NOTICE
Local codes regarding installation vary greatly from one area to another. The National Fire Protection Association,
Inc., states in its NFPA 96 latest edition that local codes are the “authority having jurisdiction” when it comes to
installation requirements for equipment. Therefore, installations should comply with all local codes.
Lang reserves the right to change specifications and product design without notice. Such revisions do not entitle
the buyer to corresponding changes, additions, or replacements for previously purchased equipment.
Lang appliances are intended for commercial use only, not for household use.
The installation must conform with local codes, or in the absence of local codes, with the National Fuel Gas Code,
ANSI Z223.1, Natural Gas Installation Code, CAN/CGA-B149.1, or the Propane Installation Code CAN/CGA-
B149.2, as applicable, including:
1. The appliance and its individual shutoff valve must be disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in excess of 1/2 psi (3.45 kPa).
2. The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve
during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psi (3.45
kPa).
CLEARANCES
WARNING
MINIMUM CLEARANCES FROM COMBUSTIBLE CONSTRUCTION
There must be adequate clearance between the sectional range and combustible construction. Clearance must
also be provided for servicing and for operation.

Floor* 0" 0" 0" 0" 0"
Do NOT install sectional charbroilers next to combustible materials.
* Models with 6" legs or casters are suitable for installation on combustible floors.
Adequate clearance must be provided in the aisle in front of the unit to permit operation (including opening of
doors and/or removal of grease drawers, drippings trays, and/or oven racks), as well as for servicing. No ad ditional
clearance is required for servicing as the sectional range is serviceable from the front.
Models with a convection-type oven require a minimum clearance of 2" between the motor on the back and noncombustible construction. Care must be taken to provide adequate air circulation to prevent the motor from
overheating.

Minimum clearance from noncombustible construction is zero on the sides and back for all models (except for
models with a convection-type oven).
The high-temperature flue products flow out through the top of the flue riser of all models, and from the top of
open-top and charbroiler models. Installation under a vented hood is recommended.
Salamander broilers and cheese melters mounted on the flue riser of a sectional range may require additional
minimum clearances (see the documentation for those appliances).

CHEF SERIES SECTIONAL RANGE SPECIFICATIONS
VENTILATION
WARNING
Improper ventilation can result in personal injury or death. Ventilation which fails to properly remove flue products
can cause headaches, drowsiness, nausea, or could result in death.
All gas appliances must be installed in such a manner that the flow of combustion and ventilation air is not
obstructed. Provisions for adequate air supply must be provided. Do not obstruct the area under the control panel
or below the oven door (on the front), or the area below the flue riser (on the back) as combustion air enters
through these areas.
NOTICE
Proper ventilation is the owner’s responsibility. Any problem due to improper ventilation will not be covered by the
warranty.
Be sure to inspect and clean the ventilation system according to the ventilation equipment manufacturer’s
instructions.
Air for combustion enters from the front below the valve panel, as well as from the rear into the burner box. Ranges
with solid tops (griddles and hot-tops) vent their flue products up the flue riser. On units with a base oven, combustion
air enters from the front below the oven door. Oven flue products are vented up the flue riser.
Lack of sufficient ventilation will cause poor burner and pilot operating characteristics, resulting in inefficient
performance. Such conditions also cause high ambient temperatures at the manifold area and create valve and
thermostat problems.
If a ventilation canopy is used, it is recommended that the canopy extend 6" past the sectional range and that the
bottom edge be located 6'6" from the floor. Filters should be installed at an angle of 45° or more from the horizontal.
This position prevents dripping grease, and facilitates collecting the run-off grease in a drip pan under the filter.
A strong exhaust fan tends to create a vacuum in the room and may interfere with burner performance or may
extinguish pilot flames. Fresh air openings approximately equal to the fan area will relieve such a vacuum. The
exhaust fan should be installed at least 2" above the top of the flue riser.
If the sectional range is connected directly to an outside flue, a CSA design certified down draft diverter must be
installed.
In case of unsatisfactory performance by any gas appliance, check the appliance with the exhaust fan turned OFF. Do
this only long enough to check whether doing so corrects any problems with equipment performance. Then turn the
exhaust fan back on and let it run to remove any exhaust that may have accumulated during the test.
GAS SUPPLY
The sectional range is design-certified for operation on natural or propa ne gases. The sectional range is shipped
configured and adjusted for the type of gas specified by the purchaser, which is indicated on the serial plate (see
Figure 1 on page 3). Connect the sectional range ONLY to the type of gas for which it is configured and adjusted.
Each section has a 1-1/4" front gas manifold that can be coupled to adjacent section(s). Sections can be ordered with
an optional 1" rear gas connection with a male NPT connector. Minimum supply pressure is 7" W.C. for natural gas,
11" W.C. for propane. An external pressure regulator and shut off valve must be provided. If using a flexible-hose gas
connection, the I.D. of the hose must not be smaller than the connector on the unit and must comply with ANSI
Z21.69. Provide an adequate means of restraint to prevent undue strain on the gas connection.
If applicable, the vent line from the gas appliance pressure regulator shall be installed to the outdoors in accordance
with local codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1, Natural Gas Installation Code, CAN/CGA-B149.1, or the Propane Installation Code CAN/CGA-B149.2, as applicable.
An adequate gas supply is imperative. Undersized or low pressure lines will restrict the volume of gas required for
satisfactory performance. A 1/8" pressure tap is located on the manifold to measure the manifold pressure. The
supply line to the sectional range should be no smaller than the inside diameter of the pipe on the se ctional range to
which it is connected.

