INSTALLATION--GAS CONNECTIONS
r_ PROVIDE ADEQUATE GAS SUPPLY
This cooktop is designed to operate on natural
gas at 5" of water column manifold pressure and
7" of water column (W.C.) supply pressure. It is
shipped from the factory set for natural gas. The
convertible pressure regulator supplied with the
unit must be connected in series with the manifold
of the cooktop and must remain in series with the
supply line regardless of whether natural or L.P.
gas is being used. FOR PROPEROPERATION, THE
MAXIMUM INLET PRESSURETO THE REGULATOR
MUST BE NO MORE THAN 14" OF WATER COLUMN
PRESSURE.For checking the regulator, the inlet
pressure must be at least 1" W.C.. (or 3.4 KPA)
greater than the regulator output setting. If
the regulator is set for 5" W.C. of water column
pressure, the inlet pressure must be at least 6" W.C.
If the regulator is set for 10" W.C., the inlet pressure
must be at least 11" W.C.. The gas supply line to
the cooktop should be 1/2" or 3/4" pipe.

COOKTOP BURNERS
E_ ASSEMBLING THE COOKTOP BURNERS
The electrode of the igniter is exposed. Be careful not to turn on any cooktop controls
while the top of the burner is removed. Do not remove the top or touch the electrode
of any burner while another burner is turned on. Electrical shock might result.
[] Place the burner head onto the burner base. Make sure to place the correct
burner head on the correct burner base and that the burner head sits level on
the burner base. The burner heads are not interchangeable. Ensure the slot in
the burner head is positioned over the electrode and that the burner head is
fully inserted inside the burner base. A small gap between the base and head is
normal.
Place the burner caps on the burner heads, making sure to place the correct
[]
burner cap on the correct burner head. The burner caps are not
interchangeable. Each cap has three to four pins. Make sure that the burner
caps are properly seated on the burner heads and that none of the pins sit in the stability chamber.

[_ CHECK IGNITERS
Operation of the electric igniters should be checked after the cooktop and supply line have been carefully
checked for leaks and the cooktop has been connected to the electrical power.
On models so equipped, check to be sure the cooktop is in the UNLOCKED position.
rA1 Push and turn a burner valve to the LITE position. All spark igniters will make a series of sparks (ticking
sounds), but only the burner turned to LITE will light.
. The burner should light when gas is available to the burner.
. Once the burner lights, it should be turned out of the LITE position.
r_ Try each valve separately until all burners have been checked.

COOKTOP BURNERS (CONT.)
ITI BURNER IGNITION
Cooktop Spark Ignition-When you turn the
cooktop knob to LITE, the spark igniter makes a
series of electric sparks (ticking sounds) which light
the burner. During a power failure, the burners will
not light automatically. In an emergency, a cooktop
burner may be lit with a match by following the
steps below.
On models so equipped, check to be sure the
cooktop is in the UNLOCKED position.
EA1 Light a match and hold the flame near the
burner you want to light. Wooden matches
work best.
r_ Push in and turn the control knob slowly. Be
sure you are turning the correct knob for the
burner you are lighting.
NOTE: If the burner does not light within five seconds,
turn the knob off and wait one minute before trying
again.
[_] BURNER GRATES
The three cooktop grates are designed for specific
positions. For maximum stability, these grates
should only be used in their proper position with
the edges positioned on top of the black bumpers

MAKING THE LP CONVERSION
r_ SAFETY INFORMATION YOU
SHOULD KNOW
The pressure regulator and burner orifices are set

the regulator along with separate LP conversion
instructions.
At- ^, ,,T,,,,_ L,
,_I:L_.,,/RU/IU I_: The cooktop, as shipped from
the factory, is set for use with natural gas. If you
wish to use your cooktop with LPgas, you must
first replace the orifices and convert the pressure
regulator.
AIlI_W/"_I'II_i I i_1_: 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.
_IL_,,,/_U/|UI_I: The following adjustments
must be made before turning on the burner. Failure
to do so could result in serious injury. Be sure

ADJUST BURNER FLAMES
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.
r_ 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.
E1 To adjust the flame,
remove the knobs. Use
screwdriver to remove
valve stem plugs as
shown.
Insert a screwdriver
through the access hole
in valve switch. Engage
adjustment screw in
valve. Refer to the
illustration below that
matches the adjustment
screw location for
your model. The
griddle burner (PGP959
and CGP3501 has 2
adjustment screws,
one for the left rear
burner and one for the

griddle control. Griddle
control must be turned

r_ Testing Flame Stability:
Test 1 - Temporarily replace knobs. 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 -
El 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, REVERSETHE STEPSUNDER MAKING THE LP
CONVERSION.
Once the conversion is complete and checked ok,
replace valve stem plugs and knobs, and fill out
the LP sticker. 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 gas. If converting back to natural gas from
LP, please remove the sticker so others know the
appliance is set to use natural gas.
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.
, If the flames blew away from the burner,
close the valve more than the original
setting.
r_ Make the adjustment by slowly turning the
screw until flame appearance is correct.
