INSTALLATION
WARNING: THESE PROCEDURES MUST BE FOLLOWED BY QUALIFIED PER-
SONNEL OR WARRANTY WILL BE VOIDED.
GENE-
The installation must conform with local codes, or in the absence of local codes,with the National
Fuel Gas Code, ANSI Z223.1-Latest Edition. In addition, units with the Convection Oven Base must
be electrically grounded and comply with local codes, or in the absence of local codes, with the
National Electrical Code ANSI/NFPA 70-Latest Edition. Canadian installation must comply with
CAN/CGA-B149.1 Natural Gas Installation Code, CodeCAN/CGA-B149.2 Propane Installation Code.
Canadian Electrical CodeParts I, or Local Codes and CSA C22.1.
These models are design certified for operation on Natural or Propane gases.
The appliance should be connected ONLY to the type of gas for which it is equipped. All Southbend
equipment is adjusted at the factory, however, burner air shutters and pilot heights should be
checked at installation and adjusted if necessary. Check type of gas on serial plate in the compart-
ment below the oven for Model 32-4OC,or in the bottom front of the cabinet on Model 32BC.
For orifice sizes and pressure regulator settings refer to the chart under “SPECIFICATIONS.”
Each range is a complete unit with an individual 1-l/4” NPT manifold across its entire width. Units
can be batteried by joining the unions at the ends of the manifolds. This manifold is not equipped
directly with a pressure regulator. However, the manifold must be connected with an adequately
sized gas appliance regulator adjusted to supply a pressure to this manifold as marked on the serial
plate; 6” W.C. for natural gas and 10” W.C. for propane gas. In addition, the pressure regulator must
meet the following requirements:
1. The pressure regulator installed should be certified by a recognized testing agency.
2. The regulator should be acceptable for total pilot load application.
3. The regulator must have a maximum regulation capacity for the total connected load.
4. The regulator must have a pressure adjustment range to allow adjustment to the manifold
pressure on the appliance rating plate.
5. Unless the manifold pressure of all connected appliances is the same, a separate regulator must
be supplied for each unit(s) to indicate unit or units having a differing manifold pressures.
6. 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-Latest Edition. Canadian installation must comply with CANKGA-
B149.1 Natural GAs Installation Code, Code CAN/CGA-B149.2 Propane Installation Code.
An adequate gas supply is imperative. Undersized or low pressure lines will restrict the volume of
gas required for satisfactory performance. A steady supply pressure, between 7” W.C. and 8” W.C. for
natural gas and 11” W.C. and 12” W.C. for propane gas, is recommended. With all units operating
simultaneously, the manifold pressure on all units should not show any appreciable drop.
Fluctuations of more than 25% on natural and 10% on propane gas will create pilot problems and
affect burner operating characteristics. Contact your gas company for correct supply line sizes.
As an option, the unit may be supplied with a rear gas connection. The pipe size of this connection is
one inch. Unless otherwise specified, this connection is welded to the right side of the manifold.
A l/8” pressure tap is located on the manifold of each unit.
All pipe joints should be tested for leaks with a soap and water solution before operating the unit.
The 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
OF1 I2 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 1I2 PSIG (3.45 kPa).
