Models  
Available  
These models are shipped for natural gas  
operation. They can be converted to liquid  
propane. (Order JXLP56 conversion kit.)  
These gas downdraft cooktops are equipped  
with an vent system which can be retracted  
when not in use.  
JXBA56WW, white or JXBA56BB, black  
motor and blower assembly is required for  
both models. Be sure to order the color that  
matches the cooktop.  
JXRB57 optional accessory for indoor  
remote location of the blower/motor  
assembly. Use this kit when the blower and  
motor assembly will be located outside of or  
below the cabinet floor.  
JXBC57 optional outdoor cover accessory  
may be ordered for installation of blower  
and motor assembly on the outside wall.

G as Downdraft Cooktop  
The combined installation of a downdraft vent Base Cabinet Requirements:  
Advance  
Planning  
and cooktop require careful consideration.  
This installation requires a 24" min. deep  
cabinet base. The cabinet must be at least 36"  
wide.  
Countertop Requirements:  
The countertop must have a deep flat surface  
to accommodate the cooktop and the vent.  
Countertops with a rolled front edge and  
backsplash may not provide the flat surface  
area required.  
Clearances  
least 1/4" thick or gypsum board at least  
3/16" thick covered with 28 gauge sheet  
steel or .02" thick copper.  
Clearance between cooktop and protected  
cabinetry must not be less than 24".  
The downdraft system with blower, motor  
and ductwork will occupy the cabinet below  
the cooktop. Drawers cannot be installed  
below this cooktop.  
Refer to “Dimensions & Clearances” for  
information on appropriate placement and  
necessary clearances when planning installa-  
tion.  
Avoid placing cabinetry directly above the  
cooktop when possible.  
If cabinetry is used above cooking surface:  
Use cabinets no more than 13" deep.  
Maintain 30" minimum clearance between  
cooktop and unprotected cabinets directly  
above cooktop.  
EXCEPTION: Installation of a listed micro-  
wave oven or cooking appliance over the  
cooktop shall conform to the installation  
instructions packed with that appliance.  
Working areas adjacent to the cooktop  
should have 18" minimum clearance be-  
tween countertop and cabinet bottom.  
Installation must conform with local codes.  
In the absence of local codes, the gas cooktop  
must comply with the National Fuel Gas Code,  
If clearance is less than 30", protect cabinet ANSI Z223.1, latest edition.  
bottoms with flame-retardant millboard at  
Ductwork Advance Planning  
Prepare ductwork to vent to outdoors:  
Use the shortest and straightest duct run  
possible:  
Duct run should not exceed equivalent  
length of 150 feet.  
The downdraft blower system is designed to  
use 3-1/4"x10" ductwork. It can be  
transitioned to 6" round.  
Ductwork MUST be vented to the outside–  
never into a crawl space, attic or other  
enclosed space.  
Refer to “Duct Fittings” chart to calculate  
equivalent length for various duct  
configurations.  
Determine the need for a wall cap or roof  
cap. Order the cap in advance.  
Gas and Electrical Locations  
Refer to “Power Supply Locations” page 8 for  
details.  
Plan the placement of the electrical outlet and  
gas carefully. Gas and electrical outlets cannot  
be placed on the back wall of the cabinet  
because it may interfere with the downdraft  
plenum.

Locations  
Do Not Locate Gas or Electrical  
Connections Within Shaded Area  
These cooktops are designed to operate on  
natural gas at 4" of water column pressure or  
on LP gas at 10" of water column pressure.  
These cooktops are shipped from the  
factory set for natural gas. If you decide  
to use this cooktop with LP gas, conversion  
adjustments must be made by a service  
technician or other qualified person.  
JXLP56 conversion kit is required for  
LP operation.

The pressure regulator must be connected in  
series with the manifold of the cooktop and  
must remain in series with the supply line  
regardless of type of gas being used.  
Gas Location  
For proper operation, the maximum inlet  
pressure to the regulator must be no more  
than 10" water column pressure for natural  
gas and 14" water column pressure for LP gas.  
When checking the regulator, the inlet  
pressure must be at least 1" greater than the  
regulator output setting.  
If the regulator is set for 4" of water column  
pressure, the inlet pressure must be at  
least 5".  
Electrical supply:  
•A properly-grounded 3-prong receptacle  
should be located within reach of cooktop’s  
four foot power cord.  
– Locate the receptacle inside the cabinet on  
the right side wall. See illustration.  
IMPORTANT: (Please read carefully).  
FOR PERSONAL SAFETY, THIS APPLIANCE  
MUST BE PROPERLY GROUNDED.  
The power cord of this appliance is equipped  
with a three-prong (grounding) plug which  
mates with a standard three-prong grounding  
wall receptacle to minimize the possibility of  
electric shock hazard from this appliance. The  
customer should have the wall receptacle and  
circuit checked by a qualified electrician to  
make sure the receptacle is properly  
grounded and has correct polarity.  
Where a standard two-prong wall receptacle is  
encountered, it is the personal responsibility  
and obligation of the customer to have it  
replaced with a properly grounded three-  
prong wall receptacle.  
If the regulator is set for 10" of water  
column pressure, the inlet pressure must  
be at least 11".  
For ease of installation, and if local codes  
permit, the gas supply line into the cooktop  
should be 1/2" or 3/4" ID flexible metal  
appliance connector, three to five feet long.  
Note: Purchase new flexible line. DO NOT  
USE OLD, PREVIOUSLY USED FLEXIBLE  
LINE.  
Make gas connection through rear wall, or  
on cabinet floor at rear, as illustrated.  
Do Not, Under Any Circumstances, Cut Or  
Remove The Third (ground) Prong From The  
Power Cord.  
Do not use an extension cord.

supply piping system at test pressures equal to  
or less than 1/2 psig.  
Turn on the gas. Check for leaks using a