CHEF SERIES SECTIONAL RANGEOPERATION
OPERATION
DANGER
EXPLOSION HAZARD
In the event a gas odor is detected, shut down equipment at the main shut off valve. Immediately call the
emergency phone number of your gas supplier.
CAUTION
If a pilot flame pilot should go out, the flow of gas to the corresponding burner is NOT interrupted. Consequently, it
is the responsibility of the operator to check the ignition of each burner immediately EVERY TIME a burner is
turned on. Should ignition fail after 10 seconds, turn off the burner, wait 5 minutes, and then try again.
LIGHTING AFTER GAS HAS BEEN SHUT OFF
When turning on the main gas supply to a sectional range, do the following:
1. Make sure that all the control knobs and power switches of all the connected appliances are in the OFF position.
2. Turn on the gas-supply shut-off valve(s).
3. Light the standing pilots of each connected appliance.
4. Light the ovens of the sectional range first, then wait six minutes before turning on the top sections. This enables
all air to be purged from the sectional-range gas piping.
SHUTDOWN OF ENTIRE RANGE
To place the range in a standby state (ready for use), Oven bases with the electronic ignition option, turn all burner
control knobs to OFF, set all thermostats to their lowest position, and switch all ovens OFF. The pilots will remain lit.
On the standing pilot units, same as above except turn thermostat knob to the “OFF” position. The pilots will remain
lit.
To completely shut down the range for an extended period (or prior to disconnecting the gas supply), place the range
in a standby state (as described in the previous paragraph), then turn OFF the manual shut -off valves of all gas
supply connections. This will extinguish the pilots.

The following tasks should be performed monthly:
1. Clean around burner air mixers and orifices if lint has accumulated in these areas.
2. Check for proper pilot operation. Check that the pilot flames are blue (with little or no yellow in the flame tips),
stable (not lifting off the pilots), and not producing carbon. If adjustment is necessary, call for service.
3. Check for proper burner operation. The burner flames should be blue and stable. If adjustment is necessary, call
for service.
SEMIANNUAL CLEANING AND MAINTENANCE
At least twice a year the venting system should be examined and cleaned.
STAINLESS-STEEL SURFACES
To remove normal dirt, grease and product residue from stainless steel surfaces that operate at LOW temperature,
use ordinary soap and water (with or without detergent) applied with a sponge or cloth. Dry thoroughly with a clean
cloth.
To remove BAKED-ON grease and food splatter, or condensed vapors; apply cleanser to a damp cloth or sponge and
rub cleanser on the metal in the direction of the polishing lines on the metal. Rubbing cleanser, as gently as possible,
in the direction of the polished lines will not mar the finish of the stainless steel. NEVER RUB WITH A CIRCULAR
MOTION. Soil and burnt deposits which do not respond to the above procedure can usually be removed by rubbing
the surface with SCOTCH-BRITE scouring pads or STAINLESS scouring pads. DO NOT USE ORDINARY STEEL

