The Garland clamshell grill, manufactured exclusively for
McDonald's, provides a method for efficient two-sided
cooking, while accommodating a variety of products. The
unit will also serve as a flat grill, and meets all of McDonald's
standards for safety, efficiency, and cleanliness.
SAFETY
Always follow these safety precautions when operating the
clamshell grill.
THIS GRILL MUST be operated by persons who have been
given adequate training.
CAUTION: THIS EQUIPMENT MUST ONLY BE
OPERATED UNDER AN APPROVED HOOD SYSTEM.
DO NOT OPERATE THE GRILL UNLESS IT HAS
BEEN COMMISSIONED (START-UP) BY A FACTORY
AUTHORIZED SERVICE CENTER.
DO NOT operate the grill without reading this
operation manual.
DO NOT operate the clamshell grill unless it has
been properly installed and grounded.
DO NOT operate the clamshell grill unless all service
and access panels are in place and fastened properly.
The Garland clamshell grill is a semi-automatic cooking
appliance. The upper platen is lowered automatically,
following the manual; two-handed initiation of the cooking
cycle, and the upper platen is raised automatically upon
completion of the cooking cycle.
When two sided cooking, the area between the upper platen
and the griddle plate should be regarded as a “danger zone”.
During two sided cooking the operator must not be within
this danger zone. When used as a flat grill, then this area is
no longer a danger zone, the platens do not move.
For whatever reason, be it cleaning, maintenance, normal
operation, any exposed person must use extreme caution if
within this danger zone.
In two side cooking the upper platen remains in the lowered
position by nature of it’s own weight. It is not locked down.
It can be raised by lifting of the handle on the front of the
platen, which pivots the platen about its rear mounting
point.
The clamshell grill may during its operation emit airborne
noise equivalent to a continuous A weighted sound pressure
level of 73dB(A).

The clamshell grill must only be used for single and two
sided cooking of foodstuffs in a McDonald’s store and must
not be used for any other purpose.
on the floor.
NOTE: The anchor assembly remains fastened to the back
wall of the grill bay.
WARNING: To avoid serious personal injury:
DO NOT attempt to repair or replace any part of the
clamshell grill unless all main power supplies to the grill
have been disconnected.
USE EXTREME CAUTION in setting up, operating and
cleaning the clamshell grill to avoid coming in contact with
hot grill surfaces or hot grease. Suitable protective clothing
should be worn to prevent the risk of burns.
WARNING: This appliance must not be cleaned with a
water jet. DO NOT apply ice to a HOT grill surface.
NOTE: All warning labels and markings on the grill, which
call attention to further dangers and necessary precautions.
HAZARD COMMUNICATION STANDARD, (HCS) The procedures in this manual include the use of chemical
products. These chemical products will be printed in bold
face, followed by the abbreviation (HCS) in the text portion
of the procedure. See the Hazard Communication Standard,
(HCS) manual for the appropriate Material Safety Data
Sheet(s), (MSDS).
WARNING: After turning the master power switch to
the START position, the grill will go through an initialization
process. If the upper platens are in the lowered position they
will return to their raised upper position. This movement
takes approximately 8 seconds.
After service or cleaning is complete, return the grill to its
position in the bay and reattach the anchors by placing the
retainer on the caster post and turning the knob clockwise to
tighten.
NOTE: For safety reasons, the grill must be secured in the
grill bay in this manner before operation can resume.
SHIPPING DAMAGE CLAIM PROCEDURE
Please note that the Garland equipment was carefully
inspected and packed by skilled personnel before leaving
the factory. The transportation company assumes full
responsibility for safe delivery upon acceptance of the
equipment.
What to do if the equipment arrives damaged:
1. File a claim immediately regardless of the extent of
damage.
2. Be sure to note, "visible loss or damage," on the freight
bill or express receipt and have the person making the
delivery sign it.
3. Concealed loss or damage: if damage is unnoticed until
the equipment is unpacked, notify the freight company
immediately, (within 15 days), and file a concealed
damage claim.
MAINTENANCE - the platen support arms carriage block
bearing bushes, the platen adjuster nuts, the platen support
(shoulder) bolt and the cam follower should be checked
annually for wear. Should there be any noticeable play in the
bearing bushes and any visible wear on the platen adjuster
nuts, platen support bolts or cam follower, then they must
be replaced.
MAINTENANCE - the audible alarm that sounds on platen
lowering, platen raising and 5 seconds before the completion
of the cooking cycle is to advise the operator that the platen
is about to move. The function of this device may be tested
by pushing the left hand CANCEL button. If no sound is
heard, ensure that the alarm volume is not set to low in
SYSTEM SETUP. If there is still no sound then a service
engineer should be called out to rectify the fault.
SERVICE AND CLEANING - The grill is secured in the
grill bay by the installer using two anchors that lock onto
the front casters. If the grill is to be moved out of the bay
for cleaning or service, remove the anchor from each caster
by turning the knob counterclockwise to loosen the retainer.
When the retainer is free of the caster, lay the assembly aside
LIGHTING INSTRUCTIONS
1. Ensure that the flexible gas hose is connected to the grill
and the power cords are plugged into the receptacles.
2. Turn the main power switch ON and allow the controls to
go through the power-up self-check. Once the control(s)
panel displays the word “OFF”, the unit is ready to begin
the heating process.
3. By selecting any of the menu items (pressing the menu
button) the controls will automatically initiate the
heating cycle appropriate for the menu item selected.
The burner(s) should light and heat until the temperature
specified by the menu item has been obtained.

