with the consumer for local inspector’s use
and for future reference.
Installation of any gas-fired equipment
should be made by a licensed plumber. A
manual gas shut-off valve must be installed
in the gas supply line ahead of the cooktop
in the gas stream for safety and ease of
service.
In Canada: Installation must be in
accordance with the current CAN/CGA
B149.1 & 2 Gas Installation codes and/or
local codes. Electrical installation must be in
accordance with the current CSA C22.1
Canadian Electrical Codes Part 1 and/or

FIRE/EXPLOSION
HAZARD
IF THE INFORMATION IN
THIS MAN AL IS NOT
FOLLOWED EXACTLY, A FIRE OR
EXPLOSION MAY RES LT CA SING
PROPERTY DAMAGE, PERSONAL
INJ RY, OR DEATH.
•DO NOT store or use gasoline or other
flammable vapors and liquids in the
vicinity of this or any other appliance.
• WHAT TO DO IF YOU SMELL GAS:
–DO NOT try to light any appliance.
–DO NOT touch any electrical switch.
–DO NOT use any phone in your
building.
–Immediately call your gas supplier
from a neighbor’s phone.
–Follow the gas supplier’s instructions.

DANGER
CHEMICAL HAZARD
If not installed, operated and
maintained in accordance
with the manufacturer’s
instructions, this product could expose
you to substances in fuel or from fuel
combustion which can cause death or
serious illness and which are known to
cause cancer, birth defects, or other
reproductive harm.
For example, benzene is a chemical
which is part of the gas supplied to the
cooking product. It is consumed in the
flame during combustion. However
exposure to a small amount of benzene
is possible if a gas leak occurs.
Formaldehyde and soot are byproducts
of incomplete combustion. Properly
adjusted burners with a bluish rather
than yellow flame will minimize
incomplete combustion.
WARNING
ELECTRICAL GROUNDING
INSTRUCTIONS
The cooktop must be electrically grounded
in accordance with local codes or, in the
absence of codes, with the ANSI/NFPA
No. 70-latest edition. Installation should
be made by a licensed electrician. This
appliance is equipped with a three-prong
grounding plug for your protection against
shock hazard and should be plugged
directly into a properly grounded
receptacle. DO NOT cut or remove the
grounding prong from the plug.
For personal safety, this appliance
must e properly grounded. DO NOT
under any circumstances cut or
remove the third (ground) prong from
the power plug.
WARNING
BURN HAZARD
The use of cabinets for storage above the
appliance may result in a potential burn
hazard. Combustible items may ignite,
metallic items may become hot and
cause burns. If a cabinet storage is to be
provided the risk can be reduced by
installing a range hood that projects
horizontally a minimum of 5” (12.7 cm)
beyond the bottom of the cabinets.
CAUTION
Before placing the cooktop into operation,
always check for gas leaks with a soapy
water solution or other acceptable method.
DO NOT SE AN OPEN FLAME TO
CHECK FOR LEAKS.
CAUTION
This appliance shall not be used for
space heating. This information is based
on safety considerations.