CLEANING &MAINTENANCE CHEF SERIES SECTIONAL RANGE
WOOL as any particles left on the surface will rust and further spoil the appearance of the finish. NEVER USE A
WIRE BRUSH, STEEL SCOURING PADS (EXCEPT STAINLESS), SCRAPER, FILE OR OTHER STEEL TOOLS.
Surfaces which are marred collect dirt more rapidly and become more difficult to clean. Marring also increases the
possibility of corrosive attack. Refinishing may then be required.
“Heat tint” is darkened areas that sometimes appear on stainless steel surfaces where the area has been subjected to
excessive heat. These darkened areas are caused by thickening of the protectiv e surfa ce of t he stainless steel and
are not harmful. Heat tint can normally be removed by the foregoing, but tint which does not respond to this procedure
calls for a vigorous scouring in the direction of the polish lines using SCOTCH-BRITE scouring pads or a STAINLESS
scouring pad in combination with a powered cleanser. Heat tint may be lessened by reducing heat to equipment
during slack periods.
BAKED-ENAMEL SURFACES
Allow appliance to cool somewhat after use and wash baked-enamel surfaces with a hot, mild detergent or soap
solution. In particular, clean off all grease deposits. Dry thoroughly with a dry cloth.
OPEN-BURNERS AND GRATES
The grates can be removed and cleaned with a solution of hot water and strong soap or detergent. The burners
themselves require little attention, but if spillage should occur, it may be necessary to clean around pilot areas, air
mixer and under burners. Use a wire brush if necessary. Periodically, open-burners sho uld be removed and cleaned.
Allow the interior of the burner to drain, and dry thoroughly before replacing.
HOT-TOP SURFACES
Before cleaning hot-top surfaces, allow them to cool. If water is used on hot-tops while they are still hot, they may
crack, so avoid this practice. The hot-top plates can be removed and cleaned with hot water and detergent. A wire
brush may be used on the underside of the hot top plate. It is recommended not to clean tops while still on the range,
even if cooled, as excess water will drip into the burner box and deteriorate the metal.
CARE OF GRIDDLES
A griddle should be carefully cared for in order to avoid possible damage. (The griddle should have been tempered as
part of the installation procedure, see page
any type of steel wool. Small particles may be left on the surface and get into food products. Do not clean spatula by
hitting the edge on the griddle plate. Such action will only cut and pit the griddle plate, leaving it rough and hard to
clean.

OVEN INTERIOR
WARNING
FOR YOUR SAFETY, DISCONNECT THE POWER SUPPLY TO THE SECTIONAL RANGE BEFORE
CLEANING THE OVEN. WHEN CLEANING THE BLOWER WHEEL OF A CONVECTION OVEN, BE SURE TO
HAVE THE POWER SWITCH IN THE “OFF” POSITION.
To clean the oven interior, first allow the oven to cool. Remove oven bottom and clean it by rubbing with strong
detergent and a Brillo pad or similar scrubber. “Spillovers” should be cleaned from the bottom as soon as possible to
prevent carbonizing and a “burnt-on” condition. For stubborn accumulations, commercial oven clea ners are
recommended.
The porcelain oven door lining can be cleaned in a similar manner. The side, rear and top lining should be wiped only
with a cloth dampened with a mild detergent and water. Avoid using excessive amounts of water, as this may drip into
burner compartment and deteriorate the metal in that area. Do not use strong commercial cleaners or abrasive pads
on the side, rear or top linings, as they may damage the finish or leave gray residue.

INSTALLATION
NOTICE
These installation procedures must be followed by qualified personnel or warranty will be void.
Local codes regarding installation vary greatly from one area to another. The National Fire Protection Association,
Inc., states in its NFPA 96 latest edition that local codes are the “authority having jurisdiction” when it comes to
installation requirements for equipment. Therefore, installations should comply with all local codes.
The installation must conform with local codes, or in the absence of local codes, with the National Fuel Gas Code,
ANSI Z223.1, Natural Gas Installation Code, CAN/CGA-B149.1, or the Propane Installation Code CAN/CGA-
B149.2, as applicable, including:
1. The appliance and its individual shutoff valve must be disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in excess of 1/2 psi (3.45 kPa).
2. The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve
during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psi (3.45
kPa).
NOTICE
EXHAUST FANS AND CANOPIES: It is recommended that the range be installed under a ventilation hood.
Consult local codes for proper installation of hoods. Proper ventilation is the owner’s responsibility. Any problem