UNIT INSTALLATION
Installation shall be made with the gas connector that has
been specified by The McDonald’s Corporation and is
supplied loose with the grill. The quick disconnect fitting and
gas shut off valve must be installed in the direction indicated
on their outer body.
National Code Requirements
The type of gas for which the grill is equipped is stamped on
the data plate on the inside rear of the unit and on the lower
front panel. Connect a grill stamped for Natural Gas (High
(H) or Low (L) Calorific Value) only to Natural Gas; connect
those stamped for Propane Gas only to Propane Gas. When
installing gas grills, the installation must comply with the
latest edition of the National Gas Installation Requirements.
When installing any type of gas-fired commercial kitchen
equipment, the requirements of the National Fire Protection
Association must be followed implicitly.
Electrical Instructions
All electrically operated appliances must be electrically
earthed in accordance with local codes; or in the absence
of local codes, with the latest edition of National Wiring
Regulations. A wiring diagram is located on the rear panel of
the grill. See rating plate in rear of grill, or lower front panel
for proper voltages.

UNIT INSTALLATION
Gas Connections, and pipe sizing
The size of the gas line is very important. If the line is too
small, the gas pressure at the burner manifold will be low.
This will cause slow recovery and delayed ignition. The
incoming gas pressure line should be a minimum of 1-1/2”.
All grills require a 3/4” connection.
Before connecting new pipe the pipe must be blown out to
dispose of any foreign particles. These particles will cause
improper operation.
When using thread compound, use small amounts on male
threads only. Use a compound that is not effected by the
chemical action of LP gases. Avoid applying compound to
the first two threads to prevent clogging of the burner orifices
and control valve.
Have the installer check all gas plumbing with a soap
solution for leaks. DO NOT USE matches, candles or other
ignition sources in checking for leaks.
The grill must be disconnected from the gas supply system
when pressure testing of that system at pressures in excess
of 150mbar.
Test all piping and connections for gas leaks. A rich soap
solution should be used for this purpose. Never use a
flame.
Ventilation and Clearance
One of the most important considerations of efficient grill
operation is proper ventilation and air supply. Insure the
grill is installed so the products of combustion are removed
efficiently and the ventilation system does not produce drafts
that interfere with proper burner operation.
Proper operation of exhaust fans (proper speed, rotation and
adjustment) is essential. In addition to the exhaust system the
make-up air system (HVAC) for the kitchen is the air supply
for the combustion air for the burners. Proper incoming air
is essential for all gas operated equipment. Poor incoming
make-up will cause inefficient burner operation, delayed
ignition and possible burner failure. Insure air balancing is
performed on the system as required by the PMS card.
Any ventilation system will break down if improperly
maintained. The duct system, the hood, and the filters must
be cleaned on a regular basis and kept grease free.
Check the data plate to determine the proper type of gas
before connecting the quick disconnect or piping from the
building gas supply.
An incoming gas pressure test nipple is provided on the
incoming gas manifold for pressure checks.
Minimum incoming gas pressure for Natural Gas is 15 mbar.
Maximum incoming gas pressure for Natural Gas is 34.5
mbar.
Minimum incoming gas pressure for LP Gas is 27.5 mbar.
Maximum incoming gas pressure for LP Gas is 34.5 mbar
Burner operating gas pressure can be checked at the outlet
side of the gas valve at the pressure test point.
Burner manifold pressure for Natural Gas must be 8.75 mbar.
Burner pressure for LP Gas must be 25 mbar.
