Hi there, Could you clarify the thickness of the sheet metal base and also the material please? Will this product accommodate a flue diameter of 180mm? I'm looking to install the product onto a canvas yurt. Thanks!
The base is made of aluminium and can accommodate a 180mm flue. The thickness is approximately 3mm.
In regards to installation in a canvas yurt, we are not sure if this is a suitable solution - We would advise consulting with your HETAS installer prior to use.
