UNIVERSAL ORIFICE—OVEN APPLICATION

Gas cooking systems for both L.P. gas and natural gas can be used without changing orifices by using a univer- sal orifice.

The universal orifice consists of an L.P. gas insert that is threaded into a cap orifice. This insert is actually an orifice itself. When natural gas is used, the cap is in the

position shown in Figure 3-7. Gas enters through both the cap and the insert. The amount of gas leaving the orifice is controlled by the size of the cap orifice.

When L.P. gas is used, the cap is tightened down 2-1/2 turns so that it rests against the L.P. insert,

closing off the spacing between the two (see Figure 3-8). The amount of gas leaving the orifice is now controlled by the size of the L.P. insert.
