Hi is this duct ok to use as extraction for my oil fired boiler .outlet being on top of boiler then straight up through the roof .
Thank you for your question. If the temperature is less then 200degree c then this will be fine. If the temperature is higher than this then our stainless steel flue would be better for your application.

Hi, Could you specify any minimum support distance for this product please? For example, does the duct require supporting at each end of the 3m length when installed, or should supports be more or less frequent than that?
Thank you for your question. I would recommend using a split ring on either end of the ducting if supporting to the wall or suspension rings either end if suspending from the ceiling.
do you have a collar to fit over 150mm spiral duct to cover any minor damage where ducting passes through a wall.
