be purchased from Southbend (see page 29 for conversion instructions).
This appliance should be connected ONLY to the type of gas for which it is configured.
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 the manifold pressure.

An adequate gas supply line to the unit should be no smaller than the inside diameter of the pipe from the
unit to which it is connected.

Purge the supply line to clean out dust, dirt, or other foreign matter before connecting the line to the unit.
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 unit has been put into operation. Test pressure should not exceed 14" W.C.
