Exterior Construction
Griddle
The griddle dimensions are 17” (43.18cm) High, 30” (76.20cm) Deep, and width is dependent on the
actual model number.
The Sides, Bottom, and Rear wall are constructed of double wall stainless steel, which allows closer
installation to combustible surfaces.
The griddle surface is made of 1” thick, highly polished steel to reduce hot and cold spots, recovery
problems, warping, and ensure even heat to the edges of the griddle.
TH Hood
Clamshell® Hood dimensions (including griddle and legs) are 22¼” (55.88cm) high with hood lowered,
(44¾” [113.67cm] high with hood raised, 31½” (80cm) deep, x 24” (61cm) wide.
The hood wrap is constructed of stainless steel.
There is a 3” clearance between griddle and hood.
Controls
Griddle
Each twelve-inch section has a manual thermostat with a temperature range of 175°F to 450°F in 50°
increments.
The thermostat is mounted in a fully enclosed, air-cooled compartment for protection from heat and
grease.
Each thermostat has a pilot light indicating when heating elements are energized. Light shuts off when
griddle reaches set temperature.
TH Hood
The TH Hood has an “on/off” toggle switch located in the griddle base control area that energizes the
heater. A tilt switch is integrated in the top of the hood that activates the heater to “full on” when lowered,
standby when raised.
An “on/off” heat indicator lamp is located next to the “on/off” toggle switch.

EQUIPMENT DESCRIPTION continued
Technical
Griddle
The griddle is standard 208/240 dual voltage, 3 phase, for on-site installation to either 208V or 240V.

INSTALLATION
IL1562
Std Leg
Above: typical leg installation.
Leg Installation
The TH Hood comes standard with 4-inch stainless steel legs. An optional stand is available.
To install the legs, remove the legs from the grease drawer. Using extreme caution elevate the griddle
10 inches off the ground and install the legs in the threaded holes provided.
To install the stand, turn the stand so that the legs are sticking straight up positioning the side with the
three holes to the rear. Place the metal spacer on the legs and slide the shelf over the legs until it
rests up against the spacer. Tighten the Allen screws on the shelf so that it is stationary. If casters were
ordered, install the caster onto the threaded stud provided in the bottom of the leg to the desired height
and tighten the Allen screws on the stand. Flip stand over onto the legs so that the three holes are in the
back. Using extreme caution set the griddle onto the stand. Using the threaded holes provided on the
bottom of the griddle screw the 5/8 bolt through the stand into griddle.

INSTALLATION cont.
Ventilation and Clearances
Standard minimum clearance from combustible construction is as follows.
2” from side
2” from back
These griddles may be set directly, without legs, on a curbed base or non-combustible surface.
If the griddle is set without legs on a non-combustible oor or a curbed base, maintain a 4-inch
back clearance.
Do not install the griddle directly against a non-combustible back wall or surface.
Do not install the griddle closer than 12 inches from an uncontrolled heat source (char broiler etc.).
Keep the appliance area free and clear of combustible material and do not obstruct the ow of
combustion or ventilation air.
Electrical Connection
Griddle
The electrical connection must be made in accordance with local codes or in the absence of local
codes with NFPA No. 70 latest edition (in Canada use: CSA STD. C22.1).
A 1 1/4-inch conduit knockout through the back and the bottom of the griddle body is located at the
rear of the griddle. A 3-pole terminal block is provided for service connections and can be accessed
through a removable panel on the back of the griddle. Use a supply wire suitable for at least 90
degree centigrade.
The griddle is shipped from the factory wired 208/240 dual voltage. Jumper wires on terminal strip
next to the main power supply connection determine the griddle voltage. For a 208 - volt power
supply, leave the jumpers in place. For a 240 - volt power supply disconnect the jumpers to the
terminal strip as indicated on the tag.
TH Hood
For power connection to the hood, a two pole terminal block is provided next to the three pole
terminal block on the back of the griddle.
The hood is shipped either 208 or 240 volt single phase only.
The voltage must be specied when ordering.
WARNING: MAKE SURE THE MAIN POWER SUPPLY TO THE GRIDDLE IS
TURNED OFF AT THE SOURCE PRIOR TO CONNECTING POWER
TO THE GRIDDLE.
CAUTION: BE SURE THE POWER SUPPLY VOLTAGE MATCHES THE
VOLTAGE SPECIFIED ON THE NAMEPLATE LOCATED ON THE
FRONT OF THE GRIDDLE.
