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.
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.
