FIRST STEPS

POSITIONING

Keep appliance area free and clear of any combustibles. Position the Keating Miraclean® Griddle 6 inches (152mm) from any combustible material. A minimum of 24 inches (610mm) should be provided at the front of the Keating Miraclean® Griddle for servicing and proper operation. Air for combustion enters the griddle from the bottom of the cabinet and the bottom of the control panel.

DO NOT BLOCK BOTTOM OF MIRACLEAN ®

GRIDDLE CABINET. DO NOT OBSTRUCT FLUE.

Your Keating Miraclean® Griddle is designed to be serviced from the front with adequate clearance for air openings into the combustion chamber servicing and operation.

SUITABLE FOR NON– COMBUSTIBLE FLOORS

VENTILATION

The Miraclean® Griddle must be installed in an area providing adequate air supply and ventilation. Do not obstruct the fl ow of combustion and ventilation air. Proper ventilation is one of the important considerations for effi cient operation of the Miraclean®

Griddle. It should be installed so that the products of combustion are removed effi ciently without producing drafts that will interfere with proper burner operation. The area around the front and bottom of the Miraclean® Griddle must be kept clear and unobstructed. In the USA, the ventilation systems must conform to the ANSI/NFPA96 latest edition.

“A minimum of 18" (457mm) should be maintained between the fl ue outlet and the lower edge of the grease fi lters.” It is the responsibility of the owner and the local installer to comply with national and local codes.

NATIONAL CODE REQUIREMENT

The installation must conform with local codes, or in the absence of local codes, with the National

Fuel Gas code, ANSI Z223.1 or the Natural Gas

Installation Code, CAN/CGA-B149.1 or the Propane

Installation Code, CAN/CGA-B149.2. Flexible connectors must comply to ANSI Z221.69/CAN/CGA1.16.

Keating equipment is designed and manufactured to operate only on the type of gas specifi ed by the user and indicated on the serial plate located inside the door. The gas may be natural, propane or manufactured. The type of gas cannot be converted to another gas fuel by turning or engaging a switch.

NOTE: NOT FOR OUTDOOR INSTALLATION.

GAS CONNECTIONS AND PIPE SIZE

The Miraclean® Griddle requires a standard gas pipe size of 3/4 inch (19mm) I.D. connection. The size of the gas supply pipe is very important. If the pipe is too small you will have low gas pressure at the

Miraclean® Griddle manifold. Low gas pressure will cause slow recovery and/or delayed ignition, amongst other problems. If you have a question about gas pipe size, call your local gas company.

Before connecting new pipe to the Miraclean® Griddle the pipe must be blown out to remove all foreign particles. These particles in the controls or burners may cause improper or dangerous operating conditions.

Pipe joint compounds that are used on threaded joints of appliance piping shall be resistant to the action of liquefi ed petroleum gases (Loctite PST

56765). When using pipe joint compound do not apply to the fi rst two threads. Use only a very small amount and only on male threads. This will prevent clogging of burner orifi ces and the gas valve. Never use compound on female threads as it might be pushed into the gas valve.

Have your installer check for gas leaks using a soap and water solution before operating.

DO NOT USE AN OPEN FLAME TO CHECK FOR

GAS LEAKS.

WARNING

Do not use open flame to check for leaks.

its individual shut off valves must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of

1/2 psi (3.45kPa) (13.84 in WC). High pressure can damage the gas valve causing a hazardous

condition.

Excessive pressure introduced to the griddle may void the warranty.

GAS GRIDDLE - SERIES 2000

2. The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psi

LEVELING

NOTE: Line pressure must be kept below 10" (Nat),

13" (LP) during leak test to avoid damage to the gas valve.

The required gas pressure for proper operation of each

Miraclean Griddle® is 4" water column for natural gas and 10" water column for propane gas at the manifold.

If more than one gas unit is on the same supply line, you may require a larger line. Consult your local gas company to assure adequate volume and pressure.

Refer to serial plate for proper gas requirement for your particular model.

FLEXIBLE GAS CONNECTORS

AND QUICK DISCONNECT DEVICES

For an appliance equipped with casters:

The installation shall be made with a connector that complies with the Standard for Connectors for Movable

Gas Appliances, ANSI Z21.69 or the Standard for

Connectors for Moveable Gas Appliances, CAN/CGA-

6.16, and a quick disconnect device that complies with the Standard for Quick-Disconnect Devices for

Use With Gas Fuel, ANSI Z21.41 or the Standard for Quick Disconnect Devices for Use with Gas Fuel,

CAN1-6.9.

RESTRAINING DEVICES

NOTICE

Restraining devices required.

