TO KEATING FILE YOUR CLAIM AS ABOVE.

FIRST STEPS

POSITIONING

Keep appliance area free and clear of any
combustibles. Position the Miraclean® Griddle 6
inches (152mm) from any combustible material. A
minimum of 24 inches (610mm) should be provided at
the front of the Miraclean® Griddle for servicing and
proper operation. Air for combustion enters the
Miraclean® 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 Miraclean® Griddle is designed to be serviced
from the front with adequate clearance for air openings
into the combustion chamber servicing and operation.

MINIMUM CLEARANCE

Suitable for combustible floors.

VENTILATION

The Miraclean® Griddle must be installed in an area
providing adequate air supply and ventilation. Do not
obstruct the flow of combustion and ventilation air.
Proper ventilation is one of the important
considerations for efficient operation of the Miraclean®
Griddle. It should be installed so that the products of
combustion are removed efficiently 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 U.S.A. the ventilation systems
must conform to the ANSI/NFPA96 latest edition. “A
minimum of 18" (457mm) should be maintained
between the flue outlet and the lower edge of the
grease filters.” 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-B49.1 or the Propane Installation
Code, CAN/CGA-B149.2. Keating equipment is
designed and manufactured to operate only on the type
of gas specified by the user and indicated on the serial
plate located on the front panel. 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.

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. If you have a question
about gas pipe size call your local gas company.

CAUTION

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.

CAUTION

Pipe joint compounds that are used on threaded joints
of appliance piping shall be resistant to the action of
liquified petroleum gases. When using pipe joint
compound do not apply to the first two threads. Use
only very small amount and only on male threads. This
will prevent clogging of burner orifices 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.

1) The Miraclean® Griddle and 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.

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
(3.45 kPa).

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-

1.16, 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

Adequate means must be provided to
limit the movement of the appliance
without depending on the connector
and the quick-disconnect 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 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 flexible 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.

LEVELING

The Miraclean® Griddle will operate at its highest
efficiency 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
counterclockwise 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 find that your new Miraclean® Griddle has

superb heat transfer. The polished
trivalent chrome finish 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 difficult 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 finish 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
beneficial use of the Miraclean® Griddle.

The Miraclean® Griddle finds 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 fish.

It is necessary to understand that the

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