This service manual covers Models
DCS - (RD) - (36) (48) - (4) (6) - (GD) (GL) (GG)
DCS - (RD)-304
The DCS Professional Series of Dual Fuel
Ranges was designed to provide features tailored to a
customer with high expectations. This Service Guide
was created with the goal of minimizing customer
inconvenience and having any necessary repairs done
quickly and correctly. If, in the course of using this
manual, you should have any difficulty, or you feel
that some important item has been omitted, please let
us know with a phone call or Fax.
This manual was created for use by a qualified
technician, authorized by the DCS Service
Department.
To identify the Model and Serial #, locate and
read the appliance rating plate. The rating plate is
located on the rear left side of the interior top burner
box (remove the top burner grates and bowls), or on
the right side of the burner box on some six burner
models. In general, our Model numbering logic is as
follows;
1 2 3 4
ie. DCS-RD-484GG
1) (RD) denotes a Range with electric oven(s)
(27”& 24” self-cleaning) and an integral gas
cooktop.
2) (48)[47 7/8] , (36)[35 7/8] and (30)[29 7/8]
indicates unit nominal Width (in inches)
3) (4), or (6) indicates # of open top burners
4) (GG) indicates a Griddle and Char-Rock
Grill, (GD) indicates a thermostatically con
trolled Griddle section, or (GL) indicates a
Char-Rock Grill section.
Before servicing the range, it is first important to
accurately define the exact details of the com
plaint and then assess the cause of the defect.
Complete Installation Instructions are included
with each appliance and should be consulted to check
for proper installation practices. Charges related to
Installation are not covered under warranty. Common
for a product this large and heavy is damage due to reck-
less handling by trucking firms, or Installation personnel
moving the product into position.
What follows is an overview of DCS warranty
provision. Review the warranty policy to determine what
is covered under the warranty repair provisions and what
will not be covered. Before beginning any work, the pro-
posed service should either be authorized by DCS, or, in
the event the work is not covered under warranty, the
customer be informed of their responsibility for the
repair charges.

STEP ONE: ISOLATING THE PROBLEM
NOTE: Before addressing any specific prob-
lem the unit may have, it is advisable to help isolate
the nature of the problem by running a general check
of the 1) Gas Supply and 2) Electrical Supply. The
following procedure will narrow the possibilities and
help direct you to the source of the problem. A
detailed Troubleshooting section with specific symp-
toms and likely corrective courses of action follows
each sub-assembly Partlist section. Wiring diagrams
and schematics are also included to assist in trou-
bleshooting.
CHECK GAS SUPPLY
First, check to see if the gas has been turned on.
Next, gain access to the regulator by removing
the grates over the cooktop burners on the far left
hand side of the cooktop. Beneath the grates, towards
the rear of the burner box, the regulator is located
between the manifold and rear incoming gas line.
Check the top of the regulator to see that it is set up
for the type of gas supplied to the unit. The cap on
top of the regulator indicates whether the unit is set
up for NATURAL or L.P. gas.
When the gas supply is on, check the gas
pressure with a manometer. The front main open top
burner orifice is the most convenient place to check
gas pressure. To access the main burner orifice,
remove the four (4) screws that hold the burner hang-
er down and A) move aside the burner assembly or B)
disconnect the igniter wires and remove the entire
burner / hanger assembly. Hook up a flexible line to
the main burner orifice, turn that burner on... the
pressure should read 5.0" W.C. for Natural Gas, and
10.0" W.C. for L.P. Gas. Turn on other burners and
check for an excessive drop in pressure. A large drop
in pressure indicates a gas supply problem related to
installation, not covered by service warranty.
CHECK ELECTRICAL SUPPLY
First, check to see if the electricity has been
turned on.
Next, check power to the cord in the back of
the range and at the wall receptacle. If power is OK
there, the next area to check will be at the service dis-
connect located behind the valve panel. The Valve
Panel can be removed by removing the five (5) screws
that hold it in place. Two (2) screws are located at
each end of the panel, while one (1) screw (painted
Red) behind a Burner Control knob must also be
removed before the valve panel can be removed.
Once the Valve Panel has been removed, unplug and
check for power to the female side of the plug. 220-
240V 120 between red /white 120 between black /
white 240 between red & black
Check for power at the Terminal Blocks,
(Black & Red = Live, White = Neutral)

