Do not connect the griddle to electrical supply until after gas connections are made.

OPERATION

WARNING

The griddle and its parts are hot. Use care when operating, cleaning the griddle.

BEFORE FIRST USE

Remove all packing material and protective plastic from the surfaces of the unit. Before leaving the factory, the griddle is coated with vegetable oil as a rust inhibitor. Remove this film when the griddle plate is being cleaned prior to its first cooking use. Heat the griddle to 200-300°F to loosen and melt the coating, then clean the surface by adding water or a non-corrosive, grease dissolving commercial cleaner, following the manufacturer's directions. Scrape the oil residue from the plate with a griddle scraper. Rinse thoroughly and wipe dry with a soft, clean cloth. Clean all accessories.

Season the griddle to avoid possible surface corrosion before first use, and after every cleaning. This will also help reduce the sticking of cooked food product. Heat griddle to a low temperature (300-350°F) and apply a small amount of cooking oil – about one ounce per square foot of surface. Use a soft lint-free cloth to spread the oil over the entire griddle surface to create a thin film. Wipe off any excess oil with a cloth. Repeat the procedure until the griddle has a slick, mirror-like finish.

CONTROLS - 900RX MODELS

pilot and burner sight holes thermostat knob VULCAN power switch pilot safety valve push button griddle shut-off valve (shown in ON position) Fig. 4

This model features an electric ignition system that is controlled by a momentary power switch. The power switch turns the electric ignition system off and on only and will only supply power to the igniters when held down in the ON position. The burners and pilots will continue to work with power switch in the OFF position until the gas supply to the unit is cut off or the griddle gas shut-off valve is turned to the OFF position (Fig. 6). In the event of a failure of the electronic ignition system, it is possible to ignite the pilots with an outside source (such as a lit taper, etc). See pilot lighting procedure.

There is one pilot and one safety valve for every two burners except on the 36" and 60" models. The 36" and 60" models have an odd number of main burners, therefore one of the sets of pilots and safety valves in these models will control only one main burner. The pilot burners are aligned with the pilot safety valve bush buttons. The pilot burners are inset 12" from the front panel. The pilots are monitored by thermocouples and pilot safety valves. If the pilot goes out, the safety valve will shut off the gas supply to the pilot and main burners.

Each 12" section of the griddle is independently controlled by a mechanical snap-action thermostatic valve. The thermostats have an operating range of 200 to 550 degrees. Once pilots are lit, turning the thermostats to the desired setting is all that is required to put the unit into service.

Each 12" griddle section may be turned off independently by setting the corresponding thermostat to the OFF position. You may also leave all thermostats set at the desired settings and turn all sections off at once by turning the griddle shut-off valve to the OFF position (Fig. 6). This will turn off the gas supply to the pilots and thermostats for all sections. Turning the griddle shut-off valve to the ON position (Fig. 5) and relighting the pilots at the beginning of the next cooking shift will be required to put the unit back in service. See pilot lighting procedure.

This model features a standing pilot that must be manually lit with an outside ignition source (such as a lit taper, etc). The pilot is monitored by a thermocouple and pilot safety valve. If the pilot goes out, the safety valve will shut off the gas supply to the pilot and main burners. There is one pilot and one safety valve for every two burners except on the 36" and 60" models. The 36" and 60" models have an odd number of main burners, therefore one of the sets of pilots and safety valves in these models will control only one main burner. The pilot burners are aligned with the safety valve bush buttons. The pilot burners are inset 12" from the front panel. See pilot lighting procedure.

Each 12" section of the griddle is independently controlled by a mechanical snap-action thermostatic valve. The thermostats have an operating range of 200 to 550 degrees. If the pilots are lit, turning the thermostats to the desired setting is all that is required to put the unit into service.

CONTROLS - VMG AND AGM MODELS

VULCAN burner control dial Pilot and burner sight holes Fig. 8 pilot adjustment screw

The model is equipped with standing pilots. Gas will flow from the pilots as soon as the main gas supply to the unit is turned on. The pilots are lit with the use of an outside ignition source (such as a lit taper, etc). There is one pilot for every two burners except on the 36" and 60" models. The 36" and 60" models have an odd number of main burners; therefore, one of the sets of pilots in these models will control only one main burner. The pilots are inset 12" from the front panel. See pilot lighting procedure.

Each 12" section of the griddle is independently controlled by an infinite heat control valve. Once the pilots are lit, turning the burner control knob counterclockwise to the full ON position will light each burner. The burners will be in the full ON position when the knobs are turned all the way to the left (Fig. 10). The burners will be in the OFF position when the knobs are turned clockwise until they stop (Fig. 9). The height of the burner flame and cooking plate temperature can be adjusted by turning the burner control knobs while viewing burners through the burner sight holes.

