GAS REQUIREMENTS
Natural Gas
This cooktop is factory-set for use with natural gas.
Propane Gas Conversion Conversion must be done by a qualified service technician. To convert to propane gas, use the propane gas conversion kit provided with the cooktop.
ELECTRICAL REQUIREMENTS
120 V, 60 Hz, AC only, 15 A fused, electrical circuit is required. A time-delay fuse or dedicated
circuit is recommended.
VENTING REQUIREMENTS
This cooktop must be exhausted outdoors unless using the duct-free filter kit (W10620783).
Refer to kit instructions for further information.
LOCATION REQUIREMENTS
- To ensure cooktop base clearance, cabinet side walls need to be wider than the cutout.
- A minimum clearance of 2″ (5.1 cm) is recommended between the blower motor and cabinet for proper cooling. A 6″ (15.2 cm) clearance is recommended for servicing access.
- An under counter built-in oven cannot be installed under this cooktop.
JX3 ™ DOWNDRAFT COOKTOPS WITH DUCT-FREE VENTILATION The duct-free filter kit (W10620783) is approved for use with JX3 ™ downdraft cooktop models JGD3536G, JGD3430G, JED4536G, JED3536G, JED4430G, and JED3430G. The kit filters the air from the downdraft system and ventilates the conditioned air into the room through the toe kick of the base cabinet. Do not ventilate the air from the downdraft system into the base cabinet, base cabinet pedestal, crawl space, wall or attic.

DUCTING REQUIREMENTS
| COOKTOP | DUCT LENGTH | DUCT SIZE |
| Gas | 10′ (3.0 m) or less* | 5″ (12.7 cm) diameter* |
| Between 10′ (3.0 m) and 60′ (18.3 m) | 6″ (15.2 cm) diameter | |
| 31/4″ x 10″ (8.3 cm x 25.4 cm) | ||

| 31/4″ x 10″ (8.3 cm x 25.4 cm) |
*Gas cooktops must use 5″ (12.7 cm) diameter for runs of 10′ (3.0 m) or less.
**May be used to vent straight out the back of the cooktop and directly through the wall.
CALCULATING MAXIMUM DUCTING LENGTH
- Maximum ducting length is 60′ (18.3 m).
- Each 90° elbow equals 5′ (1.5 m) duct.
- Use no more than three 90° elbows.
- Flexible metal vent is not recommended.
- Do not install two elbows together.
NOTES:
- For ducting runs up to 30′ (9.1 m), install cooktop as shipped.
- For ducting runs of 31′ (9.4 m) to 60′ (15.2 cm), remove the restricter ring on the blower inlet housing.
- For altitudes above 4500′ (1272.0 m), reduce recommended vent run by 20% for best performance.
THROUGH FLOOR BETWEEN JOISTS TO OUTSIDE
