Does this fire need a flue to the outside

Thank you for your enquiry.

Yes, this Crystal fire must be connected to a suitable chimney or flue system to operate safely. It is designed for use with both Class 1 (traditional masonry chimneys) and Class 2 (prefabricated/twin-wall) flues. If your property does not currently have an appropriate flue, one would need to be installed before the fire can be fitted.
