WARNING: THESE PROCEDURES MUST BE FOLLOWED BY QUALIFIED PER-
SONNEL OR WARRANTY WILL BE VOIDED.
I
GENERAL:
The unit, when installed, must conform with local codes, or in the absence of local codes, with the
National Fuel Gas Code, ANSI Z223.1-Latest Edition.
The unit, when installed, must be electrically grounded and comply with local codes, or in the absence
of local codes, with the National Electrical Code ANSI/NFPA 'IO-Latest Edition.
Canadian installation must comply with CAN/CGA-B149.1 Natural Gas Installation Code, Code
CAN/CGA-B149.2 Propane Installation Code, and CSA C22.1 Canadian Electrical Code Parts I and II.
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, blower air shutters and pilot heights should be
checked at installation and adjusted if necessary. Check type of gas on serial plate on the left front
edge of the top.
For orifice sizes and pressure regulator settings refer to the chart under "SPECIFICATIONS."
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 2223.1-1988. 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 will restrict the volume of gas
required for satisfactory performance. A pressure regulator, which is provided with each unit, is set to
maintain a 4" W.C. manifold pressure for natural gas and lo" WC. manifold pressure for propane gas.
However, to maintain these conditions the pressure on the supply line, when all units are operating
simultaneously, should not drop below 7" WC. for natural gas or 11" W.C. for propane gas.
All pipe joints should be tested for leaks with a soap and water solution before operating the unit. The
;est 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 12 PSIG (3.45 kPa).
THIS APPLIANCE MUST BE ISOLATED FROM THE GAS SUPPLY PIPING
SYSTEM BY CLOSING ITS INDIVIDUAL M.&'WAL SHUTOFF VALVE DURING
ANY PRESSURE TESTING OF THE GAS SUPPLY PIPING SYSTEM AT TEST
PRESSURES EQUAL TO OR LESS THAN I I2 PSIG (3.45 kPa).
A l/8" pressure tap is located on each manifold of the "A" suffix units, just behind the panel above the
broiling section(s). On "D" suffix units the l/8" pressure tap is in the blower compartment, just after
the pressure regulator.
EXBAUST FANS AND CANOPIES:
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" or more with the horizontal. This prevents dripping grease and facilitates collecting the run-off
grease in a drip pan, usually installed with a filter. A strong exhaust fan tends to create 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 shelf or backsplash.
NOTE: Due to the variety of problems encountered by outside weather conditions, venting by
canopies or wall fans is preferred over any type of direct venting.
WARNING: All units must be installed in such a manner that the flow of combustion and
ventilation air are not obstructed. Provisions for an adequate air supply must also be provided.
Do not obstruct the front of the unit at the bottom where the filter is located, as combustion air
enters these areas.
