“Had a 5kW Stove running on a rear exit with an external twin wall that consistently smoked back under refuelling and needed flue to be warmed on days when others in the showroom didn’t.

Had already tried adding extra height to the flue which was already above minimum height requirements with no joy.
Ashley very kindly sorted me a flue cube and the transformation is amazing!

No more spillage, no prewarming the flue, just perfect lighting and refuelling every time.

Have already and will continue to recommend this product to my customers who have similar issues.

Thanks Ashley.”
