INSTALLATION
WARNING:
THESE PROCEDURES MUST BE FOLLOWED BY QUALIFIED PERSONNEL
OR WARRANTY WILL BE VOIDED.
GENERAL:
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 70-1987. Canadian installation must
comply with CAN/CGA-B149.1 Natural Gas Installation Code, Code CAN/CGA-B 149.2 Propane Installation Code.
Canadian Electrical Code Parts I, or Local Codes and CSA C22.1
These models are 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. Check type of gas on serial plate in the compartment below the oven.
Each range is a complete unit with an individual 1-1/4" 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 pressure 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 nationally recognized testing agency.
2.
The regulator must have a maximum regulation capacity for the total connected load.
3.
The regulator must have a pressure adjustment range to allow adjustment to the manifold pressure on the appliance
rating plate.
4.
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 differing manifold pressures.
5.
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 Z233.1-1988. Canadian
installation must comply with CAN/CGA-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 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 proble ms 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 1/8" 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 OF 112 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 112 PSIG (3.45 KPA).
EXHAUST FANS AND CANOPIES:
Be sure to inspect and clean ventilation system according to the ventilation equipment manufacturers instructions. Canopies
are set over ranges, ovens, etc., for ventilation purposes. It is recommended that a canopy extend 6" past appliance and be
located 6'6" from the floor. Filters should be installed at an angle of 45 degrees or more with the horizontal. This prevents
dripping grease and facilities collecting the run-off grease in a drip pan, usually installed with a filter. A strong exhaust fan
tends to created a vacuum in the room and may interfere with burner performance or may extinguish pilot flames. Fresh air
openings approximately equal to the fan area will relieve such vacuum. In case of unsatisfactory performance on any
appliance, check with the exhaust fan in the "OFF" position.
WALL EXHAUST FAN:
Should be installed at least two feet above the vent opening at the top of the shelter backsplash.
