LG SIGNATURE - 36 inches - Externally Vented - Wall Range Hood - Stainless Steel

Hello, there! Thank you for sharing your question to us about the LG Wall Range Hood (HCEU3639X). No, there is no extender available for this chimney hood to fit an 11 ft ceiling height. The unit is designed for ceilings up to 9 ft 6 in. For taller installations, we recommend working with a licensed installer who can confirm safe alternatives, such as a custom fabricated chimney cover, while maintaining proper ventilation clearance. You can explore the full feature list and support details here: https://www.bestbuy.com/product/lg-signature-36-inches-externally-vented-wall-range-hood-stainless-steel/J7G5658P7Z.
