protective film and remove any glue or oil with a suitable solvent.

INSTALLATION (FOR AUTHORISED GASFITTERS ONLY)

These installations MUST comply with the requirements of AS5601/AG601 local
authority gas, electricity and any other statutory regulations.
LPG connection MUST be supplied and connected with regulator as per standard
AS4563/AG300. With every wok that has the two burner option there will be two
regulators supplied, and with CWA-3B2 a standard Bromic 980L for the B2 and a
Jeavons J78R for the 3 burners, due to exceeding 250Mj.

Note: AFTER ANY MAINTENANCE OR ADJUSTING OF GAS CONNECTED
COMPONENTS, A GAS LEAK TEST MUST BE CARRIED OUT, TO ENSURE
THERE ARE NO GAS LEAKING HAZARDS

• Adequate ventilation must be provided by a hood with vent and exhaust fan.

• Check the rating plate to ensure appliance is suitable for the gas supply to

which it will be connected and for information relative to gas input pressure
and consumption.

Please follow instructions carefully:

1. Set the unit in correct position (ENSURE THERE IS A MIN 200MM REAR

WALL CLEARANCE and 225mm SIDE ALL CLEARANCE FROM
COMBUSTIBLE MATERIALS AND THAT THE UNIT IS PLACED ON A
FIRE PROOF BASE) and adjust feet using a spirit levelling side to side and

front to rear. If more than one piece of equipment is in the line up, these
adjustments will have to be made relative to each other.

2 Have a licensed gas fitter or your local gas company connect the appliance

to the gas supply. The gas inlet connection can be seen on Page 9. The
appliance must be installed in accordance with rules of any authority having
jurisdiction. The regulator supplied must be installed on the gas inlet to the
appliance.

The pressure regulator (NG) and LPG standards (AS4563/AG300 1.1.05)
are supplied as a loose item and a hand stop tap must be supplied as
close to the appliance as possible.

2. INSTALLATION INSTRUCTIONS

3. DRAIN CONNECTION
The drain must be connected in conformity with requirements of local

authority. The diameter of the drain pipe must always be greater than the
drain outlet from the appliance. Drain connection is 51 mm BSP.

4. All gas equipment MUST have an exhaust hood as per AS5601/AG601.

5. WATER CONNECTION
The unit is fitted with a flow controlled timer tap to control the flow of water to
the swivel arm at the rear. The appliance must be connected to a cold water
supply with pressure between 2 and 5 bar (300 kPa to 750 kPa).

3. COMMISSIONING INSTRUCTIONS

COMMISSIONING (FOR AUTHORISED TECHNICIANS ONLY)

Note: All the appliances that leave our factory have been tested and adjusted
according to the specifications for the required gas. The regulator may have
to be adjusted to achieve the required gas pressure.

Note: Before igniting the wok ensure that all the protective plastic on unit has
been removed.

Each wok burner is fitted with an adjustable pilot (black knob) and a control for the
wok burner. The pilots should be ignited with a hand sparking unit.

After installation of the appliance the installer should light all burners to ensure that
they are operating correctly. The burner flames should not have yellow tips nor
should they be too “hard”.

All appliances are tested and preset before leaving our factory, but small
adjustments may be necessary to suit local conditions.

Ensure that the pressure at the pressure test point on the manifold is as per the
rating plate.. If the two values are not the same, use a screwdriver to adjust the
pressure regulator (turning screw clockwise will increase the pressure).

Flame Failure

Turn the control knob to low and check that the flame size has decreased
substantially. If flame has not decreased, then using a small flat headed
screwdriver adjust the ‘min gas screw’ on the front of the gas control until the min
flame gets to desired size (turning screw clockwise will decrease the flame size).

If the appliance fails to operate correctly, check the following:

1. Data plate for correct gas type and pressure and adjust if necessary.

2. Correct aeration by adjusting the interrupter screws on the side of the burner
head (twin ring burner only). The flame should have a purple inner cone and
a blue out cone.

3. Injector size – check against data plate.

4. Check pilot flame size and adjust if necessary.

CAUTION WARNING

If flame or pilot goes out wait (5) minutes before relighting (reigniting).

Air Cooled Wok-All Models May 2011

4. CLEANING/MAINTENANCE OF CHINESE WOK

DO NOT USE STEEL WOOL, ABRASIVE CLOTHS, CLEANSERS OR
POWDERS!

If it is necessary to scrape stainless steel to remove encrusted materials, soak
the area with hot cloths to loosen the material, and then use a wood or nylon
scraper.

DO NOT USE a metal knife, spatula, or any other metal tool to scrape stainless
Steel. Scratches are almost impossible to remove

CLEANING

For continued reliable operation of your Wok, regular cleaning is most essential.
Spillages of food products or liquids on the Wok will occur and these must not be
allowed to “burn on” (these spillages should be immediately cleaned up).

For the cleaning of the stainless steel or vitreous enamel surfaces, use hot soapy
water and a soft cloth. Never use an abrasive cloth.

A CLEANER THAT IS COMPATIBLE WITH ALUMINIUM MUST BE USED
ON THE EQUIPMENT OTHERWISE THE GAS PIPING WITHIN THE UNIT
WILL BE DAMAGED AND THIS WILL AUTOMATICALLY VOID THE
WARRANTY.

SERVICE

An authorised person must handle any service problems that arise. If Authorised
Gasfitter cannot commission or adjust appliance they can contact the state branch
on Page 16. The operator should carry out only regular cleaning.

WARNING

NO FLAMMABLE MATERIALS OR FLUIDS SHOULD BE KEPT NEAR OR
ON APPLIANCE.

DO NOT SPRAY AEROSOLS IN THE VICINITY OF THIS APPLIANCE
WHILE IT IS IN OPERATION.

NOTE

WASH HOSES SHOULD NEVER BE USED ON THE APPLIANCE.

USE OF HOSES WILL VOID WARRANTY

5. CONVERSION INSTRUCTIONS

To convert from N.G. to L.P. Propane gas do the following:

1. Replace N.G. burner injectors with L.P.G. injectors (refer to table on this
page).

2. Adjust needle valve to achieve desired pilot flame size.

3. Disconnect regulator from gas supply line, disconnect natural gas regulator
from gas line reconnect LPG regulator on line..

4. Reset pressure test point on manifold.

5. Adjust burner aeration (if applicable).

Relevant required gas pressure for use in conversion

Natural 1.0 kPa W.G.
L.P. 2.5 kPa W.G.

AN AUTHORISED GAS FITTER MUST CARRY OUT GAS CONVERSION.
