IMPORTANT SAFEGUARDS & SAFETY INSTRUCTIONS
When using gas cooking equipment, basic safety precautions should always be
followed, including the following:
The Griddle outside surfaces may become HOT after use. Use caution when touching the unit.
· Never directly touch the burners or cooking grates while the Griddle is on.
· Always turn off the unit when not in use, servicing or adjusting any parts or attachments, and before
cleaning.
· Never leave the Griddle on overnight.
· Do not operate any equipment with a damaged or leaking gas line, ignitor or valves or if the unit is dropped
or damaged in any manner. Call for service.
· The use of attachments not recommended or sold by the manufacturer may cause fire, injury or even death.
· Do not use outdoors.
· Do not use this equipment for any use other than the use intended by the manufacturer.
· Never use the Griddle as a heating source
· The Griddle does not contain any user-serviceable parts. Dealers or recommended qualified technicians
should carry out repairs. Do not remove any components or service panels on this product.
· Never bypass, alter, modify or attach any unauthorized parts to this equipment. Doing so may create
hazards and will void warranty
· Vender takes every care to ensure that all products are safe. Steel cutting procedures used to manufacture
these items result in sharp edges. These sharp edges are removed to the best of our ability; however, we
insist the operator take care when in contact with this piece of equipment.
· Always keep hands, hair and clothing away from heating source.
· Allow the Griddle to cool down after use and before dismantling for cleaning; the unit will be too hot to handle
immediately after use.

Operating Instructions
Operating the Griddle - Pilot Lighting Instructions for MANUALLY CONTROLLED Griddles
Before operating Griddle, it should be checked to see that it is sitting level. Adjust the feet to level the Griddle.
Be sure the catch tray has been properly placed.
The pilot light on the appliance have been set at the factory. Each burner has a pilot light.
1. Make sure all knobs are in the “OFF” position.
2. The main gas valve should be “CLOSED/OFF” for five (5) minutes prior to lighting pilots to clear any
existing gas. (Main gas valve is supplied by others.)
3. Turn “ON/OPEN” the main gas valve to the unit.
4. Light and hold an ignition source (match) at the pilots. When the flame is established, remove the
ignition source. Repeat this step for each burner as each burner has its own individual pilot.
The pilot can be reached through the holes in the front of the unit.
5, Adjust the pilot valve, make sure the pilot flame at 1/2 inch height.
6. Turn each burner knob “ON”. If the burners do not ignite promptly, turn the knobs “OFF”. From the
opening in the front panel, use a screwdriver and turn the pilot valve screw counterclockwise which
will increase the flame height and repeat step 4.
If the pilot flame appears larger than necessary, turn it down and reset burner ignition. The pilot
flames should be as small as possible but large enough to guarantee reliable ignition of the burners
when the knobs are turned to “ON”. The holes located in the front panel are pilot valve adjustments.
Use a screwdriver to turn the valve to adjust the flame height to your desired level.
All burners are lit from constantly burning pilots. Turning the valve to the desired
flame height is all that is required to put the unit in service

9
Operating Instructions
Igniting the Burner
To ignite the burner, turn knob to the “ON” position. Then back off to the desired flame level. The
range of adjustment is virtually infinite between “ON” and “OFF”.
The space between the legs at the bottom admits combustion air. DO NOT BLOCK THIS SPACE.
All burners are lit from constantly burning pilots. Turning the valve to the desired flame height 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 unit’s
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 ventilating system. Otherwise, a subnormal atmospheric pressure will occur, affecting
operation and causing undesirable working conditions.
A properly designed and installed hood will act as the heart of the ventilating system for the room or area in
which the unit is installed, and will leave the unit independent of changing draft conditions.
NOTE: It may be necessary to adjust the balance of gas, volume and air supply to each burner. This must be
done by an authorized service technician.
Seasoning the Griddle
Heat to low temperature (300 - 350 F/150-180C) and pour small amount of cooking oil to the griddle plate
(about one ounce (30cc) per square foot of surface). Spread the oil over the entire griddle surface with a cloth
to create a thin film. Wipe off any excess oil with a cloth. Repeat this procedure 2 to 3 times until the griddle
has a slick, mirror-like surface.
Operating the Griddle
Turn the burners on about 15-20 minutes before cooking for preheating. Set the knobs to the desired flame
height or temperature. Each valve controls the gas flow to the burner to bring that area of the unit up to the set
temperature.
If different temperature settings are to be used, adjoining areas should be set at progressively higher
temperatures using the lowest temperatures on the outside burners. A uniform and systematic approach to
the loading of the unit will produce the most consistent product results.
Shutdown burner
To turn 'OFF' the appliance completely, turn the gas control knob completely clockwise to the 'O' position, the
pilot burner will extinguish.

10
·DO NOT use any abrasive or flammable cleaning fluids.
·DO NOT hose down, immerse or pressure wash any part of the Griddle, excluding the catch tray.
·NEVER use a scrubber pad (on all exterior surfaces, except the griddle plate), steel wool or abrasive
material, or cleaners containing chlorine, iodine and ammonia or bromine chemicals as these will
deteriorate the stainless steel and shorten the life of the unit.
IF CLEANING ALL THE GRIDDLE’S SURFACES, THE MAIN GAS VALVE MUST BE
SWITCHED TO THE CLOSED POSITION. AFTER CLEANING, THE GAS LINE CAN BE
SWITCHED BACK TO THE OPEN POSITION. PLEASE FOLLOW THE LIGHTING
INSTRUCTIONS IN THIS MANUAL TO RELIGHT THE GRIDDLE’S PILOT LIGHTS AS
NEEDED.
RECOMMENDED CLEANING
It takes very little time and effort to keep the Griddle attractive and performing at top
efficiency. Wait until the griddle is cool after the unit has been turned off. Please follow the
cleaning steps below:

while the griddle is still warm. A mild soap may be used on the plate
surface to help clean it • Remove all soap and debris thoroughly; wipe
with a clean, damp cloth. • The plate should then be covered with a thin
film of oil to prevent rusting. Clean stainless surfaces with a damp cloth
and polish with a soft dry cloth. To remove discoloration, use a
nonabrasive cleaner. After each “weekly” cleaning, the griddle must be
seasoned again. If the griddle usage is very high, the “weekly” cleaning
procedures may be done more often than once a week.
