When the unit is installed in its operating location, level
the unit by adjusting the leveling legs. Use a spirit level
across the front, rear and sides of each unit.
Note: The griddle plate may not rest evenly on the unit
body if the unit is not properly leveled.
11. Each thermostat controls one zone burner through a
combination dual solenoid/pressure regulator valve,
complete with a pressure test spigot. The gas pressure
on each combination valve must be checked when the
unit is installed
to ensure that the gas pressure is the same as specified on
the Serial/Rating plate. For access to the pressure test
spigots, turn the main power switch and all zone power
switches to the "OFF" position as a safety precaution, and
hinge the lower front panel downwards. Pressure test
spigots are located at the rear of each combination valve,
including pilot combination valves. When your manometer is connected to the first combination valve for
test, turn the manual shut off valve, located under the unit,
to the open position (valve handle in line with piping).
Turn the main power switch to "ON" and turn all zone
power switches to "ON". All thermostat dials should be
set to approximately 350°F (182°C). When all burners are
operating, check the reading on the manometer. If not in
accordance with the pressure specified on the
Serial/Rating Plate, adjust the combination valve regula tor
accordingly. When satisfied with the manometer reading,
turn the main power switch to "OFF", remove the
manometer test tube and recap the test spigot. Repeat this
operation on each combination valve until each pressure
regulator is set correctly. Turn each thermostat, zone
power switch and main power switch to "OFF".
NOTE: Make certain no electrical connections have been
disturbed before replacing front panels.

VENTILATION
The unit must be installed in a location in which the
facilities for ventilation permit satisfactory combustion of
gas and proper venting. Proper ventilation is imperative for
good operation of the appliance. The ideal method of
ventilating a gas unit is the use of a properly designed
ventilating canopy, which should extend at least 6" (152
mm) beyond all sides of the appliance (except against the
wall, if the canopy is a wall installation). This is usually
part of a mechanical exhaust system .
1. Appliances shall be located so as not to interfere with
proper circulation of air within the
OPERATING INSTRUCTIONS
LIGHTING INSTRUCTIONS
confined space. All gas burners require sufficient air to
operate.
2. Large objects should not be placed in front of the
appliance which might obstruct the air flow through the
front. Do not obstruct the flow of combustion and
ventilation air.
3. Do not permit fans to blow directly at the appliance, and
wherever possible, avoid open windows adjacent to the
appliance sides and back;
also wall type fans which create air cross-currents within
the room.
Wait 5 minutes, then turn the main power switch back to
"ON".
Adequate means must be provided to limit movement of the
appliance without depending on the connector and quick
disconnect device or associate piping. This can be
accomplished by attaching restraining chains/cables from
floor or rear wall to rear of unit.
On units equipped with casters, ensure that front casters are
in the locked position and that the movement restraint is
connected to the appliance.
During an electrical power interruption, turn power switch
to the "OFF" position. This unit cannot be made to operate
without electrical power.
1. First, make certain that all power switches and thermostat
switches are set to "OFF".
2. Connect electrical power cord to 120 volt supply.
3. Turn the gas shut-off valve to the "OPEN" position
(valve handle in line with piping).
4. Turn the main power switch to "ON", power switch green
indicator should illuminate. Wait until gas pilot, green
indicator illuminate.
NOTE: Should pilot ignition fail after a few minutes,
turn the main power switch to "OFF".
5. When the green indicators for their respective zones are
illuminated, turn the zone power switch for each zone
to "ON" and set the thermostats to the desired
temperature settings.
6. The amber burner indicators cycle with the ther mostat
operation.
SHUT DOWN INSTRUCTIONS
1. Turn all zone and power switches to "OFF" (thermostat
dial settings may be left at their set point if preferred)
at the end of daily operations.
2. For extended shut down, turn all zone power switches to
"OFF", turn main power switch to "OFF", close the
manual gas shut-off valve and unplug the electrical
cord set.
NOTE: Do not waste gas or abuse equipment by leaving
thermostats at a high temperature, if not required.
During idling periods, set ther mostats to a low
temperature setting. For example: 175° (79°C) to 200°F
(93°C), to keep griddle warm. Rest thermostats, as
required, for periods of heavy load.

