WAR NI NG
TO REDUCE THE RISK OF A COOKTOP GREASE FIRE:
Never leave surface units unattended at high settings. Boilovers cause
smoking and greasy spillovers that may ignite. Heat oils slowly on low or
medium setting. Always turn the Downdraft “ON” when cooking at high heat
or when cooking flaming foods. Clean ventilating fans frequently. Grease
should not be allowed to accumulate on fan or filter. Use proper pan size.
Always use cookware appropriate for the size of the surface element.
WAR NING
TO REDUCE THE RISK OF INJURY TO PERSONS IN THE EVENT OF A COOKTOP
GREASE FIRE, OBSERVE THE FOLLOWING: SMOTHER FLAMES with a closefitting lid, cookie sheet, or metal tray,then turn off the burner. BE CAREFUL TO
PREVENT BURNS. If the flames do not go out immediately EVACUATE AND
CALL THE FIRE DEPARTMENT. NEVER PICK UP A FLAMING PAN - You may be
burned. DO NOT USE WATER, including wet dishcloths or towels - a violent
steam explosion will result. Use an extinguisher ONLY if:
1.You know you have a Class ABC extinguisher, and you already know how to
operate it.
2.The fire is small and contained in the area where it started.
3.The fire department is being called.
4.You can fight the fire with your back to an exit.

SAFETY PRACTICES & PRECAUTIONS
WAR NING:
ALL WALL AND FLOOR OPENINGS WHERE THE Downdraft IS INSTALLED MUST
BE SEALED.
Consult the cooktop installation instructions given by the manufacturer before making any cutouts.
MOBILE HOME INSTALLATION - The installation of this Downdraft must conform to the Manufactured
Home Construction and Safety Standards, Title 24 CFR, Part 3280 (formerly Federal Standard for
Mobile Home Construction and Safety,Title 24, HUD,Part 280). Four wire power supply must be used
and the appliance wiring must be revised. See Electrical Requirements (page 4).
Venting system MUST terminate outside the home.
DO NOT terminate the ductwork in an attic or other enclosed space.
DO NOT use 4" laundry-type wall caps.
Flexible-type ductwork is not recommended.
DO NOT obstruct the flow of combustion and ventilation air.
Failure to follow venting requirements may result in a fire.
Electrical ground is required on this downdraft ventilation system.
If cold water pipe is interrupted by plastic, non-metallic gaskets or other materials, DO NOT use

DO NOT ground to a gas pipe.
DO NOT have a fuse in the neutral or grounding circuit. A fuse in the neutral or grounding
circuit could result in electrical shock.
Check with a qualified electrician if you are in doubt as to whether the downdraft is properly
grounded.
Failure to follow electrical requirements may result in a fire.
WAR NING:
TO REDUCE THE RISK OF FIRE, ELECTRICAL SHOCK,OR INJURY TO PERSONS,
OBSERVE THE FOLLOWING:
Use this unit only in the manner intended by the manufacturer. If you have
any questions, contact the manufacturer. Before servicing or cleaning unit,
switch power off at service panel and lock the service disconnecting means
to prevent power from being switched on accidentally. When the service
disconnecting means cannot be locked,securely fasten a prominent warning
device, such as a tag, to the service panel. Installation Work And Electrical
Wiring Must Be Done By Qualified Person(s) In Accordance With All
Applicable Codes And Standards, Including Fire-Rated Construction.
Sufficient air is needed for proper combustion and exhausting of gases from
fuel burning equipment through the flue (chimney) to prevent backdrafting.
Follow the heating equipment manufacturer's guideline and safety
standards such as those published by the National Fire Protection
Association (NFPA), and the American Society for Heating, Refrigeration and
Air Conditioning Engineers (ASHRAE), and the local code authorities. When
cutting or drilling into wall or ceiling, do not damage electrical wiring and
other hidden utilities. Ducted fans must always be vented to the outdoors.

