Installation
WARNING: Before beginning the installation,
switch power off at the service panel and lock the
service disconnecting means. When the service
disconnecting means cannot be locked, securely
fasten a warning tag to the service panel.
Before You Begin...
Note: The complete installation instructions
are inclosed with the
Use and Care Manual .
Carefully read and follow these instructions.
Gas Supply
WARNING: Cooktop model ZGU375NS isshipped
from the factory set to operate only with natural
gas. Do not use with LPG. If you wish to use
LPG, you must have cooktop model ZGU375LS.
These cooktops are designed to operate on natural
gas at 4 in. of water column pressure or on LP gas
at 10 in. of water column pressure, depending on
model. For proper operation, the maximum inlet
pressure to the regulator must be no more than
10 in. of water column pressure for natural gas
and 14 in. of water column pressure for LP gas.

Gas Supply Shutoff Valve
The cooktop itself is not equipped with a gas shut-
off valve. If installed correctly, a shutoff valve will be
in the main gas supply line “upstream”of the
appliance pressure regulator.
Measuring the Gas Pressure
Supplied to the Burners
A pressure tap hole is located on the side of the
regulator to allow checking of the manifold pres-
sure. Remove the regulator plug and install a
WB02X10820 tap (or 1/8 in. NPT nipple) for test
with a manometer. Turn on the gas and light at least
one burner to serve as a load. Reinstall the regular
plug and check for leaks.
Optional Combination Installations
This cooktop may be installed in combination with a
ZVB36 Monogram downdraft vent, with a ZTD30
warming drawer, or with a ZET837 single convec-
tion oven. The gas and electrical supply must be
located where it will not interfere with the vent
housing, the oven, or the warming drawer.

Cooktop Features and Controls
Throughout this manual, features and appearances may vary from the customer’s model.
Ignition System
The surface burners are lit by electronic ignition,
eliminating the need for standing pilot lights with
constantly burning flames.
The ignition system consists of 5 spark switches
(1 on each valve), 5 spark electrodes (1 on each
burner), and a spark module.
WARNING: All 5 electrodes will spark when any
burner control knob is turned on. Do NOT
touch any of the burners when the igniters
are clicking.
The burners relight automatically if the flame goes
out. The burner control knob can be turned to any
position from HIGH to LO to light the burner. The
sparking will quit after the burner has been lit.
The burners may spark if a draft blows the flame
away from the burner sensor.
The ignition system is not sensitive to reversed
house wiring polarity.
Lighting a Burner
Push the control knob down and turn it counter-
clockwise to the desired position from HIGH to
SIM.
In case of a power outage, you can light the burn-
ers with a match. Hold a lit match to the burner,
then push in and turn the control knob to the de-
sired position. Use extreme caution when light-
ing burners this way.
Surface burners in use when an electrical power
failure occurs will continue to operate normally.

Burner Cleaning
The slits in the burner rings of the cooktop must
be kept clean at all times for an even, unhampered
flame.
The electrode of
the spark igniter is
behind each burner.
When one burner is
turned to “ON”to
light, all the burners
spark. Do not attempt to disassemble or clean
around any burner while another burner is
on. An electric shock may result, which could
cause you to knock over hot cookware.
Electrode
Note: Before removing the burner caps and
burner ring subassemblies, remember their size
and location. Replace them in the same location
after cleaning for proper burner operation.

To completely clean the burner ring subassembly
remove the burner cap, head, and the 1-1/16 in.
nut. Lift off the burner ring. Do not remove the
burner bases.
Make sure the small holes in the simmer rings are
kept open. A sewing needle or wire twist-tie works
well to unclog them.
Ho es
S its
To remove burned-on food, soak the burner heads
Check to be sure the burner you turned on is
the one you want to use.
After the burner lights, turn the knob in
eitherdirection to adjust the flame size. To turn a
burner off, turn the knob clockwise as far as it will
go, to the OFF position.
The indicator lamp in the bezel for each knob
verifies the burner is ON.
Caution: Do not operate a burner for an extended
period of time without cookware on the grate. The
finish on the grate may chip without cookware to
absorb the heat.
Selecting Flame Size
All 5 burners on your cooktop have 2 rows of
flames. These dual-flame burners have an upper
ring of main burner ports which produce the main
flame for high-heat cooking from the HI knob
setting to the LO knob setting.
Main F ame
Simmer F ame
The bottom simmer flame is used for simmer
heat cooking operations such as melting choco-
late, holding food at serving temperature, and
simmering.
Both MAIN and SIMMER flames are lit when the
knob is between HI and LO. Only the simmer
flame is lit when the knob is in the SIMMER
position.

There is no adjustment on this burner. See

and rings in a solution of mild liquid detergent and
hot water for 20-30 minutes. For more stubborn
stains, use a toothbrush. Clean the burner
bases in place on the cooktop.
Before putting the burner parts back, shake out
excess water and then dry them thoroughly by
setting them in a warm oven for 30 minutes.
Replace the burner parts. Make sure that the rings,
heads, and caps are replaced in the correct
location. There are four medium sets and one
large set of rings, heads, and caps.
To replace the burner parts, make sure all parts
are for the correct burner, in the correct location,
and firmly seated.Align the locator pin on the
burner ring into the labeled hole in the burner base.
Replace the burner ring locking nut and hand-
tighten. Turn the nut 1/4 turn to secure it in place.
Align the locator pin in the burner head into the
hole in the burner ring. Replace the burner cap.

Cooktop Cleaning
If cooktop has discolored from high heat, advise
customer to use the furnished cleaner (WB64X93)
identified in Owner’s Manual.
Selecting Cookware
Aluminum: Medium-weightcookware is recom-
mended because it heats quickly and evenly. Most
foods brown evenly in an aluminum skillet. Use
saucepans with tight-fitting lids for cooking with
minimum amounts of water.
Cast Iron: If heated slowly, most skillets will give
satisfactory results.
Enamelware: Under some conditions, the enamel
of some cookware may melt. Follow cookware
manufacturer’s recommendations for cooking
methods.
Glass: There are two types of glass cookware:
those for oven use only and those for surface
cooking (saucepans, coffee pots, and teapots).
Glass conducts heat very slowly.
Heat-Proof Glass Ceramic: This can be used for
either surface or oven cooking. It conducts heat
very slowly and cools very slowly. Check the
cookware manufacturer’s directions to be sure it
can be used on gas cooktops.
Stainless Steel: This metal alone has poor
heating properties and is usually combined with
copper, aluminum, or other metals for improved
heat distribution. Combination metal skillets
generally work satisfactorily if they are used at
medium heat as the manufacturer recommends.
Using Woks
Use woks with the provided support ring on the
center burner only. Make sure that the support ring
is securely locked onto the center grate fingers.
Do not try to use round-bottomed woks without the
ring. You could be seriously burned if the wok tips
over.
The wok ring is designed to accommodate most
standard size woks from 12 in. to 18 in. Ensure
that the wok is properly nested in the ring prior to
cooking. The wok should be stable, and the bottom
of the wok should not touch the center grate when
in the wok ring.
