ADJUSTING
BURNER FLAMES
1. Turn all burners full on and check the
flames. They should be blue in color with
some yellow tipping at the ends of the
flame. Foreign particles in the gas line
may cause an orange flame at first, but
this will soon disappear.
NOTE: For the 18,000 BTU/HR burner
(on some models) the cooktop burner
knob should be turned to the setting
before the lowest setting. This will
ensure that the entire burner is
operating.
2. Turn the cooktop burner knob to the
lowest setting while observing the
flame.
Adjust the low flame setting using the
valve bypass screw as follows:
Low-setting adjustments must be made
with two other burners in operation on
a medium setting. This prevents the low
flame from being set too low, resulting in
the flame being extinguished when other
burners are turned on.
3. To adjust the
flame, remove
the knobs. Insert
a screwdriver
through the
access hole in
valve switch.
Engage
adjustment
screw in valve.

a. If the flames were too small or
fluttered, open the valve more than
the original setting.
b. If the flames blew away from the
burner, close the valve more than the
original setting.
4. Make the adjustment by slowly turning
the screw until flame appearance is
correct.
Note: Some models may contain a
silicone shield which covers the valve
switch and access hole. A flashlight may
be required to locate the access hole. To
access the valve adjusting screw, push
the screwdriver through this shield. After
adjustment, reseat the shield around
the switch hub with your fingers, after
withdrawing the screwdriver.

5. Testing flame stability:
Test 1 – Turn the knob from “HI” to the
lowest setting quickly. If the flame goes
out at the lowest setting, increase the
flame size and test again.
Test 2 – With the burner on the lowest
setting, 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.
6. Flame recheck:
After the adjustment is made, turn all
burners off. Ignite each burner individually.
Observe the flame at the “HI” position.
Rotate the valve to the lowest setting and
be sure that the flame size decreases as
the valve is rotated counterclockwise.
TO CONVERT THE COOKTOP BACK TO
NATURAL GAS, REVERSE THE STEPS
UNDER MAKING THE L.P. CONVERSION.
Once the conversion is complete and
checked ok, fill out the LP 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 to LP. If converting back to
natural gas from LP, please remove
the sticker so others know the
appliance is set to use natural gas.
The L.P. orifice spuds for the cooktop burners
are attached to the regulator along with
separate LP conversion instructions.
CAUTION: The counter unit, as
shipped from the factory, is set for
use with natural gas. If you wish
to use your unit with Liquefied
Petroleum (Propane) 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.

To adjust your cooktop for use with L.P. gas,
follow these instructions:
1. Disconnect all electrical power, at the main
circuit breaker or fuse box.
2. Shut off the gas supply to the cooktop by
closing the manual shut-off valve.
3. Adjust the Pressure Regulator:
a. Unscrew the cap.
b. Carefully look at the spring retainer to
locate the NAT or LP position.
c.
Turn the spring retainer over by
rotating it 90 deg., pull it from the
cap, turn the spring retainer over so
that LP is showing, insert it back into
the cap, and then rotate it 90 deg.
into position.
d.
Screw the cap back onto the
regulator and tighten.

4. Change the cooktop burner orifices:
a. Remove the top grates, burner caps and
burner head.
b. Remove the spark igniter from the burner
base (if required to access orifices). Use a
No. 15 torx head driver bit to remove the
screws holding the burner base in position.
c. Using a 7mm nut driver, remove the top
burner orifices. These may be accessed
through the hole in the maintop.

The orifices have a spring loaded retaining
ring around the hex head to hold the orifice
in the nut driver during installation and
removal. A slight amount of force is required
to push the nut driver down over the ring.
NOTE: For orifices that do not have a spring-
loaded retaining ring, use pliers to hold
the orifice in position during initial thread
engagement or final removal to avoid
dropping the orifice in the cooktop. Then use
the nut driver to tighten or loosen.
IMPORTANT: Save the orifices removed from
the appliance for future use.

5.
Locate the LP orifices attached to
the regulator along with separate LP
conversion instructions. They will have a
digit for size and a letter for type of gas,
on the top or side. (Important: Save the
orifices removed from the appliance
for future use.)