Adequate means must be provided to limit the movement of the appliance without depending on the connector and the quickdisconnect device or its associated piping to limit the appliance movement. Griddle installation on stands with caster, casters and jam nuts must be completely tightened.

The restraint means must be attached to the rear of the Miraclean® Griddle within 2" of the center line width and approximately 1-5/8" from the bottom of the cabinet back to allow the restraining bolt to be anchored to the cabinet back between the cabinet bottom and inner liner to ensure positive support to restrain Miraclean® Griddle movement and not depend on the fl exible gas connector, quick-disconnect or piping to limit the Miraclean® Griddle movement.

If disconnection of the restraint is necessary, it must be reconnected when the Miraclean®Griddle is returned to its originally installed position.

The Miraclean® Griddle will operate at its highest effi ciency when properly leveled. Place a level on the

Miraclean® Griddle plate from side to side. For griddles on legs, the bottom foot of the leg is adjustable. Turn counter clockwise to decrease height, or clockwise to increase height until level. For griddles on stands with casters, the casters are adjustable by loosening the jam nut. When the desired level is reached, tighten the jam nut. Adjustments of more than 3/4" are not recommended on any caster. The same procedure should be followed to level the Miraclean® Griddle from front to back.

COOKING WITH YOUR MIRACLEAN® GRIDDLE

You will fi nd that your new Miraclean® Griddle has superb heat transfer. The polished trivalent chrome fi nish of the Miraclean® reduces the emission of radiant heat. Radiant heat is measured by emissivity. The radiant heat of a perfect black body has an emissivity of 1. The radiant heat of a conventionally seasoned

Griddle plate is approximately .87. The radiant heat of the Miraclean® has an emissivity of .078.

You can prove this to yourself by holding your hand approximately 1/2" above the Miraclean® Griddle plate.

At this distance it is diffi cult to tell whether the Griddle plate is hot or not. It feels as though the Griddle plate is barely warm, but if you touch the plate, it will burn you.

The polished trivalent chrome fi nish on the Miraclean®

Griddle plate is a wonderful insulator. It prevents the radiant heat from leaving the griddle plate. It transfers conducted heat to the food being cooked more rapidly than other griddle plates, because the food is placed directly on the metal surface. It is the understanding of this rapid heat transfer that permits the practical and benefi cial use of the Miraclean® Griddle.

The Miraclean® Griddle fi nds an application in all sorts of griddle work, from cooking wheat cakes to scrambling eggs. We use these two products as illustrations because generally wheat cakes are cooked on a hot griddle. Eggs must be scrambled on a relatively cold griddle. Between these two extremes fall dozens of griddled items - everything from grilled frankfurters, grilled Italian sausage, grilled sausage patties, the entire range of steaks and chops and chicken and fi sh.

It is necessary to understand that the caramelization of the meat products being cooked takes place at a higher rate and at a lower griddle surface temperature because of the improved heat transfer of the

Miraclean® Griddle.

Eggs can not only be scrambled, but can be fried in any fashion. If the eggs are to be basted it is necessary to have a metal cover, and to spill or splash a

EGG COVER small amount of water under the cover so that the steam will baste the top of the eggs. Eggs require a very low temperature because generally you do not want the eggs to be browned on the bottom where they come in contact with the griddle plate. Approximately 250°F is ideal for scrambling or frying eggs.

There are several griddle tools.

A hamburger spatula is like the one pictured here. The hamburger must stick at least slightly to

HAMBURGER

SPATULA the griddle to hold its shape. If it does not stick it shrinks in diameter, and the center of the meat

GAS GRIDDLE - SERIES 2000 becomes thicker. It becomes more of a meat cake than a hamburger. Therefore, the hamburger spatula has a strong cutting edge.

An egg spatula is shown in this illustration. An egg spatula has a long very thin blade so that it can be slipped under the egg without damag-

EGG SPATULA ing it or breaking the yolk. This spatula can also be used for chopping the scrambled eggs so as they are turned they can be cooked to perfection without unnecessary browning.

This same spatula is used for omelettes.

The Miraclean® Griddle can be kept in perfect condition by using a razor blade griddle scraper to remove the fi lm that is deposited from the products that have been previously cooked. Eggs, being cooked at a lower temperature, require substantially no scraping; but meat and meat products cooked at a higher temperature, do

GRIDDLE

SCRAPER require scraping. Pancakes or wheat cakes which are cooked at a much higher temperature, do not require that the Griddle be scraped. It is merely brushed clean with the spatula.

The important thing about the satisfactory use of the

Miraclean® Griddle is to understand its rapid heat transfer at low temperatures, and to understand how to maintain the Griddle plate clean and shiny at all times.

