Step 4: Connect Gas Supply
The serial plate is located interior side of the control panel (see Figure 1 on page 3). It indicates the type of
gas the griddle is equipped to burn. All Southbend equipment is adjusted at the factory. Check type of gas
on serial plate. This appliance should be connected ONLY to the type of gas for which it is equipped.
If the griddle 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.
These models are design-certified for operation on natural or propane gases. For natural gas, the
convertible regulator shipped with the griddle is set to deliver a 4” W.C. pressure to the manifold. For
propane gas, it is set to deliver 10” W.C.
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. A 1/8” pressure tap is located on the
manifold to measure pressure.
Purge the supply line to clean out dust, dirt, or other foreign matter before connecting the line to the griddle.
Use pipe joint compound that is suitable for use with LP gas on all threaded connections.
! 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
GRIDDLE HAS BEEN PUT INTO OPERATION. TEST PRESSURE SHOULD NOT EXCEED 14”
W.C.
To connect the gas supply, do the following:
1. Check that the gas supply to the piping that will be connected to the griddle is shut off.
2. Check that the manual shut-off valve inside the front panel door of the griddle is closed (60" models have
two shut-off valves).
3. Check that all control knobs on the griddle are turned “OFF.”
4. Attach the pressure regulator shipped with the griddle to the 3/4" NPT gas inlet connector located on the
rear of the griddle (see Figure 11 below). Be sure that the regulator is connected so that the gas flow is
in the same direction as the arrow on the bottom of the regulator.
5. Connect the vent line from the pressure regulator 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.
6. Connect the gas inlet of the pressure regulator to the building’s supply system. No segment of the gas
supply connection to the griddle should be smaller than 3/4" NPT. Standard pipe fittings are required.
7. Turn on gas supply.
8. Check for leaks using soapy water.