To adjust the burner pressure, remove the sealing screw
from the pressure test nipple, connect a manometer, remove
the sealing cap on the gas valve regulator, turn on the grill,
adjust the screw in the regulator to give the correct pressure,
turn off the grill, refit the regulator sealing cap, remove the
manometer, replace the seal screw in the test nipple and test
for gas leaks.
Gas pressures should be checked by the local Gas Company
or an authorized service agency only.
The room containing the grill is required to have a permanent
air vent. The minimum effective area of the vent shall be 4.5
cm² per kW. Air vents shall be of such a size to compensate
for the effects of any extract fan in the premises.
Changing to a different type of gas
Changing from one gas category to another must only be
done by a Qualified Gas Engineer.
To change from category II to III or vice versa, the gas valve,
enrichment tube igniter and orifice must be changed to that
supplied by the Authorized Service Agency for the gas you
are changing to. On completion of changing these three
components, you should test all joints for leaks, verify that
the manifold pressure is adjusted to the value given in the
specification pages in this manual, and repeat the burner air
adjustment procedure. This is to be found on the following
page in this manual. When the burner is correctly adjusted,
the alternate rating plate decal must be placed over the
existing rating plates to reflect the new category for which
the grill is set.
To change from one gas type to another within the same
category (High to Low Calorific Value Natural Gas or vice
versa), change the orifice to that supplied by the Authorized
Service Agency.

INITIAL SETUP OF GRILL
Burner Air Adjustment
1. Visually inspect the color of the burner tile. After the
burner has been running for several minutes, the tile
surface should be glowing DULL ORANGE, with very
little or no blue haze visible above the tile surface. (Note:
Just after the burner ignites, it will have some blue haze
above the tile surface. This will remain until the tile has
heated up and is glowing dull orange). If the burner does
not become dull orange, then the burner air supply needs
to be adjusted.
2. Loosen the lock nut holding the air adjustment in place.
Slowly turn the air adjustment out (counterclockwise).
The burner tile surface should begin to brighten.
3. If it brightens, then continue turning the screw
counterclockwise until the burn tile surface brightens
and then begins to have a blue haze to it again. Stop
turning the adjuster. Begin turning the adjuster in while
COUNTING THE NUMBER OF TURNS until the tile
again has a blue haze. Stop tuning. Divide the number
of turns turned in by half and unscrew (counterclockwise)
the adjuster that number of turns. The adjustment is now
complete. Tighten down the lock nut.
Ignitor Adjustment
The Igniter location is factory set and does not normally
require adjustment. Adjustment should only be conducted if
the Micro-Amp (μA) reading taken by placing a Micro-Amp
(μA) meter in line between the ignition module and the flame
sense wire reads below 0.22 Microamps (μA). The normal
reading is around 0.80 (μA) to 1.5 (μA). If the reading is
low, the igniter can be a moved up or down to achieve the

DESCRIPTION OF GRILL CONTROLS
General Overview
The grill control will allow for 2 functions, both described in
the following sections.
The “Normal Operating Mode”, also known as the Cook
Mode is the mode in which is used during normal cooking.
In the normal operating mode, the operator can start a cook
cycle, cancel a cook cycle, view actual temperatures, view
settings for the currently selected menu item, scroll to
another menu item (Both forward and backward), and enter
the “Programming Mode”.
The “Programming Mode” is the mode in which the grill
operator, manager, or service technician can change various
programmed features to specific menu items, or change
features that would apply to the entire grill.

