QUALIFIED TO WORK WITH ELECTRICITY AND PLUMBING.
IMPROPER INSTALLATION CAN CAUSE INJURY TO PERSONNEL
AND/OR DAMAGE TO EQUIPMENT. UNIT MUST BE INSTALLED IN
ACCORDANCE WITH ALL APPLICABLE CODES.
NOTICE: The data plate is located on the inside of the hood wrap. The
Clamshell® voltage, wattage, serial number, clearance and gas
specifications are on the data plate. This information should be
carefully read and understood before proceeding with the installation.
NOTICE: This unit is approved to be installed only on equipment which meets
NSF standards, and for which the adapter kit is provided.
WARNING: WHEN MULTIPLE CLAMSHELLS® ARE USED ON A GRIDDLE, ALL THE
CLAMSHELLS MUST BE CONNECTED TO THE SAME 120V SOURCE.
4.1 Electrical Connection
The Clamshell® is supplied with a cord and plug. The receptacle is not provided with the Clamshell®.
Follow the receptacle manufacturer’s instructions when connecting the receptacle to the power supply.
When multiple Clamshells are installed on the same griddle, you must plug them into the same
electrical circuit (receptacle) to prevent from doing damage to the units transformers.
4.2 Gas Connection
WARNING: BEFORE LIGHTING, USE A SOAP AND WATER SOLUTION TO TEST
ALL JOINTS FOR GAS LEAKS.
This Clamshell® is manufactured for use with the type of gas indicated on the nameplate.
Contact the factory if your type of gas does not match the nameplate data.
All gas connectors must be in accordance with local codes and comply with the National Fuel
Federal Gas Codes ANSI Z223.1 latest edition.
There are two gas connections involved in the installation of the Clamshell®:
The first is the gas supply to the Clamshell® itself. This connection should be made positioning
the manual shut-off valve supplied with the Clamshell® to isolate the appliance from the kitchens
main gas supply during any future service activity (See figure 1). (A service agent should be able
to shutoff and disconnect the gas supply to the Clamshell® without affecting the main gas supply
to the kitchen.) Use gas lines that have a minimum diameter of at least 1/2 an inch.
The second is the gas supply to the base appliance (the appliance to which the Clamshell® is
mounted). The Clamshell® has an external solenoid valve (the Automatic Cutoff Valve (ACV))
at the end of a flexible conduit. The ACV must be installed in line with the gas supply to the base
appliance in a location, which will ensure the ACV is not exposed to temperatures above 175°F
(See figure 1). Remove the cover to the ACV to ensure the correct flow direction through the
valve when making the connections. Replace the cover after the connections are complete. Use
gas lines that have a minimum diameter of at least 1/2 an inch.
NOTE: If this Clamshell® is received already mounted on a Lang griddle no further installation is
required. If this Clamshell® is a separate unit proceed to section 4.3 below.
NOTICE: The installation of any components such as a vent hood, grease
extractors, fire extinguisher systems, must conform to their applicable
National, State and locally recognized installation standards.

5. INITIAL START UP
5.1 Initial Lighting Procedure for an Clamshell®
WARNING: DURING INITIAL USE, OR USE AFTER SERVICE, IF THE PILOT DOES
NOT IGNITE ON FIRST TRY THE MAIN GAS VALVE MUST BE TURNED
OFF FOR AT LEAST FIVE MINUTES.
NOTICE: While cooking, the Clamshell® must be monitored at all times.
DO NOT leave the Clamshell® unattended while cooking.
NOTICE: Fan in Clamshell® runs continuously. For the safety of the unit, the fan
must run continuously to provide cooling to the electrical components.
Component cooling is required if the base unit is running. If power to
the Clamshell® is turned off, gas to base will be turned off. If it is
necessary to remove power from the Clamshell®, the base unit must be
cooled below 200°F first.
•The Clamshell® has two positions, the lowered position for cooking and the raised position for griddle
loading, cleaning, or griddle only use.
•No thermostats are provided for temperature control. The Clamshell® is a radiant cooking device,
which operates only in the lowered position.
•Ignition is automatic and occurs as the Clamshell® is lowered.
•Raising the Clamshell® turns the gas burner off.
5.2 Initial Lighting Procedure for the Griddle/Charbroiler
See Operator manual for the griddle/charbroiler.

6. OPERATION
6.1 Clamshell® Operation
CAUTION: ALWAYS KEEP THE AREA NEAR THE APPLIANCE FREE FROM
COMBUSTIBLE MATERIALS.
CAUTION: KEEP FLOOR IN FRONT OF EQUIPMENT CLEAN AND DRY. IF SPILLS
OCCUR, CLEAN IMMEDIATELY, TO AVOID THE DANGER OF SLIPS OR
FALLS.
NOTICE: While cooking, the Clamshell® must be monitored at all times. Do not
leave the Clamshell® unattended while cooking.
•The Clamshell® has two positions, the lowered position for cooking and the raised position for
griddle loading, cleaning, or griddle only use.
•No thermostats are provided for temperature control. The Clamshell® is a radiant cooking device,
which operates only in the lowered position.
•Ignition is automatic and occurs as the Clamshell® is lowered.
•Raising the Clamshell® turns the gas burner off.
•Place food on griddle/charbroiler and immediately lower the Clamshell®. The tiles will glow
reddish-orange in approximately 30-45 seconds. The radiant heat from the Clamshell® will cook
from the top while the griddle/charbroiler cooks the product from the bottom.
•Load product under the Clamshell® following the normal loading procedures for the
griddle/charbroiler to which it is attached.
6.2 Operation When Attached to a Griddle/Charbroiler
See Operator’s Manual for the base unit.

12
7. SEQUENCE OF OPERATION
7.1 Power On
•When the Clamshell® is plugged in, 115 Volts is applied to the blower motor. The Clamshell® is
designed to have a constantly running blower motor.
•The air switch then senses the blower motor, closes, and applies the 115 Volts to a 24 VAC transformer.
•The transformer then supplies 24 VAC to the tilt switch, and to the automatic cutoff valve.
•The 24 VAC to the automatic cutoff valve opens the gas valve to the griddle/charbroiler, thus allowing the
base unit to operate.
•When the Clamshell® is lowered, the tilt switch allows 24 VAC to go to the spark module.
•The spark module then supplies 24 VAC to open the Clamshell® gas valve, and high voltage to the spark
igniter.
•When the burner ignites, the sense probe senses the flame is ignited and the spark module turns off the high
voltage to the spark igniter.
•When the Clamshell® is raised the tilt switch opens the 24 VAC to the spark module, which removes the
24 VAC to the gas valve, turning off the Clamshell®.
