INTRODUCTION
3
The DCS Professional CS Cooktops feature a large number of features varying with each model . All
models feature a minimum of 4 surface burners, with the option of up to 6 surface burners on all
models. All of the 48" and 36" Cooktops feature the possibility of various grill and griddle
combinations. All cooktop models require the installation of one of the two offered backguards, if
installed with less than 12” to combustible material. See page 10.
IMPORTANT INSTALLATION INFORMATION
The cooktops are tested in accordance with ANSI Z21.1 Standard for Household Cooking Gas
Appliances. These cooktops must be installed in conjunction with a suitable overhead vent hood. (See
Step 2 for ventilation requirements). Due to the professional high heat capacity of this unit, particular
attention should be paid to the hood and duct work installation to ensure it meets local building
codes. To eliminate risk of burns or fire by reaching over heated surface units, cabinet storage located
above the surface units should be avoided. Check local building codes for the proper method of
cooktop installation. Local codes vary. Installation, electrical connections, and grounding must comply
with all applicable codes. In the absence of local codes, the cooktop should be installed accordance
with the National Fuel Gas Code ANSI Z223.1-1988 and National Electrical Code ANSI / NFPA 70-1990.
Be sure that the unit being installed is set up for the kind of gas being used. The gas cooktop is shipped
from the factory set and adjusted for natural gas or LP (propane), depending on the specific model
ordered. Verify that the cooktop is compatible with gas supply at the installation site before
proceeding further. Return cooktop to dealer if unit is not set for site gas supply.

PLANNING THE INSTALLATION
5
RECOMMENDED INSTALLATION INSTRUCTION
(If installing a full backguard with the cooktop)
A) Vent Hood
B) Backguard System
C) Cooktop
1) Locate cooktop according to cooktop installation instructions.
2) Measure distance from counter surface to top of trim on cooktop adding 1/8” for backguard
clearance.
3) Transfer this measurement to the wall. This will mark the bottom of your backguard.
4) From this line measure 30 1/16” up wall to mark top of 30” backguard. This is the minimum height
that the bottom of your vent hood can be installed.
6) Follow vent hood manufacturer’s installation instructions to install vent hood.
7) Follow backguard installation instructions to install backguard.
8) Connect gas and electric connections and slide cooktop into position.

UNPACKING AND HANDLING
6
STEP 1:
MOVING AND PLACING THE COOKTOP
NOTE: If a solid side cabinet wall exists on one or both sides, you will need to notch the
front corner of the cabinet to match the counter top notch and to provide clearance
for the cooktop front (see page 8).
CAUTION:
Proper equipment and adequate manpower must be used in moving the
cooktop to avoid personal injury or damage to the unit
ANCHORING THE COOKTOP
The cooktops have a shipping weight of approximately 228 pounds (36" models) and 324 pounds (48"
models). After removal of packing materials, it is recommended that the grates and drip pan (below
knobs) be removed to facilitate handling. This will reduce the weight to about 150 pounds.
DO NOT REMOVE THE GRILL OR GRIDDLE ASSEMBLIES.
It may be necessary to remove the cooktop knobs to pass through some doorways. With the knobs
removed a 29-3/8" wide opening is required. Remove the outer carton and packing material from the
shipping base. The cooktop is held to the skid by four straps. After removing the straps, the cooktop
must be lifted and removed from the skid.
The professional cooktop should be moved close to its final location. Electric and gas connections
should be made (steps 5 & 6 pgs. 12 & 13) and the backguard installed (as required, step 4 pg. 11)
before the cooktop is placed in its final position. The grill and griddle sections are fastened in place at
the front with screws.They are designed to be stationary and not meant to be removed for cleaning.
The griddle has two leveling screws beneath the rear flue cover which can be used to adjust the
griddle to the desired slope.The center screw is for shipping and should be removed.
Due to the weight of the cooktop, along with a built-in side frame gasket that is meant to rest and
create a seal on the counter top once installed, it is not necessary to anchor the unit to the counter.

VENTILATION REQUIREMENTS
7
STEP 2:
A suitable exhaust hood must be installed above the cooktop. The following chart indicates the
minimum blower capacity recommended for hood ventilation.
* When installing a unit featuring a grill, select a blower on the high end of recommendation.
** For all 36” Cooktop GL models a 1200 CFM ventilation unit is required.
CAUTION:
Ventilation hoods and blowers are designed for use with single wall ducting.
However, some local building codes or inspectors may require double wall
ducting. Consult local building codes and/or local agencies, before starting, to
ensure that hood and duct installation will meet local requirements.
Hood blower speeds should be variable to reduce noise and loss of heated or air conditioned
household air when maximum ventilation is not required. Normally, the maximum blower speed is
only required when using the grill. For best smoke elimination, the lower edge of the hood should be
installed a minimum of 30" to a maximum of 36" above the cooktop cooking surface, (step 3 pg. 8). If
the hood contains any combustible materials (i.e.a wood covering) it must be a minimum of 36" above
the cooking surface. Due to a high volume of ventilation air, a source of outside replacement air is
recommended. This is particularly important for tightly sealed and insulated homes. A reputable
heating and ventilating contractor should be consulted.

