ADJUSTMENTS  
NOTE: Each griddle has been factory tested and adjusted  
prior to shipment  It may be necessary to further adjust the  
unit as part of a proper installation  Such adjustments are the  
responsibility of the installer  Adjustments are not considered  
to be defects in material and workmanship, and they are not  
covered under the original equipment warranty  
Turning the small screw in the pilot adjusting valve clockwise  
reduces the amount of gas provided to the pilot(s)  Turning  
the small screw counterclockwise increases the gas provided  
to the pilot(s)  The gas should be adjusted to a 7/16 (11 mm)  
inch long flame, to ensure that the flame engulfs the top of  
the flame sensor  
Burners should always be warm when an adjustment to  
air shutters is made  To adjust air shutters, loosen the small  
screw along the side of the burner near the orifice  Lifting  
flames on the burner indicates too much air and this air  
shutter should be in a more closed position  Yellow tips on  
the flames indicate not enough air and the air shutter should  
be in a more open position  When the air shutter adjustments  
are complete on each burner, retighten the air shutter screw  
so that the correct setting is locked in place  
Pilot Adjustment  
A pilot adjustment valve is located in the line from each  
pilot combination valve  Pilot adjustment is accessible from  
behind the lower front panel  First remove the two screws  
securing the upper front panel to the body, in the upper  
right and left hand corners, and then slightly raise the panel  
to lift off  Remove to a safe area  Next, remove the two screws  
securing the lower front panel to the body, in the upper right  
and left hand corners and hinge the panel downwards

the griddle surface  
Stainless Steel  
Stainless steel should be cleaned using a mild detergent,  
a soft cloth and hot water  If it is necessary to use a non-  
metallic scouring pad, always rub in the direction of the grain  
in the metal to prevent scratching  Wash a small area at a  
time and rinse the washed area with a clean sponge dipped  
into a disinfectant and wipe dry with a soft clean cloth before  
it can dry  
  Remove the grease drawer, empty and wash thoroughly  
with soap & water  Replace  
Cleaning Instructions (For Heavy Build Up)  
NOTE: After using cleaners & grease cutter, re-season the  
griddle  
Use only stainless steel, wood or plastic tools to scrape  
off heavy deposits of grease or oil  Do not use ordinary  
steel scrapers or knives, as particles of iron may become  
embedded and rust  
Apply to a warm griddle for best results  
1  Using a traditional 64mm-76mm (2 1/2”-ꢀ”) scraper  
or spatula scrape the griddle surface (to remove food  
particles and oil residues) towards the grease trough  
using even back to front strokes  Deposit debris into the  
chute  
NEVER USE STEEL WOOL  
Griddles  
2  Apply griddle cleaner evenly over the griddle surface and  
let sit as directed  Follow the procedures on the label of  
the specific cleaning product

MAINTENANCE & CLEANING Continued  
Don’ts  
  Do not use the griddle as a hot top  A large pan or pot will  
trap heat and can cause the griddle plate to warp  
1  Do not use salt to clean the griddle surface  Salt is  
corrosive and can cause pitting of the griddle  
4  Do not overheat the griddle to preheat faster  Preheating  
only takes 15 – 20 minutes  
2  Do not allow metal utensils (Spatula, scraper, etc ) to  
nick and/or dent the surface of the griddle  The edges of  
these utensils are sharp and will create divots that oil can  
collect in and caramelize which will cause sticking  
SERVICING