USING THE GRIDDLE

To preheat, turn the burners on about 20-25 minutes before cooking.

A uniform and systematic approach to loading the griddle will produce the most consistent product results.

The griddle plate is steel, but the surface is relatively soft and can be scored or dented by careless use of a spatula or scraper. Be careful not to dent, scratch, or gouge the plate surface. Do not try to knock off loose food that may be on the spatula by tapping the corner or the edge of the spatula on the griddle surface.

ZONE COOKING

This griddle features a tubular U-shaped burner in 12" sections, each controlled by independent thermostats (900RX, MSA, and ASA models) or manual valves (AGM/VMG models). Each 12" section is a separate cooking zone and allows cooking a wide variety of products over a single griddle plate. The chart below is a suggested usage of zone cooking.

When zone cooking, it is suggested that you start with your lowest temperature setting at either side of the griddle, increasing the zone temperature as you move up the zone line. These zone cooking guidelines will vary depending on product temperatures, size and shape. This guide should be adjusted to suit your product and operational cooking preference.

It is recommended to avoid using ice to rapidly cool the griddle surface temperature. Doing so could result in thermal shock and damage to the cooking surface.

CLEANING THE GRIDDLE

Empty the grease drawer as needed and regularly clean at least once daily.

Clean the griddle regularly. A clean griddle always looks better, lasts longer and performs better. To produce evenly cooked, perfectly browned griddle products keep the griddle plate clean and free of carbonized grease. Carbonized grease on the surface hinders the transfer of heat from the griddle surface to the food, resulting in spotty browning and loss of cooking efficiency. Carbonized grease tends to cling to griddle foods, giving them a highly unsatisfactory and unappetizing appearance.

To keep the griddle clean and operating at peak efficiency, follow these procedures:

AFTER EACH USE

Clean the griddle cooking surface accordingly to the type of surface on your model. See the specific cleaning instructions by cooking surface finish. Empty the grease drawer throughout the day as needed.

ONCE PER DAY

Thoroughly clean the griddle back splash, sides and front. Do not hit the backsplash with a spatula or any other tool. This may create a gap between the splash and griddle plate that is hard to clean. Remove, empty and wash the grease drawer in the same manner as an ordinary cooking utensil.

ONCE PER WEEK

Clean the griddle surface thoroughly per the instructions for the surface finish of your particular model. After cleaning the plate, the griddle should be seasoned according to the instructions in this manual.

Clean stainless steel surfaces with a damp cloth and polish with a soft dry cloth. To remove discoloration, use a griddle cleaner.

If the griddle usage is very high, consider conducting this weekly cleaning procedure more than once per week.

CLEANING THE STANDARD STEEL GRIDDLE PLATE COOKING SURFACE

AFTER EACH USE

Clean the griddle cooking surface regularly with a griddle scraper during the work shift.

ONCE PER DAY

Turn the griddle off and allow it to cool down between 275^ F- 300^ F, apply room temperature water and clean it with a griddle scraper.

ONCE PER WEEK

Clean the griddle surface thoroughly. Use a griddle brick, screen, or Scotch Bright™ pad on the surface as necessary. Rub with the grain of the metal while the griddle is still warm (not hot). A detergent may be used on the plate surface to help clean it, but be sure

the detergent is thoroughly removed by flushing with clear water. After cleaning, reseason the cooking surface according to the instructions in this manual. If the griddle usage is very high, consider conducting this weekly cleaning procedure more than once per week.

CLEANING THE OPTIONAL CHROME GRIDDLE PLATE COOKING SURFACE

AFTER EACH USE

Clean the griddle cooking surface regularly with a palmetto brush and a bladed griddle scraper during the work shift. Never use an abrasive scouring pad or griddle brick on a chrome plate surface. The chrome surface can be damaged by careless use of a spatula or scraper.

ONCE PER DAY

Clean chrome surfaces with a damp cloth and polish with a soft dry cloth.

ONCE PER WEEK

If the chrome plate has become carbonized or blackened, use a non-abrasive, non-silicate cleaner such as Bon Ami®. Be sure the cleaning agent is thoroughly removed by flushing with clear water. Wipe with a damp cloth and polish with a soft dry cloth. After cleaning, reseason the cooking surface according to the instructions in this manual.

CLEANING THE OPTIONAL RAPID RECOVERY™ COMPOSITE GRIDDLE PLATE COOKING SURFACE

The Rapid Recovery ^™ griddle plate is a composite material which is engineered to provide a high heat transfer rate to the food. The top surface is stainless steel and can be scored or dented by careless use of a spatula or scraper.

