A:Answer Hi there! Thank you for reaching out with your question about the LG STUDIO 1.7 cu. ft. Over-the-Range Microwave Oven, Model # MHES1738N. We understand your need for clarification on its venting options.
Yes, this model can indeed be vented outside. It offers three venting options: Roof Venting, Wall Venting, and Room Venting. However, please note that the required ductwork for outside ventilation is not included with the microwave. If you have existing round ductwork, you'll need to use a rectangular-to-round adapter and install a rectangular 3" extension duct to prevent the exhaust damper from sticking.
If you decide to go with wall or roof venting, you’ll need to adjust the blower, as the unit is shipped with the blower configured for room venting.