Electrical & Gas Requirements
Electrical Requirements
There is no connection necessary beyond
plugging the unit into a polarized
grounded 120 volt 60 Hz 15 amp circuit. A
minimum of 120VAC is required for proper
operation of gas ignition systems. DO NOT
use a GFI circuit. This circuit however MUST
be grounded and properly polarized. The
unit is equipped with 16-3 SPT2 power cord.
Note: If electrical power is not supplied or is
interrupted, the open top burners will have
to be lit manually with a match.
Gas Connection
The gas supply (service) line must be the
same size or greater than the inlet line of the
appliance. All cooktops use a 1/2” (1.3 cm)
I.D. NPT (Sch40) inlet. Sealant on all pipe
joints must be resistive to LP/Propane gas.
These cooktops are designed specifically for
natural gas or liquid propane (LP) gas. It is
shipped from the factory adjusted for use
with natural or propane (LP) gas. Before
beginning installation verify that the model is
compatible with the intended gas supply.
IMPORTANT: Any conversion required
must be performed by a qualified licensed
plumber or gas service company. The
proper conversion kit must be ordered
from your authorized service agency or
dealer.
Manual shut-off valve:
• The installer-supplied valve must be
installed in the gas service line ahead of
the appliance and regulator in the gas
stream and in a position where it can be
reached quickly in the event of an
emergency.
In Massachusetts: A “T” handle type
manual gas valve must be installed in
gas supply line to the appliance.
Pressure regulator:
• All heavy-duty commercial-type cooking
equipment must have a pressure regulator
on the incoming service line for safe and
efficient operation since service pressure
may fluctuate with local demand. The
regulator supplied with the cooktops must
be installed before any gas connections
are made.
Note: DGCU—The regulator for the ceramic
glass gas cooktop is installed in the unit.
• Manifold pressure should be checked with
a manometer; natural gas requires 5.0”
WCP and LP/Propane requires 10.0” WCP.
Incoming line pressure upstream for the
regulator must be 1” WCP higher than the
manifold pressure in order to check the
regulator. The regulator used on this
cooktop can withstand a maximum input
pressure of 1/2 PSI (14.0” WCP). If
the line pressure is in excess of that
amount, a stepdown regulator will be
required.
• The appliance must be disconnected from
the gas supply piping system during any
pressure testing of that system.

Clearance Dimensions (Wood/Composite Overlay)
The bottom of a standard hood should be
30” (76.2 cm) min. to 36” (91.4 cm) max.
above the countertop. This would typically
result in the bottom of the hood being
66” (167.6 cm) to 72” (182.9 cm) above the
floor. Refer to the rangehood installation
instructions for additional information. These
dimensions provide for safe and efficient
operation of the hood.

BURN HAZARD
The use of cabinets for storage above the
appliance may result in a potential burn
hazard. Combustible items may ignite,
metallic items may become hot and
cause burns. If a cabinet storage is to be
provided the risk can be reduced by
installing a range hood that projects
horizontally a minimum of 5” (12.7 cm)
beyond the bottom of the cabinets.
CAUTION
This appliance shall not be used for
space heating. This information is based
on safety considerations.
WARNING
Rigid Connections:
• Incoming gas is brought from an intake
pipe (not supplied) at the rear of the unit
to the pressure regulator; then to the
manifold pipe for distribution. The only
connection necessary is from the service
supply through the shut-off valve (not
supplied) to this intake pipe (not
supplied) to the regulator supplied but
not connected through the cooktop.
In Massachusetts: This appliance must be
installed with a 36” (3-foot) long flexible gas
connector.
LP/Propane Conversion
The VGSU and DGSU models are field
convertible to LP/Propane gas or natural
gas. The orifice spuds and regulator must be
physically changed. For the VGSU models
order conversion kit NK2VGSU to convert to
natural and LPK3VGSU to convert to
LP/Propane. For the DGSU models order
conversion kit DLPK to convert to
LP/Propane. Gas conversions should be
completed by a qualified technician. Refer to
instructions in conversion kit for gas
conversions.
The DGCU models are not field
convertible. The unit must be ordered
from the factory either natural or
LP/Propane.

grease etc. remaining from the
manufacturing process. Some stainless
steel parts may have a plastic protective
wrapper which must be peeled off. The
cooktop should be washed thoroughly
with hot soapy water and then rinsed and
wiped dry to remove these film residues
and any installation dust or debris before
being used for food preparation.
• All stainless steel body parts should be
wiped regularly with hot soapy water
and with a liquid cleanser designed for
this material if build-up occurs. DO NOT
USE steel wool abrasive cloths cleansers
or powders. If it is necessary to scrape
stainless steel to remove encrusted
material soak with hot wet cloths to
loosen the material then use a wood
or nylon scraper. DO NOT USE a metal
knife spatula or any other metal tool
to scrape stainless steel. Scratches are
almost impossible to remove.
