2.Remove access cap by using a screw-
driver or quarter, turning the access cap
counterclockwise.
The gas pressure
regulator has two
settings which are
stamped on either side
of the cap.Turn the cap
and reinstall into
regulator with the stamp
“LP” visible from the
outside of the regulator.
The regulator must be checked at a minimum
1-inch (2.5 cm) water column above the set
pressure.The inlet pressure to the regulator
should be as follows for operation and
checking the regulator setting:
L.P. GAS:
Minimum pressure 10 inches (25.4 cm) W.C.
Supply pressure 14 inches (35.5 cm) W.C.
Testing below 1/2 psi (3.5 kPa) 14 inches
(35.6 cm) W.C. (gauge) or lower.
The cooktop must be isolated from the gas
supply piping system by closing its individual
manual shutoff valve during any pressure
testing of the gas supply piping system at test
pressures equal to or greater than 1/2 psig
(3.5 kPa).
3.Remove burner cap.
4.All burners use a
12,000 BTU, blue, size
110 L.P. orifice.

water column.
Examples of a qualified person
include licensed heating
personnel, authorized gas
company personnel, and
authorized service personnel.
Failure to do so can result in
death, explosion, or fire.

Part No. 4455110
8.Leak testing of the appliance shall
be conducted according to the following
instructions:
Use a brush and liquid detergent to test
all gas connections for leaks.Bubbles
around connections will indicate a leak. If
a leak appears, shut off gas valve
controls and adjust connections.Then
check connections again. NEVER TEST
FOR GAS LEAKS WITH A MATCH OR
OTHER FLAME. Clean all detergent
solution from cooktop.
Electronic Ignition System —
initial lighting
Cooktop burners use electronic ignitors in
place of standing pilots.When the
cooktop control knob is pushed in and
turned to the “LITE” position, the system
creates a spark to light the burner.This
sparking continues until the control knob
is turned to the desired setting.
9.Check operation of the cooktop
burners. Push in and turn each control
knob to “LITE” position. The flame should
light within 4 seconds. Do Not leave the
knob in the “LITE” position after
burner lights.
If burners do not light properly, turn
control knob to the “OFF” position. Check
that burner cap is in the proper position.
Check that power supply cord is plugged
in and that circuit breaker or house fuse
has not blown. Check that the shutoff
valve is in the “ON” position. Check
operation again. If a burner does not light
at this point, contact your KitchenAid
dealer for assistance.
11.Check flame on “HI”for a blue
color.It should be clean and soft in character.No yellow tip, blowing or lifting of
flame should occur.Occasional orange
flashes are normal and reflect different
elements in the air or gas.
12.Completely fill out conversion
label (part no. 4455047) and attach the
label to the bottom of the cooktop beside
the rating tag. Do not cover the rating tag
with the conversion label.
13.For higher altitudes, no further
adjustments are necessary.Derating the
burners is also unnecessary.
14.Save the orifices removed from
the unit along with these instructions for
possible future use.
NATURAL GAS:
To convert back to Natural gas: Follow
steps 3 through 11.
10.Push in and turn each control
knob to the “LO” (or simmer) position. The
“LO” setting of each burner has been
factory set to the lowest position available
to provide reliable reignition of the burner.
If it does not stay lit on the “LO”position,
check “LO” position as follows:
a.Turn control knob to “LITE” until burner
ignites.
b.Quickly turn control knob down to “LO”
position.
c. If burner goes out, readjust valve as
follows:
Remove the surface burner control knob.
Insert a flat-blade screwdriver into the
hollow valve stem and engage the slotted
screw. Flame size can be increased or
decreased by turning the screw. Adjust
flame until you can quickly turn control
knob from “HI” to “LO” position without
extinguishing the flame.Flame should be
as small as possible without going out.
