Yes, it is possible. There are two ways to make the electrical connection: with the 3 x 1.5 cable (to be run outside the chimney up to the speed regulator) in order to extend the first metre attached to the chimney fan. Or you can make an internal connection to the chimney with our high-temperature resistant cable, which you can purchase separately by selecting the desired quantity in the drop-down menu according to how many meters you need.
