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 ranges 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 range at the top by the control
panel, or the bottom just below the oven compartment, 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.
All ranges must be installed in such a manner that the flow of combustion and ventilation air are not obstructed.
Provisions for an adequate air supply must be provided. Do not obstruct the front or rear of the range, as
combustion air enters through this area. Be sure to inspect and clean the ventilation system according to the
ventilation equipment manufacturer’s instructions.
Canopies are set over ranges, ovens, etc., for ventilation purposes. It is recommended that a canopy extend 152 mm
past the appliance and the bottom edge be located 200 cm 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, unusually installed with a 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 51 mm above the vent opening at the top of the range.
If the range is connected directly to an outside flue, a CE design-certified down draft diverter must be installed at the
flue outlet of the oven and connected to the flue.
In case of unsatisfactory performance on any appliance, check the appliance with the exhaust fan in the OFF position.
Do this only long enough to check equipment performance. Then turn hood back on and let it run to remove any
exhaust that may have accumulated during the test.
GAS SUPPLY
A 3/4" female NPT gas connection is located on the rear of the range (see Figure 2).
The serial plate is located on the right side of the range (See Figure 1). The serial plate indicates the type of gas the
range is equipped to burn. All Southbend equipment is adjusted at the factory. Check type of gas on serial plate.
Number of Burners and Gas Requirement per Burner
Model Number Open Top Burners Oven Burner(s) Total Gas Requirement*
436A-CE 6 @ 32,000 BTU/hour (9.4 kilowatts) 1 @ 45,000 BTU/hour (13.2 kilowatts) 237,000 BTU/hour (69.5 kilowatts)

* Rated gas-requirement values are for natural gas.
These models are design-certified for operation on natural or propane gases. For natural gas, the regulator is set to
0.99 kPa (4" W.C.). For propane gas, it is set to 2.48 kPa (10" W.C.).
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 applicable national codes.
This appliance should be connected ONLY to the type of gas for which it is equipped.
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
PAGE 6OF 40 OWNER’S MANUAL 1182499

MODEL 400-CE RESTAURANT RANGES SPECIFICATIONS
and affect burner operating characteristics. A 1/8" pressure tap is located on the manifold to measure the manifold
pressure.
An adequate gas supply line to the range should be no smaller than the inside diameter of the pipe from the range to
which it is connected.
Purge the supply line to clean out dust, dirt, or other foreign matter before connecting the line to the range.
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 range has
been put into operation. Test pressure should not exceed 3.47 kPa (14" W.C.).
ELECTRICAL REQUIREMENTS
Ranges with a convection oven require connection to a supply of electricity. The appliance, when installed, must be
electrically grounded in accordance with local codes, or in the absence of local codes, with the applicable national
codes. An electrical diagram is located on the rear of the range, near the motor.
Convection-oven models are rated for 208/230 volts, 50/60Hz, 1-phase power, and have one or two junction boxes
(one for each oven) on the rear of the range (each with a terminal block). The maximum power requirement per oven
is 2.1 amperes at 208 volts or 2.5 amperes at 230 volts.

