NOTICE
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).
A 3/4” NPT line is provided at the rear for the 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 inside the front lower 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.
This appliance should be connected ONLY to the type of gas for which it is equipped. The inlet pressure before the
regulator should be 7-10” W.C. for natural gas or 11-14” W.C. for LP gas.
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 I.D. 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.
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 UNIT HAS BEEN PUT INTO OPERATION.
TEST PRESSURE SHOULD NOT EXCEED 1/4” W.C.
1. Check that all screws and bolts are tightened.
2. Move the oven into the position at which it will be operated.
3. Check that the oven is level. If not, adjust the legs.
4. Check that the appropriate clearances are satisfied (see page 4).