If an accumulation builds up on the Miraclean®

Griddle, it is necessary only to wash it with a palmetto pot brush and cold water. As you pour water on the

Griddle and wash the Griddle with a palmetto brush, it will come clean and beautiful in but a few seconds. A scraper is used to completely remove any deposit left from previous products on the Griddle surface. Polish the Griddle so it looks new using KEATING Klenzer and a dry cloth. (See Cleaning Instructions)

1. Set the thermostat to the desired temperature and wait ten minutes for preheat.

The operating temperature should be from 10°F to 25°F lower than conventional griddles – at least start at lower temperatures.

You may be able to work the temperature up as you become accustomed to the more rapid cooking of the Miraclean® Griddle.

2. Cook as usual, but after each batch scrape the griddle in the work area completely clean, using the 4" wide scraper supplied by Keating. (This may be the only cleaning you will ever need.)

HIGH TEMPERATURE – Since the Miraclean® Griddle does not radiate heat (for all practical purposes) sometimes people turn the griddle all the way up to 400°F.

Eggs, bacon, hash browns and hamburgers will not cook on a very hot griddle. Use low temperatures and work your way up to the proper temperature.

DO cook around the thermostat sensing bulb.

DON'T cook directly over the thermostat sensing bulb.

CLEANING THE MIRACLEAN® GRIDDLE

The surface of the MIRACLEAN® Griddle is very durable and with proper care, following the procedures below, will last many years.

A sample of Keating Klenzer, Keating palmetto brush and a 4" scraper are included with each new griddle.

1. Scrape Miraclean®

surface.

BEST COOKING AREAS ON THE MIRACLEAN®

GRIDDLE

To use the best cooking areas, locate the inverted “V’s” on the front of the griddle cooking plate. Depending on your model you may have from one to six thermostats.

The “V’s” indicate where the thermostat sensing bulbs are located below the plate.

If you cook over the sensing bulb only you are drawing heat from that section; the thermostat calls for heat but since it has not dissipated in the other areas of the surface, you can overheat the griddle plate.

2. Clean your Miraclean®

Griddle while hot at

300°F to 350°F. Using a plastic pitcher, pour water ahead of a palmetto pot brush.

Then scrub the griddle clean with the pot brush sweeping the water into

the drain trough.



CONDITIONING THE MIRACLEAN®

GRIDDLE PLATE

The Miraclean® Griddle plate has been “seasoned” at the factory. The Miraclean® surface when heated creates a thin layer of chrome oxide which acts as a releasing agent for food product. You may feel that you need to recondition your griddle surface.

1. Follow cleaning instructions on page 6.

2. Heat the Miraclean® to 400°F for one hour.

3. Lower thermostat to 350°F, allowing the Miraclean® to cool to about 350°F, as is evident when griddle cycles on or surface thermometer indicates correct temperature.

4. Lightly coat the Miraclean® surface with griddle oil.

NOTE: Despite the food releasing properties, the chrome surface is not a true “non-stick” surface. For best cooking results and product appearance, use griddle oil for products that require the surface to be conditioned.

SERVICE

Servicing should only be performed by qualifi ed & licensed service companies.

GAS VALVE REGULATOR ADJUSTMENT

Recommended gas pressure at manifold

(4.0" W.C. Natural gas 10.0" W.C. Propane gas)

Adjustment of the gas valve pressure regulator is not normally necessary since it has been preset at the factory. During installation, the gas pressure should be checked at each gas valve with all burners operating.

Adjustment may be accomplished as follows:

NOTE: This adjustment must be performed by a qualifi ed technician.

1. Locate the gas valves.

2. With the griddle turned off, connect the monometer to the pressure tap on the gas valve to be tested.

3. Turn the unit on and take the reading after all the burners have ignited.

4. Make the necessary adjustments by removing the screw cap on the pressure regulator cover exposing the adjustment screw (clockwise will increase the pressure, counterclockwise will decrease the pressure).

Always check the screw cap on the pressure tap for leaks after it has been removed and replaced.

GAS VALVE REMOVAL AND REPLACEMENT

Disconnect the griddle from the gas supply.

1. Lower the control panel. Remove the control panel surround and upper heat shield.

2. Remove the three wires connected to the gas valve.

3. Disconnect the pilot and burner feed from the front of the gas valve.

4. Access the pipe union at the rear of the gas valve either from the front of the griddle or remove the back of the cabinet and loosen the union.

5. Remove two nuts on the rear of the gas manifold and pull the gas manifold forward.

6. Remove the gas valve and transfer the pipe and fi ttings to the new gas valve. Transfer the pressure tap to the new gas valve.

7. Replace the gas valve by reversing the above steps.

Always check for leaks at all joints and connections using a soap solution mixed with water.

