The correct operating manifold pressure for natural gas
is 3.5 w.c.i. The operating manifold pressure for propane
gas is 11 w.c.i. The gas valve pressure regulator can be
adjusted between 3 and 4 w.c.i. natural gas or 6 and 11
w.c.i.for propane.
The gas pressure coming out of the regulator and going
to the burner ring has been factory set. You should not
readjust the burner ring gas pressure. If you replace your
