Southbend cooking equipment is design-certified for operation on natural or propane gases. Southbend cooking
equipment is shipped configured and adjusted for the type of gas specified by the purchaser, which is indicated on the
serial plate (see Figure 1 and Figure 2). Connect the Southbend cooking equipment ONLY to the type of gas for which it is
configured and adjusted.
Oven base broiler has a 1-1/4” front gas manifold that can be coupled to adjacent section(s). Sections can be ordered
with an optional 1” rear gas connection with a male NPT connector. Minimum supply pressure is 17.436 mbar (7” W.C.) for
natural gas, 27.4 mbar (11” W.C.) for propane. An external pressure regulator and shut off valve must be provided. If using
a flexible-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. Provide an adequate means of restraint to prevent undue strain on the gas connection.
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.
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 supply line to the sectional unit should be no smaller than the inside diameter of the pipe on the equipment 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.

Broilers with convection-oven bases with optional electronic ignition require electric power (50Hz or 60Hz single-phase
AC). 120V models have a 7-foot (2134 mm) power cord with a grounded plug (1.0 amps for “D” Models and 4.8 amps for
“A” Models). The 208/240V models have a terminal block for connection to a single-phase 208/240V source (1.0 amps for
“D” Models and 2.6 amps for the “A” Models).
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.
