CAUTION
— The cooktop, as shipped
from the factory, is set for use with its intended
gas. If you wish to use your cooktop with the
alternate gas, you must first replace the
orifices and convert the pressure regulator.
WARNING
— This conversion must
be performed by a qualified installer or gas
supplier in accordance with the manufacturer's
instructions and all codes and requirements of
the authority having jurisdiction. Failure to
follow instructions could result in serious injury
or property damage. The qualified agency
performing this work assumes responsibility
for the conversion.
CAUTION
— The following adjustments
must be made before turning on the burner.
Failure to do so could result in serious injury.
Be sure pressure regulator has been converted
as described in Step 1.

INSTALLATION INSTRUCTIONS
1 ADJUST THE REGULATOR
A. Disconnect all electrical power, at the main circuit
breaker or fuse box.

• Turn the spring retainer over so that the desired
gas is showing on the bottom.
• Snap the retainer back into position.
• Screw the cap back onto the regulator.
2 CHANGE BURNER ORIFICES
INSTALLATION TIP: First remove all orifices and then
start replacing them. This will help to prevent the
possibility that some may not be replaced.
A. Remove the burner grates, burner caps and burner
heads.
B. Using a 7mm nut driver, remove the top burner
orifices. There are two orifices per burner.
The main orifice is located low in the center of the
burner, while the simmer orifice is located higher
beside the center of the burner.
IMPORTANT: Orifices must be located exactly as shown.
Carefully read and observe each orifice label for correct
location.
C. Install the proper orifices in the exact locations as
noted in the illustrations at right.
D. Return the gas orifices to the bracket and reattach
the bracket and the instruction sheet to the pressure
regulator using the screw removed previously.
E. Replace the burner heads, caps and top grates.
3 ADJUST BURNER FLAMES
A. Turn all burners on highest setting and check the
flames. They should be blue in color and may have
some yellow tipping at the ends of the flame when
using LP gas. They should be blue (no yellow tipping)
when using natural gas. Foreign particles in the gas
line may cause an orange flame at first, but this will
soon disappear.
B. Turn the cooktop burner knob to "LO" while
observing the flame.
Adjust the setting of the upper row of flames using
the valve bypass screw as follows:
Adjustments must be made with two other burners in
operation on a medium setting. This prevents the upper
row of flames from being set too low, resulting in the
flame being extinguished when other burners are
turned on.
C. To adjust the flame, remove the knobs. Insert a small
flat blade screwdriver (3/32" [2–2.4mm] tip) through
the access hole in valve shaft as shown at right.
• If the flames were too small or fluttered, open the
valve more than the original setting.
• If the flames blew away from the burner, close the
valve more than the original setting.
D. Make the adjustment by slowly turning the screw
until flame appearance is correct.
E. Testing Flame Stability:
Test 1 – Turn the knob from "HI" to "LO" quickly.
If the upper row of flames goes out at this
setting, increase the flame size and test again.
Test 2 – With the burner on "LO", open and close the
cabinet door under the cooktop. If the flame
is extinguished by the air currents created
by the door movement, increase the flame
height and test again.
NOTE: When the burner is on the "SIM" setting, the
upper row of flames will go out, while the lower flame
remains on.
F. Flame Recheck:
After the adjustment is made, turn all burners off.
Ignite each burner individually. Observe the flame at
the "HI" position. Rotate the knob to the lowest setting
and be sure that the flame size decreases as the knob
is rotated counterclockwise.
Once the conversion is complete and checked ok,
fill out the conversion sticker and include your
name, organization and date conversion was made.
Apply the sticker near the cooktop gas inlet opening
to alert others in the future that this appliance has
been converted. If converting back to the original
gas, please remove the sticker so others know the
appliance is set to use its original gas.
