INTRODUCTION
GOLDSTEIN GAS GRIDDLE & COMBINATION GRILL AND
SALAMANDER TOASTER
MODELS GPG-30, GPG-45,GPGDB-12-24-36-48, GPGDB/SA-24,36
GOLDSTEIN GRIDDLES 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 Griddle is factory adjusted can be seen on the rating
plate, located on the front Control Panel.
“THE EQUIPMENT MUST BE INSTALLED BY A
LICENSED GASFITTER
Note The appliance must be installed by an Authorised person and in accordance with
the regulations of the local Gas Authority AS5601/AG601 and any other authority
having jurisdiction.
IM027B2/p3

2. INSTALLATION INSTRUCTIONS
PRE-INSTALLATION OF THE GRIDDLE
1. Check that there is sufficient clearance between doors and passageways to
move equipment into the cooking area.
2. Remove banding and cardboard outer.
3. Lift off wooden base.
4. Push in legs and tap in with a hammer into tubes (If required mount on stand
(OPTIONAL)
INSTALLATION
(FOR AUTHORISED TECHNICIANS ONLY)
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. Never
make a direct connection between the unit and vent flue. Check there is sufficient
room between doors and other units to allow equipment to be moved into position.
Check the data plate to ensure that the appliance is suitable for the gas supply to
which it is to be connected and for information relative to gas input. Etc.
Follow these instructions carefully.
1. Set unit in correct position (ENSURE THERE IS A MIN 25mm REAR WALL
CLEARANCE FROM COMBUSTIBLE MATERIALS AND THAT THE UNIT IS
PLACED ON A FIRE PROOF BASE) and adjust feet using a spirit level,
checking from back to front and side to side.
2 Have a licensed gas fitter or our local gas company connect the appliance to the
mains pressure supply. The gas inlet connection can be seen in the appendix.
The appliance must be installed in accordance with rules of any authority having
jurisdiction. The governor supplied must be installed on the gas inlet to the
appliance. This is supplied as a loose item.
3. All equipment must be sitting level for proper operation and combustion where
plinth type installation is made, plinth height and front overhang must be 50 mm
minimum. Levelling can be made by the use of metal shims. For griddles where
adjustable legs are provided, levelling can be made easily due to the threaded
construction of the legs.
Licensed plumber should make connection to main gas line. Install a hand
shut-off valve in gas line to the appliance manifold.
NOTE: Models operating on LP Gas are not supplied with a governor because none is
required.

3. COMMISSIONING INSTRUCTIONS
OPERATION
(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 griddle plate, remove the protective coating on the
plate with solvent (e.g. mentholated spirits).
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”. The aeration of each Burner can be adjusted by altering the
position of the shutter on the entrance to the throat of the Burner. Note GPGD/SA has
an adjustable bolt on the bottom of the Burner
If the appliance cannot be adjusted correctly for satisfactory operation, the matter
should be referred to the manufacturer or the local gas supply authority.
Ensure that the pressure at the pressure test point on the manifold is as per the rating
plate or as per page – of this manual. If the pressure is not the same use a
screwdriver to adjust the pressure regulator (turning screw clockwise will increase the
pressure).
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).
Turn the griddle plate off and apply a coating of cooking oil to the whole griddle plate
surface. Failure to do this will cause the warranty to be void.
NOTE
WASH HOSES SHOULD NEVER BE USED ON THE APPLIANCE.
USE OF HOSES WILL VOID WARRANTY
NOTICE
PLEASE RETURN YOUR WARRANTY CARD
FAILURE TO DO SO WILL VOID
WARRANTY ON THE EQUIPMENT
IM027B2/p5

4. OPERATING INSTRUCTIONS
INSTALLING FRETS INTO THE GPGDSA
This procedure is to be followed after the unit has been mounted into desired position.
Note To avoid damage to frets only insert them into a row from the left hand side.
Note The first fret that you put into each row should be the far right hand fret. All
other frets follow, so that the frets are put into position from the right to the left.
Step 1 Turn fret onto its side with points facing to the right (refer Fig 1)>
Step 2 Holding the fret in your left hand move to below the left hand side of the
desired row (refer Fig 1)
Step 3 Lift fret up between the left hand burner and the side of the unit. Tilting fret
slightly, slide fret onto rails above burners, ensuring that the fret has the points
facing down (refer Fig 1).
Step 4Using your right and your left hand in conjunction, slide the fret to the right
hand side. The first fret that you put into each row should be the right hand fret,
which will be positioned above the space between the 2 far right burners. The
next fret put into the row should be positioned in the space to the left of the
previous fret. This should be repeated until the specified amount of frets are put
into each row. (Refer Fig.2).
Note Each fret should be located above the space between each burner:
For the GPGDSA-24 there will be 3 frets in each row.
For the GPGDSA-36 there will be 5 frets in each row.

8. CLEANING INSTRUCTIONS
CLEANING/MAINTENANCE OF GRIDDLE PLATE
Frequently during the cooking, clean griddle plate with scraper (this will prevent food
build up and will make the final daily cleaning of the griddle plate easier).
Use a mild cleaner, CAUSTIC cleaners ARE NOT TO BE USED, otherwise warranty
will be void.
Before daily cleaning of the griddle plate, cool the plate to no more than 60C. Cooling
can be accelerated using water applied with a brush or well wetted cloth whilst wearing
gloves. DO NOT pour quantities of water direct onto a hot griddle place, as scalding
may result.
Clean down plate at the end of each working day. Thoroughly wash all traces of
cleaner off griddle plate with lukewarm soapy water, then rinse again and again with
fresh water and wipe thoroughly.
NOTE Ensure to empty out the grease can regularly while cleaning griddle otherwise
grease can will overflow.
Let griddle plate run on high for a few minutes to completely dry the water from the
plate.
Using a basting brush, after plate is completely dry and cool, cover the plate with a thin
layer of cooking oil to maintain the shinny appearance of the plate.
When cleaning the stainless steel surface under NO circumstances should wool
brushes or scraping implements of common steel be used on the stainless steel
because ferrous particles can deposit on the stainless steel surface causing by their
oxidation, rust spots.
Scotchbrite can also be used but it is necessary to always rub the surfaces in the
direction of the stainless steel finish.
If the appliance is to remain inoperative for a certain period, cover the griddle plate with
a thin layer of cooking oil, note that it is advantageous to keep the room in which the
appliance is installed.
Note
IF CAUSTIC SODA BASED OVEN CLEANERS ARE USED WARRANTY IS
VOID.