PLANNING THE INSTALLATION
VENTING REQUIREMENTS
Determine which venting method is best for your application. Ductwork can extend either through
the wall or the roof. The length of the ductwork and the number of elbows should be kept to a minimum to provide efficient performance. The size of the ductwork should be uniform. Do not install
two elbows together. Use duct tape to seal all joints in the ductwork system. Use caulking to seal exterior wall or floor opening around the cap. Flexible ductwork is not recommended. If it is used, each
foot of flexible ductwork used is equivalent to two feet of straight metal ductwork when calculating
the duct run length. Thus, a flexible elbow equals two standard elbows. Make sure there is proper
clearance within the wall or floor for exhaust duct before making cutouts. Do not cut a joist or stud
unless absolutely necessary. If a joist or stud must be cut, then a supporting frame must be
constructed.
WAR NING:
To Reduce The Risk Of Fire,Use Only Metal Ductwork.
ELECTRICAL REQUIREMENTS
A 120 volt, 60 Hz AC-only electrical supply is required on a separate 15 amp circuit,fused on both
sides of the line. A time-delay fuse or circuit breaker is recommended. The fuse must be sized per
local codes in accordance with the electrical rating of this unit as specified on the serial/rating plate
located inside the unit near the field wiring compartment.
THIS UNIT MUST BE CONNECTED WITH COPPER WIRE ONLY. Wire sizes must conform to the requirements of the National Electrical Code,ANSI/NFPA 70 -latest edition,and all local codes and ordinances.
Wire size and connections must conform with the rating of the appliance. Copies of the standard listed
above can be obtained from:
National Fire Protection Association
Battery March Park
Quincy,Massachusetts 02269
This appliance should be connected directly to the fuse disconnect (or circuit breaker) through
flexible, armored or non-metallic sheathed copper cable. Allow some slack in the cable so the
appliance can be moved if servicing is ever necessary. A UL Listed, 1/2" conduit connector must be
provided at each end of the power supply cable (at the appliance and at the junction box). When
making the electrical connection, cut a 1-1/4" hole in the wall. A hole cut through wood must be
sanded until smooth. A hole through metal must have a grommet.
NOTE: SUITABLE FOR USE WITH SOLID STATE SPEED CONTROLS.
CAUTION:
For General Ventilating Use Only. Do Not Use To Exhaust Hazardous or
Explosive Materials and Vapors.

PLAN THE DUCTWORK
The DCS 36” and 30” downdraft vent system can be
ducted in four different directions; down, left, right or
back using a 3-1/4" X 10" rectangular vent. Fig. 03
illustrates venting options. Fig. 02 shows the ductwork
cutout dimensions.
CALCULATE THE DUCT RUN LENGTH
The ductwork length should not exceed 35 equivalent
feet for 3-1/4" X 10" duct, or 60 equivalent feet for 9"
round duct. Calculate the length of the ductwork by
adding the equivalent feet listed in Fig. 04 for each piece
of duct in the complete system. An example is given in Fig. 05. For best results, use no more than
three 90° elbows. Make sure that there is a minimum of 24" of straight duct between elbows if more
than one is used. Do not install two elbows together. Round duct is recommended instead of
rectangular duct especially if elbows are needed. Rectangular duct should transition to round as soon
as possible (6” round minimum).

PLAN AND MAKE THE CUTOUT
It is recommended that the installer draw the cooktop and downdraft cutouts on the countertop
before making any cutouts to avoid mistakes. Fig. 06 shows the cutout dimensions for DCS CT-365
and CT-304 and for all other cooktops see Fig. 06a (page 8). Fig. 07 shows the tolerances between the
cooktop and the downdraft. These tolerances must be observed for proper installation.
WAR NING:
When planning the cutout for the downdraft:
Draw both the cooktop and downdraft cutouts on the countertop before
making any cuts.
Check that there is enough room in the cabinet for both. Failure to follow
these warnings could result in damage to the countertop.

The lower support legs have
holes for mounting to the
cabinet floor and can be
installed on both sides
depending upon the length
required. Determine if the
holes should be in the front or
on the sides.
3) Carefully insert the unit into
the cutout. Due to the size and
weight, two people are
recommended when lifting
this unit. Make sure that the
downdraft is fully seated in the
cutout and the support arms
rest firmly on the countertop.
4) Adjust the lower support legs
until both rest firmly on the
cabinet floor. Place a level
vertically on the front side of
the blower box to make sure
that the unit is level and not leaning to
the front or rear. Once the unit is properly
aligned,mark a starter hole on the cabinet
floor where the lower support legs will
attach to the cabinet floor.
5) Remove the unit from the cabinet. Drill
starter holes in the cabinet floor for the
leg screws.
6) DCS downdrafts are shipped from the
factory ready to vent in the down
position. If you need to vent back, left or
right, then the blower must be repositioned.
To vent to the left or the right:
