Yes, On our condensing boilers you can fit 90 degree bends to a vertical Flue systems. Note: A 90° bend is equivalent to 1.3 m length of Flue. If it is necessary to use a 90° bend in the vertical Flue, ensure the Flue above it is sloped towards the boiler to ensure that all condensate is allowed to drain from the Flue. The slope must be a minimum of 25 – 30 mm per metre.
