Gas Valve
The ideal incoming gas pressure is 11 w.c.i. (water col-
umn inches) minimum 6 w.c.i., maximum 14 w.c.i. or 1/
2 psig. The correct operating manifold pressure for natu-
ral gas is 3.5 w.c.i. The operating manifold pressure for
propane gas is 11 w.c.i. The gas valve pressure regula-
tor 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 gas valve, you will need to adjust the new valve.
Refer to your machine’s
specification plate
for the
correct pressure setting. Follow the installation and ad-
justment instructions provided with your replacement
valve.

function or break down, grounding provides a path of
least resistance for electric current to reduce the risk of
electric shock. The product must be connected to an
appropriate power source that is properly installed and
grounded in accordance with all local codes and ordi-
nances.