AFTER EACH USE

Clean the griddle cooking surface regularly with Nemco Easy Grill Scraper ^™ or similar type of griddle scraper during the work shift.

ONCE PER DAY

Turn the griddle off and allow it to cool down between 275^ F- 300^ F, apply room temperature water and clean it with a griddle scraper.

ONCE PER WEEK

Clean the griddle surface thoroughly with water, Scotch-Brite ^TM Quick Clean Griddle System or Ecolab Grease Express ^TM High-Temp Grill Cleaner. Be sure the cleaning agent is thoroughly removed by flushing with clear water. After cleaning, reseason the cooking surface according to the instructions in this manual.

If the griddle usage is very high, consider conducting this weekly cleaning procedure more than once per week.

Do not use a brick or griddle stone for cleaning.

Do not use chlorine sanitizer in contact with griddle. Contact can cause discoloration, corrosion and permanent damage.

Do not use cleaning agents including Sodium Hydroxide, which is common in household oven cleaners.

ADJUSTMENTS

CALIBRATION-900RX AND MSA MODELS

1. Each thermostat controls a 12" zone of the griddle. Using a Surface Probe temperature measurement device, observe the temperatures at the center points of the cooking zones. These points are located by starting 6" from the side splash (left or right) and every 12" across the width of the griddle, with all points located 12" back from the front edge of the griddle plate.

NOTE: Use of infrared thermometers is not recommended. These devices are highly sensitive to surface color (clean or dirty), angle of reading and distance from the unit.

1. Set thermostats to 350^ F and allow to stabilize, allowing the burner to cycle ON and OFF at least two times.
2. Watch for burner to cycle OFF, then measure the temperature for that zone. The temperature should be 350^ F ±15^ F. If not, continue to Step 4.

4.

a. Carefully loosen the knob set screw. DO NOT allow the knob to turn. Carefully remove the knob from the thermostat shaft, exposing the temperature dial.
b. Loosen screws on the temperature dial and adjust to that the temperature indicated by the knob arrow matches the griddle plate temperature reading. Knob will have to be placed back on the shaft to verify adjustment.

IMPORTANT: NEVER ADJUST THE SCREW IN THE CENTER OF THE THERMOSTAT SHAFT. This will ruin the factory calibration; the thermostat will no longer operate properly and will need to be replaced.

1. Once calibration is achieved, tighten the temperature dial screws and knob set screws.

LEVELING

The griddle must be level (side-to-side and front-to-back) during operation to ensure proper performance. Improper leveling can result in uneven temperature distribution, cold spots, and possibly damage electrical components.

1. Place a level on the griddle.
2. Adjust legs by turning the bullet feet at the bottom of each leg. Using pliers or a crescent wrench, turn the feet counterclockwise to increase height, and clockwise to decrease height until leveling is achieved. Do not extend the legs more than 1-3/4".

PILOT ADJUSTMENT

Using a flathead screwdriver, turn the slotted hex-head pilot adjustment screw clockwise to decrease the flame, and counterclockwise to increase the flame. MSA, ASA, & 900RX griddles require removal of the front panel to adjust the pilot. AGM/VMG griddles have a pilot adjustment cutout between knobs. See Fig. 14.

SHUTDOWN OF GRIDDLE WITH ELECTRIC IGNITION SYSTEM - 900RX MODELS

1. Turn thermostats to the OFF position to cut off burners or turn griddle shut-off valve to the OFF position.
2. Turning the griddle shut-off valve to the OFF position will turn the gas off to all thermostats and pilots. The pilots will have to be relit when restarting the griddle.
3. The pilots will remain lit and monitored by the safety valve as long as the griddle shut-off valve is left in the ON position.

SHUTDOWN OF GRIDDLE - MSA & ASA MODELS

1. Turn thermostats to the OFF position to cut off burners.
2. The pilots will remain lit and monitored by the safety valve as long as the main gas supply is on.

SHUTDOWN OF GRIDDLE WITH STANDING PILOT SYSTEM – VMG & AGM MODELS

1. Turn burner control knobs to the OFF position to cut off burners.
2. The pilots will remain lit as long as the main gas supply is on.

EXTENDED SHUTDOWN - ALL MODELS

1. Turn the griddle shut-off valve and/or the main gas supply valve to the OFF position.
2. Unplug the griddle electrical supply cord (if applicable).
3. Apply a heavy coat of vegetable oil over the griddle plate to inhibit rust.
