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.

Southbend reserves the right to change specications 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.

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).

VENTILATION

WARNING

Improper ventilation can result in personal injury or death. Ventilation which fails to properly remove ue products can

cause headaches, drowsiness, nausea, or could result in death.

All units must be installed in such a manner that the ow of combustion and ventilation air is not obstructed. Provisions for adequate air supply must be provided. Do not obstruct the front of the unit at the bottom where the air lter is

located or below the oven door as combustion air enters at these locations.

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.

If a ventilation canopy is used, it is recommended that the canopy extend 152.4 mm (6”), past the appliance and that the bottom edge be located 1981 mm (6’6”) from the oor. 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 lter.

A strong exhaust fan tends to create a vacuum in the room and may interfere with burner performance or may extinguish pilot ames. Fresh air openings approximately equal to the fan area will relieve such a vacuum. The exhaust fan should

be installed at least 609.6 mm (24”), above the vent opening at the top of the unit.

NOTICE

Due to the variety of problems encountered by outside weather conditions, venting by canopies or wall fans is preferred over any type of direct venting.

If the unit is connected directly to an outside ue, a CSA design certied down draft diverter must be installed.

In case of unsatisfactory performance on any 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.

FREE STANDING BROILERS

ELECTRICAL SUPPLY

Free-standing models (170, 171, and 270) units are wired standard 120V (60Hz single-phase AC). 120V models have

a 7-foot (2134 mm) power cord with a grouded plug. Optional units wired for 208/240V power and have a junction-box located behind the blower switch for connecting wires to a single-phase 208/240V source. Blower motor requires 1 amp.

An electrical diagram is located behind the air-intake lter on free-standing models (see Figure 1).

An electrical diagram for oven base broilers is located on the rear of the oven.

The appliance, when installed, must be electrically grounded in accordance with local codes, or in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70, or the Canadian Electrical Code, CSA C22.2, as applicable. An electrical diagram is located on the rear of the oven, near the motor.

GAS SUPPLY

Southbend cooking equipment is design-certied for operation on natural or propane gases. Southbend cooking equipment is shipped congured and adjusted for the type of gas specied by the purchaser, which is indicated on the serial plate (see Figure 1. Connect the Southbend cooking equipment ONLY to the type of gas for which it is congured

and adjusted.

Free-standing broilers (170, 171, and 270) have a 3/4” NPT rear male gas connection.

The broiler sections are design-certied for operation on natural or propane gases. For natural gas, the regulator is set to

9.963 mbar (4” W.C.). For propane gas, it is set to 24.909 mbar (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 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.

If using a exible-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. An adequate means of restraint to prevent undue strain on the gas connection must be provided as outlined in the installation section of this manual.

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” NPT pressure tap is located on the manifold to measure the manifold

pressure (See Figure 3). The supply line to the unit should be no smaller than the inside diameter of the pipe on the unit to which it is connected.

To ensure optimum unit operation the pressure in the main supply line, when all units are operating simultaneously, should not drop below 17.436 mbar (7” W.C.) for natural gas and 27.4 mbar (11” W.C.) for propane gas.

STEP 5: CONNECT ELECTRICITY (OVEN BASE)

A wiring diagram is located behind on the rear of the oven. Be sure that the input voltage and phase match the requirements shown on the serial plate.

Oven-bases ordered with a 115V, 60Hz, single-phase electrical rating are factory-supplied with a three-wire cord with

a three-prong plug that ts any standard three-prong grounded receptacle. Each standard oven requires a 15 ampere

supply, while each convection oven requires a 20 ampere supply.

Oven-bases 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 tting 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 used and must be properly terminated.

All units are shipped wired as specied by factory order. Conversion between single-phase 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 6: CONNECT ELECTRICITY (BROILER)

Wiring diagram location will vary depending on the model:

- For broilers with an oven base the wiring diagram is located on the rear of the oven base.

- For free standing broilers the wiring diagram is located behind the lter (See Figure 1)

Be sure that the input voltage and phase match the requirements shown on the serial plate.

Broilers ordered with a 115V, 60Hz, single-phase electrical rating are factory-supplied with a three-wire cord with a three-

prong plug that ts any standard three-prong grounded receptacle. Each standard oven requires a 15 ampere supply.

Broilers ordered with a 208/240V, 60Hz, single phase electircal rating are factory supplied with a three wire cord. A plug,

(not provided) must be installed.

An optional electic element rated at 3000 watts, 208/240V, is available in the wiring oven. ** This is indicated on the serial plate by the prex EW. A seperate electric supply, 208/240V, single phase, 20 AMP must be connected to the leads in a terminal box at the rear, near the top of the broiler. This installation must conrm with local codes, or in their absence, with the NATIONAL ELECTRICAL CODE ANSI/NFPA 70-Latest Edition. Canadian installation must comply with CSA C22.1

Canadian Electrical Code Parts I and II.

STEP 7: CONNECT GAS SUPPLY

If the Southbend equipment is being installed at over 2,000 feet altitude and that information was not specied when

ordered, contact the appropriate authorized Southbend Service Representative or the Southbend Service Department.

Failure to install with proper orice sizing will result in poor performance and may void the warranty.

Southbend equipment is design-certied for operation on natural or propane gases. The units are shipped congured and adjusted for the type of gas specied by the purchaser, which is indicated on the serial plate (see Figure 1). Connect the equipment ONLY to the type of gas for which it is congured and adjusted.
