ASSURE THAT PROPANE GAS IS NOT PRESENT
EVEN THOUGH YOU DO NOT DETECT AN ODOR.
IF THERE IS ANY DOUBT, YOU SHOULD CALL
YOUR LOCAL PROPANE GAS SUPPLIER FOR
ASSISTANCE.
III OPERATING
LIGHTING
Lighting instructions are also listed on the lighting
instruction plate attached to the front of the air shield.
1. Turn the ON/OFF switch to the “OFF” position.
2. Turn gas valve knob to pilot position.
Figure 3-1
Millivolt Safety Pilot Valve
3. Depress and hold gas valve knob while repeatedly
pushing red button (Piezo spark ignitor) on control
panel until pilot flame is established. Allow pilot to
burn 90 seconds before releasing gas valve knob.
This will allow the thermopile to reach its maximum
millivolt and milliamp output.
NOTE: Allow pilot to burn one additional minute before
turning thermostat dial to desired position. Pilot flame
should be blue in color and high enough to envelop the
tip of the thermopile to activate the gas safety valve.
Figure 3-2
Piezo Spark Ignitor
4. Turn gas valve knob to “ON” position.
5. Turn ON/OFF switch to “ON” position.
6. Set thermostat dial to desired temperature. When
the griddle plate reaches the temperature setting the
main burners will extinguish.
DURING INITIAL INSTALLATION,
AFTER OVERNIGHT
SHUTDOWN, OR WHEN
RELIGHTING, AIR IN THE
SUPPLY LINE MAY MAKE IT
NECESSARY TO HOLD THE
GAS VALVE IN THE
DEPRESSED PILOT POSITION
FOR A LONGER THAN NORMAL
PERIOD OF TIME. WAIT FIVE
MINUTES BEFORE REPEATING
LIGHTING PROCEDURE TO ALLOW ANY GAS
WHICH MAY HAVE ACCUMULATED IN THE
BURNER COMPARTMENT TO ESCAPE.
NOTE: If you have difficulty lighting the pilot:
1. Place ON/OFF switch to the “OFF” position.
2. Wait five minutes before relighting.
3. Repeat Steps 2 - 6 of Lighting Instructions.
CONDITIONING THE
GRIDDLE
The MIRACLEAN® Griddle plate has been “seasoned”
at the factory. The chrome surface, when heated
creates a thin layer of chrome oxide which acts as a
releasing agent for food product. If you feel you need to
recondition, the following instruction should be
followed:

5
1. Follow cleaning instruction on page 7.
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
shortening.
COOKING
MIRACLEAN® Griddles are designed to provide
maximum production efficiency and deliver high quality
food products. Follow cooking procedures below for
your model.
1. Set the thermostat to the desired temperature and
wait ten minutes for preheat. Shown are
recommended cooking temperature guides:
NOTE: Because of the superior heating characteristics
and heat retention properties found in the
MIRACLEAN® Griddle, operating temperatures should
be set 10°F to 25°F below conventional griddles.
2. Cook as usual, but after each batch scrape the
griddle in the work area, completely clean, using the
Keating replaceable blade scraper.
3. Locate the inverted “V’s” on the front of the griddle
cooking plate. Depending on your model you may
have from one to five thermostats. The “V’s” indicate
where the thermostat sensing bulbs are located
below the plate. See Figure 3-3.
4. Load the product to the left and right of each inverted
“V” first, then fill the area above the thermostat
sensing bulb. See figure 3-3.
Figure 3-3
Sample configuration of proper food placement
If you cook over the sensing bulb only, you are drawing
heat from that section, thus activating the thermostat to
call for more heat even though the area around it is still
at the temperature setting. This will result in higher
surface temperatures which will affect your cooking
and possibly product appearance.
GRIDDLE SURFACE
With proper care, the MIRACLEAN® surface and its
unique cooking properties will last for many years.
However, nicks or dents in the griddle surface may
cause the griddle surface to lift from the depressed
area. If nicks are close together, the surface may raise
and be torn when a spatula or scraper is used. Care
should be taken, as the damage done is irreparable.
CAUTION: DO NOT HACK, CHOP, HIT OR
CUT ON THE MIRACLEAN® SURFACE. YOU WILL
DENT THE STEEL PLATE UNDER THE TRIVALENT
CHROME. IT IS EVEN POSSIBLE TO HACK TWO
NICKS CLOSE TOGETHER AND ACTUALLY TEAR
THE MIRACLEAN® SURFACE AS THE CHROMIUM
WILL NOT STRETCH. BELOW IS A SKETCH
SHOWING THE SIDE VIEW OF A GRIDDLE PLATE
AND HOW THE SURFACE CAN BE DAMAGED.
PROPER USE OF THE UTENSILS SUPPLIED WITH
YOUR MIRACLEAN® GRIDDLE WILL PREVENT
SURFACE DAMAGE.