STEP 3:
1) To ensure professional results, the cabinet and countertop openings should be prepared by a
qualified cabinet worker. We recommend having the cooktop available before cutting the opening
for more precise dimension verification.
2) The clearances shown in Fig. 5 pg. 10 are required for all types of backguard installations.
3) The cooktop is designed to hang from the countertop from its side flanges. The countertop,
however, must be strong enough to support this heavy cooktop. It may be necessary to add a
supporting cleat along each side or other form of support such as a 2”x 4”corner brace on each side,
or a deck to set the cooktop on. See Fig.1.
4) The cooktop can be installed in various positions with the front either flush or projecting,
depending on the countertop depth. See Fig. 2 & Fig. 4 (cooktop side view).
5) Establish the centerline of the desired cooktop location. It should be the same as the center of the
overhead ventilation hood.

HOOK-UP TO GAS SUPPLY
13
STEP 6:
HOOK-UP
A manual valve must be installed external to
the appliance, in an accessible location from
the front for the purpose of shutting off the
gas supply. Make sure the gas supply is turned
off at the wall valve before connecting the
appliance. The gas supply connections should
be made by a qualified technician and in
accordance with local codes or ordinances. In
the absence of a local code, the installation
must conform to the National Fuel Gas Code
ANSI 223.1-1988, latest edition.
To prepare the unit for connection to the gas
supply, thread the supplied 1/2” pipe nipple
into the elbow on the end of the manifold. The
elbow is located inside the chassis of the unit,
on the end of the manifold, facing down. See
fig. 9. It is accessible through the square cutout
in the left rear corner of the chassis bottom.
Connect the outlet of the regulator to the
exposed end of the nipple, connect the flex line
from the gas supply to the inlet side of the
regulator.
NOTE: The arrow on the regulator
indicating direction of gas flow
should be pointing towards the
unit. The flex line for the gas
supply must be metal and be
approved by an approved
certifying agency (AGA, CGA, or
UL.). Never use a hose made of
rubber or other synthetic material,
as the heat may cause the hose to
melt and develop leaks.
CAUTION:
The appliance must be isolated from the building’s gas supply piping system
by closing its individual manual shut-off valve during any pressure testing of
the gas supply piping system at test pressures equal to or less than 1/2 psig
(3.5kPa.).The appliance and its individual shut-off valve must be disconnected
from the gas supply piping system during any pressure testing of the system at
the test pressures in excess of 1/2 psig (3.5kPa.). When checking the manifold
gas pressure, the inlet pressure to the regulator should be at least 7.0” W.C. for
natural gas or 12.0” for LP.

TEST AND ADJUSTMENTS
14
STEP 7:
CAUTION:
For warranty coverage, DCS requires that burner adjustments be made by a
qualified technician at the time of installation. Extreme care should be used
when adjustments are made after installation. Improper or lack of
adjustments will void your warranty.
AIR SHUTTER ADJUSTMENT
(Griddle or Grill only)
Check for the proper burner flame character-
istics and adjust air shutters if necessary
(fig.10). Each air shutter is individually tested
and adjusted prior to shipment. Normally
adjustment is not required, however,
vibration during transit, or variations in the
local gas supply may make minor
adjustments necessary. Burner flames
should be blue and stable with no yellow
tips, excessive noise or lifting of the flame
from the burner. If any of these conditions
exist, check that the air shutter or burner
ports are not blocked. If this condition
persists, adjust the air shutter as required. If
the flame is too yellow, indicating insufficient
air, adjust the shutter counterclockwise to
increase air inlet. If the flame is noisy or tends
to lift away from the burner, indicating too much
air, turn the shutter clockwise to reduce air.
The griddle flames should be 1-1/2" to 2".
The grill burner flames should be 3/8” to 5/8” (fig. 10).
SURFACE BURNERS
The surface burners are not adjustable. Proper operation is achieved when the correct orifices for gas
supply are installed at the factory, based on model ordered.
If the surface burner does not ignite, check the spark igniter by listening for a clicking sound. If you
do not hear the igniter click, turn off the burner. Check for a tripped circuit breaker, blown fuse, or
poor wire connection to the igniter.
TO CLEAN EXTERIOR SURFACES
The stainless steel surfaces may be cleaned by wiping with a damp soapy cloth. Any mild glass cleaner
will remove fingerprints and smears. Do not use steel wool as it will scratch this surface. Small
scratches may be removed by lightly sanding with the grain using 120 grit paper.
