1.9.1Changing the Main Gas Orifice

1.The venturi tubes and manifold valves are on the same side as the spit handles.

2.On each venturi, loosen the lock nuts (7/8" wrench) and then move the nut and the air intake cap all the way to the top of the nipple.

3.With a 3/4" wrench, loosen the nipple so that it can be removed from the venturi.

4.With the nipple/orifice assembly off, separate the main orifice from the nipple with a pipe wrench or a pair of pliers.

Re-assemble all of the components with the new main orifice. Make sure that the proper air intake adjustment is made for the new type of gas (according to the tables on page 9). The flames should be blue in color, must be stable, and must not "lift off" the burner.
