So disappointed with this product. I have higher ceilings and contacted the company to order an extension for the chimney. They sent me two pieces identical to the ones included (16 inch female to male pieces). The results are pieced together and look terrible. I contacted them to see if they would make a longer extension as they do for other models and was told I probably put it together incorrectly. I didn't. It will only piece together male to female. It's awful and I paid almost $150 for the " extension". Will need to pay a contractor to have a solution made to fix it. I would not order this again.
