10. Natural Gas Conversion
Convert the Pressure Regulator for use with
Natural Gas (see figure 11)
A. Remove the cap from the pressure regulator.
B. Remove the plunger.
C. Turn the plunger upside down with the
enlarge end UP.
D. Replace the plunger inside the regulator. The
letters NAT or 4" W.C. should be visible on
the exposed end of the plunger.
E. Replace the cap on the pressure regulator.
F. Turn the valve hoods approximately 2 1/2
turns counterclockwise. This will move the
hood away from the mixer pin.
G. Apply gas, adjust pilots and burner air shutter
for proper flame.
H. There should be 4" WC pressure in the
manifold after conversion for proper operation
on Natural Gas.
11. Adjustments
Oven/Broiler Flame Adjustment
The air shutter adjustment is located on the venturi tube,
which sets on the hood of the valve, and is locked in
place with a Phillips head screw. If the air shutter needs
adjusting, loosen the screw and rotate the shutter to
allow more or less air to the burner tube (see figure 14).

Figure 14
For Natural Gas, the air shutter should be approximately
half open. For LP Gas, the air shutter nearly full open.
Too much air will cause the flame to lift awya from the
burner, Too little air will cause the flame to turn yellow
at the outer edges and soot to form,
Remember, the oven will be shipped from the factory set
for Natural Gas, unless otherwise stated. If connecting
to LP gas, be sure to follow procedure under
"Conversion" to change the regulator and burner orifice
to the LP setting.
