GAS SUPPLY
The serial plate is located on the interior side of the valve panel (see Figure 1 on page 3). It indicates the
type of gas the unit is equipped to burn. All Southbend equipment is adjusted at the factory. Check type of
gas on serial plate.
These models are design-certified for operation on natural or propane gases. The unit is shipped
configured for the type of gas specified by the purchaser. A kit for conversion to a different type of gas may
This appliance should be connected ONLY to the type of gas for which it is configured.
An adequate gas supply is imperative. Undersized or low pressure lines will restrict the volume of gas
required for satisfactory performance. Fluctuations of more than 25% on natural gas or 10% on propane
gas will create problems and affect burner operating characteristics. A 1/8" pressure tap is located on the
manifold to measure the manifold pressure.

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 units must be installed in such a manner that the flow of combustion and ventilation air are not
obstructed. Provisions for adequate air supply must be provided. Do not obstruct the front of the unit
at the top by the control panel 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.
Air for combustion enters the rear of the appliance. An exhaust flue runs along the top rear edge of griddle
and charbroiler models.
Southbend recommends that a ventilation canopy extend 6" past the edges of the appliance and be located
6'6" above the floor.
If a wall exhaust fan is installed in the wall behind the appliance, it should be at least two feet above the top
of the appliance.
To avoid a negative pressure condition, return air must be brought into the room to replenish the air being
removed by the ventilation exhaust fan. RETURN-AIR FANS MUST NOT BLOW DOWN ONTO THE
APPLIANCE.
Ventilation filters should be installed at an angle of 45° or more from the horizontal. This prevents dripping
grease and facilitates collecting the run-off grease in a drip pan, usually installed with a filter.
Be sure to inspect and clean the ventilation system according to the ventilation equipment manufacturer’s
instructions.
In case of unsatisfactory performance on any appliance, check the appliance with the ventilation exhaust
fan in the “OFF” position. Do this only long enough to check equipment performance. Then turn the fan
back on and let it run to remove any exhaust that may have accumulated during the test.

Step 4: Connect Gas Supply
The serial plate is located interior side of the control panel (see Figure 1 on page 3). It indicates the type of
gas the appliance is equipped to burn. All Southbend equipment is adjusted at the factory. Check type of
gas on serial plate. This appliance should be connected ONLY to the type of gas for which it is equipped.
If the appliance is being installed at over 2,000 feet altitude and that information was not specified when
ordered, contact the appropriate authorized Southbend Service Representative or the Southbend Service
Department. Failure to install with proper orifice sizing will result in poor performance and may void the
warranty.
These models are design-certified for operation on natural or propane gases. For natural gas, the
convertible regulator shipped with the appliance is set to deliver a 4" W.C. pressure to the manifold. For
propane gas, it is set to deliver 10" W.C.
An adequate gas supply is imperative. Undersized or low pressure lines will restrict the volume of gas
required for satisfactory performance. Fluctuations of more than 25% on natural gas or 10% on propane
gas will create problems and affect burner operating characteristics. A 1/8" pressure tap is located on the
manifold to measure pressure.
Purge the supply line to clean out dust, dirt, or other foreign matter before connecting the line to the
appliance.
Use pipe joint compound that is suitable for use with LP gas on all threaded connections.
! 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.
To connect the gas supply, do the following:
1. Check that the gas supply to the piping that will be connected to the appliance is shut off.
2. Check that the manual shut-off valve inside the front panel door of the appliance is closed (60" and 72"
models have two shut-off valves).
3. Check that all control knobs on the appliance are turned “OFF.”
4. Attach the pressure regulator shipped with the appliance to the 3/4" NPT gas inlet connector located on
the rear of the appliance (see Figure 4 below). Be sure that the regulator is connected so that the gas
flow is in the same direction as the arrow on the bottom of the regulator.
5. Connect the vent line from the pressure regulator 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.
6. Connect the gas inlet of the pressure regulator to the building’s supply system. No segment of the gas
supply connection to the appliance should be smaller than 3/4" NPT. Standard pipe fittings are
required.
7. Turn on gas supply.
8. Check for leaks using soapy water.

