2

This appliance and its pressure regulator must be isolated from the gas supply piping system by closing
its individual manual shuto valve during any pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 PSIG (3.45KPA). For the protection of you and your property, we
recommend a qualified installing agency install this unit. They should be familiar with gas installations
and your local gas company requirements. In any case, your gas company should be called to approve
the final installation. Detailed instructions should be posted in a prominent location, to be followed
in the event the operator smells gas. Obtain the instructions from the local gas supplier.

GAS PIPING

Gas piping will need to be installed correctly and be an appropriate size to provide a supply of gas
sucient to meet the full gas input of the appliance. If the appliance is to be connected to existing
piping, it will need to be checked to determine if it has adequate capacity before installation. Joint
compound should be used sparingly and only on the male threads of the pipe joints. Any compounds
used will need to be resistant to LP and Natural gases.

Any loose dirt or metal particles which are allowed to enter the gas lines on this appliance will damage
the valve and aect its operation. When installing this appliance, all pipe and fittings must be free from
loose dirt.

MANUAL SHUT-OFF VALVE

A manual shut-o valve should be installed upstream from the union and within six [6] feet (1.829 m)
of this unit.

GAS PRESSURE REGULATOR

A convertible pressure regulator is provided with each griddle. It should be connected to the inlet
pipe at the rear of the unit. The gas supply line is then connected to it. It is shipped set for 5-inch
water column manifold pressure for use with natural gas. For LP use, the pressure will need to be
adjusted as directed in the steps below.

GAS CONVERSION

This griddle is equipped with fixed orifice hoods and is shipped from the factory for use on natural
gas or LP. To convert to LP [propane] from natural gas [or vice versa], install the alternate burner
orifice hoods located in the grease drawer, using the following procedure.

i. Remove the front panel by removing the screws located on the front and bottom.
ii. Remove the burners from the orifice hoods. This is accomplished by removing the burner mounting
screws and sliding the burners o the hoods.

iii. Remove the natural gas orifice hoods and install the propane hoods the were provided.
iv. Reinstall the burners.

v. Reinstall the front panel.

vi. Remove the slotted, or hex-headed, plug from the pressure regulator. Invert the plug and reinstall.

The letters “LP” should now be visible on the plug. The regulator is now set for 10-inch water column
manifold pressure. To check pressure, a 1/8-inch pipe plug on the manifold can be removed for
attaching a pressure gauge.

2M-Z22112 Rev - Owner’s Manual for Lang 4xx-Series Gas Griddles

CONNECTING GAS SUPPLY LINE

The gas inlet of the griddle is sealed at the factory to prevent the entry of dirt and debris. Do not
remove this seal until the actual connection is made to the gas supply line.

CHECKING FOR GAS LEAKS

Soap and water solution or other material acceptable for the purpose should be used in locating
gas leakage. Matches, candle flame, or other sources of ignition should not under any circumstances
be used for this purpose. Check the entire piping system for leaks immediately after connection.

LIGHTING INSTRUCTIONS

The griddles are equipped with standing pilots and should be lit immediately after the gas is turned
on. Pilot flames can be lit and observed through the front panel view ports, but the best access for
lighting the pilot is from the bottom of the unit, behind the center wall. When griddle is first lit, it will
smoke until the preservation oils and impurities are burned o. Use the following procedure to light
all pilots.

i. Turn o the main valve to the unit and wait 5 minutes to clear gas.

ii. Turn o all knobs and pilot valves.
iii. Turn on the main valve and light all pilots.
iv. Turn the burner knobs to desired setting.

v. To turn burners o, turn knobs o.

PILOT LIGHT REGULATION

Adjust pilot light flames as small as possible, while still being high enough to light burner immediately
when the burner valve is turned on high. The flame should be solid blue with no flickering or yellow
tipping.

BURNER ADJUSTMENT

i. Remove the front panel.

ii. Set the thermostat or control setting of one burner to 450° F (232° C).
iii. Loosen the shutter retaining screw, and close the air shutter on the front of the burner to give a soft
blue flame with luminous yellow tips and open to a point where the yellow tips disappear and a hard
blue flame with darker blue inner cone is obtained. Tighten the shutter screw.
iv. Repeat for all burners.

v. Return thermostat to o position and return power switch[es] to “OFF” and proceed to replace the

front panel.

DAILY OPERATION

GRIDDLE CARE

It takes very little time and eort to keep the griddle
attractive and performing at top eciency. If grease
is permitted to accumulate, it forms a viscous residue
and then carbonizes, making it extremely dicult to
remove. To prevent this condition, the following
suggestions for cleanliness should be followed.

i. STANDARD STEEL SURFACE
After each use, scrape the griddle with a scraper
or flexible spatula to remove excess grease and food
and maneuver it into the grease chute. If there is an
accumulation of burned on grease and/or food, the
griddle should be thoroughly scoured and reseasoned.
Use pumice or griddle stone while the griddle is warm.
Do not use steel wool because of the danger of steel
slivers getting into the food.

CHROME SURFACE
After each use, scrape the griddle with a razor-sharp
scraper. Following that, use a soft, damp cloth and
a non-silicate, non-abrasive, non-chlorinated cleaner
to wipe the surface clean. Follow this by wiping with
a clean damp cloth with no cleaner. On chrome
surfaces, never use pumice, griddle stones, abrasives,
commercial liquid grill cleaner, and never strike the
griddle surface with a sharp and/or hard instrument.

ii. Daily use a clean cloth and a good non-abrasive
cleaner to clean the stainless steel body of the
griddle is recommended. Wipe the polished front
with a soft cloth so not to scratch the finish.

iii. At least once a day, remove the grease drawer and
wash it using the same process as an ordinary cooking
utensil. The drawer is removed by pulling forward until
it is released from its track. The grease pan on the
front is hot and contains hot grease. Take care when
removing and emptying the tray. The tray should
be checked and emptied on a regular basis.

SEASONING THE GRIDDLE HEATING SURFACE

After the griddle has been thoroughly cleaned, it should
be seasoned to prevent food from sticking. Before using
and after each thorough scouring, season the griddle
heating surface in the following manner.

i. Turn the temperature control dials to 350°F (177°C).

ii. Using a clean cloth, not a spatula, spread a thin film

of cooking oil over the griddle cooking surface. This
film should remain on the hot griddle surface for half
an hour.

iii. Remove the excess oil and wipe clean.

iv. Apply another film of cooking oil over the hot cooking

area for another half hour and again remove excess
oil and wipe clean. The griddle surface should now
be ready for use.

TEMPERATURE CONTROL

SNAP-ACTION THERMOSTAT

The temperature controls are combination “ON/OFF”
switches and thermostats. Turning the dial knob
automatically maintains the selected heat range.
There is one thermostat for every twelve [12] inch
(305 mm) wide section that operate independently.

SELECTRONIC SOLID STATE

To ignite burners, flip the switch corresponding to
each section you wish to use to the “ON” position.
Next, Turn the adjustment knob to the desired
temperature [this system adjusts in increments

of 25° F (14 ° C)].

COOKING

Set the thermostat dial knob at the desired temperature.
After a short pre-heating period, the thermostat will
automatically maintain the selected temperature.

IDLING

During idle periods, to save on operating costs, lower
the temperature setting of the thermostat to about
250°F (121°C). It is not necessary to maintain cooking
temperature during idle periods, as the griddle can
quickly be reheated to the desired temperature.
