6.  ‘LOW’ flame can be achieved by depressing 

and rotating the gas control knob fully anti-
clockwise. 

 

Using the Griddle 

1.  Light the pilot burners as shown above. 
2.  Turn the gas controls to the ‘FULL’ flame position.  

If starting from a cold start, allow the griddle 
plate to preheat for 10 minutes before using. 

3.  Place the product to be cooked onto the 

griddle plate. 

4.  For intermediate heat, position the gas control 

knob between the ‘HIGH’ and ‘LOW’ positions to 
achieve the desired heat. 

5.  During idle periods, the burners can be turned 

down to maintain an appropriate griddle plate  
temperature or the gas controls can be set to 
the ‘PILOT’ position as required. 

 

Using the Toaster 

1.  Light the pilot burners as shown above. 
2.  If starting from cold, set the burners to the ‘FULL’ 

flame position and allow 5 minutes preheat 
before commencing toasting. 

3.  Adjust the rack position to the 

desired height. 

4.  Place the product on the rack 

to toast. 

5.  Best toasting results are 

achieved using the shaded 
area shown on the diagram 
opposite. 

6.  With the main burners alight, the individually  

controlled burners can be operated to suit food  
quantity requirements. 

7.  Each burner is operated by an ‘OFF’ / ‘PILOT’ / 

‘HIGH’ / ‘LOW’ gas control.  The ‘HIGH’ position is 
recommended for most grilling, cheese melting 
functions and the ‘LOW’ position for a reduced 
heat setting.

exterior surfaces of the range with hot water, a 
detergent solution and a soft scrubbing brush. 

4.  Brush the griddle surface with a soft bristled 

brush.  Any carbon deposits should be removed 
using the supplied scraper tool followed by 
wiping with a cloth to prevent accumulation of 
food deposits. 

5.  Clean the control panel with a damp cloth 

lightly moistened with a solution of mild  
detergent and water.  Wipe dry with a clean dry 
cloth. 

6.  Dry the griddle toaster thoroughly with a dry 

cloth and polish with a soft dry cloth.

Ensure that protective gloves are worn during the 

cleaning process. 



DO NOT use harsh abrasive detergents, strong  

solvents or caustic detergents as they will dam-
age the griddle toaster and burners. 



DO NOT use water on the griddle plate while it is 
still hot as warping may occur.  Allow these items 
to cool and remove for cleaning. 

Part 5  Cleaning and Maintenance 

General 



To achieve the best results cleaning must be 
regular and thorough and all controls and 
mechanical parts checked and adjusted 
periodically by a qualified service person. 



If any small faults occur, have them attended to 
promptly.  Don't wait until they cause a 
complete breakdown.  It is recommended that 
the appliance is serviced every 6 months. 



Clean the griddle toaster regularly.  A clean  
appliance looks better, will last longer and will  
perform better.  Carbonised grease on the  

surface or on the griddle plate will hinder the 
transfer of heat from the cooking surface to the 
food.  This will result in loss of cooking efficiency. 

DO NOT use water on the griddle plate while this 
item is still hot as warping and cracking may occur.  
Allow the griddle plate to cool down before 
cleaning

 

NOTE: 



DO NOT use abrasive detergents, strong solvents 
or caustic detergents as they could corrode or  
damage the griddle toaster. 



In order to prevent the forming of rust on the  
griddle plate (Steel Plate), ensure that any 

 

detergent or cleaning material has been 

 

completely removed after each cleaning.  The 
appliance should be switched on briefly to  
ensure the griddle plate becomes dry.  Oil or 
grease should be spread over the griddle surface 
in order to form a thin protective greasy film.

 

 
To keep your griddle toaster clean and operating at 
peak efficiency, follow the procedures shown  
opposite:- 
 

After Each Use 

C

AUTION

 

Always turn off the gas at the main gas  
supply before cleaning. 
This appliance is not waterproof.  Do not use 
water jet spray to clean interior or 

 

exterior of this appliance. 

C

AUTION

 

Always ensure that an even pressure is  
applied over the whole surface of the 
scraper tool when using on the flat surface 
of the griddle toaster, to prevent scoring of 
the surface. 

 

NEVER bang the sharp edge of the scraper 
tool on the flat surface of the griddle as this 
will damage the finish and invalidate the 
warranty.