STEP 1:UNPACKING
IMMEDIATELY INSPECT FOR SHIPPING DAMAGE
All containers should be examined for damage before and during unloading. The freight carrier has assumed
responsibility for its safe transit and delivery. If damaged equipment is received, either apparent or concealed, a
claim must be made with the delivering carrier.
Apparent damage or loss must be noted on the freight bill at the time of delivery. The freight bill must then be
signed by the carrier representative (Driver). If the bill is not signed, the carrier may refuse the claim. The carrier
can supply the necessary forms.
A request for inspection must be made to the carrier within 15 days if there is concealed damage or loss that is not
apparent until after the equipment is uncrated. The carrier should arrange an inspection. Be certain to hold all
contents plus all packing material.
For each section, do the following:
1. Cut the banding straps and remove the corrugated cardboard surrounding the section. (If legs, casters, a flue
riser, and/or shelf components were shipped in the same container, set them aside for installation in later steps
of this procedure. Do not remove any tags or labels attached to the range until the range is installed and working

2. Slide each flue riser down onto the brackets projecting from the back of the corresponding section(s) of the
sectional range. Secure the flue riser to the brackets with the four provided 1/4-20x3/4 hex-head bolts, flat
washers, and lockwashers. Also, secure the bottom edge of the flue riser to the top rear edge of the sectional
range using the provided #10 sheet metal screws.
3. If access to the interior of the flue riser is necessary to make gas connections, make those connections at this
time.
4. Attach each wall shield to the back of the corresponding flue riser using the provided #10 sheet metal screws.
5. Connect the top side edges of adjoining flue risers using the provided small plates and screws.
6. If tubed shelves were installed, place the tubes in place in the shelf brackets.
7. If sloped enclosures were ordered (for flue-mounted salamander broilers and/or cheese melters), install them at
this time.
STEP 6:CONNECT ELECTRICITY (FOR SECTIONS WITH OVEN-BASES)
A wiring diagram is located behind the kick panel of the oven-base ranges. Be sure that the input voltage and phase
match the requirements shown on the serial plate.
Oven-base ranges ordered with a 115V, 60Hz, single-phase electrical rating are factory-supplied with a three-wire
cord with a three-prong plug that fits any standard three-prong grounded receptacle. Each standard oven requires a
15 ampere supply, while each convection oven requires a 20 ampere supply.
Oven-base ranges ordered with a 208/236V, 60Hz, single- or three-phase electrical rating are factory-equipped with
a two-pole terminal block located behind cover plate located on the rear of the unit. To connect the supply wires,
remove the cover plate. Route the supply wires and the grounding wire through the strain relief fitting to the terminal
block. Insert the supply wires, one each, into the two poles of the terminal block and tighten the screws. Insert the
ground wire into the grounding lug and tighten the screw. Re-attach the cover plate.
Three phase units are wired as above, using only two supply wires. The third wire is not use d and must be properly
terminated.
All units are shipped wired as specified by factory order. Conversion between single-pha se and three-phase can be
accomplished by referring to phase loading and line amperes chart on the wiring diagram for wire size and ampere
requirements.
STEP 7:CONNECT GAS SUPPLY
If the sectional range is being installed at over 2,000 feet altitude and that information was not specified when
ordered, contact the appropriate authorized Lang Service Representative or the Lang Service Department. Failure to
install with proper orifice sizing will result in poor performance and may void the warranty.
The sectional range is design-certified for operation on natural or propa ne gases. The sectional range is shipped
configured and adjusted for the type of gas specified by the purchaser, which is indicated on the serial plate (see
Figure 1 on page 3). Connect the sectional range ONLY to the type of gas for which it is configured and adjusted.
Minimum supply pressure is 7" W.C. for natural gas, 11" W.C. for propane. An external pressure regulator and shut off
valve are provided. If using a flexible-hose gas connection, the I.D. of the hose must not be smaller than the
connector on the sectional range, and must comply with ANSI Z21.69. Provide an adequate m eans of restraint to
prevent undue strain on the gas connection.
If applicable, the vent line from the gas pressure regulator shall be installed to the outdoors in accordance with local
codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1, Natural Gas Installation Code, CAN/CGA-B149.1, or the Propane Installation Code CAN/CGA-B149.2, as applicable.
An adequate gas supply is imperative. Undersized or low pressure lines will restrict the volume of gas required for
satisfactory performance. A 1/8" pressure tap is located on the manifold to measure the manifold pressure. The
supply line to the sectional range should be no smaller than the inside diameter of the pipe on the se ctional range to
which it is connected.
CAUTION
ALL PIPE JOINTS AND CONNECTIONS MUST BE TESTED THOROUGHLY FOR GAS LEAKS. USE ONLY
SOAPY WATER FOR TESTING ON ALL GASES. NEVER USE AN OPEN FLAME TO CHECK FOR GAS LEAKS.
ALL CONNECTIONS MUST BE CHECKED FOR LEAKS AFTER THE APPLIANCE HAS BEEN PUT INTO
OPERATION. TEST PRESSURE SHOULD NOT EXCEED 14" W.C.
PAGE 26 OF 76 OWNER’S MANUAL 1192040 REV 1(01/10)

