ELECTRICITY SUPPLY
Convection ovens require connection to a supply of electricity. The appliance, when serviced, 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 side of the control panel assembly in each unit. (see drawing on page 5).
Power Option Power Type # of Ovens Maximum Amps
120/60/1 120 Volts, 60 Hz, Single Phase
208/60/1or3 190-219 Volts, 60 Hz, Single or Three Phase
240/60/1or3 220-240 Volts, 60 Hz, Single or Three Phase
240/50/1or3 208-240 Volts, 50 Hz, Single or Three Phase
Ovens ordered with the 120V power option are equipped with one or two power cords with a standard
120V single-phase plug with a ground prong. Single-deck ovens will have one power cord; double-deck
ovens will have two.
Ovens with other power options have a terminal block on the rear of the oven that must be wired to the
power supply. Depending on how the power supply is connected to the terminal block, the oven can
operate on either single-phase of three-phase power.

INFORMATION
GAS SUPPLY
The serial plate is located inside the lower front panel. 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. For natural gas, the
regulator is set to deliver a 4.0" W.C. pressure to the manifold. For propane gas, it is set to deliver 11"
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/CGAB149.2, as applicable.
This appliance should be connected ONLY to the type of gas for which it is equipped.
A 3/4" NPT line is provided at the rear for the gas connection. 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.
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 1/4" W.C.