WHAT TO DO: USEFUL NOTES:
Customer smells gas at
all times
Customer smells gas
only when Open Top
Burners, Large Oven,
or Grill are in opera-
tion
Open Top Burner
Doesn't Light
CHECK for LEAKS at:
A) The two brass elbows coming from the
1/2"NPT pipe between the regulator and manifold
B) Along the manifold at every nut/washer
point and plug
C) At all connection points between tubing
and thermal valves at grill and griddle locations.
CHECK for LEAKS at:
A) The Thermal Valve and connections sup-
plying the Grill, with Grill turned on.
B) O-Ring between the Simmer Block and
Simmer Valve for all Open Top Burners, with burn-
ers on.
Is the igniter sparking? The spark should be
jumping to the simmer burner cap.
A) Make sure that the lead to the electrode is
secure, as well as the lead to the Spark Module and
that there is power also.
B) Spark Switches at control knobs should be
checked for power to and coming out from (with
knob in "lite" position. If there is power going to, yet
not coming out the other side, replace spark switch.
C) See Open Top Burner Lighting and
"Adjustable Low Setting" sections in the Installation
Manual.
NOTE: If using a
soap and water solution
when checking for
leaks, be careful not to
get any water on Spark
Switches, as doing so
will cause a short in the
switch.
NOTE: It is important
that correct # wire be
traced from the Spark
Switch,to the Spark
Module, to the Burner
Electrode.

GRIDDLE TROUBLESHOOTING
WHAT TO DO: USEFUL NOTES:
CHECK 1) the Electrical / Gas Supply as out-
lined in the General Instruction section.
2) Remove Griddle plate assembly (fas-
tened by 2 screws in the front and 1 screw in
the back, under the flue cover- Visually check
for igniter breakage. If igniter is broken,
remove / replace
3) Remove Valve Panel (see General
instructions and note removal of "Red" screw
behind control knob - not on all units)
4) 120 V supplied to Thermostat from
the terminal block ?(live= black) If not, trou-
bleshoot power supply lines, If YES,
5) Disconnect power, Remove wires off
Thermostat & check for continuity between
Thermostat terminals when Thermostat dial is
rotated to the ON. If there is no continuity
remove / replace Thermostat.
6) If Thermostat is OK, Remove the
wires from the Thermal Valve and check for
continuity between the two (2) terminals on
the face of the valve. If none, remove / replace.
7) If the Thermal Valve is OK, Remove
the wires from the Griddle Igniter and check
the igniter leads for continuity. If none, remove
/ replace igniter.
8) If the Igniter is OK, Check the
Neutral Return Wire for continuity to the neu-
tral (white) wire of the power supply cord.
1) Verify Gas supply to the unit. Turn
the Gas supply OFF. Loosen tubing supplying
gas from the manifold to the Thermal Valve at
the Thermal Valve. Quickly turn manual valve
On, then Off while an assistant listens closely
for the sound of flowing gas at the loosened
end of the connection. If gas is not flowing,
check the tubing for blockage.

PROBLEM AREA:
Griddle will not
operate
Griddle still will not
operate, (Electrically
operational - Steps 1-8
OK)
NOTE: Be careful not
to damage the
Capillary when remov-
ing the Griddle plate
assembly
NOTE: -Ensure at the
supply source that the
live and neutral wires
are not reversed ( If
they are, this would not
be covered under war-
ranty)

GRIDDLE TROUBLESHOOTING
WHAT TO DO: USEFUL NOTES:
If dirt or other foreign matter is blocking gas
flow, then the supply line should be discon-
nected and the line purged. This procedure is
not covered under warranty.
2) If gas is present at the Manual Valve,
and Electrical continuity of the valve exists per
Step 6)- (previous section), remove and visually
check the valve orifice for blockage. If none
exists, remove / replace Thermal Valve
CHECK 1) Gas pressure and supply as outlined in
the "General" section.
2) Ensure the orifice hood is not tightened
down onto the L.P. jet nested within the Thermal
Valve.
3) Adjust the air shutter closed until the
flame is yellow, then open slightly until the yellow
disappears.
1) To calibrate the Griddle Thermostat, place
a reliable griddle thermometer on the center of the
griddle plate. Rotate the thermostat to 350ºF. After 3
burner cycles, the griddle plate should have reached
equilibrium.
2) (You'll need a knob with a hole drilled
through the center to allow a flat-tipped screwdriver to
be inserted through it.) With the knob in place, insert
a thin blade, flat-tipped screwdriver through the
knob and nest it into the small slotted screw in the
thermostat (it may be necessary to clear the screw of
a small amount of sealant)
3) Note the temperature shown on the grid-
dle thermometer, then, while holding the screw still
with the screwdriver, rotate the knob to the ther-
mometer temperature. DO NOT TURN THE
CALIBRATION SCREW. Reset the temperature
and check for accuracy. Repeat if necessary.

NOTE: Before cali-
brating the Thermostat,
ensure that the griddle
sensing bulb is placed
within the small "V"
tube welded directly to
the bottom of the grid-
dle plate, pushed about
halfway back. The larg-
er piece of angle iron is
for flame diffusion, not
for placement of the
sensing bulb.
