36" gas updraft cooktops
For those who prefer gas heat for
cooking, the Monogram built-in
gas updraft cooktop offers the
cooking method of choice.
These cooktops are only 3" deep
and can be installed over cabinet
drawers.
These models are shipped for natural gas operation.
They can be converted to liquid propane. (Order
JXLP56 conversion kit).

–Clearance between cooktop and protected
•Refer to “Installation Preparation” for
information on appropriate placement and
necessary clearances when planning installa-
tion.
•Avoid placing cabinetry directly above
cooktop when possible.
Advance
planning
cabinetry must not be less than 24".
–An exhaust hood that projects at least 5"
beyond front of cabinets can reduce risk of
burns caused by reaching over heated
surface units.
–Working areas adjacent to the cooktop
should have 18" minimum clearance
between countertop and cabinet bottom.
•Use the Monogram gas updraft cooktop with
any 36" or wider exhaust hood, if desired;
no special ventilation is required.
•Installation must conform with local codes.
In the absence of local codes, the gas cook-
top must comply with the National Fuel Gas
Code, ANSI Z223.1, latest edition.
•If cabinetry is used above cooking surface:
–Use cabinets no more than 13" deep.
–Maintain 30" minimum clearance between
cooktop and unprotected cabinets directly
above cooktop.
–If clearance is less than 30", protect cabinet
bottoms with flame-retardant millboard at
least 1/4" thick, or gysum board at least
3/16" thick, covered with 28 gauge sheet
steel or .02" thick copper.

to sides.
•The Monogram gas updraft cooktop is
designed to fit in a 36" or larger base cabinet.
•Cooktop requires 3" free space below
countertop.
•If installing cooktop above a cabinet with
drawers, it may be necessary to use a shorter
length drawer to allow clearance for gas
connection.
•The countertop cutout for cooktop must be: •In some cases, two 3/8" I.D. 45° elbows and
–34-1/2" wide
–18-1/8" deep
–Allow at least 4-5/8" clearance between
back of cutout and wall.
a pipe nipple may be added between regula-
tor and cooktop to move regulator further
back in order to avoid interference with
drawer.
–Allow at least 8-13/16" clearance from right
and left side of cutout to adjacent wall.
–Allow at least 2-1/4" clearance between
front of cutout and front edge of
countertop.

These cooktops are designed to operate on
natural gas at 4" of water column pressure or
on LP gas at 10" of water column pressure.
–These cooktops are shipped from the
factory set for natural gas. If you decide
to use this cooktop with LP gas, conversion
adjustments must be made by a service
technician or other qualified person.
JXLP56 conversion kit is required for
LP operation.

For proper operation, the maximum inlet
pressure to the regulator must be no more
than 10" water column pressure for natural
gas and 14" water column pressure for LP gas.
•When checking the regulator, the inlet
pressure must be at least 1" greater than the
regulator output setting.
–If the regulator is set for 4" of water column
pressure, the inlet pressure must be at
least 5".
Electrical supply:
This cooktop features pilotless electric
ignition for energy savings and reliability. It
operates on a 120 volt, 60 Hz power supply. A
separate circuit, protected by a 15 amp time
delay fuse or circuit breaker, is required.
•A properly-grounded 3-prong receptacle
should be located within reach of cooktop’s
four foot power cord.
IMPORTANT: (Please read carefully).
FOR PERSONAL SAFETY, THIS APPLIANCE
MUST BE PROPERLY GROUNDED.
The power cord of this appliance is equipped
with a three-prong (grounding) plug which
mates with a standard three-prong grounding
wall receptacle to minimize the possibility of
electric shock hazard from this appliance. The
customer should have the wall receptacle and
circuit checked by a qualified electrician to
make sure the receptacle is properly
grounded and has correct polarity.
Where a standard two-prong wall receptacle is
encountered, it is the personal responsibility
and obligation of the customer to have it
replaced with a properly grounded three-
prong wall receptacle.
–If the regulator is set for 10" of water
column pressure, the inlet pressure must
be at least 11".
For ease of installation, and if local codes
permit, the gas supply line into the cooktop
should be 1/2" or 3/4" ID flexible metal
appliance connector, three to five feet long.
Note: Purchase new flexible line. DO NOT
USE OLD, PREVIOUSLY USED FLEXIBLE
LINE.
•Make gas connection through rear wall, or
on cabinet floor at rear, as illustrated.
Do Not, Under Any Circumstances, Cut Or
Remove The Third (ground) Prong From The
Power Cord.
Do not use an extension cord.

Note: If the cooktop is installed into a 36"
base cabinet, the pressure regulator MUST BE
installed to the bottom of the cooktop before
the cooktop is placed into the cabinet.

Install
•Remove packaging from the cooktop.
•To insure a good fit, position the cooktop
over the cutout opening and carefully lower
into place. Check edges all the way around
to be sure all cutout edges are concealed
and there are no gaps.
Cooktop
•Carefully, lift and remove the cooktop.
1/16"
Note: If the cooktop is installed in a 36" base
cabinet, the mounting brackets cannot be
used because of interference with the cabinet
sides. In this case, the cooktop can be secured
to the cabinet with angle brackets (not
supplied).
–Remove one screw at the bottom of the
cooktop body on both sides and secure the
bracket with those screws. Then, secure the
brackets to the cabinet sides.
3/8"
•Insert hold-down bracket into highest slots
on the right and left sides of the cooktop:
–Cooktop has three slots, the highest
available will depend on the thickness of
the countertop.
•Cut a 3/16" gasket strip in half. Peel off the
backing and apply to the underside of the
glass cooktop edge.
–on each side at least 3/8" from the back
and as close to the edge as possible without
protruding.
•Apply the other gasket strip to the underside
of the glass at the front of the cooktop.
•Remove remaining adhesive backing.
•Position the cooktop over the opening,
making sure that the power cord is dropped
into the cabinet.
•Secure the brackets to the underside of the
countertop with screws provided.
•Lower the cooktop into the cutout, pressing
gently and evenly to seat.

Installation
Gas Updraft Cooktop
•Install the supplied pressure regulator and
nipple in the gas line as close to the cooktop
inlet as possible. Allowances for ventilation
ducting may be necessary.
–Make sure the regulator is installed in the
right direction.

•Install a manual shut-off valve in the gas line

Solid Piping
or Flexible
Connector
Note: Instead of using solid piping to connect
to pressure regulator, an approved flexible
metal appliance connector may be used
between the pipe stub and the shut-off valve
and the pressure regulator, if local codes
permit.
– Appropriate flare nuts and adapters are
required at each end of the flexible
connector.

IMPORTANT: Disconnect the cooktop and
the individual shut-off valve from the gas
supply piping system during any pressure
testing of that system at test pressures greater
than 1/2 psig. Isolate the cooktop from the
gas supply piping system by closing the
individual manual shut-off valve to the
cooktop during any pressure testing of the gas
supply piping system at test pressures equal to
or less than 1/2 psig.
•Turn on the gas. Check for leaks using a
liquid leak detector at all joints in the system
(the pressure test nipple is adjacent to the
gas inlet pipe on the rear right hand side of
the cooktop bottom.
CAUTION
Do not use a flame to check for
gas leaks.
