INSTALLATION

INSTALLATION HEAVY DUTY COUNTERLINE

2.Install eye-bolt (item “F”) to a frame member on the rear of the appliance. After checking carefully behind the frame member for adequate clearance, drill a 1/4" hole through the frame member.

3.Thread hex nut (item “G”) and slide the washer (item “H”) onto the eye-bolt. Insert the eye-bolt through the 1/4" drilled hole and secure with a washer (item “H”) and nylon lock nut (item “I”).

4.Using the spring-loaded snap hooks, attach the restraining device to the bracket and the eye-bolt.

5.Using the cable clamp (item “D”), adjust the restraining device extended length to prevent over-bending or kinking of the appliance connector.

Note: For units not equipped with flame safety devices, be sure all valves are turned off prior to disconnecting. After reconnecting, be sure all valves are turned off and all pilots are lit.

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 appliance 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 appliance 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 appliance 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 appliance.

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 APPLIANCE 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 appliance is shut off.

2.Check that the manual shut-off valve inside the front panel door of the appliance is closed (60" and 72" models have two shut-off valves).

3.Check that all control knobs on the appliance are turned “OFF.”

4.Attach the pressure regulator shipped with the appliance to the 3/4" NPT gas inlet connector located on the rear of the appliance (see Figure 13 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.