CLEANING & MAINTENANCE
WARNING
Shut off the range and allow time for it to cool before cleaning or performing maintenance.
Southbend appliances are sturdily constructed of the best materials and are designed to provide durable service when
treated with ordinary care. To expect the best performance, your equipment must be maintained in good condition and
cleaned daily. Naturally, the periods for this care and cleaning depend on the amount and degree of usage.
Following daily and periodic maintenance procedures will enhance long life for your equipment. Climatic conditions
(such as salt air) may require more thorough and frequent cleaning or the life of the equipment could be adversely
affected.
Keep exposed, cleanable areas clean at all times.
DAILY CLEANING
1. Turn all controls to OFF and allow time for the range to cool.
2. Remove, empty, and clean drip trays.
3. Wipe clean all cooking surfaces.
CLEANING OVEN INTERIOR
WARNING
FOR YOUR SAFETY, BEFORE CLEANING A CONVECTION OVEN DISCONNECT THE POWER SUPPLY.
WHEN CLEANING THE BLOWER WHEEL, BE SURE THAT THE POWER SWITCH IN THE “OFF” POSITION.
Allow oven to cool. Remove porcelain enameled oven bottom. Clean by rubbing with strong detergent and Brillo pad
or similar scrubber. “Spill-overs” should be cleaned from the bottom as soon as possible to prevent carbonizing and a
“burnt-on” condition. For stubborn accumulations, commercial oven cleaners 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.
PERIODIC CLEANING AND MAINTENANCE
At least monthly, clean around burner air mixers and orifices if lint has accumulated and visually check proper pilot
operation.
At least twice a year, examine and clean the range hood and venting system.
If range-top spillage should occur, it may be necessary to clean around pilot areas, air mixer, and under burners. Use
a wire brush if necessary.
If any burners become clogged, remove and clean them. Allow interior to drain. Dry thoroughly before replacing.
BLACK BAKED-ENAMEL SURFACES
Wash exterior black baked-enamel surfaces with a hot, mild detergent or soap solution to clean off all grease
deposits. Dry thoroughly with a dry cloth.
OWNER’S MANUAL 1182499 PAGE 11 OF 40

CLEANING & MAINTENANCE MODEL 400-CE RESTAURANT RANGES
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
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 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 may be lessened by reducing heat to equipment
during slack periods.

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.
Do the following:
1. Cut the banding straps and remove the corrugated cardboard surrounding the range. If legs 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 properly.
2. Lift the flue riser off the front of the skid (see Figure 3) and set it aside for installation later in this procedure.
3. Pull the shelf assembly out from under the base and set it aside for installation later in this procedure.
4. Unbolt the shipping hold-down brackets from the skid, then remove the brackets from the range.
5. If the range is to be installed on legs, go to Step 2a.
If the range is to be installed on casters, go to Step 2b.

STEP 2B: ATTACH CASTERS AND RESTRAINT
NOTICE
For an appliance equipped with casters, (1) the installation shall be made with a connector and a quick-
disconnect device that complies with the applicable local or national codes, (2) adequate means must be
provided to limit the movement of the appliance without depending on the connector and the quick-disconnect
device or its associated piping to limit the appliance movement, and (3) the restraining means should be
attached to a frame member on the back of the range.
A set of four casters is packed with ranges ordered with casters (instead of legs).
A threaded leg pad is fastened to the base frame at each corner. Each caster has a corresponding mating thread. The
casters can be adjusted to overcome a slightly uneven floor. Casters are provided with a Zerk fitting for proper
lubrication when required.
1. Raise range sufficiently to allow leg pads and casters to be attached. For safety, “shore up” and support the
range with an adequate blocking arrangement strong enough to support the load.
2. Attach the four leg pads to the bottom of the range using the lock washers and machine screws. The
mounting holes are pre-drilled and threaded.
3. Screw the casters into the holes in the centers of the leg pads. Install the casters that have a locking brake
under the front of the range.
4. Lower range gently onto a level surface. Never drop or allow the range to fall.
5. Use a level to make sure that the range surface is level. The casters can be screwed in or out to lower or raise
each corner of the range. After the range has been leveled, tighten the lock nuts.

6. Secure the restraining-device bracket (item “B” in the following illustration) to a wall stud located as close as
possible to the appliance connector inlet and outlet connections. Use four #12 screws (items “C”) and plastic
anchors (items “A”) if necessary.
7. Install eye-bolt (item “F”) to a frame member on the rear of the equipment. After checking carefully behind the
frame member for adequate clearance, drill a 7 mm hole through the frame member.
8. Thread hex nut (item “G”) and slide the washer (item “H”) onto the eye-bolt. Insert the eye-bolt through the 7
mm drilled hole and secure with a washer (item “H”) and nylon lock nut (item “I”).
9. Using the spring-loaded snap hooks, attach the restraining device to the bracket and the eye-bolt.