Controls power to the grill and must be turned “ON” to start
the operation. The controller displays will be active
when the switch is “ON”.
Indicator Lights
There are four, (4), indicator lights, indicating the temperature
status of each zone on the grill, one, (1), on the upper platen,
(top light), and three, (3), on the lower, (lower section of
lights, top to bottom; rear, center, front, respectively - see
diagram on previous page). Each light can display three,
(3), different colors, indicating temperature status for the
corresponding zone.
Red: The zone(s) is too hot (more than 79ºF/43ºC over
the set temperature) or heat zone(s) failure.
Amber: The zone(s) is calling for heat.
Ignition Status Indicator Light - Center LED
The center light in the lower section indicates burner ignition
status in the following ways:
Green: status OK.
Amber: Flashing indicates that ignition retrial has
occurred at least once, (4 tries maximum). Once activated
the flashing amber light will continue to flash, until ignition
is achieved, (in four tries or less, total), at which time the
light will remain amber, but stop flashing.
Red: Indicates that ignition was not accomplished after
4 tries, and that the ignition system has been shut down,
requiring a manual reset, (power-down).

Multi-Stage Cooking
If you have version 7.30 EPROM chip software, your
controller is equipped with the new Multi-stage cooking
feature.
With Multi-Stage cooking, the product being cooked is
cooked using multiple gap settings for a selected period of
time.
For example, during 4:1 cooking, the platen would normally
gap at a gap setting of .416 (Four-hundred and sixteen
thousands) for the entire length of the cook cycle.
With multi stage cooking, the platen may gap at the
beginning of the cook cycle for .416 for only 20 seconds. At
the interval of 21 seconds, the gap may change to .400 for
another 25 seconds.
At the 46 second interval (in the remove time), the platen
may regap at .420.
NOTE: the above mentioned example is IS NOT the
McDonalds multi gap formula for 4:1 cooking.
All of the “CLAM” menu items programmed in this 7.30
eprom chip have options to cook using the multi-stage gap
feature.
Currently, 10:1 - CLAM, and 4:1 - CLAM are the only menu
items with a factory default program with multiple gaps.

An open probe condition has occurred. The controller will
turn the heater controlled by the malfunctioning probe OFF.
If the open probe condition should correct itself; the control
will return to the ''IDLE MODE ''.
“Clam did not go down”
Occurs if the platen does not reach the proper position (GAP
SETTING) in 30 seconds. You may cancel the message by
pressing the “TEMP” button.
“Upper Platen Stuck”
Occurs when the controller does not get an upper platen
setting signal 15 seconds after it starts to raise
the platen. In order to return to the “IDLE MODE”, the
controller must get a upper platen setting signal. You
may cancel the message by pressing the “TEMP” button
followed by the GREEN (“RAISE”) button in order to retry
raising the platen.
“Eprom Corrupt”
Displayed at startup when the controller detects a corrupt
menu item or when a new version of the
software is loaded. To cancel this message, switch the grill
“off” and “on” again at the main power switch.
“Ignition Failure”
“High Limit”
Occurs when:
1. The Controller senses a zone at 465( F (241( C)
NOTE: The Controller has 2 High Limit tests located at the
end of the menu item list. If the test is enabled, that test will
heat the zone (Platen, or Grill) to 465(, and the controller will
flash “High Limit”
“Motor Overcurrent”
Occurs when:
1. The upper platen has been mechanically resisted the
platen will stop.
2. The platen control motor is inoperative. Turn the
“MASTER POWER” switch OFF, then ON again.
“Faulty Element / Shorted Probe”
Occurs when the controller does not detect a proper
temperature response. Also, the RED LED will light,
indicating which element /probe is in error.
NOTE: Should all four, (4), LED’s flash RED approximately
six, (6), minutes after the unit is turned on, ensure that the
main three-phase, (large), power cord is plugged in and the
