INSTALLATION
Step 4: Assembly of Fryer as Part of a Battery
If the fryer is to be assembled with other units as part of a battery, do the following:
1. Position the center range of the battery and carefully level that unit. Use a long spirit level four ways;
across front top rail and the rear collar plate, and along each edge.
2. Remove all front valve panels. Mark them so that they can be returned to their respective unit.
3. Bring up adjacent unit and level it using the same method and by using the center unit as reference.
Match front rails and rear collar plates. When a battery is set on a masonry base and legs are not used,
shims may be used. Special attention should be given to Fry Top ranges to allow proper drainage on
griddles.
4. Where spreader plates are installed, refer to Sectional Battery Component Assembly Instructions
supplied with each unit.
5. Connect and test the gas supply as described in Step 5, then re-install the valve panels.
Step 5: Gas Connection
The fryer has a 1-1/4" gas supply manifold located inside the top front edge and an optional 1" a rear gas
connection (see illustrations on pages 8, 35, and 37). Depending on the customer’s specification when the
unit was purchased, the ends of the gas supply manifold may both be open (for connection to adjacent units
on both sides), one may be open (for connection to one adjacent unit), or neither may be open (for a
freestanding fryer). The optional rear gas connection may be present for use by a freestanding fryer, or as a
supply connection for a battery.
The serial plate (located inside the front door of the fryer) indicates the type of gas the unit is equipped to
burn (natural gas or propane). The fryer should be connected ONLY to the type of gas for which it is
equipped.
All Southbend equipment is adjusted at the factory; however, pilot height should be checked at installation
and adjusted, if necessary (see page 24).
For orifice sizes and pressure regulator settings, see the chart on page 6. If the fryer 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.
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
necessary for satisfactory performance. A combination gas valve and pressure regulator, which is provided
with each unit, is set to maintain a 4" W.C. manifold pressure for natural gas or 10.0" W.C. 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" W.C. for natural gas or 11" W.C. for propane gas.
Fluctuations of more than 25% on natural gas or 10% on propane gas will create problems and affect burner
operating characteristics. A 1/8" tap to measure the manifold pressure is located on the burner manifold (see
illustrations on pages 35 and 37).
Purge the supply line to clean out dust, dirt, or other foreign matter before connecting the line to the unit.
It is recommended that an individual manual shutoff valve be installed in the gas supply line to the unit.
Use pipe joint compound that is suitable for use with both natural and LP gas on all threaded connections.
