Installation Overview
Installing the Jenn-Air JXD7030YS downdraft requires careful planning and precise countertop fabrication. The primary cutout measures 28.5 inches wide by 10.5 inches deep with rounded corners featuring a 0.25-inch radius. The unit's overall footprint is 30 inches wide by 12.125 inches deep, requiring adequate cabinet space below for the motor housing and ductwork. The reversible motor box allows for flexible installation with the blower positioned on either side of the unit. Fabricators should ensure the countertop material is at least 1.25 inches thick for structural integrity around the cutout perimeter. The downdraft extends 14 inches above the countertop when fully raised, so verify adequate clearance if installing below overhead cabinets or shelving. Electrical requirements include a dedicated 120V, 15-amp circuit positioned within the cabinet base. For ventilation, the system accommodates either a 3.25" x 10" rectangular duct or 6" round duct, which can be routed through the floor or rear wall depending on kitchen layout.
CNC Cutting Notes
When programming your CNC for this downdraft cutout, precision is critical to ensure the unit seats properly and operates smoothly. Start by importing the DXF template and verifying all dimensions match the specified 28.5" x 10.5" opening. Use a 0.25-inch radius end mill or ball nose bit for the corner radii to match the manufacturer specifications exactly. For granite and quartzite, we recommend a cutting speed of 60-80 inches per minute with adequate water flow to prevent heat buildup and material stress. Quartz and engineered stone can typically handle slightly faster speeds at 80-100 IPM. Begin with an outside profile cut, maintaining a 0.010-inch tolerance for a snug fit without binding. Pay special attention to corner quality, as chips or irregularities can interfere with the mounting brackets. For brittle materials like marble, reduce feed rates by 20-30% and ensure proper support beneath the cutout area to prevent cracking as the center section releases. After cutting, perform a thorough edge inspection and use hand polishing to smooth any minor imperfections. Test-fit the unit before final installation to verify proper clearance and alignment with cabinet structure below.
Material Compatibility
This downdraft cutout template is compatible with all standard countertop materials used in residential and commercial applications. Granite and natural stone installations require standard diamond tooling with wet cutting to prevent thermal shock and edge chipping. The 28.5-inch width provides sufficient edge support even with full-height backsplashes. Quartz and engineered stone materials are ideal candidates, as they offer excellent structural stability around the cutout perimeter and resist heat from cooking activities. Solid surface materials like Corian require special attention to heat resistance, so verify the specific product's temperature rating exceeds 350°F for downdraft installations. Laminate countertops are generally not recommended for downdraft ventilation due to heat sensitivity and structural concerns, though high-pressure laminate with marine-grade substrate may be acceptable in budget applications. Concrete countertops work well but require additional structural reinforcement around the cutout and waterproof sealing to prevent moisture infiltration. Stainless steel and metal countertops are fully compatible and often used in professional kitchen settings. Butcher block and wood surfaces should be avoided in the immediate downdraft area due to heat and moisture concerns. For seam placement, avoid positioning seams within 6 inches of the cutout perimeter to maintain structural integrity.
Where to Buy