DO NOT USE AN OPEN FLAME TO CHECK FOR GAS LEAKS

Double check the wire connections to the gas valve; improper connection could damage the gas valve.

12 | keatingofchicago.com

ON/OFF SWITCH REMOVAL AND REPLACEMENT

1. Lower the control panel by removing the screws.

2. Disconnect the wires on the switch and remove switch.

3. Snap the new switch into place and reconnect all wires.

4. Return the control panel to its normal position.

THERMOSTAT REMOVAL AND REPLACEMENT

1. Lower the control panel by removing the mounting screws.

2. Locate the bulb end of the thermostat and, using a wrench, loosen the front and rear bolts holding the thermostat bulb and shield in place.

3. Slide the thermostat bulb assembly towards you and remove it from under the griddle plate.

4. Remove the knob and the screws from the thermostat dial plate on the control panel.

5. Remove the body of the thermostat.

6. Install the new thermostat in the control panel, replace the dial plate.

7. Slide the thermostat bulb assembly into the channel until it reaches the stop.

8. Make sure that the thermostat capillary and bulb are completely protected by the shield, except for 1” at the tip of the thermostat bulb. (See Note 1).

9. Make sure that the thermostat shield extends to the front edge of the plate, and that the capillary goes through the formed end of the shield. (See Note 2).

10. Make sure that the bolts which hold the thermostat bulb and shield in place do not touch the thermostat bulb. (See Note 3).

Tighten bolts 1/4 turn past fi nger tight bulb to be snug against the bottom of the plate.

DO NOT OVERTIGHTEN THE BOLTS ON THE

THERMOSTAT SHIELD OR THEY WILL CRUSH THE

THERMOSTAT BULB.

11. Close the control panel and replace the panel mounting screws.

NOTE: IF REPLACING PUSH-ON TERMINAL STYLE.

Before installing thermostat into control panel, you must unscrew the two brass terminal screws and install the new ring terminal wire connectors. Prior to connecting these wires, the existing push-on terminal must be cut off and ring terminals installed on them.

Make sure that the terminals are secured down.

12. Calibrate the thermostat using an accurate griddle thermometer. Locate the thermometer over the thermostat bulb (shown by the "V" on the front of the griddle plate) about half way toward the back of the plate. Calibrate to the cooking temperature you will be setting on the thermostat.

THERMOSTAT BULB PLACEMENT DETAIL

MILLIVOLT CHECK (FOR QUALIFIED SERVICE

TECHNICIANS ONLY)

The millivolt valve is a thermopile self-powered combination gas control. Before checking the millivolt system, the following operations should be performed and observations made:

1. A genuine Keating millivolt thermostat should be used for millivolt operation.

2. The thermostat leads and all wire connections should be cleaned and tightened to eliminate all unnecessary resistance.

3. If pilot will not remain lit when gas valve knob is released, check automatic pilot.

NOTE: The millivolt system and individual components may be checked with a millivolt meter having a 1-1000MV range.

Conduct each check below by connecting meter test leads to terminals as indicated. All readings are closed circuit.

GAS GRIDDLE - SERIES 2000

(REFER TO CHART BELOW)

A. BURNER COIL CHECK

(“A” Reading. Thermostat contacts CLOSED - Gas Valve knob “ON”. Main burner should come ON.)

1. If the reading is more than 100 millivolts and the automatic valve still does not come one, replace the valve.

2. If the closed circuit reading (“A” reading) is less than 100 millivolts, determine cause for low reading and proceed as follows:

B. THERMOPILE OUTPUT CHECK

(“B” Reading. Thermostat contacts OPEN - Main burner

OFF.)

1. Thermopile system - 325 millivolts minimum. If the

minimum millivolt reading is not obtainable,

readjust thermopile for maximum millivolt output.

If millivolt reading is still below minimum specifi ed,

replace thermopile.

C. THERMOSTAT RESISTANCE CHECK

(“C” Reading. Thermostat contacts CLOSED - Gas valve knob “ON”. Main burner should be ON.)

1. If the “C” reading is above 80 millivolts, the resistance in the system is excessive and must be reduced. To correct: a. Clean and tighten thermostat leads and

connections.

b. Shorten or replace thermostat lead wires.

c. Cycle thermostat rapidly (manually turn dial)

to clean contacts.

D. AUTOMATIC PILOT DROPOUT CHECK

1. Hold gas valve knob depressed in pilot position

until maximum output is observed. Then extinguish

pilot and observe meter.

2. Dropout of automatic pilot magnet (sound should

be audible) should occur between 120 millivolts

and 30 millivolts. If dropout occurs outside these

limits, change the valve.