CHEF SERIES SECTIONAL RANGEINSTALLATION
Do the following to connect the gas supply:
1. Check that all control knobs on the sectional range are in the OFF position.
2. Purge the gas supply line to clean out dust, dirt, or other foreign matter before connecting the line to the sectional
range.
3. The gas connection piping may have been partially installed at the factory. If necessary, attach the gas
connection of any appliances mounted on a flue riser.
4. Locate the pressure regulator(s) packed with the sectional range. Install the pressure regulator, taking care that
the direction of gas flow corresponds to the arrow on the side of the pressure regulator.
CAUTION
HOLD THE PRESSURE REGULATOR WITH A WRENCH WHEN TIGHTENING THE CONNECTION TO THE
SUPPLY PIPE TO AVOID DAMAGE TO THE REGULATOR, VALVE, AND OTHER COMPONENTS.
5. Install a service shut-off valve to the pressure regulator, and connect the gas supply line to the shut-off valve.
6. If applicable, install the vent line of the pressure regulator to the outdoors.
7. Turn on the gas and immediately check for leaks using soapy water.
8. If the optional sloped enclosure for a flue-mounted model was ordered, install it at this time.
STEP 8:CONNECT WATER SUPPLY
If a rail-mounted fill-hose was ordered (as a special option), there will be a corres ponding water connection on the
back of the section. Connect the water supply.
STEP 9:CHECK THE INSTALLATION

6. Begin to break-in all griddle surfaces by turning on all griddle burners to LOW for at least one hour. (In case any
problems occur, do not leave the battery unattended during this time!) This will temper the griddle surface and
avoid possible damage.
7. Check operation of all sections (except griddles) for the full-range of operating settings, including checking all
burners for correct flame appearance and height at the HIGH settings.
8. Complete the break-in of all griddle surfaces (after they have been operating at LOW for at least one hour) by
gradually bringing each griddle up to frying temperature. Then spread over each griddle three or four o unces of
beef suet, or as a substitute, baking soda, to season it. Never allow water on a hot griddle and never wash it with
soap and water.
9. Check that gas supply is adequate by simultaneously turning on all burners of all sections to their highest setting,
then again checking that all burner flames have correct appearance and height.
10. Check that electricity supply is adequate by simultaneously turning on all electrical elements (if any) and turning
the blower setting of all convection ovens (if any) to HIGH.
11. Check that water supply is adequate by simultaneously operating all fill hoses (if any). (Do not allow water to
spill onto a hot griddle.)
12. Turn-off all burners and allow all battery sections to cool.

