NOTICE

Installation must comply with 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.

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.

Southbend 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.

This product is intended for commercial use only, not for household use.

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 natural gas. A kit for conversion to using propane gas is included (see instructions in kit or page 9 of this manual).

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.

An adequate gas supply line to the unit should be no smaller than the inside diameter of the pipe from the unit to which it is connected.

Purge the supply line to clean out dust, dirt, or other foreign matter before connecting the line to the unit.

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 unit has been put into operation. Test pressure should not exceed 14" W.C.

! CAUTION

THIS 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 PSIG (3.45 kPa).

THIS 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 PSIG (3.45 kPa).

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.

All units 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 unit, as combustion air enters through this area. 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 hood 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.

MEDIUM DUTY COUNTERLINE INSTALLATION

INSTALLATION

NOTICE

Installation must comply with 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.

These installation procedures must be followed by qualified personnel or warranty will be void.

Step 1: Unpack

IMMEDIATELY INSPECT FOR SHIPPING DAMAGE

INSTALLATION

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.

1. Uncrate carefully. Report any hidden damage to the freight carrier IMMEDIATELY.

2. Do not remove any tags or labels until unit is installed and working properly.

Step 2: Covert Unit to Use Propane Gas (if necessary)

Each unit is shipped equipped with fixed orifice hoods appropriate for use with natural gas. If propane gas will be used, convert the unit for use with propane gas by the following procedure:

1. Remove the front panel by removing the knobs and screws on the front.

2. For charbroiler and open top models, remove the grates and burners to access the orifices from above. For griddle models, slide the burner toward the rear of the unit to access the orifices (see diagram on page 22), OR remove the griddle plate to access the orifices by removing two nuts at the rear of the unit.

3. Remove the natural gas orifices and install the furnished propane orifices.

4. Re-install the burners.

5. Re-install the front panel.

6. Remove the hex-threaded plug from the pressure regulator. Inside is a removable insert. Pull the insert out, turn it around, and put it back in so that the end with the letters “LP” is now facing you. Re-attach the hex-threaded plug. The pressure regulator is now set for 10" (25.4 cm) water column.

7. Check the pressure.
