•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.
–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.
–Working areas adjacent to the cooktop

•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.
Optional Combination Installations.
This cooktop may be installed in combination
with a ZVB36 Monogram Downdraft Vent, with
a ZTD910 Warming Drawer or with a ZET837

•Remove packaging from the cooktop.
•Position the cooktop over the opening,
making sure that the power cord is dropped

•Lower the cooktop into the cutout, pressing
gently and evenly to seat.
•Thumbscrew brackets are located on the
right and left sides of the cooktop.
•Turn thumbscrews to touch the underside of

•Install a manual shut-off valve in the gas line
in an easily accessible location.
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
to the pressure regulator, if local codes
permit.
– Appropriate flare nuts and adapters are
required at each end of the flexible