Be sure all controls are turned off prior to disconnecting. After reconnecting, be sure all controls are turned off and all
pilots are lit.
NOTICE
Adequate means must be provided to limit the movement of the appliance without depending on the connector
and the quick-disconnect device or its associated piping to limit the appliance movement.
The restraining means should be attached to a frame member on the back of the range.

STEP 3: ATTACH FLUE RISER AND SHELF ASSEMBLY
Place the flue riser assembly on the range as shown on the appropriate diagram below.
1. Slide the flue riser assembly over the bayonets until it bottoms out, as shown below.
2. Secure ends of flue riser assembly with two (2) 1/4-20 x 3/4 hex head bolts, flat washers and lockwashers
3. Attach the shelf assembly to the flue riser assembly.

STEP 4: ELECTRICAL CONNECTION (FOR CONVECTION-OVEN MODELS ONLY)
Wiring diagrams are located on the rear of the range. Be sure that the input voltage and phase match the
requirements shown on the serial plate (see Figure 1 on page 3).
Ranges are factory-equipped either with a power cord or with one or two two-pole terminal blocks (one for each oven),
located behind cover plate(s) located on the rear of the range. To connect the supply wires, remove the appropriate
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 ranges are wired as above, using only two supply wires. The third wire is not used and must be properly
terminated.
All ranges are shipped wired as specified by factory order. Conversion between single-phase and three-phase can be
accomplished by referring to phase loading and line amperes chart on wiring diagram for wire size and ampere
requirements.
STEP 5: GAS CONNECTION
If this equipment 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.
The serial plate is located on the interior side of the kick panel below the oven. It indicates the type of gas the range is
equipped to burn. All Southbend equipment is adjusted at the factory. Check type of gas on serial plate.
OWNER’S MANUAL 1182499 PAGE 17 OF 40

INSTALLATION MODEL 400-CE RESTAURANT RANGES
These models are design-certified for operation on natural or propane gases. For natural gas, the regulator is set to
deliver gas at 0.99 kPa (4" W.C.) pressure to the manifold. For propane gas, it is set to 2.48 kPa (10" W.C.).
This appliance should be connected ONLY to the type of gas for which it is equipped.
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.
The gas supply line to the range should be no smaller than the inside diameter of the pipes to which it is connected.
Purge the supply line to clean out dust, dirt, or other foreign matter before connecting the line to the range.
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 RANGE HAS BEEN PUT INTO
OPERATION. TEST PRESSURE SHOULD NOT EXCEED 3.47 kPa (14" W.C.).
STEP 6: CHECK THE INSTALLATION
Check the installation of the range, as follows:
1. Check that all screws and bolts are tightened.
2. Check that the electrical and gas connections have been made correctly.
3. With the range in the position that it will be operated, check that the range is level. If not, adjust the legs or
casters.
4. Check that the appropriate minimum clearances are satisfied (see page 4).
5. Check that the oven door(s) open and close properly.
6. Check that there is sufficient clearance in front of the range to open the oven door.
7. Wipe clean all surfaces.
STEP 7: CHECK OPERATION
Check the operation of the range, as follows:
1. Turn on the gas supply and, for convection-oven models, the electric power supply.
2. Light the burner pilots and oven pilot(s), starting with the top burner farthest from the gas input in order to
purge the system of air. Check for proper pilot-flame height and adjust pilots, if necessary.
3. Turn on the oven and all burners at the same time. Check for correct burner operation and adjust the air
shutters, if necessary.
4. On convection-oven models, turn on the blower(s) and check for proper operation.
5. Turn off the burners and oven.
STEP 8: SHUT-DOWN AND WIPE-CLEAN RANGE
Complete the installation by leaving the range ready for customer use:
1. Allow the range to cool.
2. Wipe clean all surfaces.
3. Unless the range is to be placed in service immediately, turn off the gas supply and (for convection-oven
models, the electricity supply.
4. Make sure that a copy of this manual will be available to the people who will operate and maintain the range.