ADJUSTMENTS
PILOT ADJUSTMENT
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 installa tion. 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.
A pilot adjustment valve is located in the line from each
pilot combination valve. Pilot adjustment is acces sible 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, 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.
Turning the small screw in the pilot adjusting valve
clockwise reduces the amount of gas provided to the
pilot(s). Turning the small screw counter-clockwise
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.
When the air shutter adjustments are complete on each
burner, re -tighten the air shutter screw so that the correct
setting is locked in place.
NOTE: Make certain no electrical connections have been
disturbed. Replace both panels and secure to body.
THERMOSTAT CALIBRATION
This griddle thermostat is a precision instrument. It is
carefully calibrated at the factory so that the dial setting
matches the actual griddle temperature. Field re -calibration
is seldom necessary and should not be attempted unless
considerable experience with cooking results prove that the
thermostat is not maintaining the set temperature properly.
To check calibration, use a test instrument with a flat
temperature sensing surface, which can be placed on the
griddle plate surface. Place the sensor in the center of the
zone being tested.
1. Turn the griddle "ON" and set the thermostat to 350°F
(176°C). Allow the griddle zone to achieve
temperature and thermostat to cycle at least 3 times.
Take a temperature reading at the time that this
thermostat cycles on for the third time.
MAIN BURNER AIR ADJUSTMENT
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.
2. If, when the thermostat indicates heating (amber
indicator illuminated), the surface tempera ture does not
exceed plus (+) or minus (-) 8°F (13°C) of the
thermostat set point, no re-calibration is necessary.
If the griddle plate surface temperature exceeds +/- 8°F
(13°C), it could indicate a defective thermostat or
sensor. The electronic thermostat is precisely calibrated
at the factory. Any work should be performed by a
qualified service technician.

MAINTENANCE AND CARE
Periodical inspections by your dealer or qualified service
agency are recommended to check temperatures,
adjustments and ensure moving parts are operative.
Whenever possible, avoid overheating idle equipment, as
this is the primary cause for increased service costs.
Always disconnect the power supply to appliance before
servicing. After servicing, ensure that all connectors are
suitably secured back in place.
SEASONING
Before being used for the first time, all griddle surfaces
must be carefully "broken in" or "seasoned".
1. Remove all factory applied protective materials by
washing with a hot mild detergent or soap solution.
Rinse and dry thoroughly.
2. Set the griddle thermostats to a low tempera ture, 150°F
(65°C)to 175°F (79°C) and allow griddle to operate for
thirty minutes.
3. Apply a thin coat of olive oil or other high grade, salt
free, cooking oil to the surface. Wipe away excess.
4. Allow oil to remain on the griddle surface for 5 minutes,
then wipe off.
5. Reset thermostat to a medium temperature, 275°F
(135°C) to 300°F (149°C), and apply a second thin
coat of oil. Wipe off excess after 5 minutes.
6. Reset thermostat to desire cooking temperature and apply
a final coat of oil. Wipe off excess after 3 minutes. The
griddle is now seasoned and ready for use.
NOTE: Griddle may be re-seasoned at any time by
thoroughly cleaning and following the above procedures.
Griddles should be re-seasoned prior to each day's
operation.
CLEANING
Griddle plates should be cleaned daily while still warm.
Remove carbonized grease and/or food residue with a
spatula.
When necessary, clean griddle surface thoroughly using a
fine griddle brick, or a liquid griddle cleaner (available
from your kitchen equipment dealer).
Polish the griddle surface to a bright finish. Wash griddle
surface, rinse and dry thoroughly. Re -season the griddle as
per the seasoning instructions.
* Avoid overheating the griddle as this may cause sticking
and grease carbonizing, resulting in a hard to clean
surface.
* Do not hit spatula on the griddle plate as this will nick the
surface.
* Empty the grease tray frequently to avoid over filling and
spill overs.
EXTERIOR CLEANING
Normal soil may be removed from stainless steel with a hot
detergent or soap solution. To remove grease that has baked
on, apply cleanser on the metal in the direction of the
polishing lines of the metal. Never rub in a circular
motion.
Soil and burned deposits which do not respond can usually
be removed by rubbing the surface with SCOTCH-BRITE
scouring pads or STAINLESS scouring pads. Do not use
ordinary steel wool.
Heat tint can be removed by a vigorous scouring in the
direction of the polish lines, using SCOTCH-BRITE
scouring pads or STAINLESS scouring pads in
combination with a powdered cleanser.
