 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.

♦ XL Hood

 The Hood dimension (including griddle) are 22¼” (55.88cm) High with hood down, 44¾”

(113.67cm) High with hood up, 31½” (80cm) Deep, and 24” (61cm) Wide.

 The Hood wrap is constructed of stainless steel and uses infrared heat to broil the product.

♦ Pane Bella

 The Pane Bella dimensions are 12” (30.5cm) High with hood down, 24.5” (62.25cm) with hood up,

16” (40.5 cm) Deep and width is dependent on model number.

INSTALLATION

RECEIVING THE GRIDDLE

Upon receipt, check for freight damage, both visible and concealed. Visible damage should be noted on the freight

bill at the time of delivery and signed by the carrier's agent. Concealed loss or damage means loss or damage, which

does not become apparent until the merchandise has been unpacked.

If concealed loss or damage is discovered upon unpacking, make a written request for inspection by the carrier's

agent within 15 days of delivery. All packing material should be kept for inspection.

Do not return damaged merchandise to Lang Manufacturing Company. File your claim with the carrier.

Prior to un-crating, move the range as near its intended location as practical. The crating will help protect the unit

from the physical damage normally associated with moving it through hallways and doorways.

ELECTRICAL CONNECTION

LG / LGS

There is one power supply connection on 2, 3 and 4 foot griddles. There are two power supply connections on 5 and

6-foot griddles. Refer to the power supply chart in the Technical Data portion of this manual, for proper power

supply size.

There is (1) one 1 1/4-inch conduit knockout on 2, 3, and 4-foot griddles located at the rear of the griddle, through

the back and the bottom of the griddle body. There are (2) two 1 1/4-inch conduit knockouts provided on the 5 and 6

foot griddles. Use a supply wire suitable for at least 90 degree centigrade.

The model LG-S griddle is shipped from the factory wired for 208/240 or 480 volts, the 208/240 griddle is a dual

voltage design. 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 as indicated on the tag to the terminal strip. The 480 volt griddle can be operated on 480 volts only.

All PB-24 grills are supplied with a 48” 10 gauge cord and a NEMA L6-30P plug.

The PB-12 grill is supplied with a 48” 12 gauge cord and a NEMA L6-30P plug on the 240 Volt and NEMA 5-15P

plug on the 120 Volt

XL HOOD

Power connection can be made at a two pole terminal block located next to the power connection on the grill.

All XL Hoods are single phase and come in either 208 Volt or 240 Volt.

INSTALLATION CONT’D

PHASING

LG / LGS

All griddles are shipped from the factory set up for a three- phase service. Rearrange the wires in the power supply

terminal block to convert the griddle to single phase. Rephasing the griddle is not chargeable to Lang Manufacturing

Company as warranty. To convert to single phase follow the chart below.

Note: The times and temperatures in this chart are intended as a general guide and starting

point. Your actual times and temperatures may vary from this chart.

If different temperature settings are to be used, select one side of the griddle and

operate at the lowest temperature. Adjoining sections should be set at

progressively higher temperatures. Do not try to operate the end sections hot and

the center sections cool.

GENERAL CONT’D

OPERATIONS

An understanding of how the griddle sections are controlled will be a valuable aid in

loading your griddle.

Each 12 inch section of your griddle is independently controlled by a temperature

controller. The temperature control sensor is mounted in the center of each cooking

section under the griddle plate.

If the product is loaded directly over the temperature sensor, that section will turn on and

the burner will heat the entire cooking section. If the product is loaded to the side, front

or back of the temperature sensor, the thermostat will react to the temperature change

much slower.

During slow periods with minimal loads, do not load directly over the thermostat sensors

as this will unnecessarily turn the burners on and overheat the remainder of the section

not being utilized.

Turn the product and continue cooking until it has reached its desired degree of doneness.

Remove the product from the griddle.

When reloading the griddle, first use the griddle surface on which a previous load was not

placed. This will help insure the proper griddle temperature.
