This is done via the natural draught system. All Element4 gas fires are tested for flue gas discharge through the wall (C11), through the roof (C31) or with flexible exhaust pipes through an existing chimney (C91) The diameter of the duct can be 150/100 mm or 200/130 mm, depending on the fireplace and the course of the flue gas duct.
• If the flue run is only running vertically with no bends then you can use a reducer so you can use 150/100mm or 6/4 inch flue on most Element4 fires – but not all For Element 4 fireplaces, to not reduce the flue diameter is preferable for optimal operation of the fireplace.

Flue calculation manual You do not have to include the first 3 N-bends (from vertical to horizontal) in your calculations. The next bends of type N are each counted as 1 horizontal meter in the THL. For a bend of type Q (horizontal to horizontal): •...
Flue calculation manual Flue calculation example The six questions of flue calculation To find out whether the desired flue configuration is possible for your fireplace, the following six questions can be asked: 1. In what category is the fire that is to be installed. Use the table in chapter 3 as a guideline .

Flue calculation manual Existing Chimney All Element4 gas fire places are CE approved with a C91 mark. This means that the fire can be installed with a flexible pipe in an pre-existing chimney, where the chimney is functioning as the air supply in a concentric flue system. The flexible pipe is the exhaust for the flue gasses.
