FAQs

Hi, is this Dura DTW flue? or compatible with it. I need to increase the length of our existing flue to prevent blow back. The existing internal diameter is five inches and the external about eight inches. Does it come with a bracket? Many thanks ......

Hi there
Is this flu suitable to extend a pizza oven flu out of the top of a pergola and if so how far would you suggest it needs to be from a ceiling mounted speaker?
Thanks
Graham

Hi Graham,

This should be okay, but you would usually need a single-to-twin wall adaptor and locking band if connecting from a standard (single insulated) length of pipe,

The minimum distance required from combustibles is listed at "Enclosed: 70mm - Unenclosed: 50mm" but we would recommend as much distance as possible to avoid possible interference between heat and electrics