TROUBLESHOOTING BURNERS AND PILOTS
The following table lists the possible causes of burner and pilot related problems that may occur.
Problem Look for -
None of the burners and pilots will turn on – Main gas supply to unit is OFF.
All burners produce excessive carbon deposits – Incorrect gas type is being supplied to the range.
– Incorrect gas supply pressure.
Only some burners produce excessive carbon deposits – Incorrect orifices.
– Primary air not adjusted properly.
Only some pilots produce excessive carbon deposits – Pilot not adjusted properly.
– Incorrect pilot orifice.
Top burner (not oven) will not come on – Pilot out.
– For thermostatic griddles, gas shut off valve is in OFF position.
– For thermostatic griddles, button on safety switch is not being
held in long enough after lighting pilot.
Top section pilot will not remain lit – Pilot flame not adjusted properly.
– Clogged orifice.
– Draft condition.
– Improper ventilation system.
– Air in gas line.
SERVICING BURNERS AND PILOTS
All orifice sizes and burner rates are properly set at the factory and sho uld not be altered.
Each burner should have a steady blue flame on each port of the burner. When using propane, the burners may have
a small amount of yellow tipping.
If the flame is rising up off of the ports adjust the burner shutter to be further closed. If the flame is long and yellow
adjust the burner shutter to be further open.
Over-gassed burners DO NOT heat as efficiently as those that are properly adjusted. Such conditions also create “hot
spots” on griddles and hot tops. Floating and unstable burner and pilot flames will result when solid tops are l owered
into position because the rear openings of the burner compartment are not adequate to vent the enormous flue
products generated by over-gassed burners. The “unburned” gas will ignite at the rear and burn in this section and
even up inside the flue riser, causing structural members in this area to deteriorate. Also, some of these hot flue
products will vent forward into the manifold compartment resulting in problems with valves and thermostats due to
overheating. AGAIN, over-gassed burners waste energy and cause service problems.
Note that the burners of griddle, charbroiler, and uniform hot-top models are long, and so the burner flame may float
when cold. Allow the burner to heat before making burner adjustments.
Propane burners may have a slight popping noise when turned off. This is normal.
Check that the burner is level and in its support brackets.
Check that the burner is clean and all of its ports are clear.
Check that each burner valve and orifice is in alignment with the burner.
Remove the burner and check that its venturi is clean and free of buildup and debris.
With each burner removed check that the orifice size is correct and clean and free of buildup and debris.
If it is necessary to remove a griddle top to service the burners, use extreme care since the griddle plate is very
heavy. When raising a thermostatic griddle top, remove the thermostat bulbs from the tubes on the bottom of the
griddle plate. When re-installing, re-insert the thermostat bulbs and be sure the capillary tubes are away from burners,
flames and excessive heat.
Pilot-flame outage is often due to an unstable flame caused by over-adjustment to the point where the pilot flame is
leaving its port, or “blowing off.” Sometimes the pilots are increased too much in an effort to improve ignition, resulting
in this unstable condition.

Adjustment of Charbroiler, Standard-Griddle, and Uniform Hot-Top Burners and Pilots
The burner valves are not adjustable. The burner orifice is of the fixed type, sized for the type of gas and the operating altitude.
To adjust the burner air-gas mixture, loosen the screw that secures the air shutter on the mixer face and rotate the mixer cap
to obtain a clear, stable blue flame with a distinct inner cone at each port. Excessive primary air causes “blowing” (the flames
leaving the ports), while insufficient primary air causes a soft or yellow tipped flame.
The pilots are near the front of the burners, and are held in position by brackets. To adjust a pilot flame, insert a screwdriver
through the opening in the valve panel between the control knobs and turn the appropriate pilot adjustment screw
counterclockwise to increase the size of the pilot flame, or clockwise to decrease the size of the pilot flame. The maximum
flame size is approximately 3/4" with a slight yellow tip. The first indication of over-adjustment is when the flame tip becomes
more yellow and begins to generate carbon, which appears as rising black streaks. Continued over-a djustment leads to
unstable lifting and a blowing condition.

Adjustment of Thermostatic-Griddle Thermostat
Each 12"-wide section of a thermostatic griddle has a control knob that operates a snap-action thermostatic valve. Each valve
is adjusted at the factory. If the griddle surface temperature is different from the thermostat dial setting, adjust the thermostatic
valve using the following procedure:
1. Turn all the control knobs to the 300°F.
2. Wait 30 minutes for the griddle temperature to stabilize (or 1 hour if the griddle was cold).
3. Place a reliable thermometer or test-instrument thermocouple (able to register 300°F) halfway back from the front to the
back of the griddle and directly in line with the 12"-wide section’s control knob (see drawing below). Check the temperature
of each section every five minutes until the temperature does not change by more than 30°F bet ween two consecutive
measurements.
4. If the average temperature of any section is not within 30°F of the knob setting (300°F), adjust the corresponding
thermostatic valve. To do so, remove the control knob (being careful to not turn the stem, which would change the
temperature setting). While holding the stem in place, turn the calibration screw (see drawing below). If the actual
measured temperature is lower than the dial setting, turn the screw counterclockwise. If the measured temperature is
higher than the dial setting, turn the screw clockwise. Replace the control knob.
5. Wait for the griddle temperature to stabilize, then again check the temperature (as described above).
Measure temperature of each 12"-wide section
half-way back and in line with control knob.
Each knob is attached to a thermostatic
valve located behind the valve panel.
With a control knob removed,
its valve shaft will extend out
of the valve panel.

