Finish a high-ceiling installation with the JennAir W11522794 Hood Accessory, a premium wall-mount hood chimney extension kit designed to deliver a clean, built-in look when standard chimney pieces simply won’t reach. Crafted in sleek stainless steel to coordinate with select JennAir® wall-mount canopy hood designs, this extension helps create a seamless vertical run from hood to ceiling—ideal for statement kitchens where visual lines matter as much as ventilation performance. One standout advantage of this kit is its purpose-built fit for taller spaces, supporting installations in kitchens with ceilings approximately 10-1/2 ft up to 12 ft, giving you the flexibility to complete a professional finish in layouts that often require custom fabrication. Unlike generic extensions that can look mismatched or require modifications, this accessory is engineered to integrate with compatible hood models for a more precise, polished appearance and a more confident install. Another key differentiator is that it’s a factory-certified accessory, meaning it’s made to meet the brand’s intended specifications for compatibility and finish consistency—helping reduce guesswork during planning and avoiding the uneven gaps, color variation, or alignment issues that can happen with off-brand parts. The stainless steel exterior is designed to complement modern appliance suites while helping conceal ducting for a streamlined, architectural profile that elevates the overall kitchen design. If you’re upgrading your ventilation or completing a new hood installation in a taller room, the JennAir W11522794 chimney extension kit is a smart, design-forward solution that helps your hood look intentional, refined, and truly built for the space. For best results, confirm your hood model compatibility before purchase to ensure the correct fit and finished height.