DANGER
EXPLOSION HAZARD
Purchaser of equipment must post in a prominent location, detailed instructions to be followed in the
event the operator smells gas. Obtain the instructions from the local gas supplier.
! CAUTION
To eliminate gas build up which could result in an explosion, in the event of main burner ignition
failure a five minute purge period must be observed prior to re-establishing ignition source.
! CAUTION
Top section pilots, when out, do not interrupt the flow of gas to the burners. Consequently, it is the
responsibility of the operator to check the ignition of the burners, immediately after burner value has
been turned “ON.” Should ignition fail after 10 seconds, turn off burners, wait 5 minutes, and then try
again.
! WARNING
UNDER NO CIRCUMSTANCES IS A GRIDDLE TO BE USED FOR HEATING STOCK POTS. SUCH
USE AUTOMATICALLY VOIDS THE WARRANTY.
NEVER COOL A GRIDDLE BY APPLYING ICE OR WATER TO THE GRIDDLE SURFACE.
DAMAGE DUE TO MISUSE IS NOT COVERED BY THE WARRANTY.
DO NOT STRIKE A GRIDDLE SURFACE WITH THE EDGE OF COOKING IMPLEMENTS TO
CLEAN THE IMPLEMENTS. SUCH ACTION WILL CUT AND PIT THE GRIDDLE PLATE, LEAVING
IT ROUGH AND HARD TO CLEAN.
ALWAYS HEAT A GRIDDLE SLOWLY. DO NOT HEAT A GRIDDLE ABOVE 550°F.
LIGHTING AFTER GAS HAS BEEN SHUT OFF
When turning the main gas supply on after the gas supply has been shut off, do the following:

OPERATION OF THERMOSTATIC GRIDDLE MODELS
Each 12"-wide griddle section has a thermostatic-control knob on the front panel that directly controls the
flow of gas, and so the heat. Turn the knob clockwise to increase the heat; turn it counterclockwise to
reduce the heat.
The griddle requires approximately 13 minutes of preheating to reach 350°F, and 45 minutes to even out.
Do not waste gas or abuse equipment by leaving control knobs set at a high temperature if not required.
During idle periods, set control knobs to low temperature settings to keep griddle warm.
After each period of use, allow the griddle surface to cool normally. At the end of each day’s use, turn all
control knobs to the “OFF” position. After the griddle has cooled, coat the griddle surface with a light film of
cooking oil to protect the surface from moisture.
To shut down the appliance for an extended period (or before disconnecting the gas supply), turn all the
burner control gas knobs “OFF,” then turn the main gas supply valve(s) to “OFF.”
To light the pilots of a thermostatic griddle section, do the following:
1. Turn all griddle controls to the “OFF” position.
2. Open the grease/control door at the bottom of the front of the griddle.
3. Turn the main shut-off valve to the “ON” position (if it is not already ON). (Note that 60" and 72" models
have two shut-off values, one in each burner compartment.)
4. Note that the left pilot must be lit before the right pilot can be lit. For each pilot, press and hold the
red pilot button and light the pilot by pressing the electronic ignition button on the front panel to
generate a spark. Continue to hold the pilot button for 45 seconds, or until the pilot remains lit. Note
that 24" models have one pilot, 36" & 48" models have two pilots, 60" models have three pilots, and 72"
models have four pilots.
5. If a pilot is extinguished or the gas supply is interrupted, wait five minutes and repeat the above steps.
6. Allow the pilots to warm-up for 1 minute, then turn all griddle thermostat controls to the “ON” position to
check that the pilots will ignite the burners.

OPERATION OF CHARBROILER MODELS
Each 6"-wide charbroiler section has a knob on the front panel that directly controls the flow of gas, and so
the heat. Turn the knob counterclockwise to increase the heat; turn it clockwise to reduce the heat.
To use the charbroiler, turn all the control knobs to the full “ON” position. (If any burners do not light, check
the pilots and, if necessary, light the pilots as described later in this section.) After 15 to 20 minutes turn
back the flame to maintain enough heat to keep the bottom of the radiants or lava-rock grates hot. The
radiants or grates will be at broiling temperature throughout, providing the radiant heat that is essential to
provide fast broiling.
By design, the rear two-thirds of the broiler grid is much hotter than the front third. Use the rear of the
charbroiler to quickly sear both sides of meat to retain maximum juices. This fast cooking is one of the
secrets of successful meat broiling, and gives the meat that special “outdoor” flavor. Cook rare meats at the
back quickly; cook medium and well-done meats closer to the front more slowly. Adjust the cooking time
according to the thickness of the meat and amount of doneness desired. If desired, move meat cooked rare
to the very front to keep it warm while medium and well-done meats are still cooking. Remember that to
cook meat properly you must keep in mind both heat and time.
The tilt angle of the charbroiler grid is adjustable by pulling up on the back of the grid. The tilted position is
normal and recommended. The tilt angle allows most fat rendered off meat during broiling to run into the
grease trough, thus eliminating excess flaring of fats and accompanying smoke. Steaks and chops, being
fattier than other meats, will still have some flaring up to give the desired broiling results while enough fat
drains off to avoid severe flares. Use the flat position for heating on the top, or for continuous cooking of hot
dogs and sausage. Fats dripping down into the fire will burn up on the meat to help give it that desirable
special flavor.
The heavy cast iron grids can be turned over for different “branding” width. One side has wide-branding
(1/4") and the other side has narrow branding (1/8" with grease channel). Chrome-plated grids can be
ordered for cooking fish.
At the end of each day’s use, turn all knobs to the “OFF” position.
To shut down the appliance for an extended period (or before disconnecting the gas supply), turn all the
burner control gas knobs “OFF,” then turn the main gas supply valve to “OFF.”
To light the pilot(s) of a charbroiler section, do the following:
1. Turn all control knobs to the “OFF” position.
2. Light the pilot located next to each burner (accessed through front). If the pilot will not remain lit, have a
service technician adjust the pilot by turning the screw on the pilot fitting.
3. Turn burner knobs to “HI” position. The burners should have a 1/2" to 5/8" steady blue flame. If they do
not, have them adjusted by a service technician.
4. To turn burners off, turn knob to “OFF” position.

