* If a countertop backsplash is used, it must be constructed
of non-combustible materials (such as masonry, ceramic,
granite, stainless steel, etc.) whenever the cutout to rear
vertical surface is less than 3-3/8".
IMPORTANT: Always maintain 2-3/4" Min. clearance from
cutout to front edge of countertop.
•Refer to “Installation Preparation” for
information on appropriate placement
and necessary clearances when planning
installation.
•Avoid placing cabinetry directly above
cooktop when possible.
–Clearance between cooktop and protected
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.
Advance
planning
•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.
–Working areas adjacent to the cooktop
should have 18" minimum clearance
between countertop and cabinet bottom.
•Use the Monogram gas stainless steel cook-
top with any 36" or wider exhaust hood with
350 CFM or greater air flow rating.
•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.

Cabinet Base
Recommended
Measure carefully when cutting countertop.
Make sure sides of opening are parallel and
rear and front cuts are exactly perpendicular
to sides.
•The Monogram stainless steel gas cooktop is
designed to fit in a 42" or larger base
cabinet. If the cooktop is installed into a 36"
cabinet base, modifications may be required.
A 36" cabinet base must allow for installation
of hold-down clips at the sides. The side
walls may need to be cut away to provide
this space.
•The cooktop chassis occupies 5-1/2" 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.
•In some cases, two 3/8" I.D. 45° elbows and a
pipe nipple may be added between regulator
and cooktop to move regulator further back
in order to avoid interference with drawer.
NOTE: Some countertops made from solid surface materials,
such as Corian® may require special cutout preparation (such
as radius corners and aluminum foil tape). Always consult the
countertop manufacturer for specific instructions.
•The countertop cutout for cooktop must be:
–35-5/16" min. to 35-7/16" max. wide
–18-7/8" min. to 19" max. deep
–Allow at least 3-3/8" clearance between
back of cutout and vertical combustible

locations
These cooktops are shipped from the factory
set for either natural gas or LP gas. Check to
be sure you have the correct cooktop for the
type of gas being used.
16"
7"
•The pressure regulator must be connected
in series with the manifold of the cooktop
and must remain in series with the supply
line regardless of type of gas being used.
•The natural gas model is designed to
operate at 5" water column pressure.
A regulator is required at the natural gas
source to provide a maximum of 7" water
pressure to the cooktop regulator.
8"
• The liquid propane model is designed to
operate at 10" water column pressure.
A regulator is required at the LP source
to provide a maximum of 14" water pressure
to the cooktop regulator.
42"
NOTE: Locate gas and electrical
supply within shaded area. Locations
shown for a 42" cabinet base, adjust
when using other cabinet size.
•A properly-grounded 3-prong receptacle
should be located within reach of cooktop’s
four foot power cord.
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.
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 mini-
mize the possibility of electric shock hazard
from this appliance.
•The customer should have the wall recep-
tacle 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 responsibil-
ity and obligation of the customer to have it
replaced with a properly grounded three-
prong wall receptacle.
•Make gas connection through rear wall, or
on cabinet floor at rear, as illustrated.
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.
Optional Combination Installations
This cooktop may be installed in combina-
tion with a ZVB36 Monogram Downdraft
Vent, a ZET1038 Single Oven or a ZTD910
Warming Drawer.
• The gas and electrical supply must be
located where it will not interfere with
vent housing, the oven or the warming
drawer. See pages 9 through 11 for
alternate installation requirements.
Do Not, Under Any Circumstances, Cut Or
Remove The Third (ground) Prong From The
Power Cord.
Do not use an extension cord.
IMPORTANT: Improper grounding and
improper polarity of the house wiring can
cause continuous sparking of the ignition
system. Be sure to check for correct
grounding and polarity.

– Appropriate flare nuts and adapters are
required at each end of the flexible

•Turn on the gas. Check for leaks using a
liquid leak detector at all joints in the system
(the pressure test fitting is on the side of the
regulator).
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.
CAUTION
Do not use a flame to check for
gas leaks.
