hi, i want to install a stove and want to have around a meter of black single 5 inch pipe coming out the top of the stove before going outside through the wall do i need to convert to twin wall before exiting through the wall.
Posted by Robin Harris on Tuesday, 7 January 2014Yes, switching to Twin Wall flue system will be required before exiting wall through to external.
what height will this kit cover when fitted, will I need more sections to cover 5 metres.to clear the roof
Posted by Robin Harris on Thursday, 19 December 2013The 5" Twin Wall External Flue Kit contains 2 x 1m straight flue sections. Any additional straight lengths, bends or fire stop kits should be added to your order as required. FYI, the maximum length of black enamel flue permitted from top of stove is 1.6m, before moving up to Twin Wall.