CLEANING
HEAVY DUTY COUNTERLINE
CLEANING
Southbend equipment is constructed with the best quality materials and is designed to provide durable
service when properly maintained. To expect the best performance, your equipment must be maintained in
good condition and cleaned daily. Naturally, the frequency and extent of cleaning depends on the amount
and degree of usage.
Daily:
• Remove, empty, and clean grease drawers of griddles and charbroilers.
• Clean griddle drain chutes of griddles.
Monthly:
• Clean around burner air mixers and orifices if lint has accumulated.
• Visually assure proper pilot operation.
CARE OF CARBON STEEL GRIDDLE SURFACE
Never allow water on a hot griddle and never wash it with soap and water.
Use a Norton Alundum Griddle Brick to clean the griddle. Always remember to heat a griddle slowly
because quick heat may cause costly damage. Griddle plates cannot be guaranteed against damage due
to carelessness. Never place utensils on griddle. Do not overheat griddle above 550°F as this will cause
warpage or breakage.
Do not use any type of steel wool. Small particles may be left on the surface and get into food products. Do
not clean a 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.
CARE OF CHROME PLATED GRIDDLE SURFACE
Allow griddle plate to cool down to approximately 200°F. Pour 8 ounces of water onto griddle surface.
Apply a non-abrasive degreaser to water on griddle surface. Using a non-abrasive brush, evenly spread
degreaser solution around entire griddle plate surface and use additional water if necessary to cover entire
griddle plate. Allow time to soak until grease begins to separate. Using a non-metallic scraper, remove
remaining grease particles from the griddle surface. Flush the entire griddle surface with clean water until
all degreaser solution has been removed. Wipe he entire griddle surface, back and splash walls with a
clean damp cloth.
CARE OF STAINLESS STEEL SURFACES
To remove normal dirt, grease and food residue from stainless steel that operates 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 grease, food splatter, or condensed vapors that have BAKED onto the equipment, apply
cleanser to a damp cloth or sponge and rub cleanser on the metal in the direction of the polishing lines on

CLEANING
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 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 that 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 a darkened area that can appear on a stainless steel surface where the area has been
subjected to excessive heat. These darkened areas are caused by thickening of the protective surface of
the 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 action may be lessened by not applying, or by reducing heat to equipment during slack periods.

NOTICE
The warranty will be void and the manufacturer relieved of all responsibility if…
(A) Service work is performed by other than a qualified technician, or
(B) Other than genuine Southbend replacement parts are installed.
Before making any adjustment, make sure the appliance is connected to the type of gas for which it is
equipped. That information is on the serial plate, which is located on the inside of the control panel (see
ADJUSTMENT OF MANIFOLD GAS PRESSURE
A pressure regulator is connected to the appliance’s gas connection, outside the rear left corner of the
appliance. The pressure regulator is factory set at 4" W.C. for natural gas and 10" W.C. for propane. To
check the manifold pressure, do the following:
1. Turn all burner valves to “OFF” position.
2. Turn main gas valve to entire appliance off.
3. Remove front panel and locate 1/8" plug in manifold. (Note that 60" and 72" griddle models have two
burner compartments, and so have two manifolds.)
4. Remove the plug and install a fitting appropriate to connect a manometer.
5. Turn on main gas to appliance and light pilots.
6. Turn all burners to full “ON” position and read manometer.
7. If manometer does not read 4" W.C. for natural gas (or 10" W.C. for propane gas), check the incoming
gas line for proper pressure. The proper gas line pressure is 5-7" W.C. for natural gas and 11-14" W.C.
for propane.
8. Remove manometer fitting and replace plug in manifold.
9. Replace front panel.
10. Turn on main gas to appliance and light pilots.

