GRIDDLES MOUNTED ON STANDS WITH CASTERS

Griddles mounted on stands with casters must use a flexible connector (not supplied) that complies with the Standard for Connectors for Movable Gas Appliances

AN SI Z21.6 9 • C S A6.1 6 , and a quick -disconnect device

that complies with Gas Fuel, ANSI Z 2 1. 3 •CSA6.9. I n

addition, adequate means must be provided to limit movement of the appliance without depending on the connector and the quick-disconnect device (or its associated piping) to limit appliance movement. Attach the restraining device at the rear of the griddle as shown in Fig. 1.

Fig. 1

If disconnection of the restraint is necessary, turn off the gas supply before disconnecting. Reconnect the restraint prior to turning the gas supply on and returning the griddle to its installation position.

Casters are only supplied on a griddle stand. If the griddle is moved for any reason the griddle should be re-leveled (see LEVELING in this manual).

FLUE CONNECTIONS

Do not obstruct the flow of flue gases from the flue, located at the rear of the griddle. It is recommended that flue gases be ventilated to the outside of the building through a ventilation system installed by qualified personnel.

From the termination of the flue to the filters of the hood venting system, a minimum cle a r a n ce of 1 8” m ust be maintained.

Information on the construction and installation of ventilating hoods may be obtained from

the standard for “Vap o r Removal f rom Cooking Equipment”, NFPA No. 96 (latest ed it ion),

available from the National Fire Protection Association, Batterymarch Park, Quincy, MA

02269.

STANDS

The griddle has an optional 24” high b y 3 0 ” d e e p st a inless steel stand with casters. The two front casters lock. The stand includes a top shelf with marine edges style lip and a lower shelf.

GAS CONNECTIONS

Gas supply connections and any pipe joint compound must be resistant to the

action of propane gases.

Us e a ¾” NPT g as supply l in e for the griddle inlet, located at the rear of th e g riddle. All

flexible and semi-rigid gas supply lines must comply with the applicable ANSI standard. To ensure maximum operating efficiency this appliance must be connected with a gas supply line of solid pipe or a commercial type Flexible Connector with the net inside diameter (I.D.) as large as or larger than the gas pipe inlet on this appliance. Codes require that a gas shutoff valve must be installed in the gas line upstream of the griddle.

Prior to lighting, check all joints in the gas supply line for leaks.

Use soap and water solution. Do not use an open flame.

- 7 -

After checking for leaks all lines receiving gas should be fully purged to remove air.

TESTING THE GAS SUPPLY SYSTEM

When the gas supply pressure exceeds ½ psig (3.45 kPa), the griddle and its individual shutoff valve must be disconnected from the gas supply piping system.

When the gas supply pressure is ½ psig (3.45 kPa) or less, the griddle should be isolated from the gas supply system by closing its individual manual shutoff valve.

GAS PRESSURE REGULATOR INSTALLATION

A gas pressure regulator is supplied with the griddle and must be installed. Install the regulator as close to the griddle on the gas supply line as possible. Make sure that the arrow on the underside of the regulator is oriented in the direction of gas flow to the griddle (Fig. 2) and the regulator is positioned with the vent plug and adjustment screw upright (Fig. 3). Check and set the gas pressure after the regulator is installed. The pressure should be set fo r 4” water column (W.C.) for natural g a s and 10” W .C. f or propane gas while all burners are on. It is recommended that a trained gas service technician with the necessary tools, instruments and skills perform the installation of the griddle and gas pressure regulator.

Fig. 2

Fig. 3

The supply pressure (upstream of the regulator) should be 7-9” W.C. for na t ural gas and 11-12” W .C. f or propane gas. At no time s houl d the g riddle be connecte d to supply pressure greater than ½ psig (3.45 kPa) or 14” W. C.

ELECTRICAL CONNECTIONS – 900RX MODELS

Electrical and grounding connections must comply with the applicable portions of the National Electrical Code and/or other local electrical codes.

Disconnect the electrical power to the griddle and follow lockout / tagout procedures.

Appliances equipped with a flexible electric supply cord are provided with a three-prong grounding plug. It is imperative that this plug be connected into a properly grounded three-prong receptacle. If the receptacle is not the proper grounding type, contact an electrician. Do not remove the grounding prong from this plug.

Power supply for electric ignition is 120 volts, 1 amp, 50/60 Hertz, 1 phase. Do not connect the griddle to electrical supply until after gas connections are made.

OPERATION

The griddle and its parts are hot. Use care when operating, cleaning or servicing 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-corrosi ve, gr e ase dissol ving 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.

SEASONING THE GRIDDLE

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.

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 m a in 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 f ront panel. The pilots are monitored by ther mocouples and pilot

safety valves. If the pilot goes out, the safety valve will shut-off the gas supply to the pilot and main burners.

Ea c h 12” s ect i o n 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.

Ea c h 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.

CONTROLS – AGM MODELS

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” an d 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” f r om the fr ont panel. See pilot lighting procedure.

Ea c h 12” s e c t ion o f the griddle is independently controlled b y an inf inite h eat c o n tr o l

valve. Once the pilots are lit, turning the burner control knob 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 full OFF position when the knobs are turned all the way to the right (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.

PILOT LIGHTING PROCEDURE – 900RX MODELS

1. Turn the griddle shut-off valve to the OFF position (See Fig.6 on page 9). Wait 5 minutes to allow any gas that may have accumulated in the burner compartment to escape.

2. Turn the griddle shut-off valve to the ON position (See Fig. 5 on page 9).

3. Push and hold the power switch in the ON position. The switch will illuminate and you will hear a “clicking” sound.

4. While continuing to hold the power switch in the ON position, depress and hold the red button on the pilot safety valve while the electric igniters light the corresponding pilots. You will have to monitor the pilot burners through the pilot sight holes. The pilot burners are aligned with the red buttons on the pilot safety valves. The pilot burners are inset 12” from the front of the unit.

5. Watch for the pilot burners to ignite. When the gas at the pilot has been burning for about 45 seconds, release the corresponding red button on the pilot safety valve. If the pilot does not remain lit, repeat the procedure allowing more time before releasing the button. The amount of time necessary to hold the safety valve button will increase at the initial installation of the unit and if the main gas supply has been turned off for a long period of time. It may be necessary to adjust the pilot valve to increase gas to the pilot.

6. Repeat steps until all pilots are lit.

7. The pilot burners can be lit manually in the event of a failure of the electronic ignition system. If this happens, repeat steps 1-5 without holding the power switch in the ON position. You will have to reach under the front of the unit and through the pilot cutout to ignite the pilots with an outside ignition source (such as a lit taper, etc.) while again depressing the corresponding red button.

8. If after completing steps 1 – 7 and the pilot does not light, turn the griddle shut-off valve to the OFF position (See Fig. 6 on page 9) and contact an authorized service contractor.

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-s haped burner in 12” sections, each controlled by independent thermostats (900RX, MSA and ASA models) or manual valves (AGM models). Each 12” section i s 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.