Adjustment of Oven Thermostat
The oven thermostat is carefully calibrated at the factory so that the dial setting matches the actual oven temperature. Field
recalibration is seldom necessary, and should not be resorted to unless considerable cooking e x perience definitely proves that
the control is not maintaining the temperatures to which the dial is set.
Obtain a test instrument or a reliable mercury thermometer, then do the following:
1. Place the thermocouple of test instrument or the thermometer in the middle of the oven.
2. Turn on the oven and set the thermostat to 400°F.
3. After the oven has been on about 20 minutes check oven temperature. The oven door should be open for as short a time
as possible. Use a flashlight, if necessary, to see the thermometer clearly.
4. Continue to check the temperature at 5-minute intervals until two successive readings are within 5 degrees of each other.
The thermostat should be recalibrated if the reading is not within 20 degrees of the dial setting (400°F ). If calibration is
required, adjust the thermostat, as follows:
5. Remove the oven temperature control knob. Be careful to not turn the stem (which would change the temperature setting).
6. While holding the stem in place, turn the calibration screw (see drawing below). If the actual measured temperature is lower
than the dial setting, turn the screw counterclockwise. If the measured temperature is higher than the dial setting, turn the
screw clockwise. Replace the control knob.
7. Set the oven temperature to 450°F. After about 20 minutes, check the oven temperature. Continue to check the
temperature at 5-minute intervals until two successive readings are within 5 degrees of each other. If the actual oven
temperature is not within 20 degrees of the dial setting (450°F), replace the thermostat.

Adjustment of Oven Pilot and Burner
The burner orifice is of the fixed type, sized for the type of gas and the operating altitude. To adjust the burner air-gas m ixture,
loosen the screw that secures the air shutter on the mixer face and rotate the mixer cap to obtain a clear, stable blue flame
with a distinct inner cone at each port. Excessive primary air causes “blowing” (the flames leaving the ports), while insufficient
primary air causes a soft or yellow tipped flame.
The oven pilot flame is adjusted by using a screwdriver to turn the adjusting screw on the pilot line valv e (see drawing below).
The pilot line valve is located behind the kick panel below the oven door. To gai n access, lift the kick panel straight up and pull
the top edge out. The pilot flame is properly adjusted when it is just large enough to maintain a glowing red color of the
thermopile capillary bulb. The first indication of over-adjustment is when the flame tip becomes yellow and begins to generate
carbon, which appears as rising black streaks. Continued over-adjustment leads to unstable lifti ng and a blowing condition.

ADJUSTMENT OF MANIFOLD GAS PRESSURE
There is not an internal pressure regulator. The external pressure regulators supplied by Lang are factory set at 6"
W.C. for natural gas and 10" W.C. for propane gas. To check the manifold pressure, do the following:
1. Turn OFF all thermostats, burner controls, gas shut-off valves, and the external gas supply connection(s).
2. Remove the valve panel and locate the 1/8" plug in the front manifold furthest from the gas connection location.
Remove the plug and install a fitting appropriate to connect a manometer.
3. Turn ON all gas supply valves and light all pilots.
4. Turn all burners and ovens to full ON position and read manometer.
5. If manometer does not read 6" W.C. for natural gas (or 10" W.C. for propane gas) adjust regulator by removing
the cap from the top of regulator. Use a screwdriver to rotate the regulator adjustment screw clockwise to
increase pressure, or counterclockwise to decrease pressure, until manometer shows correct reading.
6. Turn OFF all thermostats, burner controls, gas shut-off valves, and the external gas supply connection(s).
7. Remove manometer fitting and replace plug in manifold.
8. Turn ON all gas valves and light all pilots.