ADJUSTMENT OF PILOT FLAME (GRIDDLE MODELS)
The pilots are adjusted at the factory. If later the pilots are over-adjusted to the point where the flame is
leaving its port, or “blowing off,” the result is an unstable condition in which the pilot may extinguish. If
necessary, adjust each burner’s pilot using the following procedure:
1. Open the door on the lower front of the appliance, remove the control knobs, and remove the control
panel by removing the screws holding it in place.
2. If necessary, light the pilots.
3. Locate the adjustment valve of the pilot that needs adjustment (see Figure 7 below). On thermostatic
griddles, the valve is in the pilot’s supply line, while on manual griddles the valve connects the pilot’s
supply line to the front manifold. Turn the pilot adjustment screw to the left to increase the size of the
pilot flame, or to the right to decrease the size of the pilot flame. The flame should be about 1/2" high
with a slight yellow tip, and cover the thermocouple tip. The flame is too high if the yellow tip is
producing black streaks of carbon.
4. Repeat Step 3 for each pilot.
5. Replace the control panel and knobs.

ADJUSTMENT OF PILOT FLAME (CHARBROILER AND OPEN-TOP MODELS)
The pilots are adjusted at the factory. If later the pilots are over-adjusted to the point where the flame is
leaving its port, or “blowing off,” the result is an unstable condition in which the pilot may extinguish. If
necessary, adjust each burner’s pilot using the following procedure:
1. If necessary, light the pilots.
2. Locate the pilot adjustment valve (see Figure 8 below). Turn the pilot adjustment screw to the left to
increase the size of the pilot flame, or to the right to decrease the size of the pilot flame. The flame
should be about 1/2" high with a slight yellow tip. The maximum pilot flame height is 3/4". The flame is
too high if the yellow tip is producing black streaks of carbon.
4. Repeat Step 3 for each pilot.
5. Replace the control panel and knobs.

ADJUSTMENT OF BURNER FLAME
The burners are adjusted at the factory. If necessary to adjust the burner flames, do the following for each
burner:
1. Turn the burner’s control knob to the full ON position.
2. If the appliance was cold, wait 5 minutes before adjusting the burner flame.
3. Loosen the set screw that holds the sheet-metal air shutter in place.
4. If the burner flame is blowing or lifting off the burner ports, close the air shutter until a stable flame is
obtained. If the flame is yellow-tipping, open the air shutter until a stable blue flame is obtained (a small
amount of yellow-tipping is normal when using propane gas).
5. Tighten the set screw that holds the sheet-metal air shutter in place.
6. Repeat Steps 1 through 5 for each burner.
When adjusting the burners of griddle models, note that over-gassed burners DO NOT heat griddles as
efficiently as those that are properly adjusted and also create “hot spots” on the griddle surface. Floating
and unstable burner and pilot flames will result when solid tops are lowered 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 backguard or shelf venting system, 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-rated burners waste energy and cause service problems.
CONVERSION FROM ONE TYPE OF GAS TO ANOTHER
Each appliance is shipped gas-specific either for use with natural gas or for use with LP gas (propane). To
convert an appliance from one type of gas to another, do the following:
1. Remove the front panel by removing the knobs and screws on the front.
2. For each burner, replace the orifice with the type appropriate for the type of gas that will be used. For
special gas mixtures, and for altitudes above 2,000 feet, consult factory for appropriate orifice sizes.
3. For griddle models only, replace all the pilot assemblies.
4. Re-install the front panel.
5. Remove the hex-threaded plug from the pressure regulator (on the rear of the appliance). Inside is a
removable insert. Pull the insert out, turn it around, and put it back in so that the end facing out has the
letters corresponding to the type of gas that will be used (“NAT” or “LP”). Re-attach the hex-threaded
plug.
Note: A kit for conversion to a different type of gas may be purchased from Southbend.

ADJUSTMENTS
ADJUSTMENT OF GRIDDLE THERMOSTATS
Each burner’s control knob operates a snap-action thermostatic valve that was adjusted at the factory. If
the griddle surface temperature is different from the thermostat dial setting, adjust the valve using the
following procedure:
1. Turn all the control knobs to the 300°F.
2. Wait 30 minutes (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 over a burner (in line with the burner’s control knob,
see Figure 9 below). Check the temperature over each burner every five minutes until the temperature
over each burner stabilizes and does not change by more than 30°F between two consecutive
measurements.
4. If the average temperature over any burner is not within 30°F of the knob setting (300°F), adjust the
corresponding thermostatic valve. To do so, remove the knobs and control panel, adjust the calibration
screw on the thermostatic valve (see Figure 9 below), replace the knobs and control panel, then repeat
Step 3.
Figure 9
Measure each temperature
halfway back from front to
back and directly over the
corresponding burner (in line
with the control knob).
Calibrate the valve using the Thermostat Calibration
Screw located at the base of the stem. Turn the
screw counterclockwise to increase the temperature,
or clockwise to decrease the temperature.
